Biology: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.[1]
Description
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
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]
