Identification of Neolithic diet by the morphology of the starch grains of dental calculus found in the Dehesilla cave (Cadiz – South of the Iberian Peninsula)
Publication . Coutinho, António Pereira; Moreira, Margarida; Silva, Eduarda; García-Rivero, Daniel; Umbelino, Cláudia
The starch grains present in the dental calculus of four Neolithic individuals of the Dehesilla Cave (Cadiz, South of Spain) were extracted and observed with light microscopy. The variant of the extraction technique used proved to be very effective. A number of Poaceae-Triticeae taxa [wheat (Triticum sp., the main crop, including Triticum aestivum), barley (Hordeum sp.)], Fabaceae-Fabeae-Cicereae and Fagaceae (oaks = Quercus sp., which constitute new data for the area in question) were identified. Some pollen grains and fungal spores were also identified, which helped to provide information on the ecological framework of the crops associated with the archaeological site.
The unidentified skeletal collection of Capuchos cemetery (Santarém) housed at the University of Coimbra
Publication . José, Andreia; Tomé, Laura; Coelho, Catarina; Cunha, Eugénia; Umbelino, Cláudia; Ferreira, Maria Teresa
The aim of this article is to present to the scientific and academic community a new osteological collection housed at the Department of Life Sciences from the University of Coimbra (Portugal), the Unidentified
Skeletal Collection of the Capuchos Cemetery.
The skeletons were collected from the same cemetery as those of the 21st Century Identified Skeletal Collection, however their identity is unknown. The collection is comprised of 73 individuals, of which 68 are adults of both sexes (34 females, 33 males, and one individual of unknown sex) and five are non-adult
individuals. It is estimated that the majority of adult individuals have a European ancestry.
Changes in dental wear magnitude in the last ∼8000 years in southwestern Iberia
Publication . Godinho, Ricardo Miguel; Umbelino, Cláudia; Garcia, Susana; Gonçalves, Célia
Objective: This study examines changes in dental wear magnitude in the past -8000 years, i.e., since Mesolithic until the 19th century, in southwestern Iberia. Thus, it encompasses the transition from hunting-gathering to agro-pastoralism, and then to the industrialization of food production and pre-processing. Design: Dental wear magnitude was scored in a total of 191 individuals and 1557 teeth from Mesolithic (individuals=56; teeth=643), Neolithic (individuals=35; teeth=169), Chalcolithic (individuals =35; teeth=221), Modern Age (individuals=17; teeth=209), and Late Modern Age (individuals=48; teeth=315) samples originating in southwestern Iberia (i.e., present central and southern Portugal) and according to the 8 levels ordinal scale of Smith (1984). Results: Results show a general trend for decreased wear magnitude in these two major transitions and during this timespan (although the hunting-gathering - agro-pastoralism transition had larger impact). The only meaningful differences in wear rate were found between the Late Modern Age and all remaining samples. Conclusion: Dental wear generally decreased during this timespan (although wear magnitude was less impacted by the industrialization of food production and pre-processing). Our results are consistent with studies documenting skull morphological gracilization associated with reduced masticatory demands due to the adoption of softer diets.
Mesolithic and chalcolithic mandibular morphology: using geometric morphometrics to reconstruct incomplete specimens and analyse morphology
Publication . Godinho, Ricardo Miguel; Umbelino, Cláudia; Gonçalves, Célia
Human skeletal remains are routinely used to examine cultural and biological aspects of past populations. Yet, archaeological specimens are frequently fragmented/incomplete and so excluded from analyses. This leads to decreased sample sizes and to potentially biased results. Digital methods are now frequently used to restore/estimate the original morphology of fragmented/incomplete specimens. Such methods include 3D digitisation and Geometric Morphometrics (GM). The latter is also a solidly established method now to examine morphology. In this study, we use GM-based methods to estimate the original morphology of incomplete Mesolithic and Chalcolithic mandibles originating from present Portugal and perform ensuing morphological analyses. Because mandibular morphology is known to relate to population history and diet, we hypothesised the two samples would differ. Thirty-seven specimens (12 complete and 25 incomplete) were CT-scanned and landmarked. Originally complete specimens were used as reference to estimate the location of absent anatomical landmarks in incomplete specimens. As predicted, our results show shape differences between the two samples which are likely due to the compounded effect of contrasting population histories and diets.
Mandibular morphology and the Mesolithic–Neolithic transition in Westernmost Iberia
Publication . Godinho, Ricardo Miguel; Umbelino, Cláudia; Valera, António Carlos; Carvalho, António; Bicho, Nuno; Cascalheira, João; Gonçalves, Célia; Smith, Patricia
Neolithic farming and animal husbandry were first developed in the Near East similar to 10,000 BCE and expanded westwards, reaching westernmost Iberia no later than 5500 BCE. It resulted in major social, cultural, economic and dietary changes. Yet, the impact of this change on human mandibular morphology in Iberia is yet to be assessed, which is regrettable because mandible form is impacted by population history and diet. In this study we used Mesolithic to Chalcolithic Iberian samples to examine the impact of this transition on mandibular morphology. We also compared these samples with a Southern Levantine Chalcolithic population to assess their relationship. Lastly, we assessed dental wear to determine if the morphological differences identified were related to the material properties of the diet. We found differences between samples in mandibular shape but not size, which we attribute to contrasting population histories between Mesolithic and later populations. Some differences in the severity of dental wear were also found between Mesolithic and later Iberian samples, and smaller between the Mesolithic Iberians and southern Levantines. Little relationship was found between wear magnitude and mandibular shape. Altogether, our results show that the Mesolithic-Neolithic Iberian transition resulted in a meaningful change in mandibular morphology, which was likely driven more by population history than by dietary change.
