Ichthyosauromorph genera

Eretmorhipis (meaning "oar fan" from the Greek wikt:ἐρετμόν|, "oar", and wikt:ῥιπίς|, "fan") is an extinct genus of hupehsuchian marine reptiles from the Early Triassic of China. It is currently known from two specimens that were discovered in an exposure of the Jialingjiang Formation in Yuan'an County, Hubei, and referred to the newly named species Eretmorhipis carrolldongi in 2015.

Macgowania is an extinct genus of parvipelvian ichthyosaur known from British Columbia of Canada. It was a small ichthyosaur around in total body length.

Protoichthyosaurus is a genus of ichthyosaur from the early Jurassic of southern England and possibly Switzerland. Two species are known, P. prostaxalis—the type species, named by Appleby in 1979—and P. applebyi. A third species, P. prosostealis, was named by Appleby, but it was removed from the genus in 2017 due to its similarity to Ichthyosaurus. The genus Protoichthyosaurus was synonymized with Ichthyosaurus by Maisch and Hungerbuhler in 1997, and again by Maisch and Matzke in 2000. However, it was found to be distinct in 2017 by Dean Lomax and colleagues, who separated it from Ichthyosauru

Plutoniosaurus is an extinct genus of ophthalmosaurid ichthyosaur of uncertain validity from the Early Cretaceous (late Hauterivian) of the vicinity of Ulyanovsk, European Russia.

Parahupehsuchus is an extinct genus of hupehsuchian marine reptiles from the Early Triassic of China. The genus is monotypic, known from the single species Parahupehsuchus longus and based on a single specimen. Like other hupehsuchians, it had an elongated torso, a tail nearly as long as the rest of the body, short and paddle-like limbs, extra bones in the fore- and hind limbs, thick ribs and gastralia, neural spines of the vertebrae split into two parts, and bony plates over the neural spines. It differs from other hupehsuchians in having an even more elongated body and wider ribs that touch

Callawayia is an extinct genus of ichthyosaur. It contains the species Callawayia neoscapularis.

Wimanius is a genus of ichthyosaur from the Middle Triassic of Switzerland, containing a single species, Wimanius odontopalatus. It was described by Michael Maisch and Andreas Matzke in 1998 based on an incomplete skull from Monte San Giorgio, a mountain on the Swiss-Italian border. Wimanius possesses teeth on its palate, though whether they were located on the palatine or pterygoid is disputed. Other features of Wimanius include a large orbit and jugals with two rami of similar lengths. Different phylogenetic placements of Wimanius have been recovered by different studies, including it being

Thalassodraco (meaning "sea dragon") is an extinct genus of ophthalmosaurid ichthyosaur from the Late Jurassic (Tithonian) Kimmeridge Clay Formation of England. The type species, T. etchesi, was named in 2020, with the epithet in honour of the discoverer of the holotype, Steve Etches.

Gulosaurus is an extinct genus of basal grippidian ichthyopterygian known from the Early Triassic Vega-Phroso Siltstone Member of the Sulphur Mountain Formation of east-central British Columbia, Canada. Gulosaurus was first named by Robin S. Cuthbertson, Anthony P. Russell and Jason S. Anderson in 2013 and the type species is Gulosaurus helmi. The name means 'Helm's wolverine lizard' and refers to the Wolverine Nordic and Mountain Society, who maintain the area around Wapiti Lake where it was found, and to Dr Charles Helm, who is a leading paleontologist around this same area.

Baisesaurus (meaning "Baise lizard") is an extinct genus of ichthyosauromorph reptiles from the early Triassic (Spathian age) Luolou Formation of Guangxi, China. The genus contains a single species, Baisesaurus robustus, known from a partial postcranial skeleton.

Keilhauia is a genus of ophthalmosaurid ichthyosaur, a type of dolphin-like, large-eyed marine reptile, from the Early Cretaceous shallow marine Slottsmøya Member of the Agardhfjellet Formation in Svalbard, Norway. The genus contains a single species, K. nui, known from a single specimen discovered in 2010 and described by Delsett et al. in 2017. In life, Keilhauia probably measured approximately in length; it can be distinguished by other ophthalmosaurids by the wide top end of its ilium and the relatively short ischiopubis (the fusion of the ischium and the pubis) compared to the femur.

Phantomosaurus is an extinct genus of ichthyosaur that lived during the late Anisian stage of the Middle Triassic. Fossils have been found in southern Germany. It was discovered in 1965 and named in 1997 as a species of Shastasaurus by Sander in the rocks of the Upper Muschelkalk.

Parrassaurus is an ophthalmosaurid ichthyosaur from the late Jurassic La Caja Formation of Mexico named in 2021. Parrassaurus includes one species, Parrassaurus yacahuitztli. The type specimen (CPC 307) was around long.

Argovisaurus (meaning "Aargau lizard") is an extinct genus of ophthalmosaurian ichthyosaurs from the Middle Jurassic (Bajocian) Hauptrogenstein Formation of Switzerland. The genus contains a single species, A. martafernandezi, known from a partial skeleton. Argovisaurus was a large ichthyosaur compared to its relatives.

Eohupehsuchus is a genus of extinct aquatic diapsid from the Upper Spathian (latest Early Triassic) of Hubei Province, located in Central China. The genus is monotypic and belongs to the order Hupehsuchia, whose members are characterized by toothless beak-like snouts, a row of dermal plates along their backs, and aquatic adaptations including paddle-shaped limbs and fusiform bodies with pachyostotic ribs.

Macropterygius is a genus of ichthyosaurs known from the Late Jurassic (Kimmeridgian age) of England (Kimmeridge Clay formation). Though many specimens have been referred to this genus from all over Europe, the type specimen of the only recognized species, M. trigonus, consists of just a single vertebra. Because this cannot be used to distinguish ichthyosaurs from one another, the genus and species are currently considered nomina dubia (doubtful names).

Nannopterygius (meaning "small wing/flipper" in Greek) is an extinct genus of ophthalmosaurid ichthyosaur that lived during the Middle Jurassic to the Early Cretaceous (Callovian to Berriasian stages). Fossils are known from England, Kazakhstan, Russia, and Norway and six species are currently assigned to the genus.

Isfjordosaurus is an extinct genus of ichthyopterygian marine reptile that lived during the Early Triassic. Fossils have been found on the island of Spitsbergen, part of the Svalbard archipelago off the northern coast of Norway. It was formally described by Ryosuke Motani in 1999 and contains the species Isfjordosaurus minor.

Myobradypterygius is an extinct genus of ophthalmosaurid ichthyosaur from the Early Cretaceous (Barremian-Hauterivian) of Argentina and possibly also Chile. One species is known, M. hauthali, which was once believed to have been a species of Platypterygius. Myobradypterygius is thought to have been a small ichthyosaur, with an estimated total body length of .
