Gigantoraptor size (holotype) compared to a 1.8-metre-tall (5.9 ft) ... indicating that the unknown skull was over half a metre long and also toothless, ...
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.
Size comparison of megaraptorids. Megaraptorans were medium to large-sized theropods, ranging from Fukuiraptor, which was about 4.2 meters (13.8 feet) in length, to the 9 meter (30 feet) long Aerosteon, the 9 to 10 meter (30 to 33 feet) long Maip [5] and the 12.8 meter (42 foot) long Bahariasaurus, if it is a member.

Its skull was long, low, and slender. Similar to tyrannosaurs, it had small, conical teeth at the front of its jaws, and longer, more curved teeth near the back. The hand claws of Megaraptor were very long and strongly curved, with the claw of the first finger measuring 35 cm (14 in). The claw of the third finger was the smallest, only 6.5 cm ...
Some taxa (such as Citipati, Corythoraptor, Rinchenia) had a midline crest on top of the skull, resembling that of a cassowary. Other distinguishing characteristics include a bony spike intruding on the mandibular fenestra , nostrils placed very high and far back on the snout, an extremely thin bony bar beneath the eye, and highly pneumatized ...
Researchers unearthed the skull of a previously unknown starling-sized bird species named Navaornis hestiae that was so well preserved they were able to digitally reconstruct its brain and inner ...
The tiny jaws of Caenagnathasia suggest a small animal, perhaps the size of a turkey. Anzu wyliei , from the Hell Creek Formation is a much larger animal, considerably larger than a human. 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 ...
