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.
The period after the Triassic is the Jurassic.
Triassic
After the Triassic period, the Jurassic period began, followed by the Cretaceous.
