Svalbardosaurus
Svalbardosaurus is a genus from the Lower Triassic, initially identified as an ichthyosaur but later reinterpretted as an amphibian. The type species is Svalbardosaurus crassidens, named and described by Jean-Michel Mazin in 1981. 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. See also
