Shell rings are curved shell middens wholly or partially surrounding a clear central area or plaza. The site includes one of the largest and most complex shell rings in North America,〔Russo:79〕 and one of the best preserved circular shell rings.〔Russo:81〕 ==Environment== More than 30 shell-ring sites are known along the Atlantic coast from South Carolina to Florida. Almost all of the sites date from 4500 to 5000 years ago for the earliest, to about 3000 years ago for the latest.〔One shell ring, the Grand site on Big Talbot Island in Florida, dates to 900-1250 in the Mississippian period. (Parsons:ix)〕 The Fig Island shell rings have been dated between 4400 years ago and 3600 years ago.〔Saunders:47-48, 51〕 The Fig Island site is surrounded by a salt marsh on a peninsula extending from Edisto Island along the North Edisto River. The sea level on the South Carolina coast was as much as 1.2 meters lower when the Fig Island shell rings were built and occupied than it is now. The rise in sea level since then has led to the marsh expanding over what was probably dry land that connected Fig Island to Edisto Island in the past. The Fig Island rings cover an area of 300 by 275 meters.〔Saunders:1, 4, 95〕 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「Fig Island」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
