This paper discusses the Jurassic period of 206 to 144 million years ago and focuses on the Jurassic dinosaurs of the United States. It discusses the fossils that have been found and what they suggest about the creatures that existed then. The paper describes some of the types of dinosaurs that have been discovered and their characteristics as far as can be conjectured.
From the Paper:"It is important to note that we actually have no proof whatsoever how any dinosaur behaved. It is all conjecture and educated guess based on how modern day reptiles behave, and what the fossils tell us about their anatomy. For example we know that the velociraptors and allosaurs had sharp claws on their feet. This indicates that they used them as offensive weapons to dispatch larger prey animals (Anonymous, N.D.)"
"They ranged over North America and ruled wherever they chose to be. There was no animal on the planet safe from them. T rex means tyrant lizard king. He is well named."
