I thought Czerkas & Czerkas (big book, 1990?) had based their family
tree of dinosaurs on something widely accepted... never mind. For some time
(later) megalosaurids were repeatedly regarded as possible ceratosaurs,
though.
Britt (1991) thought the latter might be the
case. Know any other non-popular references?
How widespread are fused nasals outside
tyrannosauroids and oviraptorids? (Though this character would certainly add
noise only.)
Oviraptorids don't have fused nasals, but
abelisaurids and spinosaurids do.
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.
-+-Ornithomimosauria
`-+-Troodontidae `-+-Microraptor `-Rahonavis Wow, strange. Didn't you get such an assemblage
once too?
I've never found a Bullatosauria exclusive of
Neornithes (though ornithomimosaurs recently grouped with enigmosaurs), nor
have Microraptor or Rahonavis ever claded closer to troodontids than
neornithines. I MAY have had alvarezsaurians clade with troodontids in the
past, but certainly nothing else. Microraptor and Rahonavis sometimes form
a clade, with or without Archaeopteryx.
Does something happen when Bagaraatan is
deleted?
It makes tyrannosauroids clade with the
bullatosaurs, but that's it.
