Thomas and the Dinosaur is a book. It was re-released in 2015 with new illustrations.
Percy is chuffing back to the sheds when he suddenly sees a dragon-like creature. Startled by this, he tells Thomas all about it. Later, Thomas sees the same thing, but is eventually corrected by his driver that the "dragon" is really a dinosaur model. The Fat Controller orders Thomas to take the model to the new dinosaur park.
