Alderton Hill Quarry () is a geological Site of Special Scientific Interest in Gloucestershire, notified in 1997. It is a Geological Conservation Review (GCR) site.〔(Natural England SSSI information on the citation )〕 ==Location and geology== The 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.〔 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.〔 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.〔 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.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Alderton Hill Quarry」の詳細全文を読む スポンサード リンク
