This site exposes Middle Jurassic rocks dating to 174 to 163 million years ago and, in the view of Natural England, it has "the best of most instructive sections" of the period in the Midlands. A Pleistocene fault has caused the juxtaposition of six Jurassic formations.{{cite web|url=http://www.sssi.naturalengland.org.uk/citation/citation_photo/1002784.pdf|title=Cowthick Quarry citation|series=Sites of Special Scientific Interest|publisher=Natural England|accessdate=12 February 2017|url-status=dead|archiveurl=https://web.archive.org/web/20160303225824/http://www.sssi.naturalengland.org.uk/citation/citation_photo/1002784.pdf|archivedate=3 March 2016}}
