LA ESTACIÓN SOLUTRENSE DE LA CUEVA DE AMBROSIO (VÉLEZ-BLANCO, ALMERÍA, ESPAÑA)

The last investigations made during the excavation of the different levels at this important site to study the solutrean in the southeast of the Iberian Peninsula, have permited us to make some precisions on its chronostratigraphic position in the upper pleistocene. The calibration of a new radiocarbon date for the level IV (Upper Solutrean) and other six new dates (5 of them AMS) for the level II (Final Upper Solutrean) allows us to place this two cultural phases between the Greenland Stadial GS3 (end of OIS 3) and the end of the Greenland Intersatial GI 2, with a greater occupation of level II after the Heinrich Event H2, agreeing with the intersadial that come just before the last glacial maximum (GS 2). This new data modify clearly the before existing dates, making the whole record very much older. On the other side, the discovery of decorated panels with engravings and paintings, recoverd by Upper Solutrean sediments, allow us to place this representations, with great precision, in the Medium Solutrean (level VI) that must be placed between the GI 5 and the G 3. The excavation of the area that we call the microstratigraphy, included in level II (Final Upper Solutrean or Evolved Upper Solutrean), has provided 21 double layers of hearts, one of them with a stone structure and thousands of very typical solutrean flint implements that includes the characteristic barbed and tanged points, shouldered points and leaf points. The investigations carried out in the Laboratorio de Estudios Paleolíticos with this arrowheads, shows that they must be thrown with a bow.
