Gigantoraptor is the largest known oviraptorosaur for which skeletal material is available. Approximately three times as long and 35 times heavier than the largest earlier-discovered oviraptorosaur Citipati , the holotype of Gigantoraptor has been estimated at 8 m (26 ft) long with a height of 3.5 m (11 ft) at the hips, and a ponderous weight ...
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 6–7 metres (20–23 ft) in length and somewhat less than 500 kg (1,100 lb), comparable in weight to a polar bear.
Megaraptor (lit. ' large thief ') is a genus of large theropod dinosaur that lived during the Turonian and Coniacian ages of the Late Cretaceous.Its fossils have been discovered in the Patagonian Portezuelo Formation of Argentina, South America.
They are distinct for their characteristically short, beaked, parrot-like skulls, with or without bony crests atop the head. They ranged in size from Caudipteryx, which was the size of a turkey, to the 8-meter-long, 1.4-ton Gigantoraptor. [2] The group (along with all maniraptoran dinosaurs) is close to the ancestry of birds.

Oviraptor (/ ˈ oʊ v ɪ r æ p t ər /; lit. ' egg thief ') is a genus of oviraptorid dinosaur that lived in Asia during the Late Cretaceous period. The first remains were collected from the Djadokhta Formation of Mongolia in 1923 during a paleontological expedition led by Roy Chapman Andrews, and in the following year the genus and type species Oviraptor philoceratops were named by Henry ...

If Gigantoraptor erlianensis is a caenagnathid, then it would represent far and away the largest member of the group, measuring up to 8 meters (26 ft) in length and weighing up to 2 metric tons (2.2 short tons). [23]
