Other notable traits include the presence of a postorbital bar, the presence of a ventrally extended mental process (bony extensions on either side of the lower jaw), and the shortening of the skull behind the orbits. It had a very robust constitution, with B. morrisi intermediate between the size of Sansanosmilus and B. fricki, which is thought to have been a particularly large predator and the largest of all barbourofelids.

It had an exceptionally sturdy build, with B. morrisi falling between the size of Sansanosmilus and B. fricki, which is believed to have been a particularly massive predator and the largest of all barbourofelids.
