Discovery of Deinonychus Dinosaur Changed Paleontology

The Discovery Of The Deinonychus Dinosaur
Deinonychus were discovered during the time period of Early Cretaceous, which was between 110 to 115 million years ago. When deinonychus were
discovered, paleontologists started to reconsider how dinosaurs lived. Deinonychus name comes from "terrible claw" (prehistoric Beast of the Week,
2015). This name was given because it was believed that deinonychus were active dinosaurs all year round (Blagic 2016). The discovery of the
deinonychus dinosaur was out of the ordinary. These features that the deinonychus had was never seen before in any other type of dinosaur. This
dinosaur was intelligent, fast, had claws that could slash a prey bigger than itself, and the hands could grasp the prey (Yale Peabody Museum of
Natural History,
Barnum Brown first discovered Deinonychus between 1931–1932. He found the Deinonychus bones. He collected their bones and body parts, like the
hands and feet from Crow Indian Reservation. Soon after when Brown died, John Ostrom took over and began the discovery again. He made his way to
Montana to rediscover Deinonychus in 1969. Ostrom found that deinonychus were much smaller than its cousin Tyrannosaurus Rex. Deinonychus
weighed around 50–100 kilos. (Lowell Dingus and Timothy Rowe, New York, W. H. Freeman and Co., 1998). A lot of information was found about
this one particular dinosaur, which leads to many hypothesis and experiments. The discovery of the features of a deinonychus dinosaur gives us
insights to the feeding behavior it retains and how

Majestic Dinosaurs
The title of the article I chose is Paleontologists probe the majestic reptiles' origin and rise writen by Alenxandra Witze. This article talks about
paleontologists excavating ancient fossils, giving them more information about the common ancestor of dinosaurs, and how they came to rule the
earth for millions of years. The author gives us an example of what the ancestor of dinosaurs may have looked like, by telling us that it "probably
looked something like a chicken". Just as there was a mass extinction that wiped out most dinosaurs, there was a mass extinction millions years before,
that gave the dinosaurs an opportunity to rise and evolve. 252 millions years ago, between the Permian and Triassic periods a mass extinction wiped
out most life on Earth. This gave the opportunity for new groups to ... Show more content on Helpwriting.net ...
The oldest piece of evidence showing that the first dinosaurs showed up during the Triassic time period, are the fossil footprints found that date back
250 million years, although not everyone is convinced that the footprints are definite evidence. Scientists are not sure how to classify some of the
earliest species found between the three main branches of the dinosaur family tree: Theropods( two–legged meat eaters),
Sauropodomorphs(four–legged, long neck plant eaters), and Ornithiscians ( "bird hipped" dinosaurs). Although these fossils help paleontologists
discover new information, new findings also come from close relatives of dinosaurs, just like "a long talk with an estranged cousin can help fill in
family history, these discoveries are illuminating how dinosaurs evolved alongside other animals". One of the relatives that helped with this process are
the silesaurids. Their bones help illuminate crucial differences between dinosaurs and their relatives deep in the

Dinosaur Dinosaurs: Extinct or Natural Causes
As geologic time goes, all the dinosaurs living on earth suddenly disappeared. How did these dominated and gigantic creatures really die? Was it a
slow extinction through natural causes, or did it happen suddenly? These questions give rise to many different beliefs on how the dinosaurs
disappeared over sixty–five million years ago. Something happened sixty–five million years ago, at the end of the Cretaceous period that was so
devastating that it altered the course of life on earth. Extinction is easily defined: the birth rate fails to keep up with the death rate. However, the
definition does not answer the question about the nature or causes of extinction. Since so many ... Show more content on Helpwriting.net ...
A massive eruption may have saturated the atmosphere with carbon dioxide so the that a sharp rise in temperature occurred worldwide. The excessive
carbon dioxide would have permitted solar energy to enter the atmosphere but would have blocked the radiation of most surface heat back into space,
causing the "greenhouse effect". rising temperatures could have killed off or reduced the activity of plankton, disrupting food chains and also
disrupting the plankton's normal role in converting carbon dioxide to oxygen through photosynthesis. It would have taken long for dinosaurs to
become extinct.
Dinosaurs may have also killed themselves. It is possible that they consumed poison from plants. The emergence of flowering plants could have
poisoned them. These plants contained alkaloids. Smaller animals with lesser appetites could have survived the doses, but perhaps the dinosaur could
not. Most mammals are smart enough to avoid these poison ness plants because of the bitter taste. The dinosaurs, however, may have not had the sense
or the liver. They could not taste the bitterness or detoxify the ingested substances. This theory is not scientifically significant because there is no way
of telling if the dinosaurs could taste, or how their digestive system worked.
What if it wasn't the dinosaurs that caused their own extinction, but something greater? Species of animals that have survived for millions of years
have to be well adapted to their environment or they

The Dinosaurs Of The Mesozoic Era
A traditional archeological dig, facilitated by new technological advancements uncovers raptor fossils by a team of researchers. This is how the
movie Jurassic park begins. It shows almost a foreshadowing of the events to come as the doctor looking at the technology shows weariness to the
usage of the machine to do the work they could have done by hand. Likewise, the Jurassic Park movie tells a story of an increased scientific presence in
the scientific study of the dinosaurs of the Mesozoic Era. Due to the ardent work of dinosaur researchers, dinosaurs are brought back to life for the
purpose of education and entertainment. With this financier and developer of the program, Jeff Hammond brings together a team of scientists, a
lawyer and two of his grandchildren on an adventure to experience the park first hand. However, due to a series of unfortunate events the parks loses
functionality resulting in their team having to physical experience survival during the time of the dinosaur. While half of the team fights to stay alive
the developer his group of survivors must find a way to rescue the visitors and get back in control of the park. I found the movie to be more
entertaining than educational. It was more for the purposes of telling a story, which I believe was about the power that genetics has brought humans.
The story seems to warn against going too far with the use of genetic information.This, in my opinion, is greatly exemplified by one of the last scenes
in the movie.

Surviving Dinosaur Extinction
The species that survived the dinosaur extinction are believed to be what life on this planet is descended from. Aligators, crocodiles, lizards and snakes
are among the reptiles that survived what dinosaurs couldn't. Birds also survived, and are the only descendants of dinosaurs that survived the mass
extinction other than lizards. Frogs and salamanders are among the few small amphibians that survived. Mammals also survived and they are the
largest group to survive the extinction. Over 50% of the world's population were thought to have died out in the course of this event. Many species
became extinct, some of these were marine reptiles, big amphibians, some reef–building creatures and some cephalopod molluscs.
Some possible theories for extinction

Arguments Against Dinosaurs
Argument 1
It is said that there has been rare and precious Dinosaur bones discovered in the Eromanga sea, this almost proves that Dinosaurs once roamed around
the shores. Also many of the significant events in Geological history, over the past 600 million years can be observed at Hallett Cove. Some of the
oldest rocks have been found in these seas. The finding of the Ediacaran could potentially mean that there can be dinosaur fossils found in the ocean, or
even that relatives of the ediacaran could be considered fossils and could be found in the sea.
Although the Ediacaran period was well before the first appearance of dinosaurs it shows that there were fossils many years ago. When dinosaurs first
appeared things had changed there was still shallow water which meant that bones could be fossilized. ... Show more content on Helpwriting.net ...
The reason for this is because a sedimentary rock is mainly because it is the only rock that would be able to keep the fossils form. If a fossil was to be
in a metamorphic rock in would be deformed because i metamorphic rock needs pressure which would then flatten the fossil. If it was to be in an
igneous rock the fossil would melt because an igneous rock is created from hot lava from

The Origins Of The Dinosaur Myth
For over a century, paleontologists have been collecting abundant dinosaur fossils from the Western Interior of North America, with many of these
fossils found in rocks dating back to the final stages of the Cretaceous Period. Only recently, however, have we learned that most of these dinosaurs
existed on a "lost continent" today referred to as 'Laramidia". (Switek, 2010)
Two new species of horned dinosaurs have been found in the Grand Staircase–Escalante National Monument in Southern Utah. The bigger of the two
new dinosaurs, Utahceratops gettyi, had a skull 2.3 meter (around 7 feet) long. The first part of the name combines the origin of the find and ceratops,
Greek for "horned face". The second part of the name honors Mike Getty, the paleontology

The Good Dinosaur
2015 seems to be the year for dinosaurs, what with the release of 'Jurassic World' earlier and now 'The Good Dinosaur'. While 'Jurassic World'
focused on the havoc dinosaurs could create, this movie revolves around the life of a timid and clumsy dinosaur born in a small family of working
dinosaurs. Directed by Peter Sohn, the movie features actors Raymond Ochoa, Jack Bright, Sam Elliott, Anna Paquin, and Steve Zahn in the voice over
for the dinosaurs. In today's world dinosaurs are extinct but what if, about 65 million years ago, the asteroid which eventually led to the extinction of
dinosaurs did not hit the earth and only affected them by grabbing their attention for a second as it swooped over the earth. With this assumption in

The Geologic Scale Of Dinosaurs
The earth has existed for about 4.6 billion years; the geologic scale divides all of these years into sections, much like chapters in a book. Each of
these sections is unique because it shows all of the changes on earth's surface throughout the years. The largest of these sections on the geologic scale
is eons. Eons are also divided into another two sections call ears. Eras are then divided into periods and then periods are divided into epochs. The
reasons why the sections have been divided are either because major organisms developed or went extinct. Organisms go extinct because they either run
out of space or food, or the environment changes making it hard for some organisms to survive the new environment (Ghose). Dinosaurs started
developing after a mass extinction of the Paleozoic Era just about 125 million years ago. Dinosaurs lived through the Mesozoic Era then later died off
during another mass extinction about 65 million years ago, starting the beginning of the Cenozoic Era. Almost all dinosaurs and half of the other plants
and animals went extinct, some scientist think that an asteroid hit the earth wiping out everything in sight. At the beginning of the Cenozoic Era,
which still continues today, scientist have a better understanding of this era because humans are living through it and are able to document everything
that happens throughout the years. (Gammon) When the average person thinks of dinosaurs they envision a big ferocious reptile. Which is mainly true

Dinosaurs Are Endotherms Summary
The author states that there is a considerable evidence that dinosaurs were endotherms and provides three resons. In contrast, the professor states that
many scientists have problem with the author arguments and she oppses each of the author's reasons. First, the article claims that one reasons for
believing that dinosaurs were endotherms is that dinosayrs fossils have been discovered in polar regions. However, the professor refutes this point by
saying that when dinosaurs lived in the polar regions, these regions were warm enough to have non endotherm animal to live there. She added that
when the climate became cold, dinosaurs migrated or habrinated to a warmer area. As aresult the presence of fossils in polar regions does not approve
that

Smell Of The Dinosaur Summary
Despite agreeing with the description about the dinosaur provided in the reading passage, the speaker claims that the hypothesis to justify the uses of
the Dinosaur's crest are not entirely true and he provides new conclusions about those three presented hypothesis.
Firstly, while in the reading passage it is stated that the Dinosaur's crest could be used to support the sense of smell of the Dinosaur, the speaker casts
doubt on this assumption. The speaker claims that the brain structure of the Dinosaur was not developed enough for sensing the smell through the
crest. Therefore, the speaker believes that it wouldn't be likely that the dinosaurs had used their crest to boost their sense of smell.
Secondly, in the reading passage it is proposed

Dinosaur Decay
Dinosaurs roamed the earth many million years ago while roaming parts of Maryland for many of their history here on earth. There were many
species that were predominantly found in this location. Around twelve species of dinosaur like animals can be traced back to these parts of Maryland.
Dinosaurs wandered in this area from Late Triassic to Late Cretaceous periods. Maryland had a distinct climate changes during these periods. Once it
was tropical and had volcanoes and changed to warm and shallow temperatures. Because of these temperatures we were able to find preservations of
these few dinosaur fossils. These fossils resisted decaying and were found in low lying areas and were buried in alluvial sediments. If they were not
destroyed by other

The Extinction Of The Dinosaurs Extinction
Imagine you were a dinosaur, living 65 million years ago. One day, you are going around doing what you do on a normal basis, when suddenly you
see a giant object coming towards the ground a few hundred miles away from you. Then suddenly, it goes black as gases block out all light except
for one light coming rapidly towards you. Other dinosaurs are running away from the light as you start following them. You look behind you to see the
light is quickly catching up to you as suddenly it catches you. You feel immense pain and then you are dead. I believe that the mass extinction of the
dinosaurs sixty–five million years ago was caused by an asteroid ten kilometers wide striking just off of the coast of the Yucatan peninsula, that
caused smoke to block out the sun and for fireballs to shoot across the sky. About 65 million years ago, an asteroid is said to have crashed off the coast
of the Yucatan peninsula. This crash is what some scientists believe to be the reason the dinosaurs went extinct. The first to believe that impact was the
cause of the extinction were the father–son duo of Luis and Walter Alvarez. They think that because of the crash the sun was blocked out by dense
clouds of dust. The crash also most likely didn't kill just the dinosaurs but, according to PBS, "...caused the extinction of just the dinosaurs, but of up
to 70 percent of all plants and animals living at the time." The asteroid was also most likely not traveling very slowly. It is believed it was

Dinosaurs : What Are Dinosaurs?
Part A: What are Dinosaurs?
Dinosaurs are land–dwelling reptiles that once roamed the Earth and the word comes from a Greek word that means "terrible lizard". Dinosaurs are
defined by their skeleton features, particularly the way they hold the limbs. Dinosaurs limbs support them from beneath, (like a horse), while
modern–day reptiles (such as crocodiles and lizards) limbs come out from the sides. Dinosaur are a diverse species ranging in different shapes and sizes
and were able to survive in a variety of ecosystems (Australian Museum, 2016) (Natural History Museum, 2017) (Dinosaur Jungle, 2015).
Dinosaurs are divided into two major groups based on their hip structure, the Saurischia (lizard–hipped) and the Ornithischia (bird–hipped). In ... Show

The skeleton consisted of Nine isolated teeth, left dentary (lower jaw), right and left upper ribs, partial right ilium, both ulnae (forearm), right forearm
bone, finger bones, claws, right femur (thigh), both tibiae (shin bones), right fibula (calf bone), right ankle bone, foot bones, foot claws.
Almost all the fossils were discovered at the bottom of a Billabong near the town of Winton, Queensland. The site was known as Billabong Bonebed,
where the greatest amount of dinosaur bones of the Australovenator and diamantinasaurus ever in Australia. In 1981 near Eagles Nest in southern
Victoria, a dinosaur bone was discovered and immediately recognised as an ankle bone of a theropod dinosaur. It was first thought to belong to a
dwarf species of Allosaurus, because of the similar features, but in 2009 it was confidently assigned as the Australovenator. The Australovenator was a
5–6m swift predator that stood about 1.6m high and unlike most theropod dinosaurs, the Australovenator had

There were over 1,000 different species of dinosaurs ("Dinosaurs") that lived and evolved for almost 185 million years ("Dinosaur Facts"). Dinosaurs
were some of the largest and most mysterious creatures to walk the Earth. Dinosaurs have helped scientists to understand the Earth and it 's past by
studying different types, how they lived, their characteristics and what caused their mass extinction.
When, where and how did dinosaurs live? Dinosaurs arose around 200 million years ago and lived and evolved for about 185 million years. There

After discovering dinosaurs, Paleontologists then had to classify and name the fossils and dinosaurs they belonged to.
The word dinosaur was invented in 1842 by Richard Owen. Dinosaur comes from the Greek word "deinos" and "sauros" which translates to
fearfully great lizard ("Learn about Dinosaurs"). Dinosaurs are always named in Greek and usually named after their unique fossils, where they 're
found, it's size or a person. Before a dinosaur can be officially named it must be approved by the International Commission on Zoological
Nomenclature. It's difficult to figure out how dinosaurs sounded, mated, behaved, what color/pattern they were and which ones are male or female.
Paleontologists have however been able to discover that dinosaurs hatch from eggs, their bones have growth rings which can help figure out their
age and that the larger dinosaurs lived for roughly 100 years and smaller ones for less. All dinosaurs evolved from other reptiles during the Triassic
period. Dinosaurs are either herbivores or carnivores and are divided into two major groups. Bird hipped, Ornithischian, or lizard hipped, Saurischa. In
the Saurischa hipped dinosaurs the pubis bone is down and to the front but in Ornithischian hipped it is point down and towards the tail ("Zoom
Dinosaur"). The next step was to examine how dinosaurs behaved and their characteristics.
Dinosaurs were some of the largest, heaviest and fastest animals to walk the Earth. The longest dinosaur was either the

it. The jokes were absolutely "dad jokes" which I believe keep you focused on the topic. They went over dinosaurs' characteristics, aesthetically and
anatomically and they also spoke about who created the names of the fossils and creatures. Tim Elam informed us about dinosaurs being similar
worldwide, with evidence of fossils, because the land was one at that time. Through time and division of land they began to adapt and change slightly.
They spoke about saurischian versus ornithischian. There are various different between these two orders but the most distinguishable ones are the hips.

Extinction Of The Dinosaurs
The mass extinction of the Cretaceous period
The debate over what happened to the dinosaurs have been one of the most controversial research topics in history. One minute, the earth was blooming
with countless trees and a healthy environment, then, in the period of seconds, all life on earth was wiped out, creating a mass extinction across the
globe (Bond, 2017). Discovering what ended the cretaceous period has been a major priority in the scientific world, however, with enough modern day
research, scientists have nailed the extinction of the Dinosaurs down to two major theories; the asteroid impact theory, and the volcanic eruption
theory, both being extremely alike.
As research has been undertaken, scientists have evaluated all possible theories, distinguishing that there are two major possibilities; the volcano theory
and the asteroid impact theory. Both theories are highly comparable, yet both have distinguishing qualities that indicate their differences. The Volcano
theory, affecting the wide–spread area of India has been proven as a major factor to the discovery of why the dinosaurs became extinct. Research
indicates that 65 million years ago, monstrous lava beds called Deccan traps covered the surface of the earth, over an area of 500 000 square
kilometres (Weishampel, 2017).
Each lava bed released unimaginable amounts of noxious gases, leading to a block of sunlight in the atmosphere, resulting in all plant life on earth
dying out. As a result of all plants having

small sign that reads, "Extinct." You discover that ninety–five percent of animal and plant life that were once main attractions of the zoo no longer

As far as extinctions of the past go, dinosaurs are the best known example of worldwide devastation of a single species. The origin of the dinosaur

that the reason for this mass extinction event is a natural

Explaining Dinosaurs' Extintion
Though there is not one definitive explanation to explain dinosaurs' extinction, there are various theories that attempt to account for the mystery of
their extinction. The theories that explain their extinction at the end of the Cretaceous period are the asteroid, the volcanoes, and the major climatic
changes. The most popular theory for the extinction of the dinosaurs is that the Earth was hit by an asteroid or a comet. Was the impact actually the
cause behind the dinosaur's extinction? Or was it something completely different? An analysis of the evidence surrounding the extinction of dinosaur's
reveals that there are several different hypothesis that give theory on what might have happened.
Over 65 million years ago, planet Earth consisted of an extraordinary species known as dinosaurs. During this time something extremely large hit the
earth, causing global devastation. "65% of all life on the face of the planet was snuffed out of existence and the dinosaurs that roamed the planet up to
that point were no more" (O'Neill, 2009). Curiosity has grown over the past hundred years, and scientists and researchers have given their life to find
out what exactly happened on that mysterious day. "A dinosaur extinction hypothesis is a testable statement describing factors that may have
contributed to the dinosaurs' demise and how long the process may have taken. Evidence, observation, and experimentation can serve to support or
disprove a hypothesis. Regardless of its ultimate

Extinction Of Dinosaurs Extinction
The extinction of dinosaurs could have been caused by many different things. One main reason that is thought around the world is that dinosaurs went
extinct because an asteroid fell onto earth at speeds that are too fast for the human mind to even imagine. This idea was thought when and asteroid
crater was found near mexico. Also to support the facts many scientist found traces of rare metal onto the earth's surface. This metal is not very
common here but is really common in outer space. Today we will be looking at why these huge creatures died of the face of the planet in just a matter
of months.
One reason, these greatebeastes were exterminated was that they alter the asteroid hit the ground a huge ball of dust and debris was sent into the earth.
This dust covered the earth in just a matter of hours. This was crucial to their extinction because the sun was blocked plants did not receive and sun
light and herbivorous ( plant eating animals) could not get any food from the plants because most of the plants died. This was just one of the first
reasons that the dinosaur race was wiped of this earth. You may ask how big the asteroid had to be, well put it into perspective the asteroid was about
the size of 110 empire state buildings and had the weight of 211,000 empire states buildings put together. This asteroid was the biggest asteroid to ever
hit earth that we know of. This big of a hit throw 70 billion tons of soot out of the earth and that dust polluted the skies. If

Dinosaur Art Essay
The Significance of Dinosaur Art
Dinosaurs are creatures that seem to fascinate humans, since all we have left are their fossils. Although, through art, their bodies can be put back
together and we have a better sense of what they looked like. The problem with art is that pictures can sometimes be disproportionate, unrealistic, or
even made up. Young children who learn about dinosaurs may think that they are actually different colors and can talk for example. This is why it is
important to make dinosaur art as realistic as possible and more informative.

Besides paying attention to new discoveries, paleo artists must notice how information is interpreted by different people. Paleo artist John Sibbick
states that a bunch of people could have the same scientific information and fossil evidence in front of them, but how they all interpret it is very
different. Everyone has a different artistic style, but the important thing is that their pictures clearly depict dinosaurs in an accurate environment with
the dinosaurs realistic themselves.
Through the years, paleo art has increased greatly, due to an increase in scientific findings and information being confirmed. The understanding of
dinosaurs has increased and "the art has changed to reflect that", said Sloan (2). One step to an increase in dinosaur understanding and art was in the
1980's. Paleontologist Robert Bakker came up with a theory that dinosaurs were warm–blooded. He thought that fossils looked more like
warm–blooded bones. Eventually his theory was accepted all over. This had a big impact on dinosaur art and then it encountered a drastic change.
Instead of dinosaurs standing around and doing nothing but eating, they were now running and hunting their prey. The art changed from still life to a
more action filled art, which appealed to more people and made the lives of dinosaurs seem more complicated than originally believed.
After Robert Bakker's theory, was the discovery of small and medium–sized dinosaurs that were found in northeastern

Dinosaurs Case Study
Digging Dinosaurs
Level A:
You are swimming underwater in a lake and you see dinosaur feet in the water. You don't want to go to the surface of the lake in case they are not
friendly dinosaurs.
How many dinosaurs are standing in the lake? Explain how you know. Use words and mathematical language to explain your solution..
Problem Restated: This basically states try to find all possible combinations and outcomes for this type of situation.
Process: The very first thing I did was to find out that there weren't any dinosaurs with 1,3,5,6,7,8 feet. (Lincoln and John helped with that). Next, I
figured that if there were only two–legged dinosaurs it would be four of them. 2+2+2+2=8. There could also be four–legged dinosaurs. In this case 4 x
2 = 8 found the number of dinosaurs. Last, there could be a combination of dinosaurs in the lake. A four–legged and two two–legged beasts.
Math:
2 four–legged dinosaurs make up eight feet or 4 + 4= 8
4 two–legged dinosaurs make eight feet or 2+2+2+2=8
1 four–legged dinosaurs and 2 two–legged dinosaurs make 8 feet or 4+2+2=8
Solution: A possible four two–legged, and two four–legged, as well as one four–legged and two two–legged. So 2,3,4 dinosaurs

The passage and the lecture discuss whether dinosaurs were endotherm or not. Although the author has proposed clear demonstrations which indicate
that dinosaurs were endotherm, the lecturer takes issue which what has been proposed by the author and believes that these evidence cannot prove the
claim. According to the passage, dinosaurs were endotherm because they some of them lived in the polar region and only endotherm animals could live
in such a cold environment. The lecturer contradicts this theory and asserts that polar regions were warmer in those days and dinosaurs also could
migrate during cold periods or hibernate just like many modern reptiles. Secondly, the author points out that leg position of dinosaurs could be another

Dinosaurs And Birds Essay
Dinosaurs and Birds
Are birds really dinosaurs or are they simply related? That is a question that has gained new life in recent years due to the overwhelming facts the
are pouring in from newly found fossils and studies from fossils that have been found in the past. Two groups have formed in the study of this
question: those who believe birds are a direct result of dinosaurs and those who feel dinosaurs and birds must have had a common ancestor.
Determining which view is correct is a matter of opinion based on fact. The main problem involves the use of cladistics or phylogenetic systematics to
group organisms according to characteristics they share. When one looks at dinosaur fossils, he or she may feel that certain ... Show more content on

Also, support is gaining that Archaeopteryx was not in fact the first bird, but instead a descendent of an earlier bird ancestor that had developed along a
different pathway and actually represents an evolutionary dead end.
Two opponents of the "birds are dinosaurs theory" are Alan Feduccia of the University of North Carolina and Larry Martin of the University of
Kansas. They believe that birds evolved from some unknown reptile from a time before dinosaurs came to be. One point they make is that flight
must have begun from tree climbing or an arboreal ancestor but that all the proposed dinosaurian ancestors were ground dwellers or cursorial On the
other side, supporters for the "birds are dinosaurs theory" feel there is an unknown dinosaur bird that was arboreal, or simply that birds evolved flight
from the ground by chasing after insects.
In recent years other fossil finds have stirred the argument even more. One of these is the fossil named Sinosauroptyrex found in China. It appears to
be an important link between birds and dinosaurs. Sinosauropteryx appears to be a feathered dinosaur having a mane of feathers along its neck, back,
and tail–a feature until then seen only in birds. Sinosauroptyrex appears before Archaeopteryx and gives a substantial link between the theropods and
birds. One opponent of this find is Martin who feels the

Rapid climate change also ends up on the suspect list of possible dinosaur extinction events. During the latter part of the Cretaceous Period continents
broke up causing volcanoes to erupt and fill the sky with gas and ash resulting in a drastic climate change ("Dinosaurs Climate Change and
Biodiversity"). The shifting of continents changed the Earth's landscape, altering weather patterns and overall climate ("Dinosaur Extinction Theories").
Also, over a long period of time, climate gradually changed. Ocean habits changed, temperatures grew much more extreme causing scorching summers

They say as mammals continued to evolve, they drove the dinosaurs into extinction ("What Killed the Dinosaurs"). "Not only did mammals likely
compete with dinosaurs for resources, many species survived the end–Cretaceous extinction and subsequently came to dominate Earth." ("What Killed
the Dinosaurs?"). This is primarily because the early mammals were a lot smaller than the mammals that exist today. "Some of the world's earliest
mammals were the multituberculates, a group of small rodent like animals that first emerged on Earth about 165 million years ago." (Welsh, Jennifer).
Scientists predict that any mass extinction event that caused animals to go extinct affected larger animals than it did the smaller animals, such as
mammals ("Dinosaurs Became Extinct 'due to Laying Eggs'"). Mammals remained small for almost 100 million years, while they out competed
small and baby dinosaurs for food, shelter and resources until they were extinct. Once the dinosaurs were out of the way mammals were able to
evolve and grow large in size like the mammals that exist today today (LiveScience). Fossil evidence sheds some light on this theory as well. Fossils
of mammals believed to date back to about eighty five million years ago show that mammals began to change rapidly and grow. "This matches up with
other mammal groups, including recently discovered species from the Late Cretaceous (between 100 million and 65 million years ago) showing highly

Stereotypes Of Dinosaurs
Through excavating in bone beds it has become apparent that dinosaurs were more than singular animals and followed patterns displayed by many
current animal groups when concerning family. Dinosaurs had ranks within their herds and there where often struggles of territoriality, social
dominance, court–ship, and feeding (Tanke & Currie, 1998, pg. 181. These insights have been gained from light tooth scars around the snout and on
top of the skulls of many dinosaurs. While family units where common among herbivores, theropods also had herds, though they where often smaller in
size. Among herbivores herding was often a means of protection for both adults but also young and un–hatched eggs (pg. 167). However, one example
of a smaller herd was among

The Discovery Of The Dinosaur
Zhenyuanlong Suni was dinosaur that was officially announced on July 2015 when the official scientific report (written by the paleontologist who
studied it) was published. The dinosaur was given it's name after Zhenyuan Sun who took it's fossils for a deep study upon being discovered by a local
farmer. The fossils were taken to Jinzhou Paleontological Museum by Zhenyuan Sun for further examination. The specimen was further studied by
paleontologists Stephen Brusatte of the University of Edinburgh in the United Kingdom and LГј Junchang of the Chinese Academy of Geological
Sciences in Beijing. According to researchers Zhenyuanlong Suni is the largest winged dinosaur to be discovered so far, and it was known to be
carnivorous. In this paper we will examine the time period which it lived, the climate and the area, and finally it's unique anatomical features.
Based on the researches and labs' results, it is determined that Zhenyuanlong Suni lived in the Mesozoic Era. This is one of the newest species of
dinosaur that had been recovered. Its fossils was estimated to be at around 125 to 130 million years old. This bring us to a conclusion that
Zhenyuanlong Suni exist during the Barremian Stage of the Early Cretaceous Period. Zhenyuanlong Suni was among the many other reptile and
dinosaur fossils in the Yixian formation.
The Zhenyuanlong suni is a recently discovered dinosaur in Northeastern China. It was found in sedimentary rocks in the ancient lake beds in Sihedang

Argument On Dinosaur
Argument 1: Why I believe there is dinosaurs in my backyard because back when there was dinosaurs there was a shallow sea around hallett cove
south Australia which it would be where we are right now.
Why is this an important point? This is an important point because you need a large amount of water to make sedimentary rocks.
What factual evidence do you have to support your point (reason)? Because i have and people have found dinosaur bones around south australia befor.
Argument 2: Why I believe this point (reason); some elaboration and evidence.
What is the point (reason)? I believe this because no one has dug under our house because thats our house and we can't dig like 300m under our house
to find dinosaur bones.
Why is this an important point? Well no one has tried to find dinosaur bones around our place befor.... Show more content on Helpwriting.net ...
Well i have found rocks around my place befor and it has had fossils in it.
Argument 3: Why I believe this point (reason); some elaboration and evidence.
What is the point (reason)? If you go to the beach you can find rocks that have fossils in them and you can find them in the cliff around the beach.
Why is this an important point? That tells us that there can be fossils around our place or even dinosaur bones.
What factual evidence do you have to support your point (reason)? My evidence is that i have found fossils done at the beach.
Conclusion: And that is why i believe there are dinosaurs in my backyard and how there was a shallow sea where we are right now. And that is my
evidence that there is a dinosaur in my

The Extinction Of Dinosaurs
Cribbins 1 Hook. The extinction of dinosaurs is a mystery in itself that has stumped scientists all over the world for decades, and they still look for new
answers every day. Scientists know some background information, but cannot connect the dots to see the bigger picture. There was little interest in the
topic until Luis and Walter Alvarez proposed a groundbreaking hypothesis, which today we call the "Alvarez Hypothesis". This new idea of the
Alvarez's was exciting, and therefore got the media talking about it, which in turn started the search of how the dinosaurs went extinct. Another popular
theory of how dinosaurs went extinct is the Volcanism Theory. Scientists have recently found new evidence supporting both sides of this debate.
Although many dinosaur extinction theories exist, only the Alvarez Hypothesis is correct. Scientists abase their extinction theories off one of
commonly known piece of information: that there was a change in climate around the time of the K–T boundary. Both major theories support this idea,
and both believe that something blocked out the Sun for many months. This stopped the photosynthesis in plants, the base of the food chain. Without
plants, the food chain was majorly affected. A domino effect happened, and one species died out after another. Eventually all species of dinosaurs died
out. Scientists know that there was a global climatic change, but are not sure how it happened. The topic of the K–T Extinction received little

Dinosaurs Extinction
New York, September 28, 3010 one of the biggest days in science history. Five kids named Zayn, Derek, Suzie, Casey, and Sophia have just
discovered how to bring back dinosaurs back from extinction. Zayn the kid who thought of this idea was kind of nervous when he and his peers made
a genetically modified dinosaur egg. But he was still proud of him and his friends about their scientific creation. The government demanded more of
these mutations so the United States of America would receive tons of visitors because of this new attraction which means more money for our
country. The government built a huge park with many enclosures for all the dinosaurs that the kids created after a few days. Couple months went by
and the eggs started hatching and the dinosaurs were put in enclosure. The park opened up and the kids were presenting what happens at the park to
the audience. During the presentation Suzie got a message from one of the managers of the enclosures saying that there was a dinosaur loose from
enclosure 12 which is the biggest dinosaur which is a spinosaurus.
The US army came to the park and tried to stop the dinosaur and pin him down. That turned out horrible the soldiers were eaten alive and a
mysterious guy from the crowd came in from outside the park and shutdown all of the enclosures and the dinosaurs broke out. The five kids found the
guy and interrogated him for a long time while the employees were trying to settle down the dinosaurs. Apparently the guy was

The Extinction of The Dinosaurs
Extinction of Dinosaurs Many different theories exist as to why the dinosaurs went extinct. We know for sure most dinosaurs died out around 65
million years ago. The majority of scientists agree on a number of theories as to what brought the end of the dinosaurs. The most popular theory is that
an asteroid ended the reign of the dinosaurs. Another theory, massive climate change in the pre–historic atmosphere, caused all the dinosaurs to die.
Some scientists believe that mammals out competed dinosaurs for food and other resources. The last theory that dinosaurs died due to a large amount
of volcanism comes up in scientists list of theories as well. Many different theories of why dinosaurs went extinct include extinction by asteroid,... Show

The power and magnitude of the asteroid is greater than we could ever imagine. If all the world's atomic weapons went off simultaneously it still
wouldn't cause as much damage as this asteroid did (Erdman). The enormous impact forced large clouds of dust into the air, these clouds blocked the
sun causing darkness and extreme climate changes ("What Killed the Dinosaurs"). Out of all the extinction theories the asteroid theory has the most
evidence backing it up. As time movies by layers of rock form in the Earth's crust. The rock formed in the layer around formed the time of extinction
contains abnormally large amounts of iridium, a metal found only in asteroids (Erdman). Another piece of evidence found in the rock is impact ejecta.
Impact ejecta results from an explosion instantly melting bedrock and throwing it into the air. An abundance of impact ejecta in the rock layer formed
near the dinosaur's extinction suggests that a large asteroid destroyed the dinosaurs ("What Killed the Dinosaurs"). Scientists can locate a layer of
rock that formed during extinction because all fossils of a certain species show up under or in a rock layer but never above ("What Killed the
Dinosaurs"). "The crater–like shape of the area, the layer rick in iridium and the age of the rocks all lend weight to the theory" ("Eden Channel"). Figure

Characteristics Of Dinosaur
Dinosaurs are a group of reptiles that first appeared during the Triassic period (around 225 million years ago) and were extinct in the Cretaceous
period (about 65 million years ago). Dinosaur are a diverse species ranging in different shapes and sizes and were able to survive in a variety of
ecosystems (Australian Museum, 2016) (Natural History Museum, 2017) (Dinosaur Jungle, 2015).
The fundamental physical features of a dinosaur are:
Diapsid (animal with two holes in skull behind eye socket)
Vertebrates (animal with a spinal cord surrounded by cartilage or bone)
A hole in the skull between the eye socket and nostril
Ankle that bends in single plane
A secondary palate that allows dinosaurs to eat and breathe at the same time
A large hole in the hip socket
Limbs held directly under the body
Three or more sacral vertebrae
Part B: Dinosaurs Example
Australovenator
The Australovenator is the most completed skeleton of any Cretaceous carnivorous dinosaur ever found in Australia with approximately 25% of the
bones recovered and prepared. The skeleton consists of two nearly complete forelimbs and hind limbs, along with isolated ribs, gastralia and both
dentaries. The fossils were discovered at the bottom of a Billabong near the town of Winton, Queensland. The Australovenator was a 5–6m swift
predator that stood about 1.6m high and unlike most theropod dinosaurs, the Australovenator had massive arms and hands with two of its three hand
claws being razor sharp weapons (Age

Theropod Dinosaurs
Birds have been around for a long time. We see them every day and everywhere we go but have you ever stopped and wondered where they came from
and how they fly? Paleontologists, ornithologists, and other scientists have been trying to understand where birds came from, understanding feathers,
and why, when, and how birds fly. Most of these questions are still being studied today.
The origin of birds began during the Mesozoic Era in the Jurassic Period, about 200 Ma (million years) to 146 Ma ago. All birds today were derived
from theropod dinosaurs. Theropod dinosaurs include some of the most recognized dinosaurs today including, Tyrannosaurus, Velociraptor, and
Spinosaurus. The relation between theropod dinosaurs and birds came from the discovery ... Show more content on Helpwriting.net ...
After the discovery of Archaeopteryx it became the "missing link" in connecting the dots to where birds derived from. From studying the earliest
feathers and coming up with theories as to why a bird evolved to fly are vital questions that yet to be understood and answered

Endothermia Condition In Dinosaurs
The reading passage discusses an interesting topic about the possibility of the endothermia condition in dinosaurs and provides three reasons for
support. However, the lecture cast doubts on the claim made by the article and opposes each of the reasons of the reading passage. First, the reading
passage sustains the idea of endothermic dinosaurs on the fossils discovered in Polar Regions, meaning that only this type of animals could survived
in such low temperatures. On the contrary, the lecture refutes this idea by arguing that the area where the fossils were discovered was warmer back in
those days when dinosaurs were alive. Moreover, as many reptiles today that live in areas with cold winters, the dinosaurs could migrate or hibernate
escaping

Dinosaurs Are The Endotherms-Birds
The reading and lecture, both are discussing that the dinosaurs are the endotherms– animals which keep their body temperature constant. The author of
the reading passage believes that the dinosaurs are the endotherms; whereas, the lecturer does not agree with the author. She puts forth three aspects,
each of which has dismissed the reading assertions. To begin with, the author of the reading asserts that the finding of the dinosaurs fossils in the polar
region are convincing. The author believes that the animals require to maintain the temperature higher than the surrounding temperature to live in the
low temperature area . This point is directly challenged in the lecture. The speaker posits that the temperature of the polar region in the time

Dinosaurs Are Awesome
If I had a time machine, I would want to go to a very famous time 67 million years ago. Although no humans were living during that time, I still
want to see how different earth was during that time so I could confirm and add to the overall knowledge about the dinosaurs. The Cretaceous time
period was the last time period in which dinosaurs are seen. This time period spanned from 144 million years ago (mya) to 66 mya; right after the
Jurassic time period and before the Tertiary. This is a time when dinosaurs were at their height with many thousands of different species known or yet
to be identified. Our earliest ancestors were small rodent–like mammals that lived during this time and gradually evolved into the many different types
of mammals we see today. The dinosaurs though, would become small reptiles such as the lizards we see today after one of the greatest known
extinctions of all times–the K–T Extinction also known as the extinction of the dinosaurs. In this time, I would see many giant dinosaurs such as the
T–rex. These dinosaurs would be competing for their own survival and their children's survival very roughly by killing other dinosaurs who get too
close to their nests or them. During this time, I would be wondering how did these giant creatures 30 feet tall die and have us puny mammals take their
place as the dominant species? I would then recount that thanks to a combination of a massive asteroid hitting earth, mammals, deadly diseases,
volcanoes, flowering

Dinosaurs As Endotherms
The reading and the lecture are about endotherms, which are living organism capable of maintaining body temperature irrespective of their surrounding
temperature. The author reports that new evidences have come to light making dinosaurs more likely to be endotherms. The lecturer is against this
belief. He states that the new evidences aren't enough to consider dinosaurs as endotherms. First of all, the author contends that polar dinosaur fossils
are great evidences that dinosaurs are endotherms. This is because only animals capable of maintaining a high enough body temperature will be able
to move in the polar regions. The lecturer believes otherwise. He mentions that the polar regions weren't as cold as they are now. In addition, the polar

The fall of Dinosaurs
It is hard to imagine that millions of years ago, the Earth was not dominated by humans, but by Dinosaurs. These great Beast's, who were as big or
bigger than cars, roamed the land. Some were giant killing machines, like the Tyrannosaurus Rex.Some are even alive today, while many people do not
even notice. There have been countless theories as to how the dinosaurs became extinct.
The dinosaurs ruled the land for millions of years, and it seems impossible that such magnificent creatures could have been taken off the earth.
Dinosaurs were very adaptable to their environment and traversed the entire earth. They were even found on lands like Antarctica, and many different
oceanic islands like north Island, New Zealand, and a island called Spitsbergen.(Creation.com/Oard) There have even been Dinosaur fossils found in
northern Alaska next to the arctic Ocean.(Oard) These questions have perplexed researchers, and it has made them wonder if dinosaurs were
Endotherms, Ectotherms, or some combination in between.(Oard) An example of this is a comment from researcher Michael Benton," Should we now
imagine Dinosaurs as thermally insulated Warm–Blooded animals that ploughed through the snowdrifts and scraped brush the ice off the ground to find
food?".(Oard)
For the past several years, Different dinosaur tracks have been discovered at over 1,500 locations from around the world.(Oard) The number of tracks
are in the
