The genus Eudyptula contains two species of penguin, found in southern Australia, Tasmania, and New Zealand. They are commonly known as the little penguin, little blue penguin, or, in Australia, fairy penguin. In the language of the Māori people of New Zealand, little penguins are known as kororā.
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. 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.
Ichthyornithes is an extinct group of toothed avialans very closely related to the common ancestor of all modern birds. They are known from fossil remains found throughout the late Cretaceous period of North America, though only two genera, Ichthyornis and Janavis, are represented by complete enough fossils to have been named. Ichthyornitheans became extinct at the Cretaceous–Paleogene boundary, along with enantiornitheans, all other non-avian dinosaurs, and many other animal and plant groups.
The Chatham penguin, also known as the Chatham crested penguin, Chatham Islands penguin, or Warham's penguin, is an extinct species of crested penguin previously endemic to the Chatham Islands of New Zealand. It is known only from subfossil bones and probably became extinct within 150–200 years after Polynesians arrived in the Chatham Islands around 1500 CE.
Icadyptes is an extinct genus of giant penguins from the Late Eocene tropics of South America.
Novacaesareala is a genus of prehistoric bird. It is known only from the fossil remains of a single partial wing of the species Novacaesareala hungerfordi. This was found in Hornerstown Formation deposits, probably from the latest Cretaceous (Maastrichtian) or Early Paleocene (Danian); it lived around 66-65 million years ago on the western shores of the Atlantic, where now is New Jersey.
Scarlett's duck is an extinct duck species from New Zealand which was closely related to the Australian pink-eared duck. The scientific name commemorates the late New Zealand ornithologist and palaeontologist Ron Scarlett who discovered the holotype in 1941. However, previously undescribed bones of the species found in 1903 were rediscovered in the Otago Museum in 1998. At least 32 fossil remains from deposits in Pyramid Valley, at Ngāpara in the South Island, and at Lake Poukawa in the North Island are in museum collections.
Scarlett's shearwater is an extinct species of seabird in the petrel family Procellariidae. Its common name commemorates New Zealand palaeontologist Ron Scarlett, who recognised the bird's subfossil remains represented a distinct species.
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, from the Kokoamu Greensand Formation of New Zealand. It was historically referred to as Palaeeudyptes.
Australornis is a genus of extinct seabird discovered in New Zealand. It lived in the Paleocene epoch, 60.5 to 61.6 million years ago (Ma). The type species name originates from australis, Latin for "southern", and ornis, the Greek word for "bird", and lovei commemorates Leigh Love, an amateur paleontologist who discovered it.
The St Bathans fauna is found in the lower Bannockburn Formation of the Manuherikia Group of Central Otago, in the South Island of New Zealand. It comprises a suite of fossilised prehistoric animals from the late Early Miocene (Altonian) period, with an age range of 19–16 million years ago.
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.
Muriwaimanu is an extinct genus of early penguin.
Sequiwaimanu is an extinct genus of early penguin. The type species, Sequiwaimanu rosieae, was named and described by Gerald Mayr in 2018.
Heracles inexpectatus is a giant fossil parrot species from New Zealand, assigned to a monotypic genus Heracles, that lived during the early Miocene approximately 16 to 19 million years ago. The species was described from two tibiotarsus fossils discovered in 2008 at Saint Bathans, Otago, New Zealand. It is believed that the species stood up to 90 cm tall and weighed approximately 7 kg (15 lb). Initial analysis suggests that this parrot is from the order Psittaciformes and from the superfamily Strigopoidea, which consists of three confirmed primitive genera of parrots: Nestor, Strigops (Kākāpō) and the fossil Nelepsittacus. It may have been the ancestor of the kākāpō.
The Takatika Grit is a geologic formation in Chatham Islands, New Zealand. It preserves fossils dating back to the Paleocene period, although it also preserves disturbed and re-worked Maastrichtian and Campanian microfossils and tetrapod fossils. A 2017 study found that it dated to late Early to Mid Paleocene on the basis of dinoflagellates. It has been subdivided into two informal units, a lower phosphatic unit containing bones and nodular phosphatic layers, and an upper unit with abundant sponge remains and siliceous microfossils.
Kupoupou is an extinct genus of bird from the Paleocene-aged Takatika Grit of the Chatham Islands, New Zealand which is believed to be the oldest penguin genus known to date. The type species, K. stilwelli, was named and described by Blokland et al. in 2019.
Petradyptes is an extinct genus of penguin that lived during the Late Paleocene epoch, between 60 and 55 million years ago. The genus currently contains one known species, Petradyptes stonehousei.
Robert Ewan Fordyce was a New Zealand palaeontologist. He specialised in the evolution of whales and dolphins (Cetacea) and early penguins.
Clymenoptilon is an extinct genus of phaethontiform bird related to modern tropicbirds. It contains a single species, C. novaezealandicum from the Paleocene-aged Waipara Greensand of New Zealand. Its name references Clymene, the mother of Phaethon in Greek mythology.
