Unknown fossil one meter below the surface which era did it come from?

To determine the era of an unknown fossil found one meter below the surface, additional context is needed, such as the geological strata surrounding it and the fossil's characteristics. Generally, the depth of one meter could correspond to various geological periods, depending on the location and local sediment accumulation. Fossils found in this range might belong to the Cenozoic, Mesozoic, or even the late Paleozoic, but more specific analysis is required for accurate dating. Geological surveys and radiometric dating techniques can help identify the era more precisely.
