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] |
Basilemys
''Basilemys'' ("king turtle" in Greek) is a large, terrestrial Nanhsiungchelyidae, nanhsiungchelyid turtle from the Upper Cretaceous of North and Central America. ''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. In an analysis made by Sukhanov et al. on a nansiunghelyid turtle from the Upper Cretaceous of Mongolia, it was demonstrated that Asian nanhsiungchelyids gave rise to the North American nanhsiungchelyids. Amongst nanhsiungchelyids, ''Basilemys'' is considered to be most similar to tortoises. Many paleontologists have described the behaviors of ''Basilemys'' to likely be comparable to that of tortoises, due to living in terrestrial habitats and consuming tough plants. ''Basilemys'' is easily distinguishable from other fossil turtles due to how thick its shell is, the intricate sculpture of rows of triangular tubercles separated by pits, and i ...

Nanhsiungchelys
''Nanhsiungchelys'' is a trionychoid turtle from the Upper Cretaceous of Nanhsiung, China. Its genus is derived from the location where it was found, Nanhsiung and the greek word "χελωνα" (chelona), which means turtle. Therefore, ''Nanhsiungchelys'' means "turtle from Nanxiong". ''Nanhsiungchelys'' has been found in rocks dating to the Maastrichtian of Asia and North America. A second species, ''N. yangi'', was described in 2023 on the basis of a skull, mandible, and anterior portion of the carapace A carapace is a dorsal (upper) section of the exoskeleton or shell in a number of animal groups, including arthropods, such as crustaceans and arachnids, as well as vertebrates, such as turtles and tortoises.

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 more recent 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 ''cre ..., and has thus far been exclusively found in Mongolia.

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

Royal Tyrrell Museum
The Royal Tyrrell Museum of Palaeontology (RTMP; 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 Tyrrell, 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 Royal Alberta Museum, 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 ex ...
