The sunbittern is a bittern-like bird of tropical regions of the Americas, and the sole member of the family Eurypygidae and genus Eurypyga. It is found in Central and South America, and has three subspecies. The sunbittern shows both morphological and molecular similarities with the kagu of New Caledonia, indicating a gondwanic origin, both species being placed in the clade Eurypygiformes.
The biodiversity of New Caledonia is of exceptional biological and paleoecological interest. It is frequently referred to as a biodiversity hotspot. The country is a large South Pacific archipelago with a total land area of more than 18,000 square kilometres (6,900 sq mi). The terrain includes a variety of reefs, atolls, small islands, and a variety of topographical and edaphic regions on the largest island, all of which promote the development of unusually concentrated biodiversity. The region's climate is oceanic and tropical.
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.
Rhynochetos is a genus of ground-dwelling birds in the monotypic family Rhynochetidae. It contains two species, both endemic to New Caledonia, one of which is extinct.
Mekosuchus is a genus of extinct Australasian mekosuchine crocodilian. Species of Mekosuchus were generally small-sized, terrestrial animals with short, blunt-snouted heads and strong limbs. Four species are currently recognized, M. inexpectatus, M. whitehunterensis, M. sanderi and M. kalpokasi, all known primarily from fragmentary remains.
The St. Croix macaw or Puerto Rican macaw, is an extinct species of macaw whose remains have been found on the Caribbean islands of St. Croix and Puerto Rico. It was described in 1937 based on a tibiotarsus leg bone unearthed from a kitchen midden at a pre-Columbian site on St. Croix. A second specimen consisting of various bones from a similar site on Puerto Rico was described in 2008, while a coracoid from Montserrat may belong to this or another extinct species of macaw. The St. Croix macaw is one of 13 extinct macaw species that have been proposed to have lived on the Caribbean islands. Macaws were frequently transported long distances by humans in prehistoric and historical times, so it is impossible to know whether species known only from bones or accounts were native or imported.
Sylviornis is an extinct genus of large, flightless bird that was endemic to the islands of New Caledonia in the Western Pacific. It is considered to constitute one of two genera in the extinct family Sylviornithidae, alongside Megavitiornis from Fiji, which are related to the Galliformes, the group containing the turkeys, chickens, quails and pheasants. Sylviornis was never encountered alive by scientists, but it is known from many thousands of subfossil bones found in deposits, some of them from the Holocene, on New Caledonia and the adjacent Île des Pins. It was likely hunted to extinction shortly after the first human arrival to New Caledonia around 1500 BC.
The New Caledonian gallinule was a species of bird in the family Rallidae. It was endemic to New Caledonia and probably became extinct due to hunting, habitat loss and the presence of invasive species following human settlement of the island. However a passage from an 1860 article refers to birds the size of turkeys being present in marshy areas of New Caledone, suggesting that it may have survived into historic times. The native name n'dino is thought to refer to this bird.
Paleontology or palaeontology is the study of prehistoric life forms on Earth through the examination of plant and animal fossils. This includes the study of body fossils, tracks (ichnites), burrows, cast-off parts, fossilised feces (coprolites), palynomorphs and chemical residues. Because humans have encountered fossils for millennia, paleontology has a long history both before and after becoming formalized as a science. This article records significant discoveries and events related to paleontology that occurred or were published in the year 1989.
The pile-builder megapode is an extinct species of megapode. The subfossil remains were found by Jean-Christophe Balouet and Storrs L. Olson in the Pindai Caves of New Caledonia. Its remains have also been found on Tonga.
The kagu or cagou is a crested, long-legged, and bluish-grey bird endemic to the dense mountain forests of New Caledonia. It is the only surviving member of the genus Rhynochetos and the family Rhynochetidae, although a second species has been described from the fossil record.
The Kanaka pigeon, also known as the great green pigeon or greater maned pigeon, is an extinct species of pigeon. It was probably hunted to extinction by the early settlers of New Caledonia and Tonga around 2,500 years ago. It was described from subfossil remains found at the Pindai Caves of New Caledonia. The specific epithet is a Latinisation of kanaka, the name of the native Melanesian people of New Caledonia. It was about 25% larger than its closest living relative, the Nicobar pigeon.
Eurypygiformes is an order formed by the kagus, comprising two species in the family Rhynochetidae endemic to New Caledonia, and the sunbittern from the tropical regions of the Americas. Its closest relatives appear to be the tropicbirds of the tropical Atlantic, Indian, and Pacific oceans.
Jean-Christophe Balouet was a French palaeontologist. He has collaborated extensively with Storrs Olson of the Smithsonian Institution on palaeornithological research on the extinct birds of New Caledonia in the south-west Pacific region.
The powerful goshawk, also referred to as the greater New Caledonian goshawk, is an extinct species of bird of prey in the family Accipitridae. It was endemic to the island of New Caledonia in Melanesia in the southwest Pacific region. It was described from subfossil bones found at the Pindai Caves paleontological site on the west coast of Grande Terre. The Latin specific epithet efficax means "powerful".
The gracile goshawk is an extinct species of bird of prey in the family Accipitridae. It was endemic to the island of New Caledonia in Melanesia in the southwest Pacific region. It was described from subfossil bones found at the Pindai Caves paleontological site on the west coast of Grande Terre. The Latin specific epithet quartus means "fourth"; it was the fourth Accipiter species recorded from New Caledonia. The gracile goshawk was smaller and much less robust than its contemporary congener the powerful goshawk, remains of which were also found at the same site.
The New Caledonian ground dove is a large, extinct species of Pampusana ground dove in the pigeon family, and the largest member of its genus. It was endemic to the island of New Caledonia in Melanesia in the south-west Pacific region. It was described from subfossil bones found at the Pindai Caves paleontological site on the west coast of Grande Terre. The specific epithet refers to the slender and elongated tarsometatarsus, or lower leg bone, of the species.
The New Caledonian barn owl, also referred to as Letocart's barn owl, is an extinct species of owl in the barn owl family. It was endemic to the island of New Caledonia in Melanesia in the southwestern Pacific region. It was described from Holocene aged subfossil bones found at the Gilles Cave paleontological site on the west coast of Grande Terre. The holotype is a complete adult left femur, held by the Muséum national d'histoire naturelle in Paris. The owl was described as Tyto? letocarti, indicating uncertainty as to generic placement at the time. The specific epithet honours Yves Letocart of New Caledonia's Water and Forest Service, who was active in bird conservation and paleontological work on the island.
