Prodinoceras Mongolotherium (Prodinoceras Matthew, Granger & Simpson, 1929)
Dimensions: length - 2,9 m, height - 120 сm, weight - 400 kg
Temporal range: late Paleocene of Mongolia
Typical representative: Mongolotherium Flerov, 1952
Prodinoceras was the earliest known uintathere genus, which lived in the late Paleocene of Mongolia. It was a relatively small uintathere, reaching 2.9 m in length. It is also regarded as the basal uintathere, as, although it had the characteristic fang-like tusks, it had yet to evolve the characteristic knob-like horns. It is very similar to its North American counterpart, Probathyopsis. All experts regard it as Prodinoceras' sister genus.
