Dinosaurs are a group of reptiles that dominated the land for over 140 million years (more than 160 million years in some parts of the world). they evolved diverse shapes and sizes, from the fearsome giant spinosaurus to the chicken sized microraptor, and were able to survive in a variety of ecosystems. one of the reasons for dinosaurs' success.
