Xenozoic Tales is a comic book series by Mark Schultz set in a post-apocalyptic future. Publication began in 1986 with the story "Xenozoic!" included in the comic anthology Death Rattle. This was shortly followed by Xenozoic Tales #1 in February 1987.

Cadillacs and Dinosaurs: The Arcade Game is a 1993 arcade game released by Capcom, a side-scrolling beat-em-up, based on the comic book series, starring four characters: Jack Tenrec, Mess O'Bradovich, the lovely Diplomat and Explorer Hannah Dundee and Mustapha Cairo.

Cadillacs and Dinosaurs is an American Saturday morning animated television series which aired on CBS Kids in the United States from 1993 to 1994. Based on the comic book series 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. Cadillacs and Dinosaurs lasted for only one season consisting of 13 episodes.

A short lived line of Cadillacs and Dinosaurs toys based upon the Animated Series was produced by Tyco Toys in late 1993. The line featured action figures of the principle cast, along with a few dinosaurs (reissued from the previous Dino-Riders line), and finally a couple of vehicles. Out of all the accessories, figures and vehicles in the line, by far the one most fans and collectors will remember is Jack Tenrec's Cadillac... which was a trademark staple of the entire line. A playset of Jack's Garage was advertised but never produced.
