The Prehysteria trilogy is a trilogy of family-oriente films made in the early to mid-1990s about the adventures of five miniature baby dinosaurs named after musicians. The dinosaurs were Elvis, the Tyrannosaurus Rex, Paula, the Brachiosaurus, Jagger, the Stegosaurus, Hammer, the Chasmosaurus, and Madonna, the Pteranodon. The films were made by Moonbeam Entertainment, the family-oriented sub-brand of B-movie producer Charles Band's Full Moon Entertainment. Richard Band, Michael Bishop, and Fuzzbee Morse composed the music for the movies.
