Rhinocerotid fossils from the lower upper Miocene Namurungule and Nakali Formations, northern Kenya, are described. These materials reveal the following diagnostic characters of Chilotheridium pattersoni: a strongly constricted protocone with a flattened lingual wall, a hypocone groove, a developed crochet, and an antecrochet curved toward the entrance of the medisinus. Specimens previously described from the Namurungule Formation as rhinocerotids are re-identified as C. pattersoni. The Nakali Formation specimens presented in this study are the first discovery of C. pattersoni from this locality. In addition, deciduous teeth of C. pattersoni, which were unknown previously, are reported for the first time. This discovery of C. pattersoni extends its temporal range to the early late Miocene.
