Ninamys was an extinct genus of rodents in the family Aplodontiidae that lived in China during the Oligocene. [1]
Physeter is a genus of toothed whales. There is only one living species in this genus: the sperm whale. Some extremely poorly known fossil species have also been assigned to the same genus including Physeter antiquus from the Pliocene of France, and Physeter vetus from the Quaternary of Georgia. Physeter vetus is very likely an invalid species, as the few teeth that were used to identify this species appear to be identical to those of another toothed whale, Orycterocetus quadratidens.
Pseudorca is a genus with three members which include Pseudorca yokoyamai, Pseudorca yuanliensis and Pseudorca crassidens, of which P. crassidens is the only extant member.
The family Aplodontiidae also known as Aplodontidae, Haplodontiidae or Haploodontini is traditionally classified as the sole extant family of the suborder Protrogomorpha. It may be the sister family of the Sciuridae. There are fossils from the Oligocene until Miocene in Asia, from Oligocene in Europe and from the Oligocene until the present in North America, where there is the only living species: the mountain beaver.
Carcharhinus is the type genus of the family Carcharhinidae, the requiem sharks. One of 12 genera in its family, it contains over half of the species therein. It contains 35 extant and eight extinct species to date, with likely more species yet to be described.
Lissemys is a genus of softshell turtles in the subfamily Cyclanorbinae of the family Trionychidae. The genus is indigenous to southern Asia.
Ailuravus is a genus of prehistoric rodents in the family Ischyromyidae.
Cycloderma is a genus of softshell turtles in the subfamily Cyclanorbinae of the family Trionychidae. The genus is endemic to Africa.
Fossilworks is a portal which provides query, download, and analysis tools to facilitate access to the Paleobiology Database, a large relational database assembled by hundreds of paleontologists from around the world.
The North American land mammal ages (NALMA) establishes a geologic timescale for North American fauna beginning during the Late Cretaceous and continuing through to the present. These periods are referred to as ages or intervals and were established using geographic place names where fossil materials were obtained.
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.
Colubroidea is a superfamily of snakes in the clade Colubroides that include Colubridae and a few other related families. Historically, Colubroidea also included other caenophidian snakes such as cobras and vipers, as these snakes form a clade. However these groups are now divided into several distinct, but related, families. Zaher et al. (2009) proposed to redefine Colubroidea for colubrids and related families, while designating Colubroides as the group containing vipers and cobras as well as colubroids.
Tasbacka is an extinct genus of sea turtle containing several species.
Alienochelys is an extinct genus of sea turtle known from Maastrichian-aged Cretaceous phosphates in Morocco. Its name comes from, unlike other sea turtles, Alienochelys' the jaws being adapted for a powerful crushing pattern, as well as its unusual cranial characteristics. It is a relative of the modern leatherback turtle, as well as the extinct Archelon.
Oligopetes is an extinct genus of rodents in the family of Aplodontiidae, found from Spain to Pakistan during the Oligocene.
Boreostemma is an extinct genus of glyptodonts from northern South America. Fossils assigned to the genus were first described as belonging to Asterostemma from southern South America, but have been placed in the new genus Boreostemma by Carlini et al. in 2008. The type species is B. pliocena. Fossils of Boreostemma have been found in the Honda Group of Colombia, in Peru and Venezuela.
Ilatardia is an extinct genus of bothremydid pleurodiran turtle that was discovered in the Farin Doutchi Formation of Niger. The genus consists solely of type species I. cetiotesta.
Taphrosphys is an extinct genus of bothremydid pleurodiran turtle that was discovered Angola, Morocco and the United States. The genus consists of type species T. sulcatus, T. ppolitoi, T. congolensis, and the dubious T. dares.
Phosphatochelys is an extinct genus of bothremydid pleurodiran turtle that was discovered near Oued Zem, Morocco. The genus consists solely of type species P. tedfordi.
