Overview

Isotope analysis reveals dietary patterns and mobility in populations during Postclassic conflicts, suggesting ritual violence linked to two dominant polities.

Key Points

  • Isotope analysis of human remains indicates distinct mobility patterns during periods of political conflict and violence.
  • The analysis includes isotopes of strontium, oxygen, and carbon from human tooth enamel at two sites in Guatemala.
  • Excavations reveal ritual violence, with burials representing social unrest and conflicts between Itza and Kowoj polities.
  • Findings suggest local and non-local origins of individuals, with distinct burial practices linked to the tumultuous political landscape.
