In Depth

       The genus Inostrancevia is one of if not the largest gorgonopsid to every walk the Earth.‭ ‬At up to three and a half meters long there is little doubt that Inostrancevia would have been the apex predator of its environment,‭ ‬hunting other large vertebrates which may have included large and armoured pareiasaurs such as‭ ‬Scutosaurus.‭ ‬As would be the expected the skull is large and robustly constructed with upper canine teeth that grew up to fifteen centimetres long.‭ ‬It is the combination of the teeth and skull mounted on a powerful body that may have been the key to defeating the armour of such prey.
