Pottery recovered from 2012 to 2019 at Nim li Punit, Toledo District, demonstrates that it was occupied from AD 150/250 to AD 830+. We identify long-term changes in the kinds of material produced, used, and discarded over the 600- to 700-year occupation of the site. During the last century of the Classic period, Nim li Punit witnessed a decline in the diversity of ceramic practice. This could reflect a shift in feasting behavior, perhaps due to the political and demographic instability experienced throughout Maya lowlands during the eighth century. Alternatively, this could be the result of new networks of alliance and exchange that arose during this turbulent time. A third possibility is that distinct communities of potters occupied Nim li Punit at different times. To test these different interpretations, we track changes in the ceramic collection at the type: variety level. We discuss similarities and differences seen in the pottery of Nim li Punit and that of other political centers of the Southern Belize Region, and note design and style elements that are shared with other parts of the Maya world.
