Trogosus was a
bear-like herbivore with a large, short
skull and flat feet, and had a skull long with an estimated body weight of . 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.
Trogosus possessed an exposed
midbrain, a small
neocortex, an orbitotemporal canal ventral to rhinal fissure, large olfactory bulbs, and a broad circular fissure. Its tiny neocortex relative to contemporary carnivorans and artiodactyls may have disadvantaged it when escaping predation by the former and competing for resources with the latter. ==Notes==
