Fig. 6. Basicrania of Prionodon (AMNH 163595, A) and Poiana (AMNH 51438, B) in ventral view. The bony floor of the posterior chamber of the auditory bulla has been removed on one side in each individual to show the ectotympanic resting on the petrosal promontorium, and the size of the posterior chamber formed by the caudal entotympanic. Note the more expanded or inflated posterior chamber in Poiana relative to Prionodon.
