Monsters of the Past: The Story of the Great Dinosaurs

Monsters of the Past: The Story of the Great Dinosaurs (1922) is a documentary film directed by Arthur Sterry Coggeshall.

Produced for the Carnegie Museum, this is one of the earliest dinosaur documentaries. The film includes footage of paleontologists excavating dinosaur fossils in Utah and preparing them for display. Fact cards provide information about various species of dinosaurs. The stop-motion dinosaur footage comes from "The Ghost of Slumber Mountain" (1918) and "Along the Moonbeam Trail" (1920).
