Buried Treasure Fossils offers wonderfully preserved early Eocene shark teeth were found in exposures along a creek bed (Muddy Creek / Fisher - Sullivan site) in northeastern Virginia. The site provides an exceptional snapshoot in time about 54 million years ago with an early Eocene sea full of shark, ray, fish, and other fossils. These teeth were found in the Bed B Potapaco Member of the Nanjemoy Formation. Note these teeth exhibit exceptional preservation and condition. Great collector's teeth. The state published a great reference book on this site: Weems.R.E. and Grimsley, G.J., "Early Eocene Vertebrates and Plants from the Fisher / Sullivan Site (Nanjemoy Formation) Stafford County, Virginia", Virginia Division of Mineral Resource, Pub. 152.

Note - The Muddy Creek / Fisher - Sullivan site was once a collector's paradise for those who had access. Now it is lost forever as the collecting area is buried under a new housing development. There has been no exposure of the fossil bed since the mid-2000s. Another famous collecting site "bites the dust." But there is limited material available to you from old collections.
