Recent High Relative Sea Level Stand near Recife, Brazil.
Radiocarbon dates for Vermetidae limestone from the edge of the Brazilian Shield at Cape San Agostinho, Brazil, indicate sea level stands of up to 2.60 meters above the present position, 3660, 2790, and 1190 years ago. Accurate determination of relative sea level is possible because of the well-defined habitat of the fossils dated.
