This list of ichthyosauromorphs is a comprehensive listing of all genera that have ever been included in the clade Ichthyosauromorpha, excluding purely vernacular terms.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 ...
This list of ichthyosauromorph type specimens is a list of fossils serving as the official standard-bearers for inclusion in the species and genera of the reptile clade Ichthyosauromorpha (Hupehsuchia included).
The Ichthyosauromorpha are an extinct clade of Mesozoic marine reptiles consisting of the Ichthyosauriformes and the Hupehsuchia. The node clade Ichthyosauromorpha was first defined by Ryosuke Motani et al. in 2014 as the group consisting of the last common ancestor of Ichthyosaurus communis and Hupehsuchus nanchangensis , and all its descendants.
The Ichthyosauriformes are a group of marine reptiles, belonging to the Ichthyosauromorpha, that lived during the Mesozoic.. The stem clade Ichthyosauriformes was in 2014 defined by Ryosuke Motani and colleagues as the group consisting of all ichthyosauromorphs that are more closely related to Ichthyosaurus communis than to Hupehsuchus nanchangensis.

However, more recent studies have shown further support for a monophyletic clade between Ichthyosauromorpha, Sauropterygia, and Thalattosauria as a massive marine clade of aquatic archosauromorphs originating in the Late Permian and diversifying in the Early Triassic. [47] [48] [49]
L. tenuirostris, Royal Ontario Museum Life restoration. Leptonectes is a genus of ichthyosaur that lived in the Late Triassic to Early Jurassic (Rhaetian - Pliensbachian). Fossils have been found in Belgium, Germany, Spain and the United Kingdom.

Ichthyosaurus was the first complete fossil to be discovered in the early 19th century by Mary Anning in England; [9] the holotype of I. communis, no coll. number given, [10] was a fairly complete specimen discovered by Mary and Joseph Anning around 1814 in Lyme ...
