Stunning fossil finds have revealed the fascinating stories of major transitions in the history of life on our planet—from fish that gained the land, to reptiles that took to the air, and primates that walked on two legs.

The Great Transitions film trilogy features leading evolutionary paleontologists as they show us how they find rocks of the right ages, discover transitional forms, and reconstruct the environments they lived in. Each film is under 20 minutes in length and specially crafted for classroom use.
