The earliest period that dinosaurs existed was the Triassic period, some 225 million years ago. These were not the huge dinosaurs of the later period. Most dinosaurs of that age were small creatures that ate meat and walked on hind legs. Shaaron
Yes, the first dinosaurs evolved in the Triassic period. The earliest dinosaurs that have been discovered are Eoraptor and Herrerasaurus, which lived 231.4 million years ago.
Dinosaurs evolved 225 million years ago in the Late Triassic.
Although both crocodiles and dinosaurs are Archosaurs. Crocodilae are not dinosaurs. The only living relatives of dinosaurs are the birds. The Crocodilae evolved from the anchient Crurotasi reptiles which 1st appeared in the Early Triassic. This lineage would evolve into true crocodilae around 200 million years ago at the very end of the triassic period. The lineage that lead to dinosaurs was Ornithodira which broke away other Archosaurs around the Mid Triassic. These were later to evolve into dinosaurs in the late triassic some 230 million years ago.
