Adocid
The Adocidae are an extinct family of aquatic and omnivorous turtles. They are freshwater cryptodiran turtles and are mainly known from Cretaceous and Paleogene Asia and North America. Taxonomy Phylogeny modified from Danilov ''et al.'' (2013). ''Yehguia'' is most likely synonymous with ''Sinaspideretes'', and is placed outside of Adocidae here for reasons proposed in Tong, Li & Ouyang (2013). Distribution Species of this genus are present in Oligocene of Kazakhstan, Paleocene of United States, and the Cretaceous of Canada, Japan, South Korea, Kazakhstan, Kyrgyzstan, Laos, Mexico, Mongolia, Tajikistan, Thailand, United States and Uzbekistan.

Adocus Beatus
''Adocus'' is an extinct genus of aquatic turtles belonging to the family Adocidae. Description Species of the genus ''Adocus'' had flattened and smoothly contoured shells with horny sculptured plates. The shells could reach a length of at least for North American species, some species like ''A. kohaku'' had carapace length of . The largest species, ''A. kirtlandius'' had carapace reaching . These large freshwater turtles had an omnivorous diet. They lived from the Late Cretaceous to the Paleocene in North America, but in Asia, they were also present during the Oligocene. Distribution These turtles have been found in Cretaceous to Paleogene of Canada, United States, Mongolia, China, Japan, Kazakhstan, Tajikistan, and Uzbekistan.

Prehistoric Turtles
Prehistory, also called pre-literary history, is the period of human history between the first known use of stone tools by hominins million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared years ago. It took thousands of years for writing systems to be widely adopted, with writing having spread to almost all cultures by the 19th century. The end of prehistory therefore came at different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. It is based on an old conception of history that without written records there could be no history. The most common conception today is that history is based on evidence, however the concept of prehistory hasn't been completely discarded.

Trionychia

The group contains two families, Carettochelyidae, which has only one living species, the pig-nosed turtle (''Carettochelys insculpta'') native to New Guinea and Northern Australia, and Trionychidae, the softshelled turtles, containing numerous species native to Asia, North America and Africa. These families likely diverged during the late Jurassic. The oldest known stem-trionychian is '' Sinaspideretes'' from the Late Jurassic of China.

Sinaspideretes
''Sinaspideretes'' is an extinct genus of turtle from the Late Jurassic of China China, officially the People's Republic of China (PRC), is a country in East Asia. With population of China, a population exceeding 1.4 billion, it is the list of countries by population (United Nations), second-most populous country after ..., probably from the Shaximiao Formation. It is considered the earliest and most basal representative of the Trionychia, and is possibly the oldest known member of Cryptodira. In 2013, it was proposed that this animal and the genus ''Yehguia'' are in fact one and the same. References Sources * ''The Age of Dinosaurs in Russia and Mongolia'' by Michael J. Benton, Mikhail A.

Nanhsiungchelyidae
Nanhsiungchelyidae is an extinct family of land turtles known from Cretaceous deposits in Asia and North America. Nanhsiungchelyids were more terrestrial than many of their contemporaries, and may have gone extinct at the end of the Cretaceous as a result. Classification The name Nanhsiungchelyidae was coined by Yeh in 1966, in the same paper in which the type genus ''Nanhsiungchelys'' was described. The name is derived from the name of the type species, with the suffix of a family, -idae, added to it. Taxonomy According to phylogenetic analyses, Nanhsiungchelyidae is the sister group to Adocidae, and thus both are included within the clade Adocusia. Nanhsiungchelyidae is split into two major clades, one including most of the predominantly Asian species (''Jiangxichelys'', ''Anomalochelys'', etc.) and a clade including only the different species within the genus ''Basilemys''. When looking at recent analyses, it also becomes clear that some of the species of ''Zangerlia'' mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Glyptops And Adocus
''Glyptops'' is an extinct genus of pleurosternid freshwater turtle known from the Late Jurassic of North America. Taxonomy The type species, ''Glyptops plicatulus'', was first described as ''Compsemys plicatulus'' by Edward Drinker Cope on the basis of AMNH 6099, a partial shell from the Late Jurassic (Tithonian) aged Morrison Formation of Colorado. In 1890, a partial skull, YPM 1784 (described from Como Bluff, Wyoming), was named ''Glyptops ornatus'' by Othniel Charles Marsh. Later, Oliver Perry Hay recognized ''Compsemys plicatulus'' and ''Glyptops ornatus'' as being from the same species, hence the new combination ''G. plicatulus''. Another Morrison species of ''Glyptops'', ''G. utahensis'', was described from a complete shell (CM 3412) found at Dinosaur National Monument in Utah. ''Glyptops'' later became a wastebasket taxon to refer to isolated shell fragments with a finely sculpted surface texture. The type of ''Glyptops plicatulus'' was later judged to be a ''nomen dubium ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turtle
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 ...

Peabody Museum Of Natural History
The Peabody Museum of Natural History at Yale University (also known as the Yale Peabody Museum of Natural History or the Yale Peabody Museum) is one of the oldest, largest, and most prolific university natural history museums in the world. It was founded by the philanthropist George Peabody in 1866 at the behest of his nephew Othniel Charles Marsh, an early paleontologist. The museum is best known for the Great Hall of Dinosaurs, which includes a mounted juvenile ''Brontosaurus'' and the mural '' The Age of Reptiles''. The museum also has permanent exhibits dedicated to human and mammal evolution; wildlife dioramas; Egyptian artifacts; local birds and minerals; and Native Americans of Connecticut. In 2020, the Peabody Museum closed for its "first comprehensive renovation in 90 years." It reopened, with more than twice the exhibition space, on March 26, 2024.
