The largest Citipati were emu-sized animals and, at about 3 meters (10 ft) long, were the largest known oviraptorids until Gigantoraptor was described in 2007.
Like other oviraptorids, Citipati had an unusually long neck and shortened tail, compared to most other theropods.
Its skull was unusually short and highly pneumatized (riddled with openings in the bone structure), ending in a stout, toothless beak.
Perhaps the most distinctive feature of Citipati was its tall crest, superficially similar to that of a modern cassowary.
