It is located west of Lake Ziway. In addition to the type-site, which assumes the same name, the formation contains a cluster of sites at Kulkuletti, some away. The near-lake environment and locally available obsidian may have attracted the continuous/repeated occupation of the area by Middle and Late Pleistocene hominins. The Gademotta Formation site-complex was discovered in the early 1970s by a team of researchers under the leadership of Fred Wendorf and Romuald Schild.〔F Wendorf, R Schild (1974) A Middle Stone Age Sequence from the Central Rift Valley, Ethiopia. Polska Akademia Nauk, Warsaw.〕 This team conducted several excavations in 1972 and 1973, recovering tens of thousands of stone artifacts. Renewed research in the Gademotta Formation was encouraged by new techniques that allowed for a more precise 40Ar/39Ar age of the site published in 2008.〔LE Morgan, PR Renne (2008) Diachronous dawn for Africa’s Middle Stone Age: new 40Ar/39Ar ages from the Ethiopian Rift. Geology 36: 967-970〕 An age of over 279,000 years old is published for the oldest Middle Stone Age site in the Formation.〔〔Y Sahle et al. (2014) Chronological and behavioral contexts of the earliest Middle Stone Age in the Gademotta Formation, Main Ethiopian Rift. Quaternary International, 331: 6-19. doi.org/10.1016/j.quaint.2013.03.010〕 Although similar in age with the oldest Middle Stone Age site in the Kapthurin Formation, Kenya,〔AL Deino, S McBrearty (2002) 40Ar/39Ar dating of the Kapthurin Formation, Baringo, Kenya. Journal of Human Evolution 42: 185-210.〕 the oldest occupation at Gademotta is characterized by technological elements that are exclusively attributable to the Middle Stone Age. Stone-tipped throwing spears of that age have been studied; they predate known ''Homo sapiens'' fossils.〔 ==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「Gademotta」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.
