Kueichowlepis is an extinct genus of placoderm fish, which lived during the Devonian period of East Asia. [1] [2]
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.
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.

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.
The Deseadan age is a period of geologic time within the Oligocene epoch of the Paleogene to the Early Miocene epoch of the Neogene, used more specifically within the SALMA classification of South America. It follows the Tinguirirican and precedes the Colhuehuapian age.
The Laventan age is a period of geologic time within the Middle Miocene epoch of the Neogene, used more specifically within the SALMA classification in South America. It follows the Colloncuran and precedes the Mayoan age.
The Huayquerian age is a period of geologic time within the Late Miocene epoch of the Neogene, used more specifically within the SALMA classification. It follows the Mayoan and precedes the Montehermosan age.
Brasilodontidae is an extinct family of cynodonts closely related to mammals. In life, brasilodontids were small-bodied and probably insectivorous. Most brasilodontid remains are known from the Late Triassic of Brazil, having been found in the municipalities of Candelária and Faxinal do Soturno. The species Brasilodon quadrangularis, is known only from Paleorrota. Brasilodonts are also known from Argentina. An Indian species of cynodont called Panchetocynodon damodarensis has also been assigned to Brasilodontidae. It dates back to the Early Triassic, tremendously extending the temporal range of the family.
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.
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.
