Prodinoceras

Prodinoceras, from Ancient Greek πρό (pró), meaning "before", δεινός (deinós), meaning "terrible", and κέρας (kéras), meaning "horn", is the earliest known dinocerate genus, which lived in the late Paleocene of Mongolia. It was a relatively small uintathere, reaching 2.9 m (9 ft 6 in) in length.^[1] It is also regarded as the most basal uintathere, as, although it had the characteristic fang-like tusks, it had yet to evolve the characteristic knob-like horns.
