Fossilr AI: Fossil ID · private field key
Is this a fossil or a lookalike?
Open your photo locally, record the strongest visible structure and preserve the geologic context. The result stays broad because one image cannot confirm a fossil or species.
Broad result
Possible fossil candidate
Look for repeated anatomical structure, a geologic context, several matching views and comparison with a regional reference collection.
Shape choice: organized but imperfect. A photo cannot confirm a fossil or species. Keep location and scale with every image.
