Abstract: The aim of this study was assessing the prevalence of os trigonum, talo-calcaneal facets, and squatting facet variations among pre-Hispanic individuals (around 940 ± 30 bp) placed in the collective burial cave of Punta Azul (El Hierro, Canary Islands), and to assess whether prevalence differed among sexes. A total of 149 tali (70 right and 79 left) belonging to adult individuals were found in a comingled context. Sex determination was achieved as follows: genetic sexing of a subsample of 35 tali was assessed using paleogenomic procedures. Anthropometric measurements of the genetically sexed bones were used to calculate an accurate discriminant function that was later applied to the remaining 114 tali. We observed marked differences in the os trigonum pattern among male and female tali, whereas no relevant differences were observed regarding the other two traits. A very high prevalence of squatting facets was observed in both sexes, higher than the reported frequencies for other population groups. The summarized conclusions in this study are the following: (a) the high prevalence of the squatting facets observed in both males and females could indicate the performance of a similar activity that requires a squatting position, such as shellfishing. (b) We observed a predominance of the type C talo-calcaneal facet configuration among the population that indicates a maximal mobility of the talar joint, well adapted to displacement and/or activities such as goat herding in the steep landscape of El Hierro. (c) The statistically different os trigonum pattern among sexes may suggest a greater activity associated to jumping and climbing among males, possibly related to goat herding in the steep landscape of the island of El Hierro.
