Children's dinosaur history series. Andy travels back 150 million years and all the way to North America, the home of stegosaurus.
Andy travels back 150 million years and all the way to North America, the home of stegosaurus - a five-tonne plant eater that was as long as a double-decker bus! Stegosaurus were covered in armoured plates that they flushed blood into when they were angry to scare away meat-eating dinosaurs like allosaurus. Andy's mission is to get a photograph of the plates of an angry stegosaurus so he can finish Hatty's painting back at the museum - but will he make it back in time, especially since a hungry allosaurus is never far away?
