Rock Layers and Fossils
Gravel, sand, and mud sink in water to form layers. Newer layers build up on top, 🪨 so deeper layers are older! Tap a layer to see its order. ⛏️ In the Fossil Dig tab, clear the dirt to uncover trilobites, ferns, fish, ammonites, dinosaur footprints, and shells. Discover if they lived in the sea or on land as you fill your guide! 🎯 Try the Challenge to test your knowledge of layer order and habitats. Supports 7 languages.
