Three cases of brachydactyly type E from two commingled tombs at the Late Intermediate period - Late Horizon site of Marcajirca, Ancash, Peru.

Objective: Here we present the first known examples of brachydactyly from an Andean archaeological context by describing the affected bones, presenting a differential diagnosis, and discussing the cultural implications of there being shortened metapodials in multiple tombs.

Materials: 3232 well-preserved tubular bones representing an MNI of 250 human adults.

Methods: Each bone was visually inspected.
