Svalbardosaurus is a genus from the Lower Triassic, initially identified as an ichthyosaur but later reinterpreted as an amphibian.
The type species is Svalbardosaurus crassidens, named and described by Jean-Michel Mazin in 1981.Mazin, J.M., 1981, "Svalbardosaurus crassidens n. g. n. sp., un Ichthyopterygien nouveau du Spathien (Trias inférieur) du Spitsberg", Compte rendu hebdomadaire des seances de l’Académie des Sciences de Paris, (II) 293: 203-205 The generic name refers to the Svalbard archipelago, of which Spitsbergen is a part, where the remains have been found. The specific name means "thick tooth" in Latin. The genus is solely based on some conical teeth and often considered a nomen dubium.
