Explore 100 excavation puzzles across five geological regions. Discover ten fossil forms, fill the specimen cabinet, and preserve each find with brush, chisel, and scan tools.
Read the stone. Unearth fossils across 100 careful excavation puzzles.
There is something beneath the stone. Read the survey, choose your tool, and reveal a fossil one careful square at a time. Brush away layers safely, use a chisel when speed matters, or spend a limited scan to learn what lies nearby. A careless strike can fracture your find. Finish each excavation, earn a preservation grade, and keep your discoveries in a growing specimen cabinet. Explore 100 excavation sites across five distinct geological regions and discover ten fossil forms. Later surveys have larger grids and tougher stone. Your progress and best preservation grades stay on your device. Fossil Folio is a complete one-time purchase. All sites are included.
