Max's best friend. Rex was found as an infant by paleontologist Dr. Owen, in an egg-like container within a dinosaur exhibit in New York. Rex is now 12 and has been left with Max and his family (Dr. Owen being a family friend) while his father goes searching for fossils. It is revealed in one episode that Rex was left at Max's house because his father wanted him to be near a real family. Rex's partner is a Carnotaurus he named Ace. Rex is a good-hearted boy and is relatively quiet, but also quite short-tempered from the beginning. At the end of the first season, it is revealed that his real parents are Dr. Ancient and Dr. Cretacia and Rex reunites with them. In the finale, Rex, the Alpha Gang, Seth and the Ancients go to the future.
