The American Museum of Natural History recently conducted new research on an extinct weasel relative called Leptarctus primus. The Leptarctus primus has always intrigued researchers because of its unusually-shaped head, which has led to conflicting theories about its diet and feeding activity. The new study of its oddly-shaped skull finds that it is most similar to an American Badger, and shows that it was likely a carnivorous predator. The team compared a fossil skull with 18 species of modern carnivorans using CT scans of the skulls and virtual modeling of feeding mechanisms.
