       Gunakadeit is a genus of thalattosaur that lived in waters around what is now North America during the late Triassic.‭ ‬Gunakadeit is a thalattosaur genus of contrasts.‭ ‬In one respect Gunakadeit appear to have been quite primitive in form when compared to other thalattosaurs.‭ ‬In another,‭ ‬Gunakadeit lived towards the end of the Triassic,‭ ‬after many of the more advanced form thallatosaurs had gone extinct.‭ ‬Gunakadeit seems to have been an exclusively aquatic reptile with jaws that end in a sharp toothless point.‭ ‬Gunakadeit would be expected to have been a predator of fish and soft bodied marine creatures such as cephalopods.
