Cyrtoclymeniaceae was an extinct superfamily of ammonites that existed during the Devonian. [1] [2]
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.
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.
Brevidorsum is an extinct genus of dissorophoidean euskelian temnospondyl within the family Dissorophidae.
Batrachosuchoides is an extinct genus of prehistoric amphibian from the Early Triassic of Russia. It was found in the Baskunchakskaia Series and the Lestanshorskaya Svita.
Batrachosaurus is an extinct genus of prehistoric brachyopoid amphibian that lived in Germany during the Middle Triassic (Ladinian). The genus was named by Joseph Fitzinger in 1837 and the type species, B. jaegeri, was named three years later in 1840. It may have been the same animal as Mastodonsaurus.
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.
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.
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.
Coquimbo Formation is a Miocene to Middle Pleistocene sedimentary formation located in Coquimbo Region in Norte Chico, Chile. The lowermost unit belongs to the lower Miocene, with the third-deepest unit dated at 11.9 ± 1.0 Ma. The uppermost unit of the formation is estimated at 1.2 Ma. In the area of Tongoy, the Coquimbo Formation was deposited in an ancient bay that was formed in a graben or half-graben, with a normal fault dipping east. Sea level changes during the Holocene have caused erosion to cut several marine terraces into the formation.
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.
The Hiló Formation is a geological formation of the Altiplano Cundiboyacense, Eastern Ranges of the Colombian Andes. The predominantly shale formation dates to the Middle Cretaceous period; Late Albian to Early Cenomanian epochs and has a measured thickness at its type section of 470 metres (1,540 ft). The fossiliferous formation has provided a great abundance of ammonites and other marine species.
The Normandien Formation is a Triassic-age rock formation located in Free State, South Africa. It is where the fossils of Ericiolacerta, a subtaxa of Ericiolacertidae, were found.
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.
