Dinosaur Foot Steps

Dinosaurs were group of mainly large, land-living reptiles. Like reptiles today, most of them had scaly (although some had feathers), a long tail, teeth and claws on the fingers and toes. But while modem reptiles walk their legs-sprawled sideways, dinosaurs walked upright with their legs directly below them, as mammals do. This main feature made them swift and agile on land. Dinosaurs were among the most amazing and successful animals ever. From ancestors which were no bigger than dogs, they evolved into gigantic killers as elephants. They were plant-eaters with lengths of several bus and nimble on little creatures the size of chickens. While they ruled the land, no mammal larger than domestic cat survived. Dinosaurs first appeared about 230 million years ago and flourished for an astonishing 165 million years. Then, 65 million years ago, they suddenly and mysteriously disappeared. By comparison; modern humans have inhabited the earth for only about 100,000 years.
