Maui Nui Large-billed Moa-nalo
The Maui Nui large-billed moa-nalo (''Thambetochen chauliodous''), also known as the Maui Nui moa-nalo, is one of two species of moa-nalo in the genus ''Thambetochen''. Moa-nalo are a group of extinct, flightless, large goose-like ducks, which evolved in the Hawaiian Islands of the North Pacific Ocean. Distribution and habitat The genus and species were originally described in 1976 from subfossil material collected from the Moomomi Dunes, on the island of Molokai. Remains of the bird have also been recovered from Ilio Point on Molokai as well as from lava tubes on the southern slopes of the volcanic mountain of Haleakalā on the nearby island of Maui. Both Molokai and Maui are parts of what used to be the much larger prehistoric island of Maui Nui, to which the species appears to have been endemic. The bird evidently shared the island with another moa-nalo—the smaller small-billed moa-nalo The small-billed moa-nalo (''Ptaiochen pau''), also known as the stumbling moa-nalo, is ...

Holocene
The Holocene () is the current geologic time scale, geological epoch, beginning approximately 11,700 years ago. It follows the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene is an interglacial period within the ongoing Ice age, glacial cycles of the Quaternary, and is equivalent to Marine isotope stages, Marine Isotope Stage 1. The Holocene correlates with the last maximum axial tilt towards the Sun of the Earth#Axial tilt and seasons, Earth's obliquity. The Holocene corresponds with the rapid proliferation, growth, and impacts of the human species worldwide, including Recorded history, all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban culture, urban living in the present. The human impact on modern-era Earth and its ecosystems may be considered of global significance for th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maui Nui
Maui Nui is a modern Geology, geologists' name given to a prehistoric Hawaii, Hawaiian island and the corresponding modern Biogeography, biogeographic region. Maui Nui is composed of four modern islands: Maui, Molokai, Molokaʻi, Lanai, Lānaʻi, and Kahoʻolawe. Administratively, the four modern islands comprise Maui County, Hawaii, Maui County (and a tiny part of Molokaʻi called Kalawao County, Hawaii, Kalawao County). Long after the breakup of Maui Nui, the four modern islands retained plant and animal life similar to each other. Thus, Maui Nui is not only a prehistoric island but also a modern Biogeography, biogeographic region. Geology Maui Nui formed and broke up during the Pleistocene Epoch, which lasted from about 2.58 million to 11,700 years ago. Maui Nui is built from seven Shield volcano, shield volcanoes. The three oldest are Penguin Bank, West Molokai Volcano, West Molokaʻi, and East Molokai Volcano, East Molokaʻi, which probably range from slightly over to sl ...

Maui County, Hawaii
Maui County (), officially the County of Maui, is a county in the U.S. state of Hawaii. It consists of the islands of Maui, Lānai, Molokai (except for a portion of Molokai that comprises Kalawao County), Kahoolawe, and Molokini. The latter two are uninhabited. As of the 2020 census, the population was 164,754. The county seat is Wailuku. Maui County is included in the Kahului-Wailuku-Lahaina, HI Metropolitan Statistical Area. Government Maui County has a quasi- mayor-council form of municipal government. Unlike traditional municipal governments, the county government is established by the state legislature by statute and is not chartered. Executive authority is vested in the mayor, elected by the voters on a nonpartisan basis to a four-year term (with a limit of two consecutive full terms). Legislative authority is vested in the nine-member Maui County Council. All seats in the county council have residency requirements, but all Maui County voters may vote in elect ...

Extinct Flightless Birds
Extinction is the termination of an organism by the death of its last member. A taxon may become functionally extinct before the death of its last member if it loses the capacity to reproduce and recover. As 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. Over five billion species are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryotes globally, possibly many times more if microorganisms are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, and mammoths. Through evolution, species arise through the process of speciation. Species become extinct when they are no longer able to survive in changing conditions or against ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Late Quaternary Prehistoric Birds
Late Quaternary prehistoric birds are Bird, avian taxa that became extinct during the Late Quaternary – the Late Pleistocene or Early Holocene – and before recorded history, specifically before they could be studied alive by ornithological science. They had died out before the period of global scientific exploration that started in the late 15th century. In other words, this list deals with avian extinctions between Upper Paleolithic, 40,000 BC and AD 1500. 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; as the remains are not completely fossilized, they may yield organic material for molecular analyses to provide additional clues for resolving their Taxonomy (biology), taxonomic affiliations. Some birds are also known from folk memory, as in the case of Haast's eagle in New Zeala ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anatinae
The Anatinae are a subfamily of the family Anatidae (swans, geese and ducks). Its surviving members are the dabbling ducks, which feed mainly at the surface rather than by diving. The other members of the Anatinae are the extinct moa-nalo, a young but highly apomorphic lineage derived from the dabbling ducks. There has been much debate about the systematical status and which ducks belong to the Anatinae. Some taxonomic authorities only include the dabbling ducks and their close relatives, the extinct moa-nalos. Alternatively, the Anatinae are considered to include most " ducks", and the dabbling ducks form a tribe Anatini within these. The classification as presented here more appropriately reflects the remaining uncertainty about the interrelationships of the major lineages of Anatidae (waterfowl). Systematics The dabbling duck group, of worldwide distribution, was delimited in a 1986 study to include eight genera and some 50–60 living species. However, Salvadori's te ...

Helen James
Helen Frances James (born May 22, 1956) is an American paleontologist and paleornithologist who has published extensively on the fossil birds of the Hawaiian Islands. She is the curator in charge of birds in the Department of Vertebrate Zoology at the National Museum of Natural History in Washington, D.C. Early life James was born in a U.S. Army hospital in Hot Springs, Arkansas on May 22, 1956, to two ecologists. She was brought up on a farm at the base of Kessler Mountain near Fayetteville, in the Arkansas Ozarks. At age eight, her family moved up slope to a custom-built house in the woods, where she developed an interest in natural history and archaeology. James' parents encouraged an appreciation for nature in her and her sisters, taking them on trips within the Ozarks, to the American southwest, and to Mexico. James found some Amerindian artifacts on these excursions, leading her to join the Northwest Arkansas Archaeological Association at age twelve. At age 14, her fat ...
