Dinosaurs Before Dark KIDS is an adaptation of the first book in Mary Pope Osborne's award-winning Magic Tree House series. In this show, Jack and Annie are transported back to the time of dinosaurs for a harrowing and exciting adventure in which they courageously learn that things are not always what they seem. The siblings meet many friendly dinosaurs along the way, but must outsmart a truly terrifying Tyrannosaurus Rex if they are to make it back to the tree house and return home to Frog Creek.
