Le « Moustérien » de Tipasa et de Ténès (littoral ouest algérois) dans la lecture climatique du second pléniglacaire

Abstract

The excavations that we undertook, in 1985, in the prehistoric site of Sidi Saïd, in Tipasa (Algeria), allowed us to observe an unusual archaeological stratigraphy. An aterian industry with pedunculated pieces, surmounted by a Mousterian, rich in scrapers and single-sided retouching points, almost systematically in flint, with reduced shapes and strongly reduced (Aterian under Mousterian). This unusual case has led us to consider the reading of the Mousterian-Aterian/Ibéromaurusien passage in a different way and at the same time to take a new look at the work carried out so far on the west coast of Algiers, especially those of Lower cave of the Tenes lighthouse, west of Tipasa. An attempt to compare and correlate the site of Sidi Said and the Lower Cave of the Ténès lighthouse, enabled us to consolidate our conviction on the existence of an aterian stratigraphically below the Mousterian and to discover an original lithic industry of Mousterian tradition, with strongly reduced forms, which would be placed between stratigraphically between the Aterian and the Iberomaurusian. This industry which does not yet have a name or place in the chronology, “curiously” recalls the case of the Middle Solutrean of southwestern Europe, in the context of the second pleniglacial.
