At this time the Crô-Magnons were also fashioning stronger tools for the engraving of animals in stone, for shallow forms of bas-relief on the walls of the caves, and for other animal outlines. The most evolved animal figures of this period arouse the thought of Magdalenian art in its beginnings. As this industrial evolution widens it is apparent that we witness not the local evolution of a single people but rather the influence and collaboration of numerous colonies reacting more or less one upon the other and spreading their inventions and discoveries. These people were essentially nomadic and no doubt carried the latest types of implements from point to point or bartered them in trade. Thus there is not only a definite succession in such places as Dordogne, but in more remote regions the form of the implements may take on some important differences.(33) There are also other localities where the industry seems for a while to be suspended; thus in the Cantabrian Mountains of Spain we find only the early and the late Aurignacian. Stations similar in culture to those of Dordogne extend northward into Germany and Belgium and eastward into Austria and Poland. Thus the characteristic flint spear heads, known as the _pointe à soie_ and _pointe à cran_ extend from Laussel along the Vézère to Willendorf, in Austria; and the female figures of Baoussé-Roussé (Grimaldi) and of Willendorf represent the same stage of evolution as the large stone bas-relief of Laussel. Again, we observe some relations between the Aurignacian cultures of Austria and of the Italian peninsula, such as the _pointe à cran_, derived from the _gravette_ and found both in various stations of northern Italy and at Willendorf. In western Russia the Aurignacian station of Mezine, Chernigov, shows clearly the types of the superior Aurignacian in the graving of bone and ivory, in the small bâtons recalling those of Spy, in Belgium, and of Brassempouy, in southwestern France, in the large bone piercers perforated at the head, suggesting the primitive needles from the shelter of Blanchard, and in the degenerate statuettes resembling the type of Brassempouy.
