Megatherium became extinct around 12,000 years ago as part of the end-Pleistocene extinction event, simultaneously with the majority of other large mammals in the Americas. The extinctions followed the first arrival of humans in the Americas , and one and potentially multiple kill sites where M. americanum was slaughtered and butchered is known ...
