The Cretaceous Period was a period in Earth's history when large dinosaurs dominated the landscape, in particular, carnivores like Tyrannosaurus.

It became a time period visited by Biff Tannen while he stole one of the Institute of Future Technology's DeLorean time machines.

Doc Brown, Jules Brown and Verne Brown visited this era to test the Proprietary Ultrasonic Subatomic Molecular Redistributor.

Behind the scenes

In "Forward to the Past", the Cretaceous Period is erroneously stated to be 3 million years BC, which is far from the correct answer: 145 to 65 million years BCE.
