Abstract

Portheus patagonicus Ameghino, 1901, described on the basis of an isolated tooth from the Leonian Stage (Upper Oligocene–Lower Miocene) of Patagonia, was interpreted as belonging to an ichthyodectiform fish. Recently, the holotype was relocated and an additional tooth was found. Comparison of both specimens and some additional information permit the identification of the teeth as belonging to a delphinoid cetacean of the family Kentriodontidae. This is the first report of this family in the southern Atlantic region.
