In Depth

       Because the skull of Westphaliasaurus is so far unknown it is impossible to say for certain what the diet of Westphaliasaurus was.‭ ‬However most of the early Jurassic plesiosaurs were dedicated hunters of fish and possibly also squid,‭ ‬prey animals that would become a staple part of the diets of plesiosaurs throughout the Mesozoic.‭ ‬Unless future discoveries prove otherwise,‭ ‬it‭’‬s reasonable to assume that Westphaliasaurus also had a similar diet.

       The species name W.‭ ‬simonsensii is in honour of S�nke Simonsen,‭ ‬the palaeontologist who discovered the remains.
