“V” is for Viverravus
Another carnivore, Viverravus is rare in Paleocene faunas. We can tell it’s a carnivore due to the shape of its molars. Specifically, the first lower molar and the fourth upper premolar come together in a scissor-like configuration called the carnassial pair.
Viverravus has the blade-like lower molar characteristic of carnivores.
Viverravus is not known from The Breaks, but a related carnivore called Protictis is. I spent some time at the American Museum of Natural History studying specimens of Protictis and drawing sketches. Here’s one:
Carnivores are rare in any fossil collection. The fauna from The Breaks is no different with only four teeth out of 800 identified that are known to belong to carnivores.
