The Gobero archaeological site, dating to approximately 8000 BCE, is the oldest known graveyard in the Sahara Desert. The site contains important information for archaeologists on how early humans adapted to a constantly changing environment. Gobero is located in the Ténéré desert of Niger, and is named after the Tuareg name for the region. ==Site== The area was once the location of a paleolake named Gobero, filled with approximately three meters of fresh water, 3 km in depth.〔 There are eight sites that make up Gobero: G1, G2, G3, G4, G5, G6, G7, and G8, five of which (G1, G2, G3, G5, and G8) have funerary and habitation remains.〔 Site G1 is a dune that that rises from the lake basin to an elevation of 56.035m above sea level and extends east-west.〔 It contains 19 excavated burials, 20 individuals in total.〔 Site G2 is a hill between Site G1 and 3 that contained four burials.〔 G3 is 300 meters Northwest of G1 and contained 48 burials with 51 individuals total.〔 Site G8 is 6.5 km West of G3 and contained some human burials as well as lithic artifacts and pottery.〔 The time frame of the site has been divided into four phases: Phase I dates from around 14,000-7700 BCE and is characterized by weakening monsoons and the aridification of the area, which created the earliest paleodunes at the site, Phase II dates from 7700-6200 BCE and is characterized by a wet climate and the first evidence of occupation by a fisher-gatherer group known as the Kiffians. The next phase is an interruption in the occupation of the site from 6200 BCE – 5200 BCE due to the return of dry and arid conditions making the site uninhabitable.〔 Phase III dates from 5200 BCE to 2200 BCE, and is characterized by the second main occupation of the site at Gobero by a group known as the Tenerians.〔 The final Phase, Phase IV, dates from 2500 BCE to 300 BCE and is the period in which the Sahara dries out once more, ending any occupation.〔 A wealth of lithic artifacts were recovered from sites G1 and G3, though most came from the surface. A total of 4,685 artifacts came from G1 and 11,503 came from G3.〔 These included cores, blanks, endscrapers, perforators, burins, backed tools, notches, denticulates, truncations, geometric tools, sidescrapers, arrowheads, tenerian disks, bifacial tools, axes and adzes, grinding stones and polished axes and other retouched tools.〔 4,646 potsherds were collected during excavations in 2005-6, all from G1 and G3. Vessel shapes were open and closed bowls and jars.〔 Types of decorative techniques for the pots included rocker stamping, mainly found at site G1, decorations with cord-wrapped tools, and decorations made with combs.〔 Some decoration styles included plain zigzags, straight zigzags, curved zigzags, zigzags that form fishnet patterns, and dotted zigzags.〔 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「Gobero」の詳細全文を読む スポンサード リンク
