The genus Pygoscelis ("rump-legged") contains three living species of penguins collectively known as "the brush-tailed penguins".[citation needed]
Taxonomy
Mitochondrial and nuclear DNA evidence suggests the genus split from other penguins around 38 million years ago, about 2 million years after the ancestors of the genus Aptenodytes. In turn, the Adelie penguins split off from the other members of the genus around 19 million years ago.[1]
The three extant species are:
- Adélie penguin, Pygoscelis adeliae
- Chinstrap penguin, Pygoscelis antarctica
- Gentoo penguin, Pygoscelis papua
Extinct species:
- Pygoscelis grandis (Bahía Inglesa Formation, Late Miocene/Early Pliocene of Bahía Inglesa, Chile)
- Pygoscelis calderensis (Bahía Inglesa Formation, Late Miocene of Bahía Inglesa, Chile)
- Pygoscelis tyreei (Pliocene of New Zealand)
The latter two are tentatively assigned to this genus.
