Svalbardosaurus

Svalbardosaurus is a genus of ichthyosaurs from the Lower Triassic.
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".
