| Résumé : | Sex estimation of burnt human remains is a tremendous challenge in bioanthropology because of fragmentation and alteration. Due to its peculiar location within the petrous part of the temporal bone, the bony labyrinth raises interest for improving sex estimation of burnt individuals. This study proposes to test, on burnt specimens, the reliability of predictive models, previously developed on unburnt bony labyrinths. Logistic regression equations were applied on CT-scans of six bony labyrinths of donated identified adult cadavers, before and after outdoor burning experiments. Mann-Whitney U tests were executed to compare unburnt and burnt measurements while a geometric morphometrics approach was used to examine shape and size differences induced by fire exposure. Although estimated sex of unburnt bony labyrinths was mostly consistent with known sex, a systematic misclassification of male burnt bony labyrinths was highlighted. After calcination, significant differences in centroid size were found within males, with a reduction in cochlear size and variations in the width and length of semicircular canals in burnt specimens. Designing sex estimation standards specifically for burnt bony labyrinth may therefore be more advisable. To better understand how the burning process could impact its morphology, further experiments on larger samples and in controlled environments are recommended. |
