Storm Deposits in Tonoloway Limestone

Ancient storms recorded in Tonoloway limestone exposed in the northwest wall of the "Old Derrick" Quarry, along Rt. 50, near Romney, WV. The quarry's late Silurian-aged peritidal carbonates were laid down in the Tippecanoe sea. Its strata primarily record a tidal flat environment, with conspicuous mudcracks, laminites, stromatolites, and salt hoppers within the micritic sediment. Interspersed with these features are coarse layers of lagoonal bioclastics, such as ostracodes and small brachiopods, flung across the flats by passing storms.
