A giant mammal that lived 10,000 years ago in Brazil dug gigantic tunnels called “palaeoburrows”. And digging those tunnels required claws. Huge ones.

Despite its enormous claws, M. americanum was a vegetarian. This has been confirmed through chemical analysis of the animal’s teeth which shed light on what it ate during life. And it could have also meant that it was an easier target for – humans.

Yes, we do know they overlapped with humans in time as Megatherium fossils have been found with cut marks on them. This suggests that these giant sloths were on the menu thousands of years ago, which could have contributed to their extinction.
