Identification of Nasal Septa

["Waylon Rowley" <hot__male60@hotmail.com>]

I'm trying to compile a complete description of the bones of a theropod 
dinosaur. It's a massive task as you can imagine, and i'm always running 
into gaps in my knowledge about their morphology. One particular thorn in my 
side is the name of the septum rostral to the orbit and beneath the median 
internasal suture that divides the nasal passages. I've also been wondering 
about the medial shelves that seem to project either from the maxillae or 
ventromedial margins of the nasals and floor the nasal passage proper. Any 
information on these structures (including vascularization, innervation, 
size) would be greatly appreciately and make my life a whole lot easier.
