The Suwannee Limestone, is a white to cream, fossiliferous, Lower Oligocene (see time scale) marine limestone. Dolomitized portions of the unit are gray, tan, light brown to moderate brown, dolostone with limited occurrences of fosiliferous (molds and casts) beds. Silicified limestone, in the form of chert, is common in Suwannee Limestone.   It occurs near the surface in the eastern panhandle, northern peninsula, and in portions of west central Florida. Fossils present in the Suwannee Limestone include mollusks, foraminifers, corals and echinoids.  Classic exposures occur along the Suwannee River in Suwannee and Hamilton Counties.
