Nannopterygius (meaning ″small wing/flipper″ in Greek) is a genus of ophthalmosaurid ichthyosaur that lived in the Middle to Late Jurassic (Callovian to Tithonian stages).[1] Fossils have been found in England and Germany.[2] The first specimen was found in the Kimmeridgian Kimmeridge Clay Formation of Kimmeridge Bay, Dorset, UK and described by Hulke in 1871, who named it Ichthyosaurus enthekiodon.[3] A year earlier, Hulke had described some remains from the same horizon and locality that he thought were ichthyosaurian, naming them Enthekiodon (no species given).[4] These are now lost, but Hulke considered them sufficiently similar to demote the name to species level.[3] In 1922, Huene separated this species into the new genus Nannopterygius, named for the small fore- and hindpaddles.[5]
