Namibiocyon is an extinct genus of carnivoran mammals, belonging to the family Amphicyonidae (“bear dogs”), that lived in Namibia during the Early Miocene epoch.

[5] Although larger than a wolf,[11] Namibiocyon was a medium-sized amphicyonid, bigger than species such as Ysengrinia gerandiana and Cynelos lemanensis,[5] but slightly smaller than Afrocyon[8] and C. anubisi[9] (which is sometimes moved into a separate genus, Mogharacyon).

[8] Namibiocyon possesses an extensive mandibular symphysis, which has a rugose surface, and a high horizontal ramus.

It is slightly concave in lateral view, and here is a marked area for the musculus quadratus plantae, reaching almost to the tuber calcis, in its central zone.

As in other amphicyonids, the talar facet of the coracoid process, whereas the medio-laterally elongated sustentaculum tali is less distally displaced than in Amphicyon major, and its posterior groove has more marked borders.

Whereas the articular facet for the cuboid of A. major is elliptical and slightly concave in distal view, that of Namibiocyon is semicircular.

[6] Namibiocyon ginsburgi was originally classified as a species of Ysengrinia, a taxon with similar hypercarnivorous adaptions now referred to the subfamily Thaumastocyoninae.

[1] Its strongly pronounced hypercarnivorous features have led some researchers to suggest that it was ancestral to the genus Myacyon, which was widespread throughout Africa in the middle to late Miocene.

[16] In comparison to other predators of this ecosystem, Namibiocyon was of intermediate size, considerably smaller than its larger relative Amphicyon and the giant hyaenodont Hyainailourus, but larger than the felids Diamantofelis and Namafelis, the viverrid Orangictis, the stenoplesicitid Africanictis, the large mustelid Namibictis and the hyainailourid Buhakia.

[11][17] Therefore, it likely preyed on medium-sized mammals,[5] such as the suids Namachoerus and Nguruwe,[18] the tragulid Dorcatherium,[19] the small bovid Namacerus, or juveniles of the climatoceratid Orangemeryx.

[20] Other inhabitants include the macroscelidid Myohyrax, the springhare Megapedetes, the lagomorph Australagomys the diminutive aardvark Myorycteropus[21][22] and the proboscidea Afromastodon and Prodeinotherium.
