The earliest reptiles known evolved around 312 million years ago, and looked a lot like lizards. However, they were not actually lizards. The oldest known lizard fossil dates to 220 million years ago, about the same time that dinosaurs evolved. That was during the Triassic period of the Mesozoic era.

with the first dinosaurs.

None-avian dinosaurs first appeared in the Triassic period and were the dominant land vertebrates through the Jurassic and Cretaceous periods. At the end of the Cretaceous period, 65.5 million years ago, all non-avian dinosaurs went extinct. Birds, which are now classified as dinosaurs, continue to live to his day.
