Dennis Deinocheirus

Dennis Deinocheirus is a minor character in the children's animated series Dinosaur Train.

Character creation
Dennis was created in cooperation with the Centers for Disease Control and Prevention (CDC) for their "Learn the Signs. Act Early" initiative. This initiative encourages parents to track their children's developmental milestones, so that developmental disabilities can be detected early and given the appropriate support. A child psychologist was brought on board as a script advisor.
