Dinosaurs were a long lasting branch of the Archosaur family exisiting between 230 million years ago to 65 million years ago. they had many different familys and most dinosaurs depended on other dinosaur species for protection, food (For both Carnivores and Herbivores) and sometimes shelter for pterosaurs and some little dinosaurs living in the debris left by Sauropods. they went extinct 65 million years ago for reasons in dispute but the most widley accepted theory is that an asteroid smashed into earth off the coast of present day mexico causing an eco-system collapse causeing all land creatures except crocodiles above 15 pounds to die off. the theory is that when the asteroid hit the dust blocked out the sun, and forest everywhere set ablaze. there must have been massive earthquackes and Tsunamis all over the earth, and without the sun plants possibly died out, causing in turn herbivores to die out, wich finnaly caused the Carnivorous Dinosaurs to die out.
