Palaeospheniscus bergi is a species of the extinct penguin genus Palaeospheniscus.[1] It stood about 60 to 75 centimetres (24 to 30 in) high in life, or somewhat smaller on average than the extant African penguin.

Etymology

[edit]

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

[edit]

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.[1] 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.[2]

Taxonomy

[edit]

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:

  • Palaeospheniscus bergii (lapsus) Ameghino, 1891
  • Paraspheniscus bergi Ameghino, 1905
  • Palaeospheniscus planus Ameghino, 1905
  • Palaeospheniscus rothi Ameghino, 1905
  • Pseudospheniscus interplanus Ameghino, 1905
  • Pseudospheniscus planus Ameghino, 1905
  • Pseudospheniscus concavus Ameghino, 1905
  • Pseudospheniscus convexus Ameghino, 1905

Either Pseudospheniscus interplanus or P. planus, as well as either Pseudospheniscus concavus or P. convexus, are a lapsus too.
