I'm guessing this is using Gauthier's definition of Maniraptora (= all taxa 
closer to Neornithes than to _Ornithomimus_), and followed by Holtz (1996), 
rather than Sereno's newer definition (= all descendants of the most recent 
common ancestor of _Oviraptor_ and Neornithes).

I don't want to sound cheeky, but does this analysis take into account the 
exclusion of the referred manus (AMNH 587) from _Ornitholestes_?
