There's a lot for Thomas to do at the Dinosaur Dig Site! He must find all the fossils and deliver them to the museum. Thomas begins his search on the top loop and finds a fossil in the mountainside.
Turn the mountainside to find the bones, then place the bones into the crane and lower them down to the museum. As Thomas rides to the other side, he causes a landslide, which slides down the track to reveal the dino skull! Place the skull in Thomas' cargo car and bring it the museum.
