The dinosaur of the day: Khaan
- Oviraptorid that lived within the Late Cretaceous in what’s now Mongolia (Djadochta Formation)
- Seemed lots like different oviraptorids
- Didn’t have a crest on its head, like Oviraptor
- Had a beak, no tooth
- Had a brief tail
- Had a small physique
- Three specimens discovered
- Two people have been about 4 ft (1.2 m) lengthy, third particular person discovered that was bigger (discovered one examine that talked about 6.5 ft or 2 m lengthy)
- Might have been an omnivore
- Most likely had feathers
- Had massive toes. Articulated toes in all three specimens have been nicely preserved, and the entire foot is about 32% of the size of the hindlimb
- Sort species: Khaan mckennai
- First discovered with its tail protruding a small hill, and the second specimen was discovered close to it. Each had damaged necks, killed by the identical occasion
- At first, regarded as Ingenia, in 1995 and 1996
- However 2001 examine discovered sufficient variations within the palms to be its personal genus
- Named in 2001 by James Clark and others
- Genus title comes from the Mongolian phrase khaan, which means “lord” or “ruler”
- Species title is in honor of paleontologist Malcolm Carnegie McKenna
- Intently associated to Conchoraptor
- Holotype is a virtually full skeleton

- The one with muscle mass for tail feather shows was in all probability male, and the one with the smaller boney constructions was in all probability feminine (would have had extra room/been simpler to put eggs)
- The group famous that this occasion of sexual dimorphism was linked solely to Khaan mckennai, and there weren’t sufficient specimens of different oviraptorosaurs to know for certain
