They weigh more than a ton.
In South America, scientists discovered the remains of the tortoise Stupendemys geographicus, who lived in the region 5-10 million years ago, reports CNN.
This is one of the largest, if not the largest tortoise that has ever existed.

Fossils three meters long and weighing about a ton were found in Venezuela and Colombia. According to the BBC, Stupendemys geographicus was discovered back in the 1970s, but scientists still do not know much about this species.
It is believed that turtles lived at the bottom of lakes and rivers, ate small animals, fruits and seeds. Scientists suggest that the closest relative of this species is the large-headed, side-necked Amazon turtle, which is one hundred times smaller than Stupendemys geographicus.
The discovered remains will allow to better study the lifestyle of the turtles that lived on the planet several million years ago, and to learn more about the process of their evolution.
