Dinosaur Train centers on a young Tyrannosaurus Rex named Buddy (voiced by Phillip Corlett) and his adoptive Pteranodon family, who live in a giant nest near the sea. Inquisitive Buddy is always on the lookout for adventure, and there's no shortage of it when he and his siblings Tiny (Claire Corlett), Shiny (Erika-Shaye Gair), and Don board the Dinosaur Train and speed through time to meet other prehistoric creatures. As questions arise, Buddy comes up with theories and eagerly makes discoveries that will solve the scientific riddles he faces. The show also includes live-action segments starring paleontologist Scott Sampson, who chats with kids about science and fun dinosaur facts.
