Commingled and Mass Burials

Commingled and mass burials contain the mixed remains of many individuals, requiring methods to count and re-associate skeletons and to interpret why so many people were buried together.

Definition

The analysis of burial deposits containing the mixed or disarticulated remains of multiple individuals, including methods for estimating their number, re-associating elements, and interpreting the circumstances of deposition.

Scope

This topic covers the analysis of deposits where skeletal elements from multiple individuals are mixed or disarticulated: quantifying the number of individuals, re-associating elements, and assessing demography, alongside the interpretation of mass graves arising from epidemic, massacre, warfare, or collective tomb use. It combines rigorous quantitative osteology with contextual and taphonomic interpretation.

Core questions

• How is the number of individuals in a commingled deposit estimated?
• How can disarticulated elements be re-associated into individuals?
• How are mass graves distinguished and their causes—epidemic, massacre, ritual—interpreted?
• What demographic and taphonomic information can commingled assemblages yield?

Key theories

Quantifying individuals from commingled remains

Adams and Konigsberg's likelihood-based approach to estimating the number of individuals represented by commingled bones, refining the long-used minimum-number-of-individuals count with statistical and pair-matching methods.

Context-driven interpretation of mass deposits

The principle that the meaning of a multiple burial—from epidemic catastrophe to deliberate collective tomb use or massacre—depends on integrating skeletal demography and trauma with taphonomy and archaeological context.

History

Counting and analyzing commingled remains has long relied on the minimum number of individuals, but statistical methods such as Adams and Konigsberg's most-likely-number-of-individuals and pair-matching improved estimates. Edited syntheses, including Osterholtz and colleagues' volume, advanced shared theory and methods for disarticulated and mass-burial assemblages.

Debates

Counting individuals and interpreting mass graves

Debate over which quantification methods best estimate the number of individuals from incomplete commingled remains, and over how to distinguish the social and historical causes—epidemic, violence, or ritual—of mass deposits.

Frequently asked questions

What is the minimum number of individuals?

It is the smallest number of people that can account for the skeletal elements present, calculated by counting the most frequent repeated element and side, and it provides a baseline estimate for commingled remains.

Why would many people be buried together?

Mass burials can result from epidemics, battles or massacres, natural disasters, or deliberate collective tombs, and distinguishing among these requires evidence from the bones, their arrangement, and the archaeological context.
