 Geology Black shales in the Millstone Grit Series of Namurian Age exposed in the North Bank of the Tees below Ovington. A thin layer of ironstone nodules caps the layer, then a bed of gravel topped by river born silt and turf. A colony of sand martins have made their nest burrows in the silt of the river bank.
 Record Name Ovington. River Tees, North Bank. Black shales and overlying gravels and silt.
 Record Description This bed of black shale or mudstone is unfossiliferous.
 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.
