Khaan is a dinosaur that was initially mistaken, as many have been in the past, and was originally assigned to an occupied genus (Ingenia). In many ways Khaan is like every other oviraptorid dinosaur, and in enough ways, it is not. The remains are well enough preserved that the differences between Khaan and other oviraptorids were able to be seen by the describing authors and subsequent researchers as well. The manus is the main source of difference in Khaan as it lacks a character found in other members of the family. The difference is small, and probably cannot be easily seen in photographs of the holotype, but it does exist, and that is enough.
