Teeth have been found in many genera. Collectively, megaraptorans can be reconstructed as having a long, lightly built skull with many relatively small teeth. [9] Based on Megaraptor, the premaxillary bone at the tip of the snout is small, with a long and rod-like branch of bone which extends above the external nares (nostril holes).
Megaraptor was initially described as a giant 8 metres (26 ft) long coelurosaur, known primarily from a single claw (about 30 cm long) that resembled the sickle-shaped foot claw of dromaeosaurids. [2] The discovery of a complete front limb, however, showed that this giant claw actually came from the first finger of the hand.
Maip is a genus of large megaraptorid theropod dinosaur from the Late Cretaceous (Maastrichtian) Chorrillo Formation of Santa Cruz, Argentina. The genus contains a single species, M. macrothorax, known from an incomplete, disarticulated skeleton. Maip may represent the largest megaraptorid known from South America, and possibly the world.
Murusraptor. Murusraptor ("wall thief") is a genus of carnivorous megaraptoran theropod dinosaur from the Sierra Barrosa Formation, part of the Neuquén Group of Patagonia, in Argentina, South America. It is known from a single specimen that consists of a partial skull, ribs, partial pelvis, leg and other assorted skeletal elements.
Orkoraptor is a genus of medium-sized megaraptoran theropod dinosaur from the late Cretaceous Period of Argentina. It is known from incomplete fossil remains including parts of the skull, teeth, tail vertebrae, and a partial tibia. The specialized teeth resemble those of some maniraptoriform theropods, namely the deinonychosaurs and compsognathids.
The gracile morphology of the skull also concludes that this genus had a specialisation towards prey capture using its arms and hands. [21] A 2016 study used CT scans of an emu foot to digitally reconstruct the musculature and soft tissue of an Australovenator foot, as well as determine how soft tissue affects flexibility. The study determined ...
Type species. †Fukuiraptor kitadaniensis. Azuma & Currie, 2000. Fukuiraptor ("thief of Fukui ") was a medium-sized megaraptoran theropod dinosaur of the Early Cretaceous epoch (either Barremian or Aptian) that lived in what is now Japan. [1] Fukuiraptor is known from the Kitadani Formation [2] and possibly also the Sebayashi Formation.
Cryolophosaurus. Cryolophosaurus (/ ˌkraɪəˌloʊfəˈsɔːrəs / or / kraɪˌɒləfəˈsɔːrəs /; KRY-ə-LOH-fə-SAWR-əs) is a genus of large theropod dinosaur known from only a single species Cryolophosaurus ellioti, from the early Jurassic of Antarctica. It was one of the largest theropods of the Early Jurassic, with the subadult being ...
