Before and after the hiatus

Laguna La Tigra. Un sitio de cazadores-recolectores del Holoceno tardío en el área de Valles Transversales (Provincia de la Pampa)

“…Entre los enteros, principalmente raspadores, se observan evidencias de reactivación y filos embotados. Estas características podrían indicar que fueron descartados in situ al final de su vida útil (Guráieb 2004;Morrow 1997). A nivel general, no se observa una selección de materias primas para la confección de un tipo de instrumento en particular, con la excepción del granito.…”

Andesite and obsidian accessibility and distribution during the Holocene in north-west Santa Cruz province (south-central Patagonia), Argentina

“…Eighteen 14 C dates were used to isolate 5 statistical segregated chronological groups and two temporal blocks divided by a long hiatus of ca. 1000 years in the stratigraphic sequence which seems to be a chronological singularity of CI1 deposit (Guraieb 2004). Abundant archaeological evidence recovered from CI1 stratigraphic layers in nearly 40 m 2 of excavated sediment enabled different intra-site approaches.…”

17 de Marzo (Santa Cruz, Argentina): A new distal source of Pampa del Asador type black obsidian and its implications for understanding hunter-gatherer behavior in Patagonia

“…These designs can be attributed to the Late Holocene in this area (Cirigliano, 2016;Gradin, 2000). In addition, an archaeological site, with pottery sherds and a so-called "Magallanes IV" (Bird, 1988) bifacial stemmed projectile point (Bird, 1988) were also identified close to the wet meadow; the presence of the sherd and the design of the bifacial projectile point suggest that the site belongs to the Late Holocene (Aschero, 1987;Cassiodoro and Tessone, 2014;Cirigliano, 2016;Guráieb, 2000Guráieb, , 2004Franco et al, 2010a;Gradin et al, 1979).…”
