1 EGG - Any dinosaur lover will love these dino fossil egg kits. Each large sized (3" x 2") chalky egg comes with a plastic excavation tool. The kids spend a lot of time chipping away at the plaster to uncover a little plastic dinosaur fossil figurine. These are a great activity for children to do at parties or get togethers to keep them busy. These are great educational toys because they really work the had muscles as the dig up their treasure. Any budding paleontologist would love these, and would make a great dino birthday party favor and game.
