In Depth

       Limnoscelis is a genus of diadectomorph that lived in North America during the early Permian period.‭ ‬Diadectomorphs‭ (‬there name taken from the genus Diadectes‭) ‬are often identified as being herbivorous,‭ ‬though Limnoscelis seems to be an exception to this with the dentition and body form of a primitive predator.‭ ‬Limnoscelis however was not a pursuit predator as the ankle bones of the feet were fused.‭ ‬This meant that the movement range of the legs was limited,‭ ‬restricting fast and agile movement,‭ ‬but it also means they were also very strong,‭ ‬meaning that Limnoscelis would have been better at holding on to larger slow moving prey.
