Andy is back at the National Museum, and with the help of his trusty old time-travelling grandfather clock he’s about to set off on an epic journey to visit the dinosaurs and the ice age beasts that once roamed our planet. Helped by his new, tech-savvy assistant Jen and hindered by the accident-prone Janitor, Andy’s adventures stretch across 170 million years of pre-history. Andy comes face to face with ferocious predators, such as the carnivorous Spinosaurus, bigger than a T-Rex; and meets the mighty Argentinosaurus, a 30-metre-long giant, one of largest animals ever to have walked on land. But this time it’s not just dinosaurs on Andy’s sightseeing list: there are also the weird and wonderful beasts that followed in their footsteps – Woolly Mammoths, Sabre Toothed Cats, even our very own ancient relatives, the Neanderthals.
