The rhinocerotid remains from Cerro de los Batallones (Madrid, Spain) are described in this paper. Their preliminary ascription to Aceratherium incisivum Kaup is confirmed. Most of the remains belong to an individual, and the comparative study shows that it has the mandibular symphysys relatively longer and the height of the vertical ramus somewhat shorter than other populations of the species; in addition, the scaphoid presents three lateral facets for the semilunar, what is uncommon in Aceratherium and closer genera. Dimensions are in general lesser than those of the type material from Eppelsheim (Germany), but they fall into the range established for the species from different European localities. Cerro de los Batallones is considered to be late Vallesian (late Miocene) in age. A. incisivum is well represented in Europe during the Vallesian and Turolian, although it has been scarcely recorded in Spain, except in the Valles-Penedes basin. This new material enlarges the knowledge of this species in the central basins of Spain.
