- The anatomical bases of the 3D digital facial approximation of the Zlatý kůň 1 woman (ca. 43,000 BP)Publication . Moraes, Cicero; Galassi, Francesco Maria; Sineo, Luca; Šindelář, Jiří; Varotto, Elena; Mietlińska-Sauter, Joanna; Antunes-Ferreira, Nathalie; Habicht, Michael E.; Beaini, ThiagoIn 1950 on Mount Zlatý kůň (‘Golden Horse’) in modern-day Czech Republic a system of caves was discovered. During many years of research in this area, human and animal osteological remains have been excavated, among which the most interesting ones were nine fragments of a female skull, now dated to ca. 43,000 yrs BP which are one of the earliest known anatomically modern humans in Eurasia. The aim of this research was to use purely digital techniques to: (1) to reconstruct the skull based on the 3D data of preserved fragments, (2) to approximate the probable appearance of the female it belonged to, and (3) to analyze the calculated shape of the reconstructed mandible and volume of the neurocranium in the context of similarities and differences with other representatives of the genus Homo. Computer techniques used in this research constitute a new, original approach to the problem of 3D analyses and may be useful primarily in bioarchaeological sciences, where metric analyses of the most valuable bone artifacts are often severely limited due to the incompleteness of the material available for research. The digital techniques presented here may also contribute significantly to the field of surgery, with the possibility of being adapted for applications in cranial prosthetics and post-traumatic reconstructive surgery.
- Chronic disease and disability in an 18th-Century Portuguese nun : an integrative multisource approachPublication . Antunes-Ferreira, NathalieThis study presents an integrative approach to chronic disease and disability in a Portuguese nun who died in 1779. The aim is to interpret her condition by combining osteopathological and burial context evidence with written sources. It offers a concise example of how bringing these sources together can enhance pathological interpretation and support the reconstruction of soft tissue disease, disability, and the lived experience of disease in past populations. This older woman was exhumed from the Convent of Jesus in Setúbal, Portugal. Her atypical burial position, also noted in the convent chronicles, indicates the remains likely belong to Michaela Archangela do Ceo. Osteopathological analysis revealed several changes, including atheromas, while the burial showed a crouched position, presumably related to stroke sequelae. The chronicles describe lifelong frailty and disease, followed in later life by a stroke with right-sided hemiplegia, pressure ulcers, and myiasis. Apart from the atheromas, which may be associated with the stroke, the skeletal changes show no correspondence with the signs reported in the account. The chronicles further document the attentive care she received, reflecting communal support within the convent, and the religious meaning of suffering. In conclusion, this case demonstrates the value of integrating multiple sources to interpret pathological conditions and the lived experience of disease, while emphasizing the relevance of soft tissue disease that leaves no skeletal trace. It also illustrates the careful application of retrospective diagnosis as an interpretive tool for historical documentation. Altogether, it highlights key methodological considerations for interpreting disease in osteoarchaeological contexts.
- DISH in an individual from the Portuguese Navy (18th-19th centuries)Publication . Antunes-Ferreira, Nathalie; Marques, Carina; Prates, Carlos; Alves-Cardoso, FranciscaIn 2005 the crypt of Espírito Santo Chapel (Loures, Portugal) was excavated. Forty-nine primary inhumations, comprising 37 adults (27 females; 10 males) and 12 non-adults were identified. Inhumations took place between 1561 and 1834. An adult male (> 35 years old) (Burial 1-Crypt 3) was individualized as belonging to the Portuguese Navy, based on the recovery of an uniform button associated with the burial. This individual exhibited exuberant bone lesions, affecting the vertebral region, sacroiliac joint, and extraspinal entheses. Bone changes were recorded macroscopically and complemented with radiological exam. The bone alterations are compatible with a diagnosis of diffuse idiopathic skeletal hyperostosis (DISH), according to Rogers and Waldron criteria.
- Exploring chemical traces of sharp force trauma in burned bone through SEM-EDS : a pilot studyPublication . Cunha, Ana Filipa; Quintas, Alexandre; Matos, António Pedro Alves de; Antunes-Ferreira, NathalieSharp force trauma (SFT) is a leading cause of homicide-related deaths, frequently involving kitchen knives as weapons. Offenders may attempt to eliminate forensic evidence by burning a corpse, complicating medicolegal investigation. While scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDS) has successfully detected metallic traces from sharp objects in skin and fresh bone, its efficacy in burned bone is currently unexplored. This study aimed to evaluate the potential of SEM-EDS to detect metallic residues transferred from sharp tools to bone that was subsequently burned, thereby contributing to the development of an identification procedure in forensic investigation. Ten knife strikes were inflicted on fleshed porcine ribs, which were then burned in an electric muffle furnace at 700 °C for two hours. Sharp lesions were analyzed using SEM-EDS to identify transferred chemical elements. Traces of iron and chromium were detected in seven lesions, with silicon identified in two samples. These elements, absent from the control samples, provided robust evidence of transfer from the blade to the bone. The residues appeared as bright spots with either undefined shapes or well-defined particles, located along the lesion edges. This study is the first to confirm the identification of metallic traces from SFT in bone subsequently exposed to heat using SEM-EDS. Despite thermal exposure, residues persist and remain detectable. SEM-EDS analysis is thus a non-destructive, valuable technique for distinguishing heat-induced bone damage from SFT. Further research with a larger sample and a broader range of implements is needed to validate and extend these findings for forensic applications.
- Extracapsular fracture of the femur in an elderly male from Setúbal (Portugal)Publication . Antunes-Ferreira, Nathalie; Prates, Carlos; Curate, FranciscoHip fractures were certainly present in past communities, if not reasonably frequent. Often an outcome of osteoporosis and increased risk of falling among the elderly, these fractures affect predominantly older women but also aged men. In this case-study, an extracapsular fracture of the femur in an elderly man is described and contextualized.
- Extracapsular fracture of the femur in an elderly male from the Church of Nossa Senhora da Anunciada (Setúbal, Portugal)Publication . Antunes-Ferreira, Nathalie; Prates, Carlos; Curate, FranciscoIn modern populations, hip fractures in older people are associated with high morbidity and mortality. Their incidence is rising; notwithstanding, fractures of the proximal femur are still relatively uncommon in archeological contexts. This case study represents a well-healed hip fracture in an aged male skeleton from Church of Nossa Senhora da Anunciada (16th–19th centuries AD) in Setúbal (Portugal). The individual was also diagnosed with diffuse idiopathic skeletal hyperostosis. Fractures of the proximal femur are usually associated with bone loss but in this case other causes are proposed, including the anatomy of the proximal femur, and the potential combined effect of diffuse idiopathic skeletal hyperostosis, cardiovascular disease, diabetes mellitus and falls.
- Interpreting injury recidivism in a rural post-medieval male individual from Bucelas, PortugalPublication . Antunes-Ferreira, Nathalie; Prates, Carlos; Curate, FranciscoInjury recidivism studies assess the lived experience of individuals who endure multiple traumatic incidents, conveying a nuanced contextualization of individual suffering within a reticulate of social and cultural processes. During a recent archaeological excavation, a skeleton of a middle-aged male dating to the 17th–18th centuries AD was excavated in the churchyard of the Chapel of the Holy Spirit in Bucelas (Portugal). This individual exhibited a mixture of healed and healing fractures that prompted poor functional long-term outcomes and an increase in the risk of death. Macroscopic and medical imaging (computerized tomography) analyses revealed lesions in the right shoulder, right and left ribs, fifth right proximal phalanx and right distal femur. Fracture complications include myositis ossificans and chronic osteomyelitis. The results are interpreted in the broader sociocultural circumstances of Bucelas during the early modern period, in order to investigate the causes of this individual's accumulated trauma and the possibility of health-related care associated with it.
- King Ariarathes IV of Cappadocia’s impotence in the light of thyroid disease: a multidisciplinar palaeopathological analysisPublication . Galassi, Francesco M.; Pate, F. Donald; Antunes-Ferreira, Nathalie; Varotto, ElenaFor a long time historical research dismissed the account about King Ariarathes IV of Cappadocia's (reigned 220–163 BC) wife being unable to produce an offspring just as a defamatory explanation concocted by later writers to cover subtler political moves. Having palaeopathologically re-examined the biographical record of King Ariarathes IV in the light of a recently proposed diagnosis of thyroid goiter, by multidisciplinarily combining literary and artistic evidence with biomedical knowledge and rationale, this article proposes an endocrinologically originated sexual dysfunction in King Ariarathes IV and offers a new reading of the subsequent shaming of his spouse.
- Kinship analysis using rare nonmetric dental traits in a prehistoric cemetery from Northeastern BrazilPublication . Solari, Ana; Antunes-Ferreira, Nathalie; Pessis, Anne Marie; Martin, Gabriela; Scott, G. RichardThis study evaluates whether three prehistoric burials containing 12 individuals (three adults and nine subadults) could represent family relationships in a small cemetery from a Middle Holocene site in Northeastern Brazil. In the absence of collagen for aDNA analysis, the hypothesis of genetic kinship relationship was verified through the analysis of nonmetric dental traits. Two rare nonmetric dental traits were analyzed: barrel-shaped upper lateral incisors (grades 6 and 7 on UI2 shoveling scale) and premolar odontomes. The relative frequencies of these traits were high in the sample, and statistical interpretation of the data revealed that the co-occurrence of these rare traits is unlikely to happen at random. Thus, their presence in individuals from the burial site of Toca do Enoque suggest plausible intracemetery genetic kin relationships.
- Leprosy in individuals unearthed near the Ermida de Santo André and Leprosarium of Beja, PortugalPublication . Antunes-Ferreira, Nathalie; Santos, Ana Luísa; Matos, Vítor M. J."Documentary sources refer to leprosy patients in the Portuguese territory since the first century AD, and in the Middle Ages around 70 leprosaria were established. However, prior to 2003 this historical evidence had not been confirmed by archeological findings. The excavation performed in monitoring the rehabilitation done by the Polis program in the area of the Ermida de Santo André (hermitage of Saint Andrew) allowed the exhumation of seven human skeletons, and commingled bones from at least three individuals, in the vicinity of the Beja leprosarium. The objective of this study is to present the paleopathological lesions relevant to the discussion of the differential diagnosis of leprosy. Macroscopic observation of the bones and scrutiny of lesions according to the paleopathological literature allowed the identification of a probable case of leprosy in an adult male, showing rhinomaxillary changes and concentric remodeling of hand and foot bones, and four possible cases (two young adults and two adults, all probably males), with a set of lesions in facial bones and skeletal extremities. The poor preservation of the bones precluded further confirmation of this diagnosis. According to historical data, the leprosaria functioned between the 14th and 16th centuries AD. The exact chronology of these findings was not determined either during the excavation or by radiocarbon dating because the bones presented poor collagen levels. In Portugal as a whole there are few osteological evidences of leprosy, and thus this study adds new information about this chronic infectious disease."
