The "Tricerat Excavations" dinosaur skeleton set from Cass offers young explorers the chance to dive into the fascinating world of paleontology. With this interactive science kit, children can excavate the bones of a Triceratops from volcanic gravel and assemble a complete skeleton. The set not only promotes learning through play but also helps develop important skills as children use special tools to uncover the remains of a dinosaur. Additionally, the little researchers can also excavate a mysterious gemstone, making the experience even more exciting. The use of reusable volcanic gravel that never dries out allows children to be creative and shape their own forms. This set is ideal for kids interested in science who want to gain hands-on experience.
