This article addresses Postclassic Maya population recovery in the aftermath of the collapse of Terminal Classic period political centers by 1100 CE in northern Yucatan, Mexico. While much has been written about the collapse of northern lowland Classic period Maya civilization by the eleventh century CE, we focus here on longer-term outcomes from a demographic perspective, during the Postclassic period (1150-1500 CE). We analyze survey data from the adjacent and sequential archaeological sites of Tichac and Mayapán to support three arguments. First, rural zones were populous prior to the northern collapse. Second, inhabitants of rural zones persisted during the cycle of political collapse and recovery. Third the ubiquity of Postclassic Maya settlements after the twelfth century CE suggests resiliency in the region marked by a rapid rate of sociopolitical regeneration and substantial (if partial) demographic recovery. We frame findings from our study area with broader evidence from regional archaeological settlement studies and early Colonial documents attesting to robust northern Maya populations at the time of European contact. We consider the important role of rural localities in fostering recovery by storing cultural knowledge, providing destinations for outmigration, and serving as hubs for long-term, cyclical regeneration of state society.
We investigate archaeological evidence for the early production of Melo (or commonly named ‘baler’) shell knives recovered from Late Pleistocene and Early Holocene deposits in Boodie Cave, Barrow Island. The site is in the Country of Thalanyji people in northwestern Western Australia. The oldest shell knife fragments were recovered from units dated to 46.2–42.6 ka, making this one of the oldest Homo sapiens sapiens shell tool technologies currently described. We situate this early and ongoing tradition of shell tool manufacture within recent discussions of the early development of shell industries from both Island Southeast Asia and globally. Although shell knives have been previously reported from Pilbara and Gulf of Carpentaria surface middens in northern Australia, systematic analysis of the manufacturing process and associated debris, and especially from pre-Holocene contexts, has not been previously conducted. This research explores the shell knife chaîne opératoire through the integration of three data sets derived from archaeology, ethnography, and experimental archaeology. This study highlights the significance of shell tool industries in the northwest of Australia, and globally, from the Pleistocene and into the Late Holocene in areas with limited access to hard rock geology where shell reduction represents a unique technological strategy.
