1. Dinosaurs Ms. Palumbo�s 3rd Grade Science Class

2. What are the different time periods that dinosaurs lived in? The Triassic Period 144 to 65 Million Years Ago The Jurassic Period 206 to 144 Million Years Ago The Cretaceous Period 144 to 65 Million Years Ago

3. The Triassic period was named in 1834 by the German geologist Friedrich August Von Alberti This is the first stage of the Mesozoic era which is referred to as the age of the dinosaurs. This period took place 248-208 million years ago. Pterosaurs or flying reptiles made their first appearance here as well as frogs, turtles, and crocodiles. During the Late Triassic period, many small mammals also arose.

5. In the Jurassic period the Age of the Ruling Reptiles began. During this period, vegetation was greener and more lush. The Jurassic Period was broken up into several sections as the chart to your left shows. By Late Jurassic, huge dinosaurs such as Stegosaurus, Ceratosaurus, Brachiosaurus, and Allosaurus walked the lands. Flying reptiles ruled the skies and the earliest known birds also appeared.

6. Name Means: Arm Lizard Weight: 33-88 tons Height: 85 feet Was one of the tallest and longest dinosaurs found. It had a long neck, small head, and relatively short, thick tail. Brachiosaurus walked on four legs and unlike most dinosaurs unusual front legs together with its very long neck gave Brachiosaurus a giraffe-like stance and great height. was an herbivore, a plant eater Lived during the Jurassic period

7. Length: 80 feet Weight: 33 tons Giant plant eating dinosaur Walked on four thick legs Janenschia and some of the other large long-necked plant-eaters needed to have large, powerful hearts and very high blood pressure in order to pump blood up the long neck to the head and brain. Lived during the late Jurassic period, about 156 million to 150 million years ago.

8. The Cretaceous period may have seen more dinosaurs then ever before. Horned Cretaceous dinosaurs appeared, like the Triceratops and Centrosaurus. The armored Ankylosaurus, duckbilled Parasaurolophus, and large carnivore Tyrannosaurus were a few of the quickly evolving dinosaurs. Birds became increasingly numerous and flowering plants were emerging. By the end of the Cretaceous period, all large and small ruling reptiles, except the crocodile went extinct. This period is usually noted for being the last portion of the "Age of Dinosaurs
