Dietary Stress and Animal Resource Use at the Postclassic Maya city, Mayapan (Mexico)

Environmental changes resulting in drought and reductions in the availability of animal resources during the Late Classic Maya have been linked with the Maya 'collapse'. Decreases in availability of dietary staples such as artiodactyls, and particularly white-tailed deer, during the Late Classic period would have placed food stress on populations during later periods. To test this hypothesis, here bone breakage patterns are examined at the Postclassic Maya city, Mayapn, to assess whether artiodactyl bones were being intensively processed for bone fats (marrow and grease). Fragmentation morphology, size and surface markings, along with skeletal part representation and distribution of large mammal bones were recorded for bone assemblages from several houselots. Evidence suggests the Maya were likely utilising bone marrow from artiodactyls but not intensively and they were not extracting bone grease. These results indicate that decreased accessibility to artiodactyls during the Postclassic was not causing high levels of dietary stress for the Maya at Mayapn, which is consistent with recent evidence demonstrating dietary consistency during the Postclassic in northern Yucatan.
