Based primarily on historical sources subject to interpretation, it has been suggested that llama caravans may have reached the southeast of South America during Pre-Columbian times, particularly to the northern Pampean region and the Paraná River valley. While the archaeological assemblages in these two areas include camelid bones that have thus far been identified as guanaco (<em>Lama guanicoe</em>), the possibility of misidentification due to the osteometric similarity between the latter and <em>L. glama</em> could mask the presence of domestic camelids in the record, undermining evidence of this potential major expansion of Andean caravans and domestic camelids.

Scanning electron microscopy (SEM) was employed to examine silicone impressions of drill holes made from these beads. This served to document the characteristic tool marks used to perforate the Keros and Dhaskalio beads. When compared to the SEM images of experimentally-reproduced drillings and those from beads whose drilling agents have already been identified, the identification of the types of drills used was possible. Since different production methods and drilling styles are diagnostic of different regional craft traditions it was then possible, using an interregional comparative study, to suggest the workshop traditions of origin for these beads. Results indicate that long distance import was likely for most of these beads while two may have been produced more locally in Anatolia. Of special significance is the one carnelian bead from Dhaskalio that we demonstrate derived from the Indus Valley craft tradition, perforated with a distinctly Indus-style drill and made in a shape common among Indus-affiliated beads.
