Late Inka Occupation
The second Inka occupation in the Western Plaza was characterized by the abandonment of the ushnu stone platform. This is signaled by the deposition of a layer of trash on top of the ushnu platform and its surroundings. During this time it is also likely that the gate of the Western Plaza was blocked. There was also a shift in the composition of the ceramics in the midden, considering the increasing dominance of Guarani-Chiriguano

wares, along with eastern lowlands pottery (Figures 7.4. and 7.5). Common in the Guarani tradition, this pottery had a red slip and crushed sherds used as temper (Condorillo Crushed Sherds variant), while other forms were decorated with incisions and fingernail imprints (Parapeti Fingernail variant). Most of the Guarani ceramics were small containers. Among these, globular vessels were the most distinctive. They often had a central body depression and were profusely decorated with fine fingernail impressions. In fact, similar vessels are documented in specialized contexts like Guarani burial areas from Brazil and Paraguay (Brochado Proenza 1973; Esquerdo 1997; La Salvia and Brochado 1989; Susnik 1959).
In Cuzcotuyo, the overall increase of Guarani pottery correlated with the relative decline of the local Manchachi Slate on Red style (Figures 7.6 and 7.7). In the Western Plaza midden, a chi-square test was used to compare the frequency distribution of the distinct ceramic styles from the Early and Late Inka periods. The results revealed that these shifts were, in fact, significant (x2(6)>22.46, p<0.01) (Table 7.1).
After the deposition of this second midden, the area was no longer in use. In the humus layer, we found Colonial remains, such as broken glass

and a piece of an oxidized, handmade iron nail. Therefore, at some point after the collapse and abandonment of Cuzcotuyo, this plaza was still visited in the Colonial era.
