Extinct penguins

Anthropornis is a genus of giant penguin that lived 45-33 million years ago, during the Late Eocene and the earliest part of the Oligocene.

Icadyptes is an extinct genus of giant penguins from the Late Eocene tropics of South America.

Waimanu is a genus of early penguin which lived during the Paleocene, soon after the Cretaceous–Paleogene extinction event, around 62–60 million years ago. It was about the size of an emperor penguin (1 metre (3.3 ft)). It is one of the most important bird fossils for understanding the origin and evolution of birds because of the time period it comes from, and the position of penguins near the base of the bird family tree. alt=Artist's reconstruction of fossil penguin Waimanu manneringi|thumb|Artist's reconstruction Waimanu was a very early member of the Sphenisciformes, the order that include

Kairuku is an extinct genus of penguin. It contains three species, K. grebneffi, K. waitaki and K. waewaeroa. This taxon is known from bones from 27 MYA (late Oligocene), from the Kokoamu Greensand Formation of New Zealand. It was historically referred to as Palaeeudyptes.

Pachydyptes (Pachydyptes ponderosus), also known as the New Zealand giant penguin is an extinct genus of penguin. This taxon is known from a few bones from Late Eocene (37 to 34 MYA) rocks in the area of Otago, which were found in two clades near a base of a tree (Ksepka et al., 2006).

Inkayacu is a genus of extinct penguins. It lived in what is now Peru during the Late Eocene, around 36 million years ago. The only species, I. paracasensis, was named from a single nearly complete skeleton discovered in 2008. It includes fossilized feathers, the first known in penguins. A study of the melanosomes, pigment-containing organelles within the feathers, indicated that they were gray or reddish brown. This differs from modern penguins, which get their dark black-brown feathers from unique melanosomes that are large and ellipsoidal.

Kumimanu is an extinct genus of giant penguin, which lived around 56 to 60 million years ago. The type species is Kumimanu biceae, which arose after the extinction of the non-avian dinosaurs. Fossils were found in New Zealand, and the discovery was announced in December 2017. A second species, Kumimanu fordycei, was named in February 2023, though some researchers consider it synonymous with the type species.

Palaeeudyptes is an extinct genus of large penguins, currently containing four accepted species. They were probably larger than almost all living penguins, with the smaller species being about the size of an emperor penguin, and the largest species, Palaeeudyptes klekowskii, estimated to reach long (measuring tip of beak to tail) and weighed up to .

Palaeeudyptinae, the giant penguins, is a paraphyletic subfamily of prehistoric penguins. It includes several genera of medium-sized to very large species, such as Icadyptes salasi, Palaeeudyptes marplesi, Anthropornis nordenskjoeldi, and Pachydyptes ponderosus. Icadyptes reached in height, while members of Palaeeudyptes and Anthropornis grew even taller and were some of the largest penguins to have ever existed. The massive P. ponderosus may have weighed at least as much as an adult human.

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.

Crossvallia is an extinct genus of penguins. It includes two species, C. unienwillia and ?C. waiparensis. Their anatomy suggests that the genus is closely related to the Anthropornithinae.

Palaeospheniscus is an extinct genus of penguins belonging to the subfamily Palaeospheniscinae. These penguins are apparently not closely related to the modern genus Spheniscus.

Paraptenodytes is an extinct genus of penguins which contains two or three species sized between a Magellanic penguin and an emperor penguin (Aptenodytes forsteri). They are known from fossil bones ranging from a partial skeleton and some additional material in the case of P. antarcticus, the type specimen for the genus, and a single humerus in the case of P. brodkorbi. The latter species is therefore often considered invalid; a recent study considers it indeed valid, but distinct enough not to belong into Paraptenodytes. The fossils were found in the Santa Cruz and Chubut Provinces of Patagon

Inguza predemersus is an extinct species of penguin. It was formerly placed in the genus Spheniscus and presumed to be a close relative of the African penguin, but after its well-distinct tarsometatarsus was found, it was moved into its present monotypic genus. The known fossils specimens were found in Late Pliocene rocks in a quarry at Langebaanweg, South Africa, from about 5 million years ago.

Anthropodyptes is a poorly known monotypic genus of extinct penguin. It contains the single species Anthropodyptes gilli, known from a Middle Miocene humerus from Australia. The bone is somewhat similar to those found in members of the New Zealand genus Archaeospheniscus and thus this genus might, like them, belong to the subfamily Palaeeudyptinae.

Duntroonornis parvus, also referred to as the Duntroon penguin, is a genus and species of extinct penguin from the Late Oligocene of New Zealand. The penguin was relatively small, similar in size to the Fiordland crested penguin. It was described by Brian Marples in 1952 from fossil material (a left tarsometatarsus) collected near Duntroon, from the Kokoamu Greensand Formation, near the border between the Canterbury and Otago regions of the South Island. Fossils found at the Hakataramea Valley may also be referrable to this species. The genus name Duntroonornis means "Duntroon bird". The speci
