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.

Gigantoraptor looks really good, I like how you've added a bit of a crest and scaled down the eye (the "official" reconstruction just looks like a gargantuan Ingenia). One thing I'd do is feather the hands--the position of Citipati nesting specimens indicates they had proper wings stemming from digit 2, and Caudipteryx also has primary feathers.
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 ...
Herrerasaurus is likely a genus of saurischian dinosaur from the Late Triassic period. Measuring 6 m (20 ft) long and weighing around 350 kg (770 lb), this genus was one of the earliest dinosaurs from the fossil record.
