Cadillacs and Dinosaurs is an American/Canadian animated television series which aired on CBS Kids in the United States from 1993 to 1994, lasting for one season of 13 episodes. Based on the comic book of the same name (formerly titled Xenozoic Tales) by Mark Schultz, the show was created by screenwriter Steven E. de Souza, who acquired the TV rights after producing the video game Cadillacs and Dinosaurs, which was also based on Schultz's comic. The show dealt with many strong ecologicial and political issues that were central to the plot development. One major focus was the question of how the dinosaurs managed to re-emerge after they were thought to be extinct.
