Paleo Profile: Pakistan’s Butterfly-Faced Beast

In any list of weird fossil mammals, the regular set of ancient beasts are trotted out. There’s always a brontothere. Uintatherium often shows up. Deinotherium isn’t a surprise, either.

Exactly what sort of beast Prolibytherium was, no one knows for sure. The herbivore has been punted around the hoofed mammal tree a bit, and, for the moment, it seems closest to a group of extinct, deer-like mammals called climacoceratids. But one thing is for sure – this mammal wore some very bizarre headgear.
