Mascarene Teal
The Mascarene teal (''Anas theodori''), also known as Sauzier's teal and Mauritian duck, is an extinct dabbling duck that formerly occurred on the islands of Mauritius and Réunion. Taxonomy The reports of Bernardin and (1710) Boucher are puzzling insofar as that they mention both geese, ''sarcelles'' (teals, this species) as well as ''canards'' (ducks, larger than ''sarcelles'') as occurring or having occurred on Réunion. It is possible that a carpometacarpus bone apparently of an ''Aythya'' diving duck is referrable to these ''canards''. If so, these birds were probably related to the Madagascar pochard, of which only small numbers are known to remain. Earlier, it was proposed that Meller's duck, also from Madagascar, is the closest living relative of ''A. theodori'', but as more remains of the latter were unearthed this appears far less likely. Apart from a few, brief descriptions, not much is known about the bird in life, but its habits probably did not differ signif ...

Subfossils
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the absol ...

Bird Extinctions Since 1500
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. Bird ...

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] |

Anas
''Anas'' is a genus of dabbling ducks. It includes the pintails, most teals, and the mallard and its close relatives. It formerly included additional species but following the publication of a molecular phylogenetic study in 2009 the genus was split into four separate genera. The genus now contains 31 living species. The name ''Anas'' is the Latin for "duck". Systematics The genus ''Anas'' was introduced by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae''. ''Anas'' is the Latin word for a duck. The genus formerly included additional species. In 2009 a large molecular phylogentic study was published that compared mitochondrial DNA sequences from ducks, geese and swans in the family Anatidae. The results confirmed some of the conclusions of earlier smaller studies and indicated that the genus as then defined was non-monophyletic. Based on the results of this study, ''Anas'' was split into four proposed monophyletic genera with five spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Père Bernardin
A name suffix, in the Western English-language naming tradition, follows a person's full name and provides additional information about the person. Post-nominal letters indicate that the individual holds a position, educational degree, accreditation, office, or honor (e.g. " PhD", "CCNA", "OBE"). Other examples include generational designations like "Sr." and "Jr." and "I", "II", "III", etc. Another used is Sñr (Spanish for Mr). Post-nominal letters Academic Academic suffixes indicate the degree earned at a college or university. These include bachelor's degrees (AB, BA, BA (Hons), BS, BE, BFA, BTech, LLB, BSc, etc.), master's degrees ( MA, MS, MFA, LLM, MLA, MBA, MSc., MEng etc.), professional doctorates ( JD, MD, DO, PharmD, DMin., etc.), and academic doctorates (PhD., EdD., DPhil, DBA., LLD, EngD, etc.) In the case of doctorates, normally either the prefix (e.g. "Dr" or "Atty") or the suffix (see examples above) is used, but not both. In the United States, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jean Feuilley
Jean Feuilley was a pilot engineer and cartographer who was sent to Réunion by the French East India Company to investigate the possibility of agricultural and marine exploitation. He arrived in the island in 1704 and the following year returned to France. His "Mission à l’île Bourbon du sieur Feuilley en 1704" (published 1705) contains among other things descriptions of now-extinct bird species, like the Réunion kestrel and the Réunion ibis The Réunion ibis or Réunion sacred ibis (''Threskiornis solitarius'') is an extinct species of ibis that was endemic to the volcanic island of Réunion in the Indian Ocean. The first subfossil remains were found in 1974, and the ibis was firs .... References French cartographers French East India Company French engineers French male writers {{France-engineer-stub ...

Roelof Deodati
Roelof Diodati (Dordrecht, 28 July 1658 – Batavia, 10 March 1723) was a governor of Dutch Mauritius in the late 17th century. Life Diodati was from Swiss-Italian descent. His grandfather was Jean Diodati, a theologian, who translated the Bible into Italian. His father, born in Geneva, became a pastor of the Walloon church in Leiden in 1651. It is not obvious Rodolfo Diodati was one of a twin. Both brothers took service at the Dutch East India Company. He became an accountant at the Cape from 1686 and then a merchant. He was appointed as governor of Mauritius from 1692-1703. In 1693 he had to deal with François Leguat. In 1695, a big hurricane devastated the island, several of the Burghers lost all theirs crops, many left the island. Diodati seems to have been appointed in Suratte. Then he shifted to Batavia and he became a merchant and accountant on 4 January 1707. In 1709 he married Catharina Zaaiman, born on Dutch Mauritius. Her grandmother was Eva, a Khoikhoi interpret ...

Alopochen Kervazoi And Anas Theodori
''Alopochen'' is a genus of the bird family Anatidae, part of the subfamily Tadorninae along with the shelducks. It contains one extant species, the Egyptian goose (''Alopochen aegyptiaca''), and two or three species which became extinct in the last 1000 years or so. The Egyptian goose is native to mainland Africa, and the extinct species are from Madagascar and the Mascarene Islands. mtDNA cytochrome ''b'' sequence data suggest that the relationships of ''Alopochen'' to '' Tadorna'' need further investigation. Species * Egyptian goose, ''Alopochen aegyptiaca'' The extinct species of the genus are: * Malagasy shelduck or Madagascar shelduck, ''Alopochen sirabensis'' (Andrews 1897) (may be subspecies of ''A. mauritiana'') – Madagascar, prehistoric: see Late Quaternary prehistoric birds * Mauritius sheldgoose, ''Alopochen mauritiana'' (Newton & Gadow 1893)– Mauritius Mauritius ( ; french: Maurice, link=no ; mfe, label= Mauritian Creole, Moris ), officially the Re ...
