Classic Maya burials are complex archaeological contexts, shaped by distinctive depositional and postdepositional activities. To address this complexity, mortuary archaeologists have increasingly adopted theoretical and methodological frameworks from archaeothanatology. This article applies an archaeothanatological approach to the analysis of 35 burials from Group IV, a nonroyal elite residential compound at the Classic Maya site of Palenque, Mexico. The study reveals a complex funerary sequence that includes predepositional body preparation, primary and secondary depositions, and postdepositional modifications, reflecting long-lasting relationships between the living and the dead. The results provide evidence for differential treatments. Protracted rituals were conducted around elaborate burials, although they rarely included secondary skeletal manipulation. Conversely, simpler stone graves underwent reopening and secondary manipulation, and a few individuals were buried directly into the soil. Despite their differences, these activities were materializations of beliefs, which underscored the centrality of ritual interaction with the dead in Classic Maya mortuary traditions. These patterns mirror broader ritual traditions at Palenque that involved the prolonged usage of ritual spaces and burials, as well as concerns about corpses’ decay.
