Mauritius Night Heron
The Mauritius night heron (''Nycticorax mauritianus'') is an extinct night heron species from Mauritius. It is only known by seven subfossil bone remains consisted of cranium, pelvis, coracoid, ulna, radius, and tarsometatarsus found in Mare aux Songes. Only the coracoid and the tarsometatarsus are left today. It was scientifically described in 1893 by Edward Newton and Hans Gadow from the Cambridge University. Newton and Gadow measured the tarsometatarsus with 81 to 87 mm.Greenway, James C.

Edward Newton
Sir Edward Newton (10 November 1832 – 25 April 1897) was a British colonial administrator and ornithologist. He was born at Elveden Hall, Suffolk the sixth and youngest son of William Newton, MP. He was the brother of ornithologist Alfred Newton. He graduated from Magdelene College, Cambridge in 1857 and was one of the twenty founding members of the British Ornithologists' Union. Newton was the Colonial Secretary for Mauritius from 1859 to 1877. From there he sent his brother a number of specimens, including the dodo and the Rodrigues solitaire, both already extinct. In 1878, Newton initiated the first laws anywhere specifically designed to protect indigenous land birds from persecution. Edward was later Colonial Secretary and Lieutenant-Governor of Jamaica (1877–1883). He married Mary Louisa Cranstoun, daughter of W.W.R. Kerr in 1869. She died the following year. He is commemorated in the binomial of the Malagasy kestrel, ''Falco newtoni''. '' Phelsuma edwardnew ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Extinct Animals Of Mauritius
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, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Birds Of Mauritius
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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nycticorax
''Nycticorax'' is a genus of night herons. The name ''Nycticorax'' means "night raven" and derives from the Ancient Greek νύκτος, ''nuktos'' "night" and κοραξ, ''korax'', "raven". It refers to the largely nocturnal feeding habits of this group of birds, and the croaking crow-like call of the best known species, the black-crowned night heron. These are medium-sized herons which often are migratory in the colder parts of their ranges. Adults are short-necked, relatively short-legged and stout herons; the two extant species both have a black crown and a whitish belly, while the wings, chest, neck and auriculars are grey or rufous depending on the species. Young birds are brown, flecked with white and grey, and are quite similar to each other in the extant species. At least some of the extinct Mascarenes taxa appear to have retained this juvenile plumage in adult birds. Night herons nest in colonies on platforms of sticks in a group of trees, or on the ground in pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

François Leguat
François Leguat (1637/1639 – September 1735) was a French explorer and naturalist. He was one of a small group of male French Protestant refugees who in 1691 settled on the then uninhabited island of Rodrigues in the western Indian Ocean. The colonists became discontented with their life on the island and after a stay of two years managed to escape to Mauritius in a small boat. Leguat arrived back in Europe in June 1698 and wrote a book recounting his adventures which was published in 1708. In his book Leguat describes several species of birds and tortoises that were endemic to Rodrigues but are now extinct. Life François Leguat was a French Huguenot originating from the Province of Bresse, now part of the department of Ain, who fled to Holland in 1689 after the revocation of the Edict of Nantes in 1685. Marquis Henri du Quesne had published a book giving a glowing description of the island of Réunion and, with the cooperation of the Dutch East India Company, was ...

Mare Aux Songes
The Mare aux Songes () swamp is a lagerstätte located close to the sea in south eastern Mauritius. Many subfossils of recently extinct animals have accumulated in the swamp, which was once a lake, and some of the first subfossil remains of dodos were found there. History In 1865, government schoolmaster at Mahébourg, George Clark, finally found an abundance of subfossil dodo bones in the swamp of Mare aux Songes in Southern Mauritius, after searching for thirty years, having been inspired by Strickland & Melville's monograph about the bird. In 1866, Clark explained his procedure to The Ibis, an ornithology journal: Remains of over 300 dodos were found in the swamp, but only very few skull and wing bones among them, which may be explained by the upper bodies having been washed away or scavenged while the lower body was trapped, which is similar to the way many moa remains have been found in New Zealand marshes. In 1889, Théodor Sauzier was commissioned to find more dodo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hans Gadow
Hans Friedrich Gadow (8 March 1855 – 16 May 1928) was a German-born ornithologist who worked in Britain. His work on the classification of birds based on anatomical and morphological characters was influential and made use of by Alexander Wetmore in his classification of North American birds. Gadow was born in Stary Kraków (Pomerania), the son of an inspector of the Prussian royal forests. He studied at the universities of Berlin, Jena and Heidelberg. At Jena he studied under Ernst Haeckel and at Heidelberg University under the anatomist Karl Gegenbaur. After graduation he travelled to the Natural History Museum in London in 1880 at the request of Albert Günther, to work on the museum's ''Catalogue of Birds''. Gadow also established the first new sequence of bird orders and families that departed from earlier works in being based on phylogenetic principles based on a comparison of anatomical and morphological features and made use of the studies made by Max Fürbringer.

Tarsometatarsus
The tarsometatarsus is a bone that is only found in the lower leg of birds and some non-avian dinosaurs. It is formed from the fusion of several bones found in other types of animals, and homologous to the mammalian tarsus (ankle bones) and metatarsal bones (foot). Despite this, the tarsometatarsus of birds is often referred to as just the shank, tarsus or metatarsus. Tarsometatarsal fusion occurred in several ways and extents throughout bird evolution. Specifically, in Neornithes (modern birds), although the bones are joined along their entire length, the fusion is most thorough at the distal (metatarsal) end. In the Enantiornithes, a group of Mesozoic avialans, the fusion was complete at the proximal (tarsal) end, but the distal metatarsi were still partially distinct. While these fused bones are best known from birds and their relatives, avians are neither the only group nor the first to possess tarsometatarsi. In a remarkable case of parallel evolution, they were also pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
