Elementary School Student Report on T Rex

Published in: Lifestyle, Education, Technology
  • Nice presentation, Mr. T is a favorite because I have found his traces near my home in Calif. The coprolites are very chunky, and have large pieces of bone in them, as well as tenderized pieces that weren't sliced thinly like the other carnivores. Mr. Rex also left his signature on some unfinished hunks of meat, bringing the two digits together to butcher it's prey. That looks like the letter Y.

T Rex

  1. 1. The Amazing Tyrannosaurus Rex By Nathaniel Michael Rutter
  2. 2. Body & Bones <ul><li>He was about 40 feet long, about 15-20 feet tall, and about 5-7 tons in weight. </li></ul><ul><li>About a dozen T. rex skeletons have been found. Fossils are found in a variety of rock formations . </li></ul><ul><li>He had a massive skull balanced by a long, heavy tail. Forelimbs were small, though unusually powerful for their size, and bore two clawed digits. </li></ul><ul><li>T. rex probably had about 200 bones, about the same as humans have. </li></ul><ul><li>More than 30 specimens have been identified. Some are nearly complete skeletons. Soft tissue and proteins have been found on the bones. </li></ul>
  3. 3. When did he live? <ul><li>Tyrannosaurus was of the genus “ theropod dinosaur .“ </li></ul><ul><li>The species Tyrannosaurus “rex” (rex meaning 'king' in Latin) lived throughout what is now western North America. </li></ul><ul><li>T. rex lived during the late Cretaceous period , about 85 million to 65 million years ago -- toward the end of the Mesozoic Era . </li></ul><ul><li>This was known as the AGE OF REPTILES. </li></ul><ul><li>During this time, the Earth was seismically active, and there were many volcanic eruptions. The supercontinent Pangaea had broken up and the subcontinents were drifting apart. There were no polar ice caps, the sea level was higher than it is now, and the climate was warmer. </li></ul><ul><li>These creatures lived at the same time: Triceratops (which was probably preyed upon by T. rex), Ankylosaurus (an armored herbivore), Maiasaura (a plant-eater), Edmontonia (a plated dinosaur), Anatotitan (a duck-billed dinosaur), Pachycephalosaurus (a crested, plant-eating dinosaur), Parasaurolophus (a duck-billed dinosaur), Quetzalcoatlus (a huge flying reptile, not a dinosaur), Corythosaurus (a helmet-crested, duck-billed dinosaur), Styracosaurus , and many other fascinating creatures. </li></ul>
  4. 4. How big are his teeth? <ul><li>As big as a car? </li></ul><ul><li>As a house? </li></ul><ul><li>As a tree? </li></ul><ul><li>FIND OUT NOW >> </li></ul>
  5. 5. Answer <ul><li>T Rex was as big as a house. His head was gigantic in comparison to his body. His teeth were enormous. They were probably bigger than a baby. </li></ul>
  6. 6. Food: Predator or Scavenger? <ul><li>Tyrannosaurus was a bipedal carnivore . </li></ul><ul><li>Because he was a meat-eater and walked on two feet, it probably affected which foods he chose. </li></ul><ul><li>Tyrannosaurus rex may have been an apex predator , preying upon hadrosaurs and ceratopsians , although some experts have suggested it was primarily a scavenger . This question is still unsolved among paleontologists . </li></ul>
  7. 7. Was he smart? <ul><li>T. rex was a smart dinosaur. His brain was larger than most other dinosaurs. T. rex's brain was larger than the human brain, but the cerebrum (the part of the brain that we use for thinking) was tiny. </li></ul><ul><li>T. rex's brain was long and shaped like a tube. </li></ul><ul><li>Only very advanced dinosaurs and carnosaurs were probably smarter than T. rex. </li></ul>
  8. 8. Did he run or walk? <ul><li>T. rex walked on two legs. He was bipedal. </li></ul><ul><li>Its slim, pointed tail provided balance and quick turning while running. It held its tail erect, and did not drag it on the ground. </li></ul><ul><li>Because of the many fossils discovered in good condition, scientists are able to determine quite a bit about the creature’s biomechanics . </li></ul><ul><li>T. rex may or may not have been a fast runner. </li></ul><ul><li>It was among the last non- avian dinosaurs to exist. He was not related to today’s birds, and he did not have the capacity to fly. </li></ul><ul><li>Experts do not agree on the creature’s feeding habits, body shape, and potential speed when walking and running. </li></ul>
  9. 9. EXTINCTION Going, going, gone …
  10. 10. Too big for his own good? <ul><li>Cope's Rule says that creatures evolve to become more massive over time. </li></ul><ul><li>Although being bigger increases speed, intelligence and fitness, it means the species is more vulnerable to extinction. </li></ul>
  11. 11. Myths <ul><li>T. rex did not live during the Jurassic period , as many people think. Instead it lived millions of years later, during the late Cretaceous period , many millions of years ago. </li></ul><ul><li>T. rex was not the king of the dinosaurs (but its species name rex does mean king). Dinosaurs didn't have kings or any hierarchy in their species, like today’s mammals often do. </li></ul><ul><li>It was not necessarily green. No one knows what color it was. </li></ul><ul><li>T. rex was not mean. He was just an animal that ate other animals to survive. Reptiles do not have complicated emotions. </li></ul><ul><li>T. rex wasn't the biggest dinosaur. There were long-necked plant-eating dinosaurs that were bigger. Also, there were at least two other meat-eating dinosaurs that were bigger than T. rex. </li></ul><ul><li>T. rex did not eat cave people. The dinosaurs did not live at the same time that cave men did. Primitive people lived 63 million years (63,000,000 million) after T. rex went extinct. </li></ul><ul><li>T. rex was not the smartest dinosaur. But he was smart! </li></ul>
