ABSTRACT In this paper, two new artifacts, a Fishtail projectile (or Fell 1) point and a discoidal stone from central Patagonia, Argentina, are presented. These pieces, mainly associated with the initial peopling of South America, come from an area in which until now no artifacts of this type had been recovered. Both instruments, which were part of the technological equipment of Paleoamericans, are complete. The projectile point is made of light brown translucent opal, and the discoidal stone is made of rhyolite, an acidic volcanic rock. Three-dimensional models of the instruments are presented with the aim of providing a detailed and precise record of both lithic pieces. These archaeological artifacts give information on the geographical distribution of indicators of initial human presence and the use of space during the Pleistocene–Holocene transition in central Patagonia, in the south of South America.
