Trogosus

Trogosus is an extinct genus of tillodont mammal. Fossils have been found in Wyoming and British Columbia,[2] and date from the Eocene between 54.8 and 33.7 million years ago. Trogosus was a bear-like herbivore with a large, short skull and flat feet, and had a skull 35 cm (14 in) long with an estimated body weight of 150 kg (330 lb).[3] It had large, rodent-like incisors, which continued growing throughout the creature's life. Judging from the heavily worn molar teeth, Trogosus fed on rough plant material, such as roots and tubers.[4]
