Everything about Archaeospheniscus totally explained
Archaeospheniscus is an
extinct genus of large
penguins. It currently contains three
species, known from somewhat fragmentary remains.
A. wimani, the smallest species (about the size of a
Gentoo Penguin), was found in Middle or Late
Eocene strata (34-50
MYA) of the
La Meseta Formation on
Seymour Island,
Antarctica, whereas the other two, about the size of a modern
Emperor Penguin, are known from bones recovered from the Late
Oligocene Kokoamu Greensand Formation (27-28
MYA) at
Duntroon, New Zealand.
The genus is one of the earliest known primitive penguins. Its
humerus is still very slender, between the form seen in ordinary bird wings and the thickened condition found in modern penguins. On the other hand, the
tarsometatarsus shows a peculiar mix of characters found in modern and primitive forms. Whether this signifies that the genus is an ancestor of modern taxa or represents a case of
parallel evolution is unknown.
