Bone decomposition in archaeological contexts is differential and dependent on geological and taphonomic variables. The present work analyses evidences of skeletal diagenesis in 25 inhumations (3rd-4th to 5th-7th centuries) from the Via XVII necropolis of Bracara Augusta (Braga, Portugal).Bracara Augusta is located in the Minho region, Northwest Portugal. Minho’s granitic soils are characterized by high acidity. Precipitation is high in cold seasons and markedly reduced in the summer. The influence of these factors on bone preservation of Via XVII inhumations was analyzed through the comparison between graves with different structural traits (box presence, box material, sediment presence, chronology, coffin/stretcher presence or material, and cover presence or type), using the chi squared test. None of the comparisons showed significant differences in skeletal preservation frequencies. Yet, the comparison between graves that structurally limit skeletal contact with sediment (sealed/undisturbed boxes) or water flow (gable roof boxes) (100%) and the remaining graves (43.8%) presented significantly different frequencies (χ2 = 7.910; p = 0.005).The taphonomic conditions of Via XVII inhumations are inadequate for bone preservation. In graves preserving osteological material, the presence of a box structure is essential, yet only of determining influence if kept sealed or covered with a gable roof. The continued study of taphonomic factors influencing bone diagenesis will allow the preparation of archaeological excavations in Braga funerary contexts to account for the needed specialists and materials. Diagénese óssea em inumações da Via XVII (Bracara Augusta): Identificação de fatores tafonómicos e ambientais na preservação esquelética diferencialA decomposição dos ossos em contexto arqueológico é diferencial, dependente de variáveis geológicas e tafonómicas. O presente trabalho analisa evidências relativas à diagénese esquelética em 25 inumações (séculos III-IV a V-VII) da necrópole da Via XVII de Bracara Augusta (Braga).Bracara Augusta localiza-se no Minho, região no noroeste de Portugal Continental de solos graníticos caracterizados por elevada acidez. A precipitação é elevada nas estações frias, reduzindo-se marcadamente em períodos quentes. A influência destes fatores na preservação óssea das inumações escavadas na Via XVII foi pesquisada pela comparação entre sepulturas de diferentes características estruturais (presença de caixa, material da caixa, contacto com sedimento, cronologia, presença de caixão/padiola, tipo e presença de cobertura), recorrendo ao chi quadrado. Nenhuma das comparações revelou diferenças significativas nas frequências de preservação esquelética. No entanto, a comparação entre sepulturas de estrutura limitadora do contacto com sedimento (caixas seladas/não perturbadas) ou do fluxo de água (caixa com cobertura de duas águas) (100%) com as restantes sepulturas (43,8%) revelou frequências significativamente diferentes (χ2 = 7,910; p = 0,005).As condições tafonómicas das inumações da Via XVII são inadequadas para a preservação óssea. Nos casos em que se preservam evidências osteológicas, a presença de estrutura em caixa é fundamental, mas só tem influência determinante se se mantiver selada ou tiver cobertura de duas águas. A continuação do estudo dos fatores tafonómicos que mediam a diagénese óssea permitirá que a preparação das escavações arqueológicas de contexto funerário em Braga determine os especialistas e instrumentos adequados ao projeto.

Biological profile estimation is an important task of biological and forensic anthropologists. This includes sex, age, ancestry, and body morphology. In bioarchaeology, the biological profile is useful to analyze paleodemography, secular trends, paleopathology, and genetic processes, for example. Foot dimensions, footprints, and shoeprints can vary according to stature, age, sex, and body weight. The objective is to estimate these parameters in possible laterarii (brickworkers) from five footprints and seven shoeprints found in Roman bricks from Bracara Augusta. Estimation methods were applied to footprint and shoeprint measurements concerning foot length, foot breath, heel breadth, and length from heel to each finger. Three non-adult individuals were aged 1 to 4/5 years and were between 79.7 and 112.5 cm (±7.7 cm) tall. Five adults were likely female individuals, with statures between 144.2 and 159.9 cm. Methods were selected from samples preferably biologically similar to Portuguese people. This pioneer analysis provides biological insight on the Bracara Augusta laterarii and the population inhabiting Northwestern Iberia during Roman times. As a result of taphonomic constraints (cremation, soil acidity, and humidity), coeval osteological materials are hardly recovered, which further increases the relevance of this approach. Future research on methods based on Portuguese foot dimensions is essential.

Dental morphology is a useful resource in archaeology, anthropology and paleontology, due to its genetic determination. Teeth are a material of high durability and stability. This work aims to study the dental morphology and test the Portuguese and European biological affinities of an undocumented mandibular sample, through comparison with global and Iberian samples. The dental traits in 163 mandibles (kept at the Museum of Natural History of the University of Oporto, Portugal) were scored using a standardized methodology (ASUDAS: Arizona State University Dental Anthropology System) and compared to other world-wide and Iberian samples through Principal Components (PCA) and Mean Measure of Divergence analyses. The undertaken quantitative and statistical tests demonstrated the unknown sample to be closer to the Coimbra Portuguese sample in all three comparisons. This suggests this undocumented mandibular sample is possibly of Portuguese 19(th)/20(th) century origin.

The utility of nonmetric dental traits in population phenetic studies is well documented. However, consistency in scoring trait expression is a concern due to the subjectivity in scoring quasicontinuous variables with graded scales. The aims of this study are to 1) analyze intraobserver results from an independent scorer and 2) interpret the least precise results. Six hundred individuals (300 of each sex) were scored for 48 dental nonmetric traits using ASUDAS, in one preliminary (100 individuals) and two full observations. Intraobserver precision between scoring sessions yielded adequate results (85% to 100%), with two notable exceptions (UI2 tuberculum dentale and LC distal accessory ridge) and three somewhat problematic cases (UM2 hypocone, UM1 Carabelli's trait, and LM1 anterior fovea). Kendall's τ-b rank correlation coefficients are usually moderate to strong (> 0.3). The results are similar to previously published studies of observer error. Error rates are likely caused by inexperience in observable surface selection and trait/grade definition. ASUDAS requires restraint from scoring teeth that are too worn or modified by caries or chipping. A careful study of trait and grade definitions is strongly encouraged. The key element in achieving high precision rates is experience. Intraobserver (and, if needed, interobserver) error should always be calculated. Overall, ASUDAS is a reliable and useful method, especially if the author's recommendations are followed.

A reference sample of dental and oral nonmetric traits should represent its biological population from which it stems. The presence of individuals born at different times, different regions, and separate countries in the Coimbra-identified cranial collections provides the test of whether this sample reflects the biological continuity of this Portuguese sample among the late modern (early industrialization, nineteenth century) to early contemporary (early demographic transition, first half of the twentieth century) population of this region of central Portugal. The Coimbra collections were scored for 61 traits using methodology by Hauser and De Stefano (1989), Turner et al. (1991), Scott and Turner (1997), Irish (1998), and Marado and Silva (2016). The 600 individuals in the sample were divided by generation, region, and nationality. Their phenetic diversity was tested with principal component analysis and with the mean measure of divergence statistic. The proximity between the subsamples was generalized, and it mimicked previous genetic marker results. Some small subsamples hindered conclusions; nevertheless, this Coimbra sample is considered a reliable dental reference sample for the Portuguese late modern/early contemporary population.
