Bovidae gen. et sp. indet.

Fig. 3I.

Material: UPP MM-76, left m3, Mae Moh Basin, Northern Thailand; late middle Miocene (13.4–13.2 Ma), Nakhaem Formation, coal layer K.

Description and remarks.—UPP MM-76 (Fig. 3G) is heavily worn, making impossible to assign it to any particular genus. However, the specimen shares several morphological features, such as a selenodont tooth morphology and hypsodont crown, with Eotragus . While resembling E. lampangensis sp. nov. in the presence of a well-developed ectostylid and posterior ectostylid, UPP MM-76 differs from the other material described here in the extreme width of its anterior portion (transverse diameter of the anterior lobe measured at the base of the tooth crown) and in its poorly developed hypoconulid (Fig. 3G). Taken together, these features may indicate the existence of another bovid taxon in the Mae Moh Basin.
