Downton Castle Sandstone

The Downton Castle Sandstone is a geologic formation in England. It preserves fossils dating back to the Silurian period. As its name would suggest the formation predominantly consists of sandstone with minor siltstone and mudstone.[1] The oldest known Trigonotarbid Palaeotarbus is known from the formation.
