Max's father and a paleontologist. Like Max, Spike is obsessed with Dinosaurs and runs the D-Lab. He often wields a whip that often gets caught on things, which are generally things he is not aiming for. Dr. Taylor can also be over-reactive when a dinosaur appears. He also saves the D-Team when the are cornered by the Alpha Gang, and catches the new cards. His name is a pun on "Spike Tail" (AKA: Stegosaurs). He also recaptures the Dino-holders from Seth. In the second season, he, Aki, the Ancients, and the Drakes get captured by Zanjark.
