Andy travels back 127 million years to the time of ornithocheirus - one of the largest flying pterosaurs that ever lived. His mission is to find the skeleton of a sand dollar - a sea creature which spent its life crawling around on the ocean floor. Along the way he comes nose to beak with a tapejaras, a pterosaur which had a beautiful red crest, before taking to the skies on the back of an ornithocheirus. But, will Andy succeed in time before the museum opens?

The show’s own verdict is on its page.
