Mystriosuchus (meaning "spoon-crocodile")[1] is an extinct genus of phytosaur that lived in the Late Triassic (middle Norian) in Europe and Greenland.

[4] Cranial morphology is suggestive of a primarily fish eating diet, having long jaws like those of the modern gharials.

M. westphali, on the other hand, has multiple bony crests along the upper jaw, most prominently at the base and tip of the snout.

Because of incomplete preservation, it can't be distinguished where the neck meets the torso, although at least 17 of the 25 vertebrae come from the latter.

At the end of the tail the vertebrae become more slanted, and the chevrons form an inverted 'T' shape, which is not seen in other phytosaurs but in sauropterygians or some crocodilians.
