Re: Coelurosaur phylogeny

I wasn' t aware that Enigmosauria had been published. Can you post the citation? I was aware it had not yet been defined.

Out of curiousity, do you code Dromaeosauridae, Ornithomimosauria, Alvarezsauridae, Segnosauria, and the Troodontidae as OTUs or do you have them split up as multiple OTUs and you've just chosen not to reveal the internal phylogeny of those clades onlist?

I just noticed now that the Arctometatarsalia is the sistergroup to Enigmosauria in your analysis. I feel stupid for not catching it previously. What characters support this relationship or is that something you don't want to share just at the moment, which might be understandable?

I'm not at all surprised by their closeness. These two have a love-hate thing going on when it comes to phylogeny. I never see one very far from another.

What supports the _Rahonavis_ + _Shenzhouraptor_ + _Jeholornis_ clade?

3.  How did you get _Avimimus_ and _Archaeornithoides_ to fall in with the
> arctometatarsalians (which I presume is the ornithomimosaurs)?

By coding them for the characters I included. ;-) 

Well, duh! :-D
