Smithsonian Diggin' Up Dinos T. Rex
Put on your safety goggles, then use a wooden mallet and dowel to carefully chip away at a sand block and unearth dinosaur bones. Use the enclosed brush to remove dust from the block, as you excavate. Then rinse your “fossils” with water and snap them together to form a model T. rex. Includes a 23” x 17” color STEM poster that teaches about the history of paleontology; where and how dinosaur fossils are excavated; extinction theories and more. Ages 8+.
