Palaeospheniscus bergi

Palaeospheniscus bergi is a species of the extinct penguin genus Palaeospheniscus. It stood about 60 to 75 cm high in life, or somewhat smaller on average than the extant African penguin.

Etymology
The species is named for Carlos Berg, a member of the La Plata Museum of Natural Sciences staff at the time when Moreno worked there.

Description
Many bones referrable to this species have been recovered from the Early to Middle Miocene Gaiman and Puerto Madryn Formations and the El Foyel Group. Known localities are Trelew in Chubut Province and Puerto San Julián in Santa Cruz Province, Argentina.

Some recent researchers have considered Palaeospheniscus gracilis to be a synonym for this species.

Taxonomy
Bones of this species were described as no less than 6 "species" (including the correct one) from 3 "genera" by Florentino Ameghino in a single publication. The synonyms are as follows: Either Pseudospheniscus interplanus or P. planus, as well as either Pseudospheniscus concavus or P. convexus, are a lapsus too.
