Pixar is due to release a new dinosaur movie in a couple years! Official synopsis:
What if the cataclysmic asteroid that forever changed life on Earth actually missed the planet completely and giant dinosaurs never became extinct? This hilarious, heartfelt and original tale is directed by Bob Peterson (co-director/writer, “Up;” writer, “Finding Nemo”) and produced by John Walker (“The Incredibles,” “The Iron Giant”).
