Nanhsiungchelyid
Nanhsiungchelyidae ( or ) 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 The Adocidae are an extinct family of aquatic and omnivorous turtle Turtles are an order of reptiles known as Testudines, characterized by a special shell developed mainly from their ribs.

Basilemys
''Basilemys'' () is a large, terrestrial trionychoid turtle from the Upper Cretaceous. In Greek, the word "Basil" means royal or kingly and the word "Emys" means turtle. Therefore, ''Basilemys'' means King Turtle. ''Basilemys'' has been found in rocks dating to the Campanian and Maastrichtian subdivisions of the Late Cretaceous and is considered to be the largest terrestrial turtle of its time. ''Basilemys'' has solely been found in North America. The family Nanhsiungchelyidae, which is the family ''Basilemys'' belongs to, made its first appearance in the Lower Cretaceous, in what we now call Asia. Because of ''Basilemys,'' we know that this family appeared in North America in the Upper Cretaceous. It is possible that ''Basilemys'' and other nanhsiungchelyids are immigrants from Asia. They might have arrived in North America by passing through what we now call the Bering Strait somewhere during the Cretaceous.

Jiangxichelys
''Jiangxichelys'' ( or ) is an extinct genus of nanhsiungchelyid turtle which existed in Ganzhou, Jiangxi Province, China during the latest Cretaceous epoch. It was first named by Haiyan Tong and Jinyou Mo in 2010 and the type species is ''Jiangxichelys ganzhouensis''. It was an aquatic omnivore An omnivore () is an animal that has the ability to eat and survive on both plant and animal matter.

Kharakhutulia
''Kharakhutulia'' () is a genus of nanhsiungchelyid turtle from the Upper Cretaceous. Its genus name refers to the location where it was found, namely the Khara Khutul fossil locality of Mongolia. Its species name refers to the scientist who collected the holotype specimen: Dr. Nikolai N. Kalandadze. ''Kharakhutulia'' has been found in rocks dating to the Cenomanian and Turonian subdivisions of the Late Cretaceous The Late Cretaceous (100.5–66 Ma) is the younger of two epochs into which the Cretaceous Period is divided in the geologic time scale. Rock strata from this epoch form the Upper Cretaceous Series. The Cretaceous is named after ''creta'', the ..., and has thus far been exclusively found in Mongolia.

Royal Tyrrell Museum
The Royal Tyrrell Museum of Palaeontology (RTMP, and often referred to as the Royal Tyrrell Museum) is a palaeontology museum and research facility in Drumheller, Alberta, Canada. The museum was named in honour of Joseph Burr Tyrrell, and is situated within a designed by BCW Architects at Midland Provincial Park. Efforts to establish a palaeontology museum were announced by the provincial government in 1981, with the palaeontology program of the Provincial Museum of Alberta spun-off to help facilitate the creation of a palaeontology museum. After four years of preparation, the Tyrrell Museum of Palaeontology was opened in September 1985. The museum was later renamed the Royal Tyrrell Museum of Palaeontology in June 1990, following its bestowal of the title "royal" from Queen Elizabeth II. The museum's building was expanded twice in the 21st century. The first expansion was designed by BCW Architects, and was completed in 2003; while the second expansion was designed by Kasian Arch ...

Cretaceous Turtles
The Cretaceous ( ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin ''creta'', "chalk", which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation ''Kreide''. The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now- extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was ice free, and forests extended to the poles. During this time, new groups of mammals and birds appeared. During the Early Cretaceous, flowering plants appeared and began to rapidly diversify, becoming the dominant group of plants across the Earth b ...

Trionychia
Trionychia is a superfamily of turtles which encompasses the species that are commonly referred to as softshelled turtles as well as some others. 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. Systematics Except for those not assigned to a family, only living genera are listed here. *Family Carettochelyidae ** Subfamily Carettochelyinae *** Genus '' Carettochelys'' *Pan-Trionychidae ** Family PlastomenidaeOne or more basal lineages formerly believed to be a distinct family (fossil) ** Family Trionychidae ***Subfamily Cyclanorbinae **** Genus '' Cyclanorbis'' **** Genus '' Cycloderma' ...

Adocus
''Adocus'' is an extinct genus of aquatic turtles belonging to the family Adocidae. ''Adocus'' was once considered to belong to the family Dermatemyidae. Description Species of the genus ''Adocus'' had flattened and smoothly contoured shells with horny sculptured plates. The shells could reach a length of about 80 cm. 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.

Adocidae
The Adocidae are an extinct family of aquatic and omnivorous 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 t ...s. 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, Kazakhstan, Kyrgyzstan, Laos, Mexico, Mongolia, Tajikistan, Thailand, United States and Uzbekistan.
