The jurassic period jurassic period, second of three periods of the mesozoic era. extending from 201.3 million to 145 million years ago, it immediately followed the triassic period (251.9 million to 201.3 million years ago) and was succeeded by the cretaceous period (145 million to 66 million years ago). the morrison formation of the united states and the solnhofen limestone of germany, both. Dinosaur, (clade dinosauria), the common name given to a group of reptiles, often very large, that first appeared roughly 245 million years ago (near the beginning of the middle triassic epoch) and thrived worldwide for nearly 180 million years. most died out by the end of the cretaceous period, about 66 million years ago, but many lines of.

Dinosaurs gambol and charge through our imagination as scaly reptilian creatures with menacing teeth, claws, spikes, and hammering, bony bulbs. they roamed earth roughly 175 million years ago, and most were wiped out by an extinction event roughly 65 million years ago. thanks to ongoing scientific research, we continue to revise our theories about how dinosaurs evolved, what they ate, and how. Dinosaur extinction, fossils, evolution: dinosaurs lived in many kinds of terrestrial environments, and although some remains, such as footprints, indicate where dinosaurs actually lived, their bones tell us only where they died. the food preferences of herbivorous and flesh eating dinosaurs can be inferred to some extent from their general body plan and teeth.
