> How widespread are fused nasals outside tyrannosauroids and oviraptorids? (Though this character would certainly add noise only.)

Oviraptorids don't have fused nasals,

Sure?

(I'm too much limited to reconstructions in lateral view.)

but abelisaurids and spinosaurids do.

So it's an uninformative autapomorphy within Coelurosauria. :-(

What about epipophyses on the cervicals, normally present, absent in Calamosaurus, ornithomimosaurs and troodontids and apparently not described for compsognathids? (Dirty little problem -- I don't even know what an epipophysis is. :-] )

Is it ACCTRAN, DELTRAN or nothing? Does changing this setting change the outcome?

That only changes the characters diagnosing various clades, not the topology. It was DELTRAN though.

But these diagnosing characters are used to find the clades, no? So I'd expect changes in the topology?

`-+-Troodontidae
`-+-Microraptor
`-Rahonavis

Wow, strange. Didn't you get such an assemblage once too?

I've never found [...]. Microraptor and Rahonavis sometimes form a clade, with or without Archaeopteryx.

Didn't you have that clade next to Troodontidae when you left out the flight-related characters? Or was that somebody else?

Does something happen when Bagaraatan is deleted?

It makes tyrannosauroids clade with the bullatosaurs, but that's it.

Hey! That gives good old Arctometatarsalia back (save the strange addition of Microraptor + Rahonavis)! More than I dared to hope for! ;-)
