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.
Utahraptor was one of, if not the largest and heaviest of all dromaeosaurids, with the largest assigned specimen BYUVP 15465 having a femoral length of 56.5–60 cm (22.2–23.6 in). [8] [9] Utahraptor is estimated to have reached 5,5 meters in length and somewhat less than 500 kg (1,100 lb), comparable in weight to a polar bear.
This is the latest accepted revision, reviewed on 20 September 2024. Megaraptora is a clade of carnivorous theropod dinosaurs with controversial relationships to other tetanuran theropods. Its derived members, the Megaraptoridae are noted for their large hand claws and powerfully-built forelimbs, which are usually reduced in size in other large ...
Not only that, but megaraptors reportedly had 12-inch long claws and razor-sharp teeth that were 3.5 inches long. While terrifying, we have comfort knowing we will never meet this carnivore face ...
Maip. 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.
Siats (/see-ats/) is an extinct genus of large theropod dinosaur known from the Late Cretaceous Cedar Mountain Formation of Utah, United States. It contains a single species, Siats meekerorum. [1][2] It was initially classified as a megaraptoran, a clade of large theropods with very controversial relationships.
Binomial name. †Australovenator wintonensis. Hocknull et al. 2009. Australovenator (meaning "southern hunter") is a genus of megaraptoran theropod dinosaur from Cenomanian (Late Cretaceous)-age Winton Formation (dated to 95 million years ago [1]) of Australia. Some specimens from the Albian -aged Eumeralla Formation may belong to Australovenator.
