Abstract

Recently collected portions of the left and right mandibular rami of the extinct Palaeoctodon aff. P. simplicidens are analyzed. These remains are from the Huayquerian (late Miocene) Cerro Azul Formation, that outcrops in Bajo Giuliani, La Pampa Province, Argentina. We concluded that the following features, among others, indicate that Palaeoctodon represents the oldest Ctenornyine-like Octodonúdae: the major axis of the masticatory plane directed antero-posteriorly, and a very reduced third molar.
