The adzebills, genus Aptornis, were two closely related bird species, the North Island adzebill,, and the South Island adzebill,, of the extinct family Aptornithidae. The family was endemic to New Zealand. A tentative fossil species,, is known from the Miocene Saint Bathans fauna.
The Saint Bathans mammal is a currently unnamed extinct primitive mammal from the Early Miocene of New Zealand. A member of the Saint Bathans fauna, it is notable for being a late-surviving "archaic" mammal species, neither a placental nor a marsupial. It also provides evidence that flightless fully terrestrial mammals did in fact once live in Zealandia. This is in contrast to modern New Zealand, where bats, cetaceans and seals are the only non-introduced mammals in the otherwise bird-dominated faunas.
Icarops is an extinct, possibly paraphyletic genus of mystacine bat with three described species. The genus is known from fossils found at Riversleigh, north-western Queensland, Bullock Creek, Northern Territory, and Lake Ngapakaldi to Lake Palankarinna Fossil Area South Australia Australia. The fossils date from the late Oligocene to early Miocene.
Galaxias angustiventris is an extinct species of bony fish in the genus Galaxias. It existed in what is now New Zealand in the early Miocene epoch. It was described by Werner Schwarzhans, R. Paul Scofield, Alan J. D. Tennyson, Jennifer P. Worthy and Trevor H. Worthy in 2012.
Galaxias brevicauda is an extinct species of bony fish in the genus Galaxias. It existed in what is now New Zealand in the early Miocene epoch. It was described by Werner Schwarzhans, R. Paul Scofield, Alan J. D. Tennyson, Jennifer P. Worthy and Trevor H. Worthy in 2012.
Galaxias bobmcdowalli is an extinct species of bony fish in the genus Galaxias. It existed in what is now New Zealand in the early Miocene epoch. It was described by Werner Schwarzhans, R. Paul Scofield, Alan J. D. Tennyson, Jennifer P. Worthy and Trevor H. Worthy in 2012.
Galaxias papilionis is an extinct species of bony fish in the genus Galaxias. It existed in what is now New Zealand in the early Miocene epoch. It was described by Werner Schwarzhans, R. Paul Scofield, Alan J. D. Tennyson, Jennifer P. Worthy and Trevor H. Worthy in 2012.
Galaxias parvirostris is an extinct species of bony fish in the genus Galaxias. It existed in what is now New Zealand in the early Miocene epoch. It was described by Werner Schwarzhans, R. Paul Scofield, Alan J. D. Tennyson, Jennifer P. Worthy and Trevor H. Worthy in 2012.
Galaxias tabidus is an extinct species of bony fish in the genus Galaxias. It existed in what is now New Zealand in the early Miocene epoch. It was described by Werner Schwarzhans, R. Paul Scofield, Alan J. D. Tennyson, Jennifer P. Worthy and Trevor H. Worthy in 2012.
Mataichthys is an extinct genus of sleeper gobies which lived in what is now New Zealand in the early Miocene period. It was described by Werner Schwarzhans, R. Paul Scofield, Alan J. D. Tennyson, Jennifer P. Worthy and Trevor H. Worthy in 2012, and contains the species Mataichthys bictenatus, Mataichthys procerus, Mataichthys rhinoceros, and Mataichthys taurinus.
Prototroctes modestus is an extinct species of bony fish in the family Retropinnidae. It existed in what is now New Zealand in the early Miocene epoch. It was described by Werner Schwarzhans, R. Paul Scofield, Alan J. D. Tennyson, Jennifer P. Worthy and Trevor H. Worthy in 2012.
Nelepsittacus is a genus of extinct New Zealand parrots that is closely related to the genus Nestor. It consists of four species, of which three have been named so far. The species are all known from the early Miocene Saint Bathans Fauna from the Lower Bannockburn Formation in Otago in New Zealand.
Matuku otagoense, also referred to as the Saint Bathans heron, is an extinct genus and species of heron from the Early Miocene of New Zealand. It was described from fossil material collected in 2007 from the Saint Bathans fauna of the Bannockburn Formation in Otago, South Island. It was a contemporary of the much smaller Saint Bathans bittern, remains of which have been found in the same sediments. The genus name matuku is a Māori-language word meaning “heron” or "bittern". The specific epithet is a latinisation of the name of the Otago region where the descriptive material was collected.
Rupephaps taketake, also referred to as the Saint Bathans pigeon, is an extinct species of pigeon from the Miocene of New Zealand. It is the first species of columbid to be described from pre-Pliocene fossil deposits in the Australasian region.
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.
Manuherikia is a genus of extinct species of ducks from the Miocene of New Zealand. It was described from fossil material of the Saint Bathans Fauna, in the lower Bannockburn Formation of the Manuherikia Group, found by the Manuherikia River in the Central Otago region of the South Island. The genus name comes from the name of the geological formation in which the fossils were found and, ultimately, from the Manuherikia River and its valley.
Miotadorna is a genus of extinct tadornine ducks from the Miocene of New Zealand. It contains two species, M. sanctibathansi, and M. catrionae.
The Manuherikia Group is a fluvial-lacustrine sedimentary fill in the Central Otago area of New Zealand, at the site of the prehistoric Lake Manuherikia. The area consists of a valley and ridge topography, with a series of schist-greywacke mountains at roughly ninety degrees to each other. The Manuherika Group occurs in the current basins, and occasionally on the mountains themselves.
Kuiornis indicator is an extinct New Zealand wren (Acanthisittidae) known from the early Miocene St Bathans fauna in Central Otago. It is known from a holotype proximal right tarsometatarsus. Amongst acanthisittids it is most closely related to the living rifleman.
Hakawai is an extinct genus of prehistoric birds that lived during the early Miocene to middle Miocene in New Zealand. According to a 2015 paper, Hakawai melvillei was a representative of a large group of birds that comprises the seedsnipes of family Thinocoridae) and the plains-wanderer. This discovery sheds light on evolutionary processes at work when South America, Antarctica, Australia, and New Zealand were all parts of Gondwanaland.
