The excavation unit A02-26u1 at Taukamayo presents lithic evidence, albeit synchronic to the Tiwanaku period, that is, in some ways, representative of the material use pattern in Block 3 overall. Distinct patterns emerge, however, with respect to the use of Ob2 obsidian, because as was noted Ob2 obsidian was rarely used outside of Block 3.

Table 7-34. A02-26u1 Excavation and Block 3 surface: Lithic Tech. Classes by Obsidian type.
Table 7-34 shows that Ob1 obsidian was primarily used for projectile point production, however bifaces from Ob2 were used to a much greater extent at A02-26u1. Retouched flakes of the two material types were used in similar proportions in the two contexts.
