Colossochelys atlas- formerly known as Testudo atlas, and originally described as Geochelone atlas- is an extinct species of cryptodire turtle from the Pleistocene period, about 2 million years ago. During the dry glacial periods it ranged from western India and Pakistan (possibly even as far west as southern and eastern Europe) as far east as Sulawesi and Timor in Indonesia.

Colossochelys atlas was the biggest tortoise of all time. It has a juvenile stage. Babies and juveniles will move in herds. Additionally, it has fossils for you to dig up and clone it at the Extinct Research Lab!
