One of the largest ichthyosaurs, adults ranged in length from {{convert|6|m|ft|abbr=on}} up to {{convert|10|m|ft|abbr=on}} long. It was one of the least fish-like of the ichthyosaurs, lacking a dorsal fin and fluked tail. Consequently, Cymbospondylus probably swam by wriggling its body from side to side like a modern sea snake. |

Lived during the Sinemurian stage in what is now England. It is characterized by the extreme elongation of the rostrum, giving the animal a swordfish-like look. Excalibosaurus is known from two skeletons. The holotype was from a juvenile with an estimated body length of 4 m. The estimated body length of the second specimen, discovered in 1996, is 7 m. |

An extinct genus of marine reptile from Spitsbergen. It has been considered an ichthyopterygian, however a study by Motani in 2000 showed that it lacks the basal synapomorphies of Ichthyopterygia. As such, its exact position in the diapsid tree is currently unknown. |

One of the largest ichthyosaur genera that has yet been found. Fossils of Shonisaurus were first found in Nevada in 1920. It lived during the Norian stage of the late Triassic period and had a long pointed mouth that contained teeth only at the front end. S. popularis specimens reached a length of {{convert|15|m|ft|abbr=off|sp=us}}. A second species, S. sikanniensis, was later discovered in British Columbia and has an estimated length of {{convert|21|m|ft|abbr=off|sp=us}}. |
