Musculoskeletal stress and adult age markers in the Krapina Hominid collection: the study of femora 213 Fe.1 and 214 Fe.2.

The purpose of this study was to examine morphological markers of activity and age on femora 213 Fe.1 and 214 Fe.2 of the Krapina hominid collection. This study is part of a large research on the Krapina collection aimed at studying morphological markers of activity (entheses, enthesopathies, articular modifications) and age, as well as dento-alveolar alterations and pathologies. For this purpose, we apply scoring methods that we have devised and standardized on modern Italian skeletal collections with known age, sex, activity during life, cause of death, etc.. This approach has been used to study other human skeletal series and it allows us to obtain homogeneous data that can be more easily compared and interpreted. On the basis of our recent investigations of Upper Palaeolithic skeletal remains of Taforalt (Morocco, 12000-11000), we also intend to re-examine the cutmarks on bones of the Krapina hominid collection to provide further knowledge about possible funerary practices of these Neandertalians. The study of markers of activity and age on femora 213 Fe.1 and 214 Fe.2 revealed strong robusticity and a postero-lateral position of the m. gluteus maximus enthesis, indicating morphological and size differences with respect to modern humans. The strong mechanical stress on the lateral parts of the proximal end of the femur seems to be confirmed by the partial dislocation of the hip joint suggested by the articular features observed on two coxal bones. Finally, we used our results to re-assess the attribution of age to the individuals represented by these two specimens.
