Disclaimers & Credits
Results can be wrong
Identifications are expert-assisted estimates for education and fun. Verify anything important with a qualified expert before relying on it. You are responsible for your own decisions. No outcome is guaranteed, and nothing in Sharktoothify is professional, scientific, appraisal, legal, medical or financial advice.
Tide and weather data is informational only
Tide and weather information is never for navigation, boating, or safety-of-life decisions. Tide alerts are sent on a best-effort basis and can arrive late, not arrive, or be wrong. Always check conditions with official sources before entering the water.
Fossil hunting has real risks and real rules
Your safety, your supervision of minors, and compliance with collecting laws, permits, closures and landowner rules are yours alone. Places lists, the planner and any go score are general information, not permission to enter or collect anywhere.
The species reference and the pictures
The species reference is compiled from the published sources listed with each guide, and each guide shows the date it was last updated. Tooth pictures in the tooth key and the guide are computer-generated illustrations of a typical tooth, and shark pictures are artist's impressions. They are not photographs of specimens and are not evidence for an identification.
