Dinosaurs were reptiles that lived during the Mesozoic Era. The
earliest-known dinosaurs appeared about 230 million years ago. The
last of the dinosaurs went extinct 65 million years ago.
The first dinosaurs were only about 6 feet long. In the next 165
million years, dinosaurs evolved into many different shapes and
sizes. The smallest dinosaurs were just the size of a chicken, and
the largest were as big as a house.
Some
dinosaurs, like T. rex, were meat-eaters (also called carnivores),
but most dinosaurs were plant-eaters (also called herbivores).
It is thought that dinosaurs went extinct after a huge asteroid hit
the Earth. This event changed the world's climate. Those animals and
plants that couldn't adapt (including the remaining dinosaurs) went
extinct.
