In the EARLY MAGDALENIAN we note the invention of the _harpoon_; its first crude form is that of a short, straight point of bone, deeply grooved on one face, the ridges and notches along one edge being the only indications of what later develop into the recurved barbed points of the typical harpoon. As noted above, this invention was destined to exert a very strong influence on the habits of these people. Large fish undoubtedly were very abundant in all the rivers at that time, and this new means of obtaining an abundant food supply probably diverted the Crô-Magnons in part from the more ardent and dangerous pursuit of the larger kinds of game. The discovery soon spread, and among a number of localities where prototypes of the harpoon are found may be mentioned Placard, in Charente; Laugerie Basse, in Dordogne; Mas d'Azil, on the Arize; and Altamira, in northern Spain. In the early Magdalenian also a great variety of flint drills or borers are developed in connection with the fashioning of bone, including the 'parrot-beak' type, or recurved flint. The microlithic flints, exclusively designed for fine and delicate artistic work, are more abundant than in any previous stage, and were used to shape and finish the bone implements which chiefly distinguish the Magdalenian culture. Other implements which enable us to recognize the early Magdalenian culture layers are javelin points of bone or reindeer-horn with oblique bases, small staves of reindeer-horn or ivory, oval plates of bone frequently decorated with engraved designs, and slender, finely finished needles.
