Ah, but no. Since he was too ignorant to correctly root his tree, we must do 
it for him:

Nothing of this changes.

Oho!

What modifications did they suggest to *Rahonavis*?

Strange clade. Strikes me as... backwards... of course it's not a segnosaur 
analysis, but maybe it indicates that the segnosaurs belong somewhere else 
in the tree?

So Dromaeosauridae is restored, and *Buitreraptor* and even *Rahonavis* stay 
inside...

Extremely well-behaved...

Badly behaved!

That's normal.

That's normal for your analysis (I never got that, I think).

This is quite a performance! :-o

:-o
I guess its toothless pmx is among the reasons for this? I have this 
character in my matrix, but nevertheless *B.* stays in Enantiornithes 
(usually next to *Gobipteryx* for readily apparent reasons).

These last two used to be the basalmost euorniths, and now they're among the 
most derived ones... :-o
