Young explorers will have loads of fun as they bury these realistic prehistoric teeth in sand, mud or other sensory bases and then use paint brushes and spades to ‘excavate’ them. They can build on their fossil and dinosaur knowledge and vocabulary as they match the teeth to the different dinosaurs, measure them and compare characteristics and investigate the world they inhabited. This set of 8 durable teeth stones includes: Allosaurus, Iguanodon, Mammoth, Pliosaur, Ptychodus, Stegosaurus, Triceratops and Tyrannosaurus-Rex. Max length 105mm. Age 2 years+
