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.[1]
Description
[edit]Prodinoceras was rather large, reaching 2.9 m (9 ft 6 in) in length.[2] 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. The genus also bears 3 upper incisors, a trait lacking in later dinocerates. The astragalus also possesses a distinct neck and the trochlear facet is not expanded.[3]
Classification
[edit]Prodinoceras possesses traits that indicate it is a sister group to the other derived dinocerates.[4] Most literature posits Prodinoceras and Probathyopsis as close relatives.[1][3]
