Anthropornis is agenus ofgiant penguin that lived 45-33 million years ago, during theLate Eocene and the earliest part of theOligocene.[1]

Description

[edit]
Life restoration ofA. grandis

Anthropornis reached 1.8 m (5 ft 11 in) in length from the tip of the beak to the tip of the tail, and 90 kg (200 lb) in weight. There is also an estimate that one remain ofAnthropornis can reach that body length of 2.05 m (6 ft 9 in) and 108 kg (238 lb) in weight.[2] Fossils of it have been found in theLa Meseta Formation onSeymour Island off the coast ofAntarctica and inNew Zealand. By comparison, the largest modern penguin species, theemperor penguin, is just 1.2 m (3 ft 11 in) long.

The type species,Anthropornis nordenskjoldi, had a bent joint in the wing, probably avestigial trait from its flying ancestors.
