Entheseal variation and locomotor behavior during growth.

Entheses are acknowledged as skeletal markers capable of revealing several biological and behavioral aspects of past individuals and populations. However, entheseal changes (ECs) of juvenile individuals have not yet been studied with a systematic approach. This contribution aims at investigating the morphological changes occurring at the femoral insertion of the gluteus maximus and tibial origin of the soleus muscles to highlight a potential link between the morphological features of those entheses and skeletal maturity in relation to sex, age, and locomotor developmental patterns. The sample consisted of 119 skeletons (age-at-death: 0-30 years) belonging to the Documented Human Skeletal Collection of the Certosa Cemetery (Bologna, Italy). The entheseal variation during the last stages of skeletal maturation in young adults was assessed using existing recording standards. A recording protocol for each enthesis was developed for immature individuals to subdivide the morphological variability into discrete categories. Univariate, bivariate, and multivariate statistical analyses were performed to investigate the variation of entheseal morphologies and measurements in relation to bone metrics, degree of epiphyseal closure, sex, age, and locomotor developmental patterns. A statistically significant relationship was observed between ECs morphological patterns and age for both entheses, while sexual differences were negligible. A relationship between ECs morphological pattern and locomotor milestones emerged only for the gluteus maximus. Even though further testing is needed on other documented skeletal collections, our protocol could be usefully applied in forensic and archaeological fields and serving as important reference for evolutionary investigations.

On the traces of lost identities: chronological, anthropological and taphonomic analyses of the Late Neolithic/Early Eneolithic fragmented and commingled human remains from the Farneto rock shelter (Bologna, northern Italy).

The present study examines the prehistoric human skeletal remains retrieved starting from the 1920s in the deposit of the Farneto rock shelter, situated in the area of the 'Parco dei Gessi Bolognesi e Calanchi dell'Abbadessa' (San Lazzaro di Savena, Bologna, northern Italy). An exact dating and a reliable interpretation of the assemblage had not been reached so far because of the lack of contextual data useful for dating purposes, the inaccurate recovery procedures of the remains and their state of preservation. In fact, the skeletal remains from the Farneto rock shelter are highly fragmented and commingled, whereas reliable information about their original position and their recovery procedures are not available. Despite these difficulties, radiocarbon analyses allowed the precise dating of the remains to a final phase of the Neolithic and an early phase of the Eneolithic period in Emilia Romagna (northern Italy). The study of the assemblage enabled to clarify the use of the context for funerary purposes. Moreover, the anthropological and taphonomic analyses of the skeletal remains shed light on the biological profile of the individuals and on some events that occurred after their death. In particular, the analysis of perimortem lesions highlighted the existence of intentional interventions related to corpse treatment, referable to dismembering/disarticulation and scarnification, i.e. cleaning of bones from soft tissues. Finally, the comparison with other Italian and European Neo/Eneolithic funerary contexts enabled a better understanding of these complex ritual practices.

Unveiling an odd fate after death: The isolated Eneolithic cranium discovered in the Marcel Loubens Cave (Bologna, Northern Italy).

An isolated human cranium, dated to the early Eneolithic period, was discovered in 2015 at the top of a vertical shaft in the natural Marcel Loubens gypsum Cave (Bologna area, northern Italy). No other anthropological or archaeological remains were found inside the cave. In other caves of the same area anthropic and funerary use are attested from prehistory to more recent periods. We focused on investigating the circumstances surrounding the death of this individual, since the cranium shows signs of some lesions that appear to be the results of a perimortem manipulation probably carried out to remove soft tissues. Anthropological analyses revealed that the cranium belonged to a young woman. We analysed the taphonomic features and geological context to understand how and why the cranium ended up (accidentally or intentionally) in the cave. The analyses of both the sediments accumulated inside the cranium and the incrustations and pigmentation covering its outer surface suggested that it fell into the cave, drawn by a flow of water and mud, likely from the edges of a doline. The accidental nature of the event is also seemingly confirmed by some post-mortem lesions on the cranium. The comparison with other Eneolithic archaeological sites in northern Italy made it possible to interpret the find as likely being from a funerary or ritual context, in which corpse dismemberment (in particular the displacement of crania) was practiced.
