  2. Objectives • 1. After going through the PowerPoint on dinosaurs, students will be able to decide (write) if they want dinosaurs to still exist and explain why or why not with 100 percent accuracy. • 2. Forming an individual book on dinosaurs after the lesson, students will be able to describe (write) and draw pictures of a specific type of dinosaur with 100 percent accuracy • 3. As a class, students will fill out a vendiagram distinguishing the difference between 3-D models of dinosaurs and the dinosaurs they learned about from the PowerPoint with 100 percent accuracy.

  4. Overview • Group of reptiles: over 700 species • Alive over 160 million years ago ( Mesozoic Era) • - Triassic Period ( 250-200 million years ago) • - Jurassic Period ( 200-145 million years ago) • - Cretaceous Period ( 145-65 million years ago) • Faster than present reptiles • Descendants are birds Slide Menu

  5. Interactive Fossil Dig Slide Menu

  6. Why do they not exist today? • Popular Theory: Alvarez Hypothesis • Caused by an Asteroid • - 65 million years ago • Force of 100,000 billion tons of TNT • “ Impact Winter” • High Carbon Dioxide levels Died from lack of food and heat Slide Menu

  7. Herbivores • Plant-eaters : leaves, twigs, and seeds • Stones? • Swallowed to ground food in stomach • Broad, flat teeth • worn down from grinding food • Low jointed jaws • Most dinosaurs Slide Menu

  8. Carnivores • Meat eaters: dinosaurs, lizards, insects, and mammals • Long, Sharp, and Curved Teeth • - made to tear through meat • Teeth did not precisely meet Slide Menu

  9. The Largest Dinosaur • Argentinosaurus • - “ Sliver Lizard” • 120 feet long; 70 feet tall • Herbivore • Weighed 90-110 tons • - heaviest land animal ever lived • Could reach 115-150 feet Slide Menu

  10. Longest Dinosaur • Seismosaurs [ Size-moe-Sore-us] • - “ Earth-shaking lizard” • 110 feet long • - longer than a blue whale ( 100 ft.) • Herbivore • Front legs shorter than back legs • Weighed a 100 tons Slide Menu

  11. Fiercest Dinosaur • Not the Tyrannosaurus Rex • Utahraptor • - discovered in Utah • 6.5 meters long, 2 meters high • Weighed little over a ton • Carnivore • Hooked, slashing claw on each foot Slide Menu

  12. Fastest dinosaur • Dromiceiomimus [ dro-MEE-see-o-MYE-mus] • - “ Emu Mimic” • Run up to 60 km per hour • 11-19 feet long, 6-10 feet tall • Weighed 220-1000 lbs. • Herbivore and Carnivore • Long, slender legs with three toes Slide Menu

  13. Tallest Dinosaur • Brachiosaurus • - meaning ‘arm’ and ‘lizard’ in Greek • 85 feet tall • Weighed 30-45 metric tons • Herbivore • - Ate between 440-880 pounds a day • Extremely long necks Slide Menu

  14. Smallest Dinosaur • Lesothosaurus [ leh-SO-tho-Saw-rus] • - “ diagnostic Lesotho lizard” • 3 feet long, 1 foot tall • Weighed 15 lbs. • - would be size of a chicken • Herbivore • Small and speedy Slide Menu

  16. Summary • Dinosaurs lived about 160 million years ago. • There have been over 700 different species identified. • There is not one for sure theory of how they died out, but the most accepted theory is due to an Asteroid. • The two main groups of dinosaurs were herbivores and carnivores. • The largest Dinosaur was the Agrentinosaurus weighing in at 110 tons. Slide Menu

  17. Summary Part 2 • The Longest Dinosaur was the Seismosaurus at 40 meters long. • The Fiercest Dinosaur was the Utahraptor equipped with a slashing claw on each foot. • The fastest dinosaur was the Dromiceimimus who could run up to 60 km a hour. • The tallest dinosaur, the Brachiosarus, was 85 feet talland ate 440-880 pounds of plants a day. • The smallest dinosaur was the Lesothsaurus , which would be the size of a chicken, with a height of 1 foot and a weight of 15 pounds.
