Nilssonia (turtle)
''Nilssonia'' is a genus of softshell turtles (family Trionychidae) from rivers, streams, ponds, and lakes in South Asia and Burma. In many treatments, it is monotypic, with the single species Burmese peacock softshell (''N. formosa''). However, the supposed other genus of peacock softshells, ''Aspideretes'', is more closely related to ''N. formosa'' than had been believed. They differ only in the neural plates between the first pleural scale pair of the bony carapace, which are fused into one in ''N. formosa'' and unfused in the others. (2007).

Turtle Genera
Turtles are reptiles of the order (biology), order Testudines, characterized by a special turtle shell, shell developed mainly from their ribs. Modern turtles are divided into two major groups, the Pleurodira (side necked turtles) and Cryptodira (hidden necked turtles), which differ in the way the head retracts. There are 360 living and recently extinct species of turtles, including land-dwelling tortoises and freshwater terrapins. They are found on most continents, some islands and, in the case of sea turtles, much of the ocean. Like other Amniote, amniotes (reptiles, birds, and mammals) they breathe air and do not lay eggs underwater, although many species live in or around water. Turtle shells are made mostly of bone; the upper part is the domed Turtle shell#Carapace, carapace, while the underside is the flatter plastron or belly-plate. Its outer surface is covered in scale (anatomy), scales made of keratin, the material of hair, horns, and claws. The carapace bones deve ...

John Anderson (zoologist)
John Anderson (4 October 1833 – 15 August 1900) was a Scottish anatomist and zoologist who worked in India as the curator of the Indian Museum, Calcutta. Early life Anderson was born in Edinburgh, the second son of Thomas Anderson, who worked in the National Bank of Scotland, and his wife Jane Cleghorn. He took an interest in natural history at an early age as did his brother Thomas Anderson, who worked at the Royal Botanic Garden in Calcutta from 1861 to 1863. He went to school at George Square Academy and Hill Street Institution before joining work at the Bank of Scotland. He left the bank to study medicine, and graduated from the University of Edinburgh in 1861. He studied anatomy under John Goodsir and received his MD in 1862 with a gold medal for his thesis in zoology. He was also associated with the founding of the Royal Physical Society which grew out of the Wernerian Society over which he presided. He was appointed to the chair of natural history in the Fre ...

Nilssonia Nigricans
The black softshell turtle or Bostami turtle (''Nilssonia nigricans''), previously placed in genus '' Aspideretes'', is a species of freshwater turtle found in India (Assam and Tripura) and Bangladesh (Chittagong and Sylhet). It was long believed to consist of inbred individuals of the Indian softshell turtle (''A. gangeticus'' or ''N. gangeticus'') or the Indian peacock softshell turtle (''A. hurum'' or ''N. hurum''), but while it is a close relative of the latter, it is a distinct species.Praschag ''et al.'' (2007) In the 1800s, it was believed these turtles were brought from Iran to Chittagong shrine pond by Hazrat Bayezid Bostami. This turtles that he had brought to this pond were treated as sacred and respected by the public. It was also believed by following local tales related to the turtle, about the turtles once being Jinns (a mythological creature in Islam). Previously declared extinct by the International Union for Conservation of Nature in 2002, these turtles were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Georges Cuvier
Jean Léopold Nicolas Frédéric, baron Cuvier (23 August 1769 – 13 May 1832), known as Georges Cuvier (; ), was a French natural history, naturalist and zoology, zoologist, sometimes referred to as the "founding father of paleontology". Cuvier was a major figure in natural sciences research in the early 19th century and was instrumental in establishing the fields of comparative anatomy and paleontology through his work in comparing living animals with fossils. Cuvier's work is considered the foundation of vertebrate paleontology, and he expanded Linnaean taxonomy by grouping classes into phylum, phyla and incorporating both fossils and living species into the classification. Cuvier is also known for establishing extinction as a fact—at the time, extinction was considered by many of Cuvier's contemporaries to be merely controversial speculation. In his ''Essay on the Theory of the Earth'' (1813) Cuvier proposed that now-extinct species had been wiped out by periodic catastr ...
