This photo displays the fossilized remains of a microscopic snail (center in cross section) and other tiny marine creatures. They were found in a Lawrence County in a section of the Bangor Limestone formation from the Mississippian sub-period of the Carboniferous, about 323 to 359 million years ago. They are all encased in a section of the rock only 0.1 inch (2.5 millimeters) wide.
