At the very end, as Ally and her dad leave the museum, the fossil rock begins to shake and, with only the museum cat watching, the rock breaks apart, revealing a still living, baby Tyrannosaurus.

, and near the town of Brooks. Filming began by capturing the scenes in which Ally Hayden time-travels back to the turn of the century to go on expedition with famous bone-hunter Barnum Brown.

Filming continued for two weeks on location in Dinosaur Provincial Park. Yet the filmmakers faced a challenge in finding a realistic environment to set the live-action filming portion for the Cretaceous period sequences when Ally finds herself wandering amidst the lush vegetation of 65 million years ago. The location used to film Cretaceous period scenes in the end was in the Olympia rain forest in upper Washington state

The special considerations that must be made when working with IMAX 3D presentation also made it crucial that the background features of the shooting locations were ideal.

Besides shooting locations, extensive computer-generated imagery was also employed to ensure the realism of the dinosaurs depicted in the film. Models had to be sculpted and digitized, with details such as texturing crucial to the process. The filmmakers of the next year's television documentary series Walking with Dinosaurs
