Crocodiles have been on Earth for over 200 million years, making them one of the oldest living reptile species. They have survived multiple extinction events, adapting to various environments and evolving into the animals we see today.
200 million years
The Mesosaurus lived in Antarctica back 100 million to 200 million years ago : )
Dinasaurs was living on earth about 100 million and 50 million years. They have been on the earth from 200 million and 20 million years ago, and die out at about 65 million years ago at the end of Upper Cretaceous.
200 million years ago, the Earth was known as Pangaea, a supercontinent that existed during the late Paleozoic and early Mesozoic eras. This landmass eventually broke apart to form the continents we recognize today.
During the Jurassic period - approximately 200 million to 145 million years ago.
No. Sauropods first appeared a little over 200 million years ago and died out about 65 million years ago.
The cicada has been on the earth for more than 200 million years. Cicada's have been on earth probably as long as cockroaches, which is over 250 million years.
dinosaurs
Heterodontosaurus lived in the Early Jurassic period, around 200-190 million years ago.
A fabrosaurs were small dinosaurs that lived towards the beginning of the Jurassic Period, about 208-200 million years ago.
200-250 million years ago it broke away (like everything else) as the earth expanded..
