Tahuata Rail
The Tahuata rail (''Gallirallus roletti'') is an extinction, extinct species of flightless bird in the Rallidae, or rail family (biology), family. History It was described in 2007 from subfossil remains found in 1984-1985 by Barry Rolett at the Hanamiai archaeological site, on the island of Tahuata in the Marquesas Islands of French Polynesia. The site dates to about 1000 yr Before Present, BP, from the early period of human settlement of the island.(subscription required) Etymology The species was named in honour of archaeologist Barry V. Rolett, whose research in the Marquesas has been of both archaeological and biological importance, particularly for the excavation of an extensive series of ''Gallirallus'' bones at the Hanamiai site.

Holocene
The Holocene ( ) is the current geological epoch. It began approximately 11,650 cal years Before Present (), after the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch, called the Flandrian interglacial.Oxford University Press – Why Geography Matters: More Than Ever (book) – "Holocene Humanity" section https://books.google.com/books?id=7P0_sWIcBNsC The Holocene corresponds with the rapid proliferation, growth and impacts of the human species worldwide, including all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban living in the present.

Late Quaternary Prehistoric Birds
Late Quaternary prehistoric birds are avian taxa that became extinct during the Late Quaternary – the Holocene or Late Pleistocene – and before recorded history, or more precisely, before they could be studied alive by ornithological science. They became extinct before the period of global scientific exploration that started in the late 15th century. In other words, this list basically deals with extinctions between 40,000 BC and 1500 AD. For the purposes of this article, a "bird" is any member of the clade Neornithes, that is, any descendant of the most recent common ancestor of all currently living birds. The birds are known from their remains, which are subfossil (not fossilized, or not completely fossilized). Some are also known from folk memory, as in the case of Haast's eagle in New Zealand. As the remains are not completely fossilized, they may yield organic material for molecular analyses to provide additional clues for resolving their taxonomic affil ...

Extinct Birds Of Oceania
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, ma ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Birds Of The Marquesas Islands
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. Birds ...

Gallirallus
''Gallirallus'' is a genus of rails that live in the Australasian-Pacific region. The genus is characterised by an ability to colonise relatively small and isolated islands and thereafter to evolve flightless forms, many of which became extinct following Polynesian settlement. Taxonomy Following recent taxonomic revisions, there is only one known extant species in this genus along with several extinct species of dubious classification, with all other species being moved to ''Hypotaenidia'', ''Cabalus'', or '' Aptenorallus''. Description Many of the rails, including the well-known weka of New Zealand, are flightless or nearly so. Many of the resultant flightless island endemics became extinct after the arrival of humans, which hunted these birds for food, introduced novel predators like rats, dogs or pigs, and upset the local ecosystems. A common Polynesian name of these rails, mainly relatives of ''G. philippensis'', is ''veka''/''weka'' (in English, this name is generally l ...

Before Present
Before Present (BP) years, or "years before present", is a time scale used mainly in archaeology, geology and other scientific disciplines to specify when events occurred relative to the origin of practical radiocarbon dating in the 1950s. Because the "present" time changes, standard practice is to use 1 January 1950 as the commencement date (epoch) of the age scale. The abbreviation "BP" has been interpreted retrospectively as "Before Physics", which refers to the time before nuclear weapons testing artificially altered the proportion of the carbon isotopes in the atmosphere, which scientists must now account for. In a convention that is not always observed, many sources restrict the use of BP dates to those produced with radiocarbon dating; the alternative notation RCYBP stands for the explicit "radio carbon years before present". Usage The BP scale is sometimes used for dates established by means other than radiocarbon dating, such as stratigraphy. This usage differs from t ...

Marquesas Islands
The Marquesas Islands (; french: Îles Marquises or ' or '; Marquesan: ' ( North Marquesan) and ' ( South Marquesan), both meaning "the land of men") are a group of volcanic islands in French Polynesia, an overseas collectivity of France in the southern Pacific Ocean. Their highest point is the peak of Mount Oave (french: Mont Oave, links=no) on Ua Pou island, at 1,230 m (4,035 ft) above sea level. Archaeological research suggests the islands were colonized in the 10th century AD by voyagers from West Polynesia. Over the centuries that followed, the islands have maintained a "remarkably uniform culture, biology and language". The Marquesas were named after the 16th century Spanish Viceroy of Peru, the Marquis of Cañete ( es, Marqués de Cañete, italic=unset) by navigator , who visited them in 1595. The Marquesas Islands constitute one of the five administrative divisions (') of French Polynesia. The capital of the Marquesas Islands' administrative subdivision is t ...

Tahuata
Tahuata is the smallest of the inhabited Marquesas Islands, in French Polynesia, an overseas territory of France in the Pacific Ocean. It is located 4 km (2.5 mi.) to the south of the western end of Hiva Oa, across the Canal du Bordelais, called Ha‘ava in Marquesan. History Archæological evidence indicates that Tahuata was inhabited by Polynesians as early as AD 200. In later pre-European times, the tribes of Tahuata were allied with the tribes from the Nuku province of Hiva Oa, and the island was considered a dependency of that province. The first recorded sighting by Europeans was by the Spanish expedition of Álvaro de Mandaña on 22 July 1595. They charted the island as ''Santa Cristina''. They landed at Vaitahu that they named ''Madre de Dios'' (God's Mother in Spanish). According to the Spanish accounts Tahuata had fowls, fish, sugar cane, plantains, nuts and fruits. The existent town was built on two sides of a rectangular space, the houses being of timbe ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
