Cast of the specimen AMNH3338 of Paraptenodytes antarcticus, of the Museo Paleontologico Egidio Feruglio in Trelew, Argentina.

Paraptenodytes is an extinct genus of penguins which contains two or three species sized between a Magellanic Penguin and a small Emperor Penguin (P. antarcticus). They are known from fossil bones ranging from a partial skeleton and some additional material in the case of P. antarcticus, and a single humerus in the case of P. brodkorbi. The latter species is therefore often considered invalid; a recent study considers it indeed valid, but distinct enough not to belong into Paraptenodytes. The fossils were found in the Santa Cruz and Chubut Provinces of Patagonia, Argentina, in Patagonian Molasse Formation rocks of Early Miocene age; later occurrences are apparently from Late Miocene or possibly even Early Pliocene deposits.
