Animation of the flow of air through the head of Tyrannosaurus rex. The main airway is shown by the large red arrow. The wavy arrow depicts the more slowly moving air in the olfactory region, where the sensory tissue is located, just in front of the olfactory bulb of the brain. The opening painting was done by Bill Parsons under Witmer's direction for a 2001 Science paper: http://www.oucom.ohiou.edu/dbms-witmer/Downloads/2001_Witmer_nostrils.pdf For details of the airflow, see Witmer & Ridgely's 2009 paper: http://www.oucom.ohiou.edu/dbms-witmer/Downloads/2009_Witmer_&_Ridgely_tyrannosaur_brains_&_ears.pdf Animation rendered in Amira and QuickTime by Ryan Ridgely.
