The Skull of Nigersaurus, an Unusual Sauropod  Dinosaur from the Cretaceous of Africa

 

Movies
QuickTime format. Download the free player here. Download labeled images at the bottom of the page.

Animation of the skull, brain endocast, and inner ear of the diplodocoid sauropod dinosaur Nigersaurus. The animation starts with sortuva "normal-looking" head posture, but transparency reveals a rotated brain and inner ear; rotating the inner ear so that it's oriented like modern-day animals do when they're alert shows that Nigersaurus had an almost vertical alert posture. This movie was generated to accompany the "Bizarre Dinosaurs" premiere on 11 Oct 2009 on the National Geographic Channel. Also available on YouTube and Facebook.
