Fossil limestone rock.
Limestone ( calcium carbonate CaCO3) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of CaCO3. Limestone forms when these minerals precipitate out of water containing dissolved calcium.The limestone is a natural sedimentary rock formed from coral, algal, and fecal accumulation and includes many fossils and tiny fossilized organic debris and shell fragments.

This will prevent uneven splits or cracked rock. As the layers begin to separate, you will see an even split along the length of the stone. Proceed slowly to prevent uneven splits or fractures.
The fossil debris of coquina is composed of calcium carbonate, making coquina a variety of limestone. Coquina contains very little silt or clay-size particles, and its fossil fragments are lightly cemented together. This makes it an extremely porous rock that can serve as an aquifer for community and private water supplies.
A fossil is the remains, trace, or imprint of an organism (animal, plant, etc.) that has been preserved in the earth's crust (usually in rock) since some past geologic time.
