Beyond the Binary? A Multi‐Method Approach to Sexing Children at the Viking Age Site of Ihre, Gotland

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT The assessment of sex is fundamental in osteoarcheological analysis, yet traditional morphological methods are less reliable for children due to the incomplete development of sexually dimorphic traits. This study applies a multi‐method approach—integrating morphological, metric, and genetic data—to assess sex and, through analysis of burial ...
