Re: Segnosaurs ejected from AVES
To tell you truth Jaime, one reason I don't like the name Maniraptora
for the whole group is that most birds don't go around "manuraptoring" their
food. And it is not apomorphy-based, so not exactly equivalent in any case.
Anyway, don't get too upset too fast, because this is an example of the
"real world" of eclecticism in action. You might even end up finding that a
little eclecticism is advantageous in the end. It might be a little
uncomfortable, but often "no pain means no gain". Give it a chance.
I would be interested to know how Beipiaosaurus would be coded with
your six semilunate characteristics. It's possible that segnosaurs (sans
Beipiaosaurus) split off first, and that Beipiaosaurus then split off
between them and the rest of the "true" semilunate forms. In other words,
Segnosauriformes sensu lato could be paraphyletic, and perhaps Beipaiosaurus
represents the transition to the "true semilunate".
I would also be interested to know if Beipiaosaurus had a convex
coracoid glenoid, as that transition seems to be occurring around the same
time. So don't get too upset, because I think eclecticists and cladists can
learn from each other when they cooperate. I just don't think "strictly
cladistic" science is the only best way to discover true phylogenies. This
is a great experiment, and we might all learn something.
