Upland Moa
The upland moa (''Megalapteryx didinus'') was a species of moa endemic to New Zealand. It was a ratite, a grouping of flightless birds with no keel on the sternum. It was the last moa species to become extinct, vanishing in 1445 CE, and was predominantly found in alpine and sub-alpine environments. Taxonomy In 2005, a genetic study suggested that ''M. benhami'', which had previously been considered a junior synonym of ''M. didinus'', may have been a valid species after all. The cladogram below follows a 2009 analysis by Bunce ''et al.'': Description At less than 1 metre tall and about 17 to 34 kilograms, the upland moa was among the smallest of the moa species. Unlike other moas, it had feathers covering all of its body but the beak and the soles of its feet, an adaptation to its cold environment.Flannery, Tim, "A Gap in Nature: Discovering the World's Extinct Animals", October 2001, Scientists believed in the past that the upland moa held its neck and head upright; howev ...

Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological Epoch (geology), epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing Great American Interchang ...

Pachyornis Elephantopus
The heavy-footed moa (''Pachyornis elephantopus'') is a species of moa from the lesser moa family. The heavy-footed moa was widespread only in the South Island of New Zealand, and its habitat was the lowlands (shrublands, dunelands, grasslands, and forests). The moa were ratites, flightless birds with a sternum without a keel. They also have a distinctive palate. The origin of these birds is becoming clearer as it is now believed that early ancestors of these birds were able to fly and flew to the southern areas in which they have been found.Davies, S. J. J. F. (2003) The heavy-footed moa was about tall, and weighed as much as .Olliver, Narena (2005) Three complete or partially complete moa eggs in museum collections are considered eggs of the heavy-footed moa, all sourced from Otago. These have an average length of 226mm and a width of 158mm, making these the largest moa eggs behind the single South Island giant moa egg specimen. Discovery The heavy-footed moa was discovered ...

Auckland War Memorial Museum
The Auckland War Memorial Museum Tāmaki Paenga Hira (or simply the Auckland Museum) is one of New Zealand's most important museums and war memorials. Its collections concentrate on New Zealand history (and especially the history of the Auckland Region), natural history, and military history. The present museum building was constructed in the 1920s in the neo-classicist style, and sits on a grassed plinth (the remains of a dormant volcano) in the Auckland Domain, a large public park close to the Auckland CBD. Auckland Museum's collections and exhibits began in 1852. In 1867 Aucklanders formed a learned society – the Auckland Philosophical Society, later the Auckland Institute. Within a few years the society merged with the museum and '' Auckland Institute and Museum'' was the organisation's name until 1996. Auckland War Memorial Museum was the name of the new building opened in 1929, but since 1996 was more commonly used for the institution as well. From 1991 to 2003 the muse ...

Tussock (grass)
Tussock grasses or bunch grasses are a group of grass species in the family Poaceae. They usually grow as singular plants in clumps, tufts, hummocks, or bunches, rather than forming a sod or lawn, in meadows, grasslands, and prairies. As perennial plants, most species live more than one season. Tussock grasses are often found as forage in pastures and ornamental grasses in gardens. Many species have long roots that may reach or more into the soil, which can aid slope stabilization, erosion control, and soil porosity for precipitation absorption. Also, their roots can reach moisture more deeply than other grasses and annual plants during seasonal or climatic droughts. The plants provide habitat and food for insects (including Lepidoptera), birds, small animals and larger herbivores, and support beneficial soil mycorrhiza. The leaves supply material, such as for basket weaving, for indigenous peoples and contemporary artists. Tussock and bunch grasses occur in almost any habitat ...

Nothofagus
''Nothofagus'', also known as the southern beeches, is a genus of 43 species of trees and shrubs native to the Southern Hemisphere in southern South America (Chile, Argentina) and Australasia (east and southeast Australia, New Zealand, New Guinea, and New Caledonia). The species are ecological dominants in many temperate forests in these regions. Some species are reportedly naturalised in Germany and Great Britain. The genus has a rich fossil record of leaves, cupules, and pollen, with fossils extending into the late Cretaceous period and occurring in Australia, New Zealand, Antarctica, and South America. Description The leaves are toothed or entire, evergreen or deciduous. The fruit is a small, flattened or triangular nut, borne in cupules containing one to seven nuts. Reproduction Many individual trees are extremely old, and at one time, some populations were thought to be unable to reproduce in present-day conditions where they were growing, except by suckering ( clonal rep ...

Coprolite
A coprolite (also known as a coprolith) is fossilized feces. Coprolites are classified as trace fossils as opposed to body fossils, as they give evidence for the animal's behaviour (in this case, diet) rather than morphology. The name is derived from the Greek words κόπρος (''kopros'', meaning "dung") and λίθος (''lithos'', meaning "stone"). They were first described by William Buckland in 1829. Before this, they were known as "fossil fir cones" and "bezoar stones". They serve a valuable purpose in paleontology because they provide direct evidence of the predation and diet of extinct organisms. Coprolites may range in size from a few millimetres to over 60 centimetres. Coprolites, distinct from ''paleofeces'', are fossilized animal dung. Like other fossils, coprolites have had much of their original composition replaced by mineral deposits such as silicates and calcium carbonates. Paleofeces, on the other hand, retain much of their original organic composition ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crop (anatomy)
A crop (sometimes also called a croup or a craw, ingluvies, or sublingual pouch) is a thin-walled expanded portion of the alimentary tract used for the storage of food prior to digestion. This anatomical structure is found in a wide variety of animals. It has been found in birds, and in invertebrate animals including gastropods (snails and slugs), earthworms, leeches, and insects. Insects Cropping is used by bees to temporarily store nectar of flowers. When bees "suck" nectar, it is stored in their crops. Other Hymenoptera also use crops to store liquid food. The crop in eusocial insects, such as ants, has specialized to be distensible, and this specialization enables important communication between colonial insects through trophallaxis. The crop can be found in the foregut of insects. Birds In a bird's digestive system, the crop is an expanded, muscular pouch near the gullet or throat. It is a part of the digestive tract, essentially an enlarged part of the esophagus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Island
The South Island, also officially named , is the larger of the two major islands of New Zealand in surface area, the other being the smaller but more populous North Island. It is bordered to the north by Cook Strait, to the west by the Tasman Sea, and to the south and east by the Pacific Ocean. The South Island covers , making it the world's 12th-largest island. At low altitude, it has an oceanic climate. The South Island is shaped by the Southern Alps which run along it from north to south. They include New Zealand's highest peak, Aoraki / Mount Cook at . The high Kaikōura Ranges lie to the northeast. The east side of the island is home to the Canterbury Plains while the West Coast is famous for its rough coastlines such as Fiordland, a very high proportion of native bush and national parks, and the Fox and Franz Josef Glaciers. The main centres are Christchurch and Dunedin. The economy relies on agriculture and fishing, tourism, and general manufacturing and services. ...

Euryapteryx Curtus
The broad-billed, stout-legged moa or coastal moa (''Euryapteryx curtus'') is an extinct species of moa. These moa lived in both the North and the South Islands of New Zealand, and on Stewart Island. Its habitat was in the lowlands (duneland, forest, shrubland, and grassland). It was a ratite and a member of the lesser moa family. The ratites are flightless birds with a sternum without a keel. They also have a distinctive palate. The origin of these birds is becoming clearer as it is now believed that early ancestors of these birds were able to fly and flew to the southern areas that they have been found in. As of 2006, half of all complete or mostly complete moa eggs in museum collections are likely broad-billed moa specimens. Of the specimens traditionally given the name ''Euryapteryx gravis'', the eggs has an average length of 205mm and width of 143mm, while the group traditionally assigned to the name ''Euryapteryx curtus'' had an average length of 122mm and width of 94mm ...
