“…jiulongkouensis an adult cranium with very small supraorbital protuberances and a strong sagittal crest, as in Amphimoschus. It is conceivable that these forms gave rise to proto-Eotragus forms ("Eotragus" noyei, "Eotragus" minus, and Namacerus), whose horncores are larger but remain smaller than in European primitive Eotragus, reported from the Spanish sites of Buñol, Córcoles, and Tarazona (Alférez 1981;Moyá-Solá 1983;Astibia 1987;Mazo et al 1998). Further increase in size led to Eotragus clavatus, well-known from Sansan .…”

We describe here the Bovidae from the early Middle Miocene site of Maboko, Kenya, known for its rich and highly diverse assemblage of Primates. They are attributed to two taxa of slightly different sizes, Turcocerus africanus n.sp. and Kubanotragus pickfordi. In addition to Kenya, Turcocerus ranges through the Middle Miocene from Turkey to China; it might have originated in Africa but the lack of precise dating weakens any phylogeographic hypothesis.Kubanotragus has similar chronological and geographic ranges. Both Maboko species retain primitively low levels of hypsodonty compared to their northern relatives and may have been less specialized for grazing than Eurasian taxa. The Maboko Bovidae illustrate an early diversification of the family in Africa that appears to pre-date the major diversification of Bovidae and appearance of the diverse clades that are characteristic of modern African pecoran faunas.

We describe the first bovid fossils from the late middle of the Mae Moh Basin of Northern Thailand, and assign the material to the new species Eotragus lampangensis sp. nov., Eotragus cf. lampangensis, and an indeterminate bovid. Our material represents the first report of Eotragus from Southeast Asia, thus greatly extending the geographic distribution of this genus across the Old World continents. While comparisons of the Southeast Asian specimens with abundant material of E. clavatus from Sansan (France) and E. aff. clavatus from Tarazona de Aragón (Spain) indicate a high degree of intraspecific variation within single species of Eotragus , the existence of two distinct taxa at Mae Moh remains a possibility. Based on previous carbon isotope studies of Mae Moh herbivore tooth enamel, Eotragus lampangensis sp. nov. foraged predominantly in an ecotone between grassland and forest.
