The 5th cerebral nerve once more

["David Marjanovic" <david.marjanovic@gmx.at>]

On 24 November I wrote the following and have not got any answer. I need
one, so I'd like to pose the question again. Thanks in advance! :-)
(Or is a paper in the works on it?)

---------------------------------------------------
Yoichi Azuma & Philip J. Currie: A new carnosaur (Dinosauria: Theropoda)
from the Lower Cretaceous of Japan, Canadian Journal of Earth Sciences 37,
1735 -- 1753 (?December 2000)

This paper (the description of *Fukuiraptor*) includes a long character
list, long character matrix and small cladogram. "Except where stated
otherwise, characters are derived from Holtz (1994)" which I haven't read
that closely. Character 16 is

"Braincase, trigeminal nerve, separation of ophthalmic branch within the
bone; 0, no; 1, incipient with trough in lateral surface of laterosphenoid;
2, complete with ophthalmic branch enclosed in a tube within
laterosphenoid."

As expected, *Acrocanthosaurus* and *Herrerasaurus* (the outgroup) are coded
0, *Fukuiraptor* and *Sinosauropteryx* are coded ?, Dromaeosauridae 1,
Ornithomimidae and Tyrannosauridae 2. More surprising but already discussed
onlist is 2 for *Allosaurus*, which might be a real convergence, given that
*Sinraptor* is coded 1. What is really surprising is the 1 rather than 2 for
Oviraptoridae. It contradicts everything I've read so far. Can it simply be
a typo, or is it real? Any clarification is appreciated. (In the cladogram
this character never reverses, Dromaeosauridae and Oviraptoridae come out as
sister groups, birds, Troodontidae, and "enigmosaurs" except Oviraptoridae
are not included in the cladogram, but coelurosaur relationships are not the
topic of the paper.)
