Chelus Columbiana
''Chelus'' is a genus of freshwater turtles found in South America. Formerly considered to be a monotypic genus, it now consists of two species after '' Chelus orinocensis'' was identified in 2020 from a genomic analysis. Species *''Chelus fimbriatus Matamata () is a town in Waikato, New Zealand.

Turtle
Turtles are an order of reptiles known as Testudines, characterized by a special 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 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 carapace, while the underside is the flatter plastron or belly-plate. Its outer surface is covered in scales made of keratin, the material of hair, horns, and claws. The carapace bones develop from ribs that grow sideways and develop into broad flat plates th ...

South America
South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere at the northern tip of the continent. It can also be described as the southern subregion of a single continent called America. South America is bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean; North America and the Caribbean Sea lie to the northwest. The continent generally includes twelve sovereign states: Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay, and Venezuela; two dependent territories: the Falkland Islands and South Georgia and the South Sandwich Islands; and one internal territory: French Guiana. In addition, the ABC islands of the Kingdom of the Netherlands, Ascension Island (dependency of Saint Helena, Ascension and Tristan da Cunha, a British Overseas Territory), Bouvet Island ( dependency of Norway), Pa ...

Monotypic Genus
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda.' ...

Chelus Orinocensis
''Chelus orinocensis'' is a freshwater turtle found in South America, primarily in the Orinoco basin. It was split off from '' Chelus fimbriata'' in 2020. Discovery via genomic analysis A genomic analysis of the mata mata was reported in 2020, which showed a deep split between the populations in the Amazon and Orinoco basins. The authors proposed that the Orinoco population be assigned to a new species, ''Chelus orinocensis'', with the Amazon population retaining the ''Chelus fimbriatus Matamata () is a town in Waikato, New Zealand.

Prior to its description as a separate species, observations of distinctive morphological differences had already been noted among specimens in the populations of the Amazon and Orinoco basins.

Chelus Fimbriatus
Matamata () is a town in Waikato, New Zealand. It is located near the base of the Kaimai Ranges, and is a thriving farming area known for Thoroughbred horse breeding and training pursuits. It is part of the Matamata-Piako District, which takes in the surrounding rural areas, as well as Morrinsville and Te Aroha. State Highway 27 and the Kinleith Branch railway run through the town. The town has a population of as of A nearby farm was the location for the Hobbiton Movie Set in Peter Jackson's ''The Lord of the Rings''. The New Zealand government decided to leave the Hobbit holes built on location as tourist attractions. During the period between the filming of '' The Lord of the Rings: The Return of the King'' and '' The Hobbit: An Unexpected Journey'' they had no furniture or props, but could be entered with vistas of the farm viewed from inside them. A "Welcome to Hobbiton" sign has been placed on the main road. In 2011, parts of Hobbiton began to close in preparation for th ...
