The Middle Paleolithic (or Middle Palaeolithic) is the second subdivision of the Paleolithic or Old Stone Age as it is understood in Europe, Africa and Asia.
The Middle Paleolithic or Middle Stone Age (MSA) was a period of African prehistory between the Early Stone Age and the Later Stone Age. It is generally considered to have begun around 280,000 years ago and ended around 50–25,000 years ago.
The Aterian is a Middle Stone Age (or Middle Palaeolithic) stone tool industry centered in the Maghreb, but also found in Oman and the Thar Desert. The earliest Aterian dates to c. 145,000 years ago, at the site of Ifri n'Ammar in Morocco. However, most of the early dates cluster around the beginning of the Last Inter-glacial, around 130,000 years ago, when the environment of North Africa began to ameliorate. The Aterian disappeared around 30,000 years ago and it is currently not thought to have influenced subsequent archaeological cultures in the region.
