Perfect for your budding archeologist, this block set features 32 fossils. Each block is handcrafted in the U.S.A. and features the fossil place, time period, era, and rock layer. Ready to illuminate and help teach children science and fundamental skills, this block set is classically used as a directive toy, but we prefer to combine them with other blocks shapes and colors for open-ended play. Mixing them up offers both science knowledge and imaginative possibilities to encourage organic learning. See and feel 32 fossils!
