The plot of Unit 9 from Cerro Baúl shows the results of reconstructing smashed vessels from the patio space. Thus far, over 60 vessels have been identified using an “MNI” approach, but not all 60 have been plotted because of the scattering of fragments of some vessels.
Tiahuanaco, Huari, and their Middle Horizon spheres of influence. The map shows the overlap of the two spheres, as well as each capital, important secondary sites, and key geographical areas (in bold text). Drawing by William H. Isbell.
Probable dates for events discussed in text, plotted against currently popular chronologies for Tiahuanaco and Huari. Dates are intended to represent calibrated years (but not Southern Hemisphere corrected). As stated in the chapter text, the date of cal. AD 500 seems too early for the onset of the Tiwanaku Period at Tiahuanaco; AD 650 to 700 seems more likely, at least for the radical changes in ceramics that brought in new vessel forms decorated with new polychrome design themes, as well as the appearance of SAIS-style stone sculptures.
