An Allosaurus terrorizes various dinosaurs until it gets its comeuppance by a Styracosaurus. Then the Styracosaurus is killed by a T-Rex. A fire in the Mesozoic era sends everyone running.
“Prehistoric Animals” was released in 1938. It is a silent ten-minute short film created by the University of Kansas as an educational film. The movie is basically various scenes from the 1925 silent film “The Lost World” directed by Harry O. Hoyt and animated by Willis O’Brien. In some of the scenes you can see the actors from the original 1925 film at the bottom of the screen.
Professor of Geology, Raymond C. Moore and Professor of Zoology, H.H. Lane reconfigured the scenes and added intertitles to explain the various dinosaurs depicted.
The film is purported to show a typical day in the life of the Mesozoic era. The university received permission from Kodascope Libraries to use the footage. The film has since come under public domain.
There’s a glitch in the film. At a little over five minutes into the film, it reverts back to where the brontosaurus fell off the cliff. It then goes forward again from there.
The dinosaurs shown in the film were Allosaurus, Brontosaurus, Pteranodon, Stegosaurus, Styracosaurus, Trachodon, Triceratops, and Tyrannosaurus Rex.
