Inspired by work conducted by Royal Tyrrell Museum scientists at Dry Island Buffalo Jump Provincial Park, Cretaceous Alberta provides a rare glimpse of Alberta over 69 million years ago. Featuring a family of four Albertosaurus individuals moving across a dry river channel, the exhibit is based on scientific evidence gathered from a mass grave, or bonebed, where at least 12 Albertosaurus sarcophagus skeletons have been discovered.

Albertosaurus was a close relative of Tyrannosaurus.
