In Depth

       Described in‭ ‬2015,‭ ‬Carnufex may well have been one of the key predators that lived in what would become the eastern USA during the Triassic about‭ ‬231‭ ‬million years ago.‭ ‬Carnufex was a crocodylomorph,‭ ‬a distant relative to today’s crocodiles,‭ ‬and one that seems to have been a bipedal predator of moderately sized animals.‭ ‬The authors of the‭ ‬2015‭ ‬description have noted several features of the known bones of Carnufex making it stand out from related genera as a distinct genus.‭ ‬They also noted that the skull of Carnufex seems to be quite transitional linking differences between different groups of crocodylomorphs.‭ ‬As a fairly fast bipedal predator,‭ ‬Carnufex may have filled an ecological gap that had not yet been filled by the emerging theropod dinosaurs,‭ ‬though ultimately by the Jurassic,‭ ‬the theropod dinosaurs would have replaced crocodylomorphs like Carnufex as top predators.

       The name Carnufex is derived from the Latin word for‭ ‘‬butcher‭’‬,‭ ‬while the type species name‭ ‘‬carolinensis‭’ ‬simply means from Carolina.‭ ‬Recombined into English grammatical order,‭ ‬and Carnufex carolinensis translates as‭ ‘‬Carolina’s butcher‭’‬.
