A scientist dreams of prehistoric monsters. He awakes in a cavern. A dinosaur chases him, even though he tries to shoot it with his revolver. The chase continues onto the surface. The professor meets a group of prehistoric women, who flee when other monsters appear. The professor's wife finds him sleeping in the laboratory, surrounded by fossils, and wakes him with water from a siphon. Its generally believed to be the first film depiction of dinosaurs, here accomplished through the use of simple pantomime costumes. This short film was only viewable at the BFI until youtuber coldcrashpictures paid money to release it digitally on his channel.
