In Depth

       The holotype remains of Murusraptor were first recovered across‭ ‬2001‭ ‬and‭ ‬2002,‭ ‬but were not described in a scientific paper until‭ ‬2016.‭ ‬Murusraptor is identified as a megaraptoran theropod dinosaur,‭ ‬and one of potentially large size.‭ ‬The holotype individual of Murusraptor has been estimated to have been just short of six and a half meters in length at the time of its death.‭ ‬However,‭ ‬sutures in the known portions of the skull indicate that this individual was still immature and hence not fully grown.‭ ‬This would mean that fully grown adults would have been substantially larger,‭ ‬though how much so is still unknown.

       So far only the rear half of the skull of Murusraptor has been recovered.‭ ‬A key feature of this skull however is that even at the rear it was very narrow.‭ ‬This is a strong indicator that the snout of Murusraptor would have also been narrow,‭ ‬a feature that it would have shared with some other megaraptoran theropod dinosaurs,‭ ‬including the Megaraptor genus.
