What is "perudyptes"

Perudyptes is a basal penguin from the middle Eocene Paracas Formation of Peru.

Perudyptes devriesi is a basal penguin from the middle Eocene (~42 Ma) Paracas Formation of Peru. This new discovery is able to fill a major phylogenetic and stratigraphic (~20 million year) gap between the earliest fossil penguins ( Waimanu manneringi and Waimanu tuatahi, ~58–61.6 Ma) and the next oldest partial skeletons.

The skull of Perudyptes is characterized by deep temporal fossae and an elongate, narrow beak that differs from other reported stem penguins in its short mandibular symphysis. The wing skeleton of Perudyptes preserves a combination of plesiomorphic features also observed in the basal penguin Waimanu and derived features shared with more crownward penguins.
