List of crurotarsan genera

Last updated

This list of crurotarsans is a comprehensive listing of all genera that have ever been included in the clade Crurotarsi, excluding purely vernacular terms. Under some definitions Crurotarsi includes all archosaurs, but this list excludes archosaur genera that are included in Avemetatarsalia (pterosaurs, nonavian dinosaurs, and birds). The list includes all commonly accepted genera, but also genera that are now considered invalid, doubtful ( nomen dubium ), or were not formally published ( nomen nudum ), as well as junior synonyms of more established names, and genera that are no longer considered crurotarsan. Extinct taxa are denoted with a dagger (†). The list contains 636 names, of which approximately 547 are considered either valid crurotarsan genera or nomina dubia .

Scope and terminology

There is no official, canonical list of crurotarsan genera, but one of the most thorough attempts can be found on the Crurotarsi section of Mikko Haaramo's Phylogeny Archive. That list has been supplemented with the Paleofile listing for Crocodylomorpha.

Naming conventions and terminology follow the International Code of Zoological Nomenclature. Technical terms used include:

<i>Geosaurus</i> Extinct genus of reptiles

Geosaurus is an extinct genus of marine crocodyliform within the family Metriorhynchidae, that lived during the Late Jurassic and the Early Cretaceous. Geosaurus was a carnivore that spent much, if not all, its life out at sea. No Geosaurus eggs or nests have been discovered, so little is known of the reptile's lifecycle, unlike other large marine reptiles of the Mesozoic, such as plesiosaurs or ichthyosaurs which are known to give birth to live young out at sea. Where Geosaurus mated, whether on land or at sea, is currently unknown. The name Geosaurus means "Mother of Giants lizard", and is derived from the Greek Ge- and σαῦρος -sauros ("lizard"). The name Geosaurus was established by the French naturalist Georges Cuvier in 1824.

Cricosaurus is an extinct genus of marine crocodyliforms of the Late Jurassic. belonging to the family Metriorhynchidae. The genus was established by Johann Andreas Wagner in 1858 for three skulls from the Tithonian of Germany. The name Cricosaurus means "Ring lizard", and is derived from the Greek Krikos- ("ring") and σαῦρος -sauros ("lizard"). It was a relatively small reptile, with C. suevicus and C. araucanensis measuring 2 m (6.6 ft) and 3.2 m (10 ft) in total body length, respectively.
