Most of the time I pick up or dig sharks teeth in a creek near the Rappahannock River but I found it was mostly sanded in when I went to look. Did find a hole in the side of the creek where seashells were stacked with water flowing through, removing most of the silt (and depositing many teeth and other fossils in front of the hole). The bottom layer was hard gray clay, few if any shells. The second layer was a fragile heavy white triangular shell (or impression from a long-gone shell. Above these the shells seemed more jumbled and less distinct layers, but contained lots of very flat shells, scallops, curved oyster-like shells, a straighter oyster-like shell with distinct growth(?) sections, and lots of clams and barnacles. (One shell was partly covered by a layer of coral-- but doesn't really show in the scans). Most of the shark teeth seemed mixed in the jumbled layer. I'm curious about the fossil seashells but wonder if they can provide the era and period where the shark teeth and other fossils come from. Except for the flat shell and maybe the triangular white one, the shells don't scan well but I'm hoping some of you can recognize them despite the poor pictures. (Having trouble loading but will add others ).

Some units in the Pennsylvanian Lansing and Kansas City Groups of the Kansas City metro have characteristics that aid in stratigraphic identification: Eudora Shale - Black & platy shale Captain Creek Limestone - * Enteletes brachiopods common Farley Limestone - Osagia in upper part Liberty Memorial Shale - Siderite concretions Muncie Creek Shale - * Phosphatic concretions; black and platy shale Cement City Limestone - * Large horn corals (Caninia torquia) Quivira Shale - Black & platy shale in places Wea Shale - Siderite concretions in a few spots Wea Shale - * In lower part, hash with Crurythris brachiopods and ammovertellid forams. Winterset Limestone - * Dark bluish gray to black chert Stark Shale - Black & platy shale Bethany Falls Limestone - * Massive, bus-sized blocks on weathered outcrops Hushpuckney Shale - Black & platy shale Middle Creek Limestone - * Meekella brachiopods common ----- Asterisk (*) for particularly diagnostic features.
