The Magdalenian is largely defined by its diverse array of sophisticated osseous projectile weaponry. Found throughout Western Europe, Magdalenian assemblages include antler points hafted using a variety of technological designs, unilaterally and bilaterally barbed points, self-barbed points, bivalve points made of two half round rods (baguettes demi-rondes), and composite antler/lithic projectile points, not to mention foreshafts and spearthrower elements. As perhaps the richest assemblage of osseous projectile weaponry manufactured during the Pleistocene worldwide, a thorough understanding of this technology is essential for building a cohesive understanding of not only the technological choices made by hunter-gatherers in Western Europe during this period, but the wider economic and social role that osseous projectile technology can play in a Pleistocene age culture. This chapter aims to outline the diversity of Magdalenian osseous projectile weaponry as well as its evolution throughout the period 21,000 – 14,000 cal BP. How these implements were designed, manufactured, used, and maintained is described.
