- Cortical bone loss in a sample of human skeletons from the Muge Shell middensPublication . Umbelino, Cláudia; Curate, Francisco; Perinha, Andreia; Ferreira, Teresa; Cunha, Eugenia; Bicho, NunoThe Muge shell middens of Cabeco da Arruda, Cabeco da Amoreira and Moita do Sebastiao (central Portugal) have been key sites of archaeological research for 150 years, possibly working as residential sites occupied by semi-sedentary communities during the final Mesolithic. The purposes of this article include the biocultural assessment of metacarpal cortical bone fragility and its associations with age at death, sex and osteoporotic fractures in the Portuguese Mesolithic, as well as a diachronic comparison of cortical bone health in Mesolithic (N = 34) and modern reference (N = 219) samples. Cortical bone at the Muge shell middens displays age and sex-specific trajectories of periosteal apposition and endosteal bone loss, most likely associated with hormonal and behavioural/cultural influences. Metacarpal endocortical bone loss seems to increase with age at death in females, with a simultaneous expansion of the diaphysis. The overall pattern of cortical bone health is similar to the pattern observed in a reference skeletal collection, but elderly women from Muge seem to lose less cortical bone than late twentieth century counterparts from Coimbra. Two older males exhibited vertebral compression fractures, but only one is possibly related with bone fragility.
- Resilience, replacement and acculturation in the Mesolithic/Neolithic transition: The case of Muge, central PortugalPublication . Bicho, Nuno; Cascalheira, João; Gonçalves, Célia; Umbelino, Cláudia; García-Rivero, Daniel; André, LinoEvidence for the first Neolithic population in central Portugal dates to as early as c. 7600 cal BP. These first farmers were exogenous groups arriving to the Atlantic coast from the Mediterranean Sea. For a few centuries there seems to have occurred an overlap in the region between the Mesolithic Muge huntergatherers and the regional early Neolithic populations. While the trajectory of these first farmers seems to be well established, the fate of the Mesolithic populations is unknown and in generally assumed as resulting in extinction. The recent results from research in the Muge Mesolithic shellmounds (Tagus valley) with the new recovery of various loci with Neolithic occupations including human burials, human DNA, and Strontium analyses seem to indicate evidence of cultural and genetic integration between the Mesolithic and Neolithic populations. This paper will focus on the Mesolithic-Neolithic transition in Portuguese Estremadura and examines the hypothesis that human resilience promoted the cultural and biological integration of the Mesolithic groups into the new exogenous Neolithic communities in central Portugal.
