Puntas de proyectil líticas de la cuenca media e inferior del río Coyle (Santa Cruz): aportes al uso del espacio regional y a la distribución espacial del diseño Magallanes IV

The technological analysis of 39 lithic projectile points from the middle and lower basin of the Coyle River is introduced. Five technological subgroups manufactured on local high availability raw material are identified. Points were abandoned with high resharpening potential, the ones from throwing weapon systems predominate and 31 were related to the Magallanes IV design. The data complements discussions on landscape use by Late Holocene hunter-gatherers and incorporates the Coyle River basin within the supraregional distribution of the Magallanes IV design. Results reinforce the statement about the continuous spatial distribution of this point design from the Magellan Strait to the North of the Santa Cruz River.
