Local and Guarani Pottery Distribution
The pottery of the early midden in both plazas had a dominance of the local Manchachi Slate on Red style, in addition to utilitarian wares. As discussed, other ceramics from the eastern tropics like the Condorillo Crushed Sherds were minimally represented (Figure 7.4). In the second occupation, after the ushnu fell into disuse, the Western Plaza exhibited a radical shift in the ceramic assemblage. Along with the decrease of the early Manchachi Slate on Red ceramics, there was a marked increase in pottery with Guarani or tropical origins. All these Guarani ceramics had crushed sherds in the paste as temper. They were also decorated with fingernail marks (Parapeti Ungulate), digital impressions, and incisions in different shapes, and some were even covered with a red slip on the surface (Condorillo Crushed Sherds). Other examples had corrugated and brushed exteriors (Figure 7.4).
At a spatial level, we corroborated that the two main areas with considerable amounts of ceramic remains were the two plazas. The rest of the rooms held few utilitarian sherds. Both plazas had also the largest variety of ceramic styles in the whole complex, particularly in the Eastern Plaza (Table 7.3; Figure 7.16). By comparison, the military barrack held an abundance of utilitarian wares with local and altiplanic technology, supplemented by a low proportion of local Manchachi Slate on Red wares (Table 7.3; Figure 7.17). Considering that this local variant was also found in the early levels of the plaza midden and the adjacent residences and warehouses, its ubiquitous presence signals their use by indigenous frontier populations.
