Updated October 28, 2015. Following both the Precambrian Time and the Paleozoic Era on the Geologic Time Scale came the Mesozoic Era. The Mesozoic Era is sometimes called the age of the dinosaurs because dinosaurs were the dominant animals for much of the era. After the Permian Extinction wiped out over 95% of ocean dwelling species and 70% of land species, the new Mesozoic Era began about 250 million years ago.

Hadean Eon [4500 Myr - 4000 Myr ] The age of the Earth is projected to be about 4500 Myr from radiometric dating of the oldest rocks and meteorites. There is evidence of a time of intense bombardment of the Earth in the time period from about 4100 to 3800 Myr in what is called the late heavy bombardment.

Reptiles are tetrapod (four-limbed vertebrate) animals in the class Reptilia, comprising today's turtles, crocodilians, snakes, amphisbaenians, lizards, tuatara, and their extinct relatives. The study of these traditional reptile orders, historically combined with that of modern amphibians, is called herpetology.
