The quarries are wholly within the North Yorkshire and Cleveland Heritage Coast and partly within the North York Moors National Park and the historic North Riding of Yorkshire. The fossil content of Boulby Quarry is particularly important with two plesiosaur species (''Eretmosaurus macroptera'' and ''Thaumatosaurus zetlandicus''), an ichthyosaur ''Ichthyosaurus crassimonus'' and the only Upper Lias pterosaur known in Britain, Parapsicephalus being found at the site. The fossil are found in the ''bifrons'' zone, and although not abundant, it is very different from surrounding fossil sites.〔(【引用サイトリンク】 work=Natural England )〕 ==References== 〔 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「Boulby Quarries」の詳細全文を読む スポンサード リンク
