Lots of Fossils

The outcrop (rocks visible on the Earth's surface) you see here is the Grier Member of the Lexington Limestone. Note the position of this member on your stratigraphic column. When you first observe this outcrop you should notice different layers. That is because there are alternating beds of limestone and shale which have different weathering patterns. The shale is more easily eroded, which leaves the limestone beds sticking slightly out of the outcrop. Now if you step up close to the outcrop, you'll notice that it is loaded with fossils. The fossils found here are primarily gastropods (snails), brachiopods (look like clams, but aren't), and bryozoans (moss animals - look like coral).
