Sure my knowledge is lagging behind -- I was relying on "Dinosaurs: The
Encyclopedia" which mentions the yet-unnamed *Nedcolbertia* after

This is quite basal indeed. Convinced me :-) But tyrannosaurs don't have an

I see. So anyone can come and suggest another topology without suffocating
under mountains of evidence? :->

How did these come out as synapomorphies? I mean, lots of others have one or
both... *Ornitholestes*? Maniraptoriformes? ~:-|
How do you define the semilunate? Does *Allosaurus* have it, or does it have
to be bigger, like in e. g. *Ornitholestes* and dromaeosaurs?

Why "finally"? Didn't it before? Is it _so_ basal, or just too fragmentary?
