Megatherium - The Stagger

i came across yet another paper where one of the two authors is the same guy, richard ferena. They argue that the anatomy of the forearms such that this is an animal that would have been using vicious attacks with its claws. And theyr like, well, what if this means it was like turning animals over toget at the soft under bellyno? Thisis possibly out there. But i like the idea that ferena has as made a career, at least partially on on proposing alternate interpretations of the megatherium. I'm not sure entirely if we're talking about a a living gliptidant or a dead one.
