Prehistoric Beast is a ten minute long experimental animated film conceived, supervised and directed by Phil Tippett in 1984. This sequence is considered to be the first film produced by the Tippett Studio, founded by Tippett himself in 1984. Made with the go- motion animation technique, the story takes place during the Cretaceous period and follows a Tyrannosaurus as she chases and preys upon a Monoclonius.
