SOCIETY OF VERTEBRATE PALEONTOLOGY, MEMOIR 3<br />
FIGURE 6. Archosaurian heads with the facial s<strong>of</strong>t tissues that are <strong>of</strong> particular interest here. All are shown in obliaue rostrodorsolateral views.<br />
A, Alligator mississippiensis. B, Anser anser. C, Allosaurus fragilis. sokt tissues shown include the eyeball, maxi11&~ nerve, main paranasal air<br />
sinus (i.e., antorbital sinus [= caviconchal sinus <strong>of</strong> crocodilians]), nasal gland, nasolacrimal duct, and the dorsal pterygoideus muscle. Some bones<br />
are partially transparent. The position <strong>of</strong> the nasal gland in Allosaurus fragilis is defensible (see text) but is more speculative (a level II or III<br />
inference).
