The main characters include Littlefoot (Apatosaurus), Cera (Triceratops), Ducky (Saurolophus), Petrie (Pteranodon), Spike (Stegosaurus), and in the spin - off television series and the fourteenth movie, Chomper (Tyrannosaurus) and Ruby (Oviraptor). Other characters include the families of the main characters, the residents of their home, the Great Valley, and outsiders to the Great Valley . </P> <P> The idea for The Land Before Time came during production of An American Tail . Steven Spielberg's studio Amblin Entertainment was interested in doing a film about dinosaurs, which were popular at the time, leading Spielberg, director Don Bluth, and producer George Lucas to develop the prehistoric setting and its cast . Inspired by the dinosaur - themed "Rite of Spring" sequence from Disney's Fantasia, Spielberg had originally intended for the movie to have no speech, with music queues and body language telling the story, effectively rendering all the characters mute . However, it was decided that the film couldn't carry a story without dialogue, and each character was given language accordingly . Despite this, the film's artists would still use the Fantasia sequence and characters as guides when creating their the very first concept art . </P>
