Redescription and phylogenetic position of the Early Miocene penguin Paraptenodytes antarcticus from Patagonia. American Museum Novitates 3525
Paraptenodytes antarcticus is one of the best-known and most complete fossil penguins. This taxon is so distinctive that it has traditionally been classified in its own subfamily (Sphenisciformes: Paraptenodytinae) separate from all living penguins (Spheniscinae). The well-preserved partial skull of...
