| Additional Notes | These shales are usually unfossiliferous however the crowded remains of brachiopods, trilobites, bryophytes (Fenestrella sp.) and other fossils are occasionally found in thin calcareous marine bed bands and at at the base of thick beds of these shales.
Where marine shale bands outcrop in Upper Swaledale, sepages of calcium rich groundwater form tufa deposits with rich flora of high botanical interest.
