Ash Fell Edge
Ash Fell Edge is a protected area in Cumbria, England, designated as a Site of Special Scientific Interest (SSSI). It is inside the Yorkshire Dales National Park, about 1.5 km northeast of the village Ravenstonedale.
The site is important because its rocks are Carboniferous limestone with fossils in the sediments. These rocks formed about 345 million years ago when the area was the floor of a shallow sea. The rocks include Ashfell sandstone and Ashfell Limestone, which are part of the Great Scar Limestone Group, and they show how sediment built up during the Dinantian period.
Fossils found here include corals from the genus Siphonodendron, bryozoans from Fistuliporidae, and plant fossils such as Archaeosigillaria.
