Watch Andy's Dinosaur Adventures Season 1 Episode 18 Online

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' teeth - only, 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!
