The story of dinosaurs begins in the Triassic period, around 230 million years ago. During this time, the supercontinent Pangaea was still intact, and the climate was generally hot and dry. Early dinosaurs evolved from a group of reptiles known as archosaurs, which also gave rise to modern birds and crocodiles. The earliest known dinosaurs, such as Eoraptor and Herrerasaurus, were small, bipedal predators that lived in what is now South America.

These early dinosaurs were part of a diverse ecosystem that included various other reptiles, amphibians, and the first true mammals. Over time, dinosaurs began to diversify and dominate these ecosystems, outcompeting many other groups of animals. This period laid the foundation for the incredible diversity and adaptation that would characterize the dinosaur lineage.
