| Description |
Entombed in fossilized skulls of Rhamphorhynchus muensteri (upper, background) and Anhanguera santanae (lower, foreground) are the remains of semi-circular canals (shown in green), the inner-ear structures that assist in equilibrium maintenance by providing leveling information to the brain. When their respective canals are oriented to be level along a horizontal plane, the skull of Rhamphorhynchus is horizontal, while the skull of Anhanguera tilts downward. This positioning offers clues to feeding, flying and other behaviors of these dinosaurs. |
