8. Virginia Fossils Fossils of marine organisms such as clams, scallops, sharks teeth and other hard parts Sand, silt and clay produced by erosion of the Appalachian Mts. covers the plain As sea levels rose and fell, fossils were left at various layers Paleozoic, Mesozoic, and Cenozoic age fossils are found in Virginia
