I can dig out the references but, to the best of my casual knowledge, the
sinus system in the back of croc skulls is completely enclosed and
air-filled. The function of this system is unknown. Check out Iordansky
(1973) in the Biology of Reptiles series. I can't recall any more recent
work that adds anything new to what he had to say about this.
