       Sclerocormus is a genus of primitive ichthyosauromorph that lived in waters around Asia during the early Triassic.‭ ‬As a member of the group that was ancestral to the ichthyosaurs,‭ ‬Sclerocormus itself did‭ ‬not look that much like one.‭ ‬The body of Sclerocormus was quite stout and stocky,‭ ‬while the tail of the animal took up just over half of the total body length.‭ ‬The belly of Sclerocormuswas not as deeply round as later ichthyosaurs,‭ ‬and this feature‭ ‬combined with the straight relatively thin tail have come together to form a creature that lived in shallow waters.
       Sclerocormus possessed short jaws that could be opened very quickly.‭ ‬It is thought that the sudden vacuum of the jaws opening could suck nearby animals into the mouth.‭ ‬The jaws being toothless mean that Sclerocormus would have been more suited to hunting soft bodied prey such as cephalopods and other molluscs.
