dinosaur eyes

[jwixom@western.edu (Jo Wixom)]

Hello from Colorado.  I am putting together some curriculum material for
teaching optics through dinosaurs.  I can't find any good references about
dinosaur eyes, such as sizes of eyeballs for some of the more common
species, speculation on numbers of rods vs cones, existance of brain cases
with optic nerve, etc.  Anyone doing research or having knowledge that
could help me out here would be much appreciated.  Thanks, Jo Wixom,
