[9] [10] Similarly, quill knobs (anchor points for wing feathers on the ulna) have been reported in the oviraptorosaur species Avimimus portentosus. [11] Additionally, a number of oviraptorid specimens have famously been discovered in a nesting position similar to that of modern birds.
Citipati embryo IGM 100/971. In 1993, a small fossilized oviraptorid embryo, labelled as specimen IGM 100/971, was discovered in a nest at the Ukhaa Tolgod locality of the highly fossiliferous Djadokhta Formation, Gobi Desert, during the Mongolian Academy of Sciences-American Museum of Natural History paleontological project.
Skull of Tongtianlong limosus. Tongtianlong was a sheep-sized member of the oviraptorids, a group of omnivorous, feathered, bird-like theropods. [2] The describers of Tongtianlong recognized that it possessed a set of distinctive characteristics that differentiated it both from other oviraptorosaurs.
