Children's dinosaur history series. Andy travels back 220 million years to the time of postosuchus - a giant crocodile-like creature.
Andy travels back 220 million years to the time of postosuchus - a giant crocodile-like creature that roamed North America in the time of the earliest dinosaurs. Before dinosaurs came along, he was the biggest meat eater on the planet, with a set of teeth to be proud of. So much so, in fact, that Hatty's display is all about the postosuchus's teeth - except they've all gone missing!
Andy's mission is to track down a postosuchus and make himself some plaster copies of its teeth. Not an easy task, given it would happily take a bite out of him given half a chance!
