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.
Pycnodus is an extinct genus of ray-finned fish from the Eocene period. It is wastebasket taxon, although many fossils from Jurassic or Cretaceous are assigned to this genus, only Eocene species, P. apodus is valid. As its name suggests, it is the type genus of Pycnodontiformes.
Archaeospheniscus is an extinct genus of large penguins. It currently contains three species, known from somewhat fragmentary remains. A. wimani, the smallest species, was found in Middle or Late Eocene strata 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 at Duntroon, New Zealand.
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, having 2 meters (6.6 ft) long and weighed up to 116 kg (256 lb).
Archaeospheniscus wimani is an extinct species of penguin. It was the smallest species of the genus Archaeospheniscus, being approximately 75 to 85 centimetres high, or about the size of a gentoo penguin. It is also the oldest known species of its genus, as its remains were found in Middle or Late Eocene strata of the La Meseta Formation on Seymour Island, Antarctica. It is known from a fair number of bones.
Archaeospheniscus lopdelli was the largest species of the extinct penguin genus Archaeospheniscus, standing about 90–120 cm (35–47 in) high, or somewhat less than the extant emperor penguin. It is only known from bones of a single individual which was found in the Late Oligocene Kokoamu Greensand Formation at Duntroon, New Zealand. Bones apparently belonging to this species are now also known from the Late Eocene La Meseta Formation on Seymour Island, Antarctica.
Palaeeudyptes antarcticus, also referred to as the narrow-flippered penguin, is the type species of the extinct penguin genus Palaeeudyptes. It was a huge species, albeit probably with a large size variation. Although the size range can only be loosely estimated, the birds seem to have stood between 43 and 55 inches high in life, placing this species and its congener Palaeeudyptes marplesi among the largest penguin species known. It was the last known Palaeeudyptes species, and although the exact time when it lived is not precisely determined, it may have evolved from P. marplesi, or they might even have been a single species which slightly decreased in size over time.
Palaeeudyptes gunnari is an extinct species of the extinct penguin genus Palaeeudyptes. It was a bit smaller than its congener Palaeeudyptes antarcticus of New Zealand, standing between 110 and 125 cm high, approximately the size of the emperor penguin. It is known from dozens of fossil bones from Middle or Late Eocene strata of the La Meseta Formation on Seymour Island, Antarctica. Initially, it was described as a separate genus, Eosphaeniscus. However, this was based on a single weathered and broken tarsometatarsus. Better material recovered later showed that the species belongs into the present genus.
Paraptenodytes brodkorbi is a proposed, but possibly invalid, species of extinct penguin in the genus Paraptenodytes. The bird was probably about the size of a king penguin. Known material is limited to a single humerus, Early Miocene in age, found in the Monte León Formation near Puerto San Julián in Santa Cruz Province, Argentina. It exists as an unnumbered specimen in the collection of the Museo Argentino de Ciencias Naturales.
The La Meseta Formation is a sedimentary sequence deposited during the Eocene on Seymour Island off the coast of the Antarctic Peninsula. It is noted for its fossils, which include both marine organisms and the only terrestrial vertebrate fossils from the Cenozoic of Antarctica.
Glyptosaurinae is an extinct subfamily of anguid lizards that lived in the Northern Hemisphere during the Late Cretaceous and the Paleogene.
Murusraptor is a genus of carnivorous megaraptoran theropod dinosaur from the Sierra Barrosa Formation, part of the Neuquén Group of Patagonia, in Argentina, South America. It is known from a single specimen that consists of a partial skull, ribs, partial pelvis, leg and other assorted skeletal elements.
Australonyx is an extinct genus of ground sloths, endemic to South America during the Late Pleistocene. It was found in Brazil.
Notocetus is an extinct genus of river dolphin belonging to Squalodelphinidae. Known specimens have been found in Early Miocene marine deposits from Argentina, Italy and Peru.
Vegaviidae is an extinct family of birds of uncertain phylogenetic placement, which existed during the Late Cretaceous and possibly the Paleocene. Definitive fossils attributed to the family have only been found in Antarctica, though other fossils from the Southern Hemisphere including Chile and New Zealand may represent this group. The putative Campanian vegaviid from Canada known as Maaqwi, more likely belongs to the Procellariformes.
Delphinornis is an extinct genus of penguins that lived around the middle Eocene to the middle Miocene in Antarctica.
The Gaiman Formation, in older literature also referred to as Patagonian Marine Formation, is a fossiliferous geologic formation of the Peninsula Valdés Basin in the eastern Chubut Province of northwestern Patagonia, eastern Argentina.
Jonoichthys is an extinct genus of marine ray-finned fish from the Upper Jurassic of Argentina. The type and only known species is Jonoichthys challwa. The fossil remains of J. challwa were recovered from the Vaca Muerta Formation, in Neuquén province, Argentina. It belongs to the family Aspidorhynchidae, within Aspidorhynchiformes.
Notiolofos is an extinct genus of sparnotheriodontid ungulate from the order Litopterna. The animal lived during the Eocene, in modern-day Antarctica. The genus contains two species, N. arquinotiensis, the type species, and N. regueroi.
