       With three pairs of short blunt horns on top its skull and two tusks that pointed down from the upper jaw,‭ ‬Eobasileus looked remarkably‭ ‬similar to its close relative Uintatherium‭ (‬which is why unsurprisingly it is a member of the Uintatheriidae‭)‬.‭ ‬With an upper size comparable to that of a large black rhinoceros‭ (‬Diceros bicornis‭)‬,‭ ‬Eobasileus was one of the largest animals in its habitat and when fully grown and probably did not have to worry too much about being attacked by the much smaller creodont predators of the time.
