Beware – the dinosaurs are coming! Guaranteed to excite children’s curiosity and capture their imagination, each stone shows a dinosaur footprint on one side and its owner on the other. Perfect to encourage early investigation skills as children examine, compare and sort the eight footprints: Apatosaurus, Deinonychus, Hypsilophodon, Iguanodon, Quetzalcoatlus, Stegosaurus, Triceratops and Tyrannosaurus Rex. Children will enjoy making crayon rubbings, impressions in play dough, footprint trails and comparing the different shapes of the footprints. Made from non-toxic unique stone mix, they are durable for use both inside and outdoors. Contains 8 double-sided stones (3 ½ x 2 ½ inches).
