Named By: Rodolfo Anibal Coria & Philip John Currie - 2016.
Classification: Chordata, Reptilia, Dinosauria, Saurischia, Theropoda, Megaraptora.
Species: M. barrosaensis (type).
Size: Holotype individual estimated to be about 6.4 meters in length. However this is of an immature individual, fully grown adults would have been larger.
Known locations: Argentina, Patagonia - Sierra Barrosa Formation.
Time period: Coniacian of the Cretaceous.
Fossil representation: Partial skull and post cranial skeleton.
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
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.
