How dinosaurs ruled
Dinosaurs evolved throughout all three Mesozoic periods. Dinosaurs started in the Triassic period and evolved bigger. At the Triassic period. There were mostly small and skinny dinosaurs. The world was taken over by archosaurs and crocodilians so dinosaurs didn't have the chance to take over. At the Triassic mass extinction, which killed many of the archosaurs, dinosaurs finally had the chance to take over. |
