Fig. 5. Amblyrhiza inundata AMNHVP 11842, left auditory region; stereopair view (with key, opposite page) in oblique lateral aspect. Asterisk, raised seam of ectotympano-ectotympanic suture continued onto floor of external acoustic meatus. Position of the posttympanic foramen is hidden by the projecting external acoustic canal. Paroccipital process is heavily pneumatized, in contrast to conditions in Eumegamys (see text).
