Miocene Patagonian penguins: craniomandibular morphology and functional mechanics
Fossil penguins (Aves, Spheniscidae) are widely recorded throughout the Southern Hemisphere and are especially well represented from the Eocene to present in Patagonia. There are currently three Miocene specimens that include preservation of part of the skull and mandibles: Paraptenodytes antarcticu...
