In addition to Docter's project, the Untitled Pixar Movie about Dinosaurs will be directed by Pixar veteran Bob Peterson and produced by John Walker.
The movie is aiming for a holiday 2013 release. The story is set in a world where an asteroid didn't hit the Earth, thus allowing the creatures to keep living and evolving.
An image of concept art shown to the hall was of a small humanoid silhouette on top of the head of a brachiosaurus.
Peterson said he was inspired by a World's Fair he attended as a child where he saw animatronic dinos created by Disney.
