Chelonoidis Nigra Porteri
''Chelonoidis'' is a genus of turtles in the tortoise family erected by Leopold Fitzinger in 1835. They are found in South America and the Galápagos Islands, and formerly had a wide distribution in the West Indies. The multiple subspecies of the Galápagos tortoise are among the largest extant terrestrial chelonians. Giant members of the genus, such as Lutz's giant tortoise (''C. lutzae'') were also present in mainland South America and the West Indies during the Pleistocene. Taxonomy They were formerly assigned to ''Geochelone'', but a 2006 genetic analysis indicated that they were actually most closely related to hingeback tortoises. However, a more recent genetic analysis of mtDNA has found that they are actually most closely related to the lineage containing ''Centrochelys'' and ''Geochelone''. Their ancestors apparently floated across the Atlantic from Africa to South America in the Oligocene. This crossing was made possible by their ability to float with their head ...

Leopold Fitzinger
Leopold Joseph Franz Johann Fitzinger (13 April 1802 – 20 September 1884) was an Austrian zoologist. Fitzinger was born in Vienna and studied botany at the University of Vienna under Nikolaus Joseph von Jacquin. He worked at the Vienna Naturhistorisches Museum between 1817, when he joined as a volunteer assistant, and 1821, when he left to become secretary to the provincial legislature of Lower Austria; after a hiatus he was appointed assistant curator in 1844 and remained at the Naturhistorisches Museum until 1861. Later he became director of the zoos of Munich and Budapest. In 1826 he published ''Neue Classification der Reptilien'', based partly on the work of his friends Friedrich Wilhelm Hemprich and Heinrich Boie Heinrich Boie (4 May 1794, Meldorf, Holstein – 4 September 1827, Bogor, West Java, Indonesia) was a German zoologist. He was the brother of Friedrich Boie. In the field of herpetology they described 49 new species of reptiles and severa .... In 18 ...

Reptile Database
The Reptile Database is a scientific database that collects taxonomic information on all living reptile species (i.e. no fossil species such as dinosaurs). The database focuses on species (as opposed to higher ranks such as families) and has entries for all currently recognized ~13,000 species and their subspecies, although there is usually a lag time of up to a few months before newly described species become available online. The database collects scientific and common names, synonyms, literature references, distribution information, type information, etymology, and other taxonomically relevant information. History The database was founded in 1995 as EMBL Reptile Database when the founder, Peter Uetz, was a graduate student at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany. Thure Etzold had developed the first web interface for the EMBL DNA sequence database which was also used as interface for the Reptile Database. In 2006 the database moved to The Inst ...

Turtle Taxonomy Working Group
The Turtle Taxonomy Working Group (TTWG) is an informal working group of the IUCN/SSC Tortoise and Freshwater Turtle Specialist Group (TFTSG). It is composed of a number of leading turtle Taxonomy (biology), taxonomists, with varying participation by individual participants over the years, some dropping out and others joining. The TTWG has produced an annual checklist of living and recently extinct turtles since 2007, deliberates on proposed changes to turtle taxonomy, and describes its consideration whether to accept, reject, or suspend adoption of proposed changes in a series of annotations to the checklist. Recent versions of the checklist have included full primary synonymies and citations to all original descriptions of recent turtle taxa, as well as CITES and IUCN Red List status of each species as applicable.

Turks And Caicos Islands
The Turks and Caicos Islands (abbreviated TCI; and ) are a British Overseas Territory consisting of the larger Caicos Islands and smaller Turks Islands, two groups of tropical islands in the Lucayan Archipelago of the Atlantic Ocean and northern West Indies. They are known primarily for tourism and as an offshore financial centre. The resident population in July 2021 was put at 57,196, making it the third-largest of the British overseas territories by population. The islands are southeast of Mayaguana in the Bahamas island chain and north of the island of Hispaniola (Haiti and the Dominican Republic). Grand Turk (Cockburn Town), the capital since 1766, is situated on Grand Turk Island about east-southeast of Miami, United States. They have a total land area of . The islands were inhabited for centuries by indigenous peoples. The first recorded European sighting of them was in 1512. In subsequent centuries, they were claimed by several European powers, with the British ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bahamas
The Bahamas (), officially the Commonwealth of The Bahamas, is an island country within the Lucayan Archipelago of the West Indies in the North Atlantic. It takes up 97% of the Lucayan Archipelago's land area and is home to 88% of the archipelago's population. The archipelagic state consists of more than 3,000 islands, cays, and islets in the Atlantic Ocean, and is located north of Cuba and northwest of the island of Hispaniola (split between the Dominican Republic and Haiti) and the Turks and Caicos Islands, southeast of the U.S. state of Florida, and east of the Florida Keys. The capital is Nassau on the island of New Providence. The Royal Bahamas Defence Force describes The Bahamas' territory as encompassing of ocean space. The Bahama Islands were inhabited by the Lucayans, a branch of the Arawakan- speaking Taíno, for many centuries. Christopher Columbus was the first European to see the islands, making his first landfall in the "New World" in 1492 when h ...

Chelonoidis Alburyorum
''Chelonoidis alburyorum'' is an extinct species of land tortoise that lived from the late Pleistocene to around 1400 CE. The species was discovered and described by Richard Franz and Shelley E. Franz, the findings being published in 2009. Name The specific epithet, ''alburyorum'', is in honor of Bahamian naturalist Nancy Ann Albury. Fossil The shell of ''C. alburyorum'' was 47 cm (19 inches) in length. Fossils of the species were discovered in Sawmill Sink, a blue hole. Other sites where ''C. alburyorum'' fossils have been found include cave systems and an inland deep blue sink hole. All fossils of ''C. alburyorum'' have been found in the Bahamas. Extinction ''C. alburyorum'' was the last-surviving of the West Indian ''Chelonoidis'', persisting up to 1170 CE on the Abacos, up to 1200 CE on Grand Turk, and up to 1400 CE on the Middle Caicos Middle Caicos is the largest island in the Turks and Caicos Islands. To the west, it is separated from North Caicos by Juniper H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basal (phylogenetics)
In phylogenetics, basal is the direction of the ''base'' (or root) of a rooted phylogenetic tree or cladogram. The term may be more strictly applied only to nodes adjacent to the root, or more loosely applied to nodes regarded as being close to the root. Note that extant taxa that lie on branches connecting directly to the root are not more closely related to the root than any other extant taxa. While there must always be two or more equally "basal" clades sprouting from the root of every cladogram, those clades may differ widely in taxonomic rank, species diversity, or both. If ''C'' is a basal clade within ''D'' that has the lowest rank of all basal clades within ''D'', ''C'' may be described as ''the'' basal taxon of that rank within ''D''. The concept of a 'key innovation' implies some degree of correlation between evolutionary innovation and diversification. However, such a correlation does not make a given case predicable, so ancestral characters should not be imputed to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yellow-footed Tortoise
The yellow-footed tortoise (''Chelonoidis denticulatus''), also known as the Brazilian giant tortoise, commonly referred to as the Brazilian giant turtle, or more commonly, the big turtle, is a species of tortoise in the family Testudinidae and is closely related to the red-footed tortoise (''C. carbonarius''). It is found in the Amazon Basin of South America. The species name has often been misspelled as ''denticulata'', an error introduced in the 1980s when ''Chelonoidis'' was elevated to genus and mistakenly treated as feminine, an error recognized and fixed in 2017. With an average length of 40 cm (15.75 in) and the largest known specimen at 94 cm (37 in), this is the sixth-largest tortoise species on Earth, after the Galapagos tortoise, the Aldabra tortoise, the African spurred tortoise (''Geochelone sulcata'', typical size 76 cm (30 in)), the leopard tortoise (''Stigmochelys pardalis''), and the Asian forest tortoise (''Manouria emys emys'', ty ...

Red-footed Tortoise
The red-footed tortoise (''Chelonoidis carbonarius'') is a species of tortoise from northern South America. These medium-sized tortoises generally average as adults, but can reach over . They have dark-colored, loaf-shaped carapaces (back shell) with a lighter patch in the middle of each scute (scales on the shell), and dark limbs with brightly colored scales that range from pale yellow to dark red. Recognized differences are seen between red-footed tortoises from different regions. They are closely related to the yellow-footed tortoise (''C. denticulatus'') from the Amazon Basin. They are popularly kept as pets, and over-collection has caused them to be vulnerable to extinction.The species name has often been misspelled as ''carbonaria'', an error introduced in the 1980s when ''Chelonoidis'' was elevated to genus and mistakenly treated as feminine, an error recognized and fixed in 2017. Their natural habitat ranges from savannah to forest edges around the Amazon Basin. They ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
