When the general geographic distribution of the Aurignacian (Fig. 153) is compared with that of the Mousterian (Fig. 125) it is surprising to find how many of the stations are identical; it would appear as if the Crô-Magnons had driven the Neanderthals from their principal stations over all of western Europe for the pursuit of their own industries and of the chase. We have already spoken of the invasion of the Mousterian stations along the Riviera, in the Pyrenees, in the Cantabrian Alps, and along the Dordogne and the Somme; this occupation also extends along the Meuse, the Rhine, and the Danube; but, whereas there are only six stations in all Germany of unquestioned Mousterian age, there are more than double that number in Aurignacian times. The Crô-Magnons entered the grottos of Sirgenstein and Räuberhöhle, near the headwaters of the Danube; northwest of Sirgenstein they established the open 'loess' station of Achenheim, west of Strasburg; in the lower layers of the 'newer loess' was also the station of Völklinshofen, south of Achenheim; along the middle Rhine were the 'loess' stations of Rhens and Metternich, and to the far north, close to the borders of the Scandinavian glacier, was the somewhat doubtful Aurignacian station of Thiede. The Crô-Magnon men entered the Sirgenstein grotto and scattered the implements of their culture above the 'lower rodent layer,' composed of the Obi lemming, and also left remains of the woolly rhinoceros, the woolly mammoth, the stag, and the reindeer on the floor of the cavern. The Upper Aurignacian also extends down the Danube as far as Willendorf, and possibly to Brünn, Moravia, which last, however, may be of Solutrean age. Altogether between seventeen and twenty Aurignacian stations have been discovered in the region north of the Danube and along the Rhine. [Illustration: FIG. 153.
