The study of dinosaur fossil organisms

lovethee History

“Lions and tigers and bears” and the fantasy animals of Oz and science fiction are fun, but, as a paleontologist, I prefer the stranger than fiction animals of the past. Paleontology, the study of fossil organisms, is, to me, a form of time travel. Dinosaur bones and the sediments they are preserved in are relics of past events.

Predatory dinosaurs lived from about 235 to 65 million years ago-grve or take a million here and there-during the Mesozoic Era (see the time chart on pages 224-225). The Mesozoic is split into the three periods. About halfivay through the first period of the Era-the Triassic, which lasted from 248 to 213 million years before the present @,,{YBP)-the first dinosaurs showed up, and they had to get along with a number of nondinosaurian predators. By the second period, the Jurassic, predatory dinosaurs had become the sole big killers. The same was true through the third, the Cretaceous Period (144-65IvIYBP), which also saw the first flourishing of birds.walking dinosaur costume Dinosaurs were extinguished at the end of the Mesozoic Era, and the following erathe Cenozorc-was the age of mammals. Compared to the briefness of our civilization, the span of predatory dinosaur existence appears vast. But dinosaurs are recent and short-lived compared to the Earth itself, which is celebrating its 4.5 billionth or so birthdav. the study of fossil organisms.
