Dhar Tichitt : ウィキペディア英語版 | Dhar Tichitt
Dhar Tichitt is a Neolithic site located in the southwest region of the Sahara Desert, in Mauritania. It is one of several settlement locations along the sandstone cliffs in the area. The cliffs were inhabited by pastoralists starting at around 4000 BP and lasted to around 2000 BP. This area is one of the oldest known archeological settlement sites in the western part of Africa. ==Geography== The climate around the Dhar Tichitt region is very arid and hot. However, this was not always the case. Research has shown that the area used to be much more temperate during a time referred to as the Nouakchottian. During this humid phase the area was much more habitable. The Dhar Tichitt region was like this from around 5000 to 3000 before present (BP). During this time the climate was a mixture of two different seasons, a dry season and a shorter rainy season. At around 2500 BP there was a change in the climate and it became too dry for people to stay in the area.〔Holl 2009〕
