Terrifying pterosaurs, squiggling squid, and massive meteors are all part of the greatest adventure since the Cretaceous period
Thomas's grandparents live in the oldest house on Saurus Street. There's no electricity, and the only toilet is a creaky old cabin in the garden. Thomas is terrified of that toilet. When he gets too close and falls down the hole, he discovers a dinosaur-sized secret that will change Saurus Street forever."
