The Mesozoic period is part of the geologic system of classifying geologic formations.
Under the uniformitarian dates assigned by secular geologists, it represents approximately the period of Earth's history from 251 million years ago to 65 million years ago.[1] Under this timetable, it is most famous for being the era of the dinosaurs.
The Mesozoic is divided into three periods, the Triassic, the Jurassic, and the Cretaceous.
Flood geologists reject the uniformitarian assumptions behind the dates derived by secular geologists, so they reject these dates (see geologic system).
