According to a recent study, T. rex and other theropod dinosaurs may have had lips, which contradicts the popular belief that they had teeth jutting out of their mouths.
Here are 3 interesting facts about dinosaurs from the passage:
1. The largest dinosaur was likely the Brachiosaurus, which could grow up to 80-85 feet long and weigh around 80 tons. Some other dinosaurs like Seismosaurus may have been larger but only partial skeletons have been found.
2. Scientists estimate dinosaurs could have lived up to 150 years based on growth rings in their teeth, though this lifespan estimation is not certain.
3. Despite the huge size of some dinosaurs, their eggs were relatively small - even the eggs of the gigantic Sauropods were no bigger than volleyballs. Thicker shells posed problems for the hatchlings to breathe and be pushed out of the shell
1) A geology professor and his students from Colorado College travel each summer to fossil sites in the Midwest and West to collect dinosaur teeth.
2) By analyzing the chemical composition of the enamel on the teeth, they can learn about the dinosaurs' diets and environments.
3) Their research has provided evidence that different dinosaur species ate different plants rather than competing for the same food sources, and that dinosaurs tended to remain in localized areas rather than migrating long distances.
This document provides an overview of a CLIL (Content and Language Integrated Learning) project on dinosaurs for a primary school in Italy. The project aims to teach subjects in English to develop basic skills like vocabulary related to the prehistoric era and dinosaurs. It describes activities like watching videos and songs in English with subtitles to aid comprehension, and having students work in groups to research vocabulary and create materials like timelines and information sheets on different dinosaurs.
This research project investigates how Americans construct meaning from dinosaurs through surveys, interviews, and observations at museums and dinosaur sites in Colorado. The researcher found that dinosaurs spark interest because they combine mythical and monster-like qualities with scientific facts. People are fascinated by dinosaurs' immense size and ferocity. Through studying public perceptions of dinosaurs, one can learn about societal values. The researcher gathered information by surveying museum visitors and coding interview transcripts. Common views were that dinosaurs like T-Rex were immense, violent, and carnivorous, while Velociraptor was swift and intelligent. However, some see dinosaurs as less exotic knowing of their evolutionary connection to modern birds. Perceptions may be influenced by popular media like Jurassic
This article discusses the evolutionary relationships between mammals, their ancient relatives known as synapsids, and reptiles. It aims to clarify misunderstandings caused by outdated terms like "mammal-like reptiles". The article explains that evolutionary trees show synapsids like Dimetrodon are more closely related to mammals than reptiles, despite some superficial reptilian appearances. It also notes that non-mammalian synapsids displayed great diversity beyond a simple linear progression towards modern mammals. Key characteristics evolved at different times among synapsid subgroups.

The document discusses three hypotheses presented in a reading passage about the uses of a dinosaur's crest. It casts doubt on each one. First, it argues the dinosaur's brain was not developed enough to use the crest for smell. Second, it does not provide the full hypothesis from the passage. Third, it similarly does not state the full hypothesis.
Ancient Wildebeest Cousin Boasted Bizarre Dinosaur-like Trait.pptxBraydenStoch2
Researchers discovered that an ancient cousin of the wildebeest called Rusingoryx had a bizarre crescent-shaped protrusion on its head unlike anything seen before in mammals but similar to duckbilled dinosaurs. This hollow structure may have enabled the animal to produce low trumpeting sounds to communicate over long distances with other herd members, similar to how hadrosaur dinosaurs are believed to have communicated. Examination of Rusingoryx skulls revealed the crest contained nasal passages that could have allowed vocalizations to be produced at infrasound frequencies inaudible to predators, aiding safer communication.
Ostracoderms were early jawless vertebrates that lived from the Cambrian to the late Devonian period. They were covered in bony plates and resembled modern hagfish and lampreys. While some evidence suggests they lived in freshwater, their habitat is still debated. Later in the Devonian, jawed fish evolved from ostracoderms and outcompeted them, contributing to their extinction by the end of the period. Ostracoderms were divided into two main groups and played an important role in the early evolution of vertebrates.

The document discusses facts about different dinosaurs, including that the Amurosaurus lived near the Amur River, Andrewsauchus was discovered and named after paleontologist Dr. Roy Chapman Andrews, and while dinosaurs were dominant on land, other reptiles like archosaurs and therapsids predated them. It also provides the three main time periods dinosaurs lived in, the meaning of the name Deinonychus, why some dinosaurs ate rocks, what scientists can learn from studying teeth, and promotes a dinosaur toy line.
This document provides an overview of a digital book that sets up hypothetical battles between different dinosaurs. It describes some of the battles that are featured, such as Herrerasaurus vs Allosaurus, Deinonychus vs Stegosaurus, and Tyrannosaurus vs Triceratops. It also gives instructions on how to use the interactive digital book to learn more about each dinosaur's features and stats and decide who would win in each battle.
For the last 20 years, archaeologists have discovered many feathered dinosaur fossils in China that have helped reveal the original colors of dinosaurs. A recent discovery of preserved melanosomes, or pigment cells, on fossilized feathers is allowing scientists to map the colors and patterns of dinosaurs like Anchiornis for the first time rather than relying on educated guesses.
The document discusses several types of dinosaurs:
- Tyrannosaurus Rex (T-Rex), a large carnivorous bipedal dinosaur.
- Ankylosaurus, a wide herbivorous dinosaur covered in armor plates.
- Triceratops, a herbivorous dinosaur with three horns on its head that can be compared to a modern rhinoceros.
- Stegosaurus, an herbivorous dinosaur with bony plates along its back and spikes on its tail.
- Pterodactyl, a flying reptile that lived alongside dinosaurs.
The document states that Triceratops "can be compared to the modern day rhinoc
- The origins of birds has long been debated, with some believing birds evolved from dinosaurs while others believe they evolved from an unknown reptile.
- In the late 1800s, Thomas Huxley first proposed that birds evolved from dinosaurs after noticing similarities between dinosaur and bird bones. However, this theory fell out of favor for decades.
- In the 1960s, John Ostrom provided new evidence of similarities between dinosaurs and birds, reigniting the debate. Most scientists now agree that birds evolved from feathered theropod dinosaurs based on over 85 shared characteristics found over the past few decades.
The document discusses several theories about what caused the extinction of dinosaurs. One theory is that a severe ice age caused temperatures and water levels to drop dramatically, creating conditions dinosaurs could not survive. Another popular theory is that an asteroid impact wiped out the dinosaurs. The document also describes different types of dinosaurs, including herbivorous and carnivorous species, and what types of plants and other dinosaurs they preyed upon in the food chain.
Dinosaurs were the dominant land animals for over 160 million years, from the late Triassic period until the end of the Cretaceous period. They exhibited great diversity, with over 500 known genera and more than 1,000 species. Birds evolved from feathered, winged theropod dinosaurs and are the only living dinosaurs today. The extinction of most dinosaur species occurred during a mass extinction event at the end of the Cretaceous period, around 65 million years ago.
The document discusses the history of paleontology and robotics, and how recent advances in these fields have led to the creation of robotic dinosaurs. It describes Peter Dilworth's creation of Troody, the first robotic dinosaur in the US, which took 5 years to develop and could walk thanks to spring-like joints and force control sensors. It also discusses how 3D printing is now allowing scientists to create accurate models of dinosaur bones to better understand dinosaur anatomy and movement, with the goal of developing robotic dinosaur limbs. The document concludes by describing a theme park called Field Station: Dinosaurs that houses dozens of life-size robotic dinosaur species in a natural setting.
This is a slideshow about feathered dinosaurs, the early ancestors of birds. Scientists have found a number of similarities between dinosaurs from the Jurassic period and contemporary birds - everything from the skeletal structure to the possibility of flight.

Evolving Lifecycles with High Resolution Site Characterization (HRSC) and 3-D...Joshua Orris
The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.
The modification of an existing product or the formulation of a new product to fill a newly identified market niche or customer need are both examples of product development. This study generally developed and conducted the formulation of aramang baked products enriched with malunggay conducted by the researchers. Specifically, it answered the acceptability level in terms of taste, texture, flavor, odor, and color also the overall acceptability of enriched aramang baked products. The study used the frequency distribution for evaluators to determine the acceptability of enriched aramang baked products enriched with malunggay. As per sensory evaluation conducted by the researchers, it was proven that aramang baked products enriched with malunggay was acceptable in terms of Odor, Taste, Flavor, Color, and Texture. Based on the results of sensory evaluation of enriched aramang baked products proven that three (3) treatments were all highly acceptable in terms of variable Odor, Taste, Flavor, Color and Textures conducted by the researchers.
Kinetic studies on malachite green dye adsorption from aqueous solutions by A...Open Access Research Paper
Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.
Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...Joshua Orris
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.

T. Rex had lips? A new study suggests yes | The Lifesciences Magazine
1. T. Rex had lips? A new study
suggests yes
According to a recent study, T. rex and other theropod dinosaurs may have had lips, which
contradicts the popular belief that they had teeth jutting out of their mouths. For a long time, both
paleontologists and paleoartists have debated whether these carnivorous dinosaurs had lips.
Reconstructions by scientists in the 1920s and ’30s showed them with flesh over their teeth, but
popular media, such as the 1993 movie Jurassic Park, popularized dinos with large, prominent
teeth and no lips.
What further research suggests
To investigate this further, Thomas Cullen, a paleobiologist at Auburn University, and his
colleagues analyzed the relationship between skull length and tooth size of living reptiles,
including Komodo dragons, and several theropod dinosaurs such as the Velociraptor and T. rex.
They found that their teeth were not too big or too long for their skulls, similar to living lizards,
and thus didn’t have to stick out of their mouths.
The researchers also compared the enamel thickness of a dinosaur tooth with that of a crocodile.
They found that the crocodile tooth had a significantly thinner layer of enamel on its outside than
the dinosaur tooth, suggesting that the dinosaurs likely had lips that protected their teeth from the
elements.
Finally, the team compared the skull anatomy of lizards, iguanas, dinosaurs, and crocodiles.
Although birds are the closest living relatives of theropods, they don’t have teeth. So, the
researchers compared the features of iguanas and monitor lizards, both of which have lips, with
2. dinosaurs and crocodiles. They found that dinosaur skulls much more closely resemble those of
the lipped lizards and iguanas, suggesting that theropod dinos must have also had lips.
The Moment the world discovered T. Rex had lips
Not everyone is convinced
Emily Lessner, a vertebrate paleontologist at Denver Museum of Nature and Science, who was
not involved in the study, said, “This is a nice, concise answer to a question that has been asked
