Torvoneustes

When the skull of Torvoneustes was originally described it was thought to belong to a species of Metriorhynchus,‭ ‬M.‭ ‬superciliosus.‭ ‬However the later discovery of post cranial remains led to the conclusion that the skull remains did not belong to that species of Metriorhynchus,‭ ‬and they were re-described as a new species of Dakosaurus,‭ ‬D.‭ ‬carpenteri,‭ ‬in‭ ‬2008.‭ ‬Later in‭ ‬2008,‭ ‬the remains‭ ‬were again moved to a‭ ‬another genus as a species of Geosaurus,‭ ‬G.‭ ‬carpenteri.‭ ‬Ultimately in‭ ‬2010,‭ ‬the remains were again reclassified,‭ ‬this time as their own genus,‭ ‬Torvoneustes.‭ ‬In‭ ‬2013‭ ‬a second species,‭ ‬T.‭ ‬coryphaeus,‭ ‬was named from further remains recovered from the Kimmeridge Clay Formation. Torvoneustes was a metriorhynchid thalattosuchian,‭ ‬a creature that can be more simply referred to as a marine crocodile adapted for life in the sea.‭ ‬The legs were flattened and shaped more like paddles,‭ ‬while the tail would have ended with a fish-like fluke,‭ ‬similar to those of ichthyosaurs.‭ ‬The hard osteoderms that are commonly found in the skin of terrestrial‭ (‬land dwelling‭) ‬crocodiles were also gone so that the skin had a more hydrodynamic surface,‭ ‬making swimming easier and more efficient. Despite being large Torvoneustes seems to have been adapted more for‭ ‬a piscivorous‭ (‬fish eating‭) ‬diet.‭ ‬This is because the jaws of Torvoneustes are relatively long with teeth that are smaller than those of suspected hyper carnivorous genera like Dakosaurus which were better at slicing the flesh of other marine reptiles.‭ ‬This is not to say that Torvoneustes would not target other marine reptiles in its pursuit of prey,‭ ‬just that the teeth and jaws would be better suited for work upon fish. As far as comparisons to other metriorhynchid crocodiles go,‭ ‬Torvoneustes was larger than Geosaurus and Metriorhynchus,‭ ‬but roughly comparable to larger Dakosaurus.‭ ‬Even larger than all of these though was Plesiosuchus.
