Cormohipparion
Encyclopedia
The extinct Cormohipparion was originally described as a new genus of horse, and assigned to the tribe
Hipparionini. However it was soon argued that the partial material fell within the range of morphological variation seen in Hipparion
, and that the members of Cormohipparion belonged instead within Hipparion. This rested on claims that pre-orbital morphology did not have any taxonomic significance, a claim that detailed study of quarry sections later showed to be false. A reappraisal of many horse genera was thus conducted in 1984, and the proposed synonymy was not acknowledged by later literature.
The genus is considered to represent an ancestor to Hippotherium. Its fossils have been recovered from as far south as Mexico.
Tribe (biology)
In biology, a tribe is a taxonomic rank between family and genus. It is sometimes subdivided into subtribes.Some examples include the tribes: Canini, Acalypheae, Hominini, Bombini, and Antidesmeae.-See also:* Biological classification* Rank...
