What is "prehysteria!"

Prehysteria! is a series of three family-oriented, non-horror, monster movie films made in the early to mid-1990s about the adventures of five miniature baby dinosaurs named after famous pop musicians. The dinosaurs were Elvis, a male Tyrannosaurus Rex, Paula, a female Brachiosaurus, Jagger, a male Stegosaurus, Hammer, a male Chasmosaurus, and Madonna, a female 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.
