Hemibos


Hemibos is an extinct even-toed ungulate belonging to the family Bovidae. Its fossil remains were found in Asia and Europe.

Description

This animal was a large bovid similar to the modern Asian buffalo, of which it is probably ancestral. It was characterized by elongated and non-prominent frontal bones; the bone cores of the horns did not have a neck at the base, and the angle between the horns was variable but usually between 85 ° and 110 °. Also, the orientation of the horns was variable according to the species: the species H. triquetricornis, H. acuticornis and H. galerianus possessed horns directed backwards, outwards and slightly upwards, while H. antelopinus and H. palaestinus possessed different morphologies. The teeth were hypsodont, with increasing development of dental cement; the upper molars were square.

Classification

The genus Hemibos was first described in 1865 by Rütimeyer, based on fossils found in India in plio-Pleistocene soils. The genus includes five species; three of these come from the Pinjor formation of the Siwaliks, one is known from Gansu in the lower Pleistocene, and another is the largest and most recent and comes from Ponte Galeria and Ponte Milvio and dates from the lower Pleistocene/middle Pleistocene boundary. In lower Pleistocene Spain, a form similar to H. gracilis was found. Another species attributed to Hemibos is H. palaestinicus, from Israel, but the dating is not certain and a morphological analysis indicates it may belong to the genus Bison. The species Probubalus occipitalis is considered identical to H. triquetricornis.
