NSF PR 03-124 - October 29, 2003

Video - Not All Aerial Reptiles Were Level-Headed, CT Scans Show
Inside view of pterosaurs’ brain yields insights to posture, behavior

This animation demonstrates the relationship of head orientation to the inclination of the lateral semicircular canals (shown in blue) of the larger of the two pterosaurs studied, Anhanguera santanae. When the semicircular canals are brought to a normal near-horizontal position, the long axis of the head turns downward.
