It is a Geological Conservation Review (GCR) site.[1] Location and geologyThe site is located on Alderton Hill to the south west of Dumbleton Wood, approximately 2 kilometres south west of Dumbleton village which is in north Gloucestershire.[1] The site is a significant location for research because of its well preserved Lower Jurassic insect fauna. There is a range of publications which detail the findings on this site, which include fossil insects. Particular findings are specimens of dragonflies (Gomphites) and a large cockroach. Fish remains have been found, and well-preserved cephalopods.[1] The discoveries are usually more complete than those from comparable localities. This is an important paleoentomological locality for research into the anatomy and evolution of early insect faunas.[1] The site is located in hedges which are species-rich. They include ash, oak, holly, hawthorn, hazel and spindle. The common blue butterfly is recorded.[1] References1. ^1 2 3 4 Natural England SSSI information on the citation SSSI Source
