Gotta collect the data first, and Dr. Stevens' paper is a good start.

Another nagging question (well, at least for moi):  Does significant
overlap of field of vision seen in fossil skulls NECESSARILY imply that
the animal had binocular vision?  Are there extant animals with large FoV
overlap that lack binocular vision?
