CLIFFORD, A.B.*; WITMER, L.M.: The Narial Anatomy of Hooded Seals (Cystophora cristata) with Respect to other Carnivora. Male hooded seals (Phocidae: Cystophora cristata) have two inflatable devices, both of which involve modification of their narial and facial anatomy. 1) An inflatable integumentary bladder is formed as the elastic and hairy epithelium covering the narial region […]

Sedlmayr, J.C.*; Witmer, L.M.: The Avian Suborbital Air Sac and its Potential Role in Brain Cooling in Birds and Other Dinosaurs The avian suborbital air sac, a caudal diverticulum of the antorbital paranasal air sinus, partially encircles the eyeball and interleaves between portions of the jaw musculature.
