Everything about Palaeospheniscus totally explained
Palaeospheniscus is an
extinct genus of
penguins which contains three
species at present. They are all (except
P. bergi, which is somewhat enigmatic) known from one or two handful of bones. All specimens were found in
Santa Cruz and
Chubut Provinces of
Patagonia,
Argentina. The fossils were recovered from the
Patagonian Molasse Formation, and are probably Early
Miocene to Late Miocene or possibly Early
Pliocene in age (Stucchi
et al. 2003).
Palaeospheniscus gracilis was long believed to be from the
Early Oligocene, but this is now thought to be erroneous.
P. gracilis and
P. wimani are often considered synonyms of
P. patagonicus. Recent researchers also tend to merge
Chubutodyptes into this genus as
P. biloculatus.
The species of
Palaeospheniscus were medium-sized to largish penguins, ranging from
P. gracilis with an estimated maximal length of 55 cm to
P. wimani, which reached up to 73 cm.
Palaeospheniscus is the namesake genus of the
subfamily Palaeospheniscinae, the Patagonian slender-footed penguins. These are apparently not closely related to the modern genus
Spheniscus.
