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.

An unusual result was found by Hartman and colleagues in 2019, where both Utahraptor and Achillobator were found to be outside Dromaeosaurinae and Velociraptorinae, joined by Yixianosaurus, [22] which is usually considered an anchiornithid. [16] The left cladogram follows Cau et al. 2017, [16] while the right cladogram follows Jasinski et al ...
Citipati was a large-bodied oviraptorid, with the largest individuals being emu-sized animals; it has been estimated at 2.5–2.9 m (8.2–9.5 ft) in length with a weight between 75–110 kg (165–243 lb), [21] [22] [23] and was one of the largest known oviraptorosaurs until the description of Gigantoraptor. [24]
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]
