The southeast edge of the Loess Plateau (SELP) is a crucial area for studying subsistence strategies and social complexity in prehistoric China. Currently, no systematic isotopic study has been conducted to reveal shifts in subsistence strategies and their link to the trajectory of social complexity. This paper compiles previously published isotopic data from human and fauna bones at 24 sites dating from 8000 to 5000 BP, aiming to uncover diachronic changes in subsistence strategies and their relationship with social complexity. The results indicate a gradual increase in millet consumption by humans and an increasing utilization of millet-based byproducts as feed for domestic animals (pigs and dogs) over time. The isotopic data of humans and animals demonstrate the establishment of millet agriculture during the Early Yangshao period (7000–6000 BP). Millet agriculture creates a crucial material foundation for population growth and cultural prosperity. Two modes of millet cultivation, intensive and extensive, are proposed to explain the continuous development of millet agriculture since the Early Yangshao period. Finally, significant dietary heterogeneity among the human population during the Late Yangshao period strongly suggests the emergence of social differentiation and complexity, supported by other archaeological evidence such as settlement hierarchies and the presence of exquisite objects in burials.

Girnavaz Mound (Höyük), located in modern Türkiye, was studied between 1982 and 1991. The mound, inhabited from the Late Uruk Period to the Neo-Assyrian Period, was later abandoned and repurposed as a cemetery during the Late Roman–Early Islamic Period. Anthropological studies on skeletons from this cemetery analyzed 148 individuals from this period, revealing notable trauma in five individuals. This study examines the skeletal remains of four individuals with perimortem sharp force trauma and one individual with an in situ arrowhead injury. Macroscopic and CT analyses indicated that both perimortem and antemortem trauma were intentional. The skull and body bones of four individuals displayed incision trauma likely inflicted by sword-like cutting weapons, suggesting murder and decapitation, possibly as a form of execution. One individual had an arrowhead lodged in the tibia, indicating the person lived for some time with the injury and was buried with the arrowhead. This study aims to infer the period's political conflicts and cultural structures based on the trauma evidence. The findings suggest that the observed trauma may be linked to massacres and murders resulting from regional conflicts. This study offers exemplary insights into the mechanics and analysis of sharp force and perimortem trauma. Additionally, it sheds light on the social and historical context of the period.

The Later Iron Age in Britain was a transformative period: material culture, settlement patterns, technology, trade networks, and the structures of power changed, ultimately leading to the Roman invasion. This paper examines the significance of investigating animal economies in this period within the broader context of socio-economic developments. It reviews the available evidence regarding animal economies in this period, integrates new osteometric analyses, and discusses diachronic changes using the Roman evidence on a comparative basis. The investigation shows a broad pattern of continuity of practice, with relatively uniform livestock types and management strategies until the very end of the Iron Age. This suggests that the trajectory of local farming practices was largely independent from Mediterranean developments. This study contributes to a deeper understanding of Iron Age societies and their response to external influences, while also informing future research directions in archaeology.

Ocher has been observed as a feature of burial traditions around the world, throughout history and prehistory. In Southeast Asia ocher first appears in Hòabìnhian burials; however, it is used discriminately, varying within and between sites. Understanding the selection process for individuals with pigmented burials has been difficult due to their limited number. The site of Khok Phanom Di, Thailand, dating from ~4000 to 3500 BP, reflects the variation of pigment use seen in earlier sites, with 82% of burials found to have ocher. The cemetery's uninterrupted use for ~500 years, the high number and standard of preservation of human remains, and nearly four decades of bioarcheological research have facilitated a detailed study of the use of pigment in relation to bioarcheological factors. This work examines the relationship between the presence or absence of ocher within a burial and chronology, age, sex, mobility, funerary behavior, and spatial organization to understand whether there was a relationship between selective use of ocher and these attributes. The results found a relationship between ocher use and burial chronology, grave type, grave goods, and age. Multivariate analysis demonstrates that age interacts with the other predictors of ocher. Burials without ocher are almost exclusively those of perinates, these were commonly small, shallow “scoop” burials without grave goods. The presence of ocher in ~38% of perinate burials illustrates the complexity of selective pigment use and demonstrates the need for further research.

This study aimed to reduce subjectivity bias in scoring dental macrowear quantity and direction using the Brabant index, which previously relied solely on written descriptions. To achieve this, we present a new, optimized visual guide incorporating buccal and lingual scores. The optimization process involved conceptualizing and illustrating a visual guide using Holocene southern African hunter-gatherer and herder teeth, featuring both buccal and lingual scores for multicuspid teeth. The guide was hand-drawn using a stippling technique and digitized to depict surface details for each wear stage and tooth type. We conducted intra- and inter-observer assessments to evaluate the optimized method using both the original and optimized Brabant indices. Statistical analysis was performed in R using Cohen's kappa for direction and Cohen's weighted kappa for quantity. Intra-observer results for the original method yielded kappa values of 0.84 for direction and 0.94 for quantity, while the optimized version both resulted in improved values of 0.99. Inter-observer results revealed some differences between an inexperienced and an experienced observer. The inexperienced observer achieved kappa scores of 0.20 for direction and 0.86 for quantity with the original method, and 0.17 and 0.80, respectively, with the optimized version. The experienced observer's results using the original index were 0.66 for direction and 0.89 for quantity, and 0.75 and 0.96, respectively, with the optimized version. These findings demonstrate that the optimized method enhances data reliability for experienced observers, highlighting the value of a published visual guide and multicuspid scoring adjustments. However, reduced or unappreciable changes in accuracies for the inexperienced observer illustrate the need for dental expertise when scoring for dental wear, even with a modified method.

Increasing urbanization seen during the medieval period (7th to 16th centuries) is associated with adverse living conditions that may have negatively impacted childhood growth via the influence of infectious diseases and nutritional deficiencies due to increasing population density and periodic food shortages. This study aims to compare the growth of non-adults (less than 12 years of age) from urban, proto-urban, and rural environments from medieval England to determine whether settlement type influenced child health, and by proxy overall population health, during this period. Tibial and femoral maximum diaphyseal lengths and dental age of non-adults (0–12 years) from urban St. Gregory's Priory (n = 60), urban York Barbican (n = 16), proto-urban Black Gate (n = 38), and rural Raunds (n = 30) were examined using z-scores. The results reveal that non-adults < 2 years from St. Gregory's Priory had the lowest growth values followed by Raunds, Black Gate, and York Barbican with the highest growth values. Further, non-adults 2–12 years from York Barbican had the lowest growth values followed by Raunds, Black Gate, and St. Gregory's Priory with the higher growth values. The femoral and tibial diaphyseal growth values are explored within the context of breastfeeding and weaning practices, stability of economies, and environmental conditions.

Harris lines (HLs) are radiographically visible transverse lines of thickened bone that develop from temporary growth cessation during early life. Often attributed to physiological stress during development, HLs are frequently observed in the long bones of adolescents and become less visible over time due to bone remodeling. In recent years, the validity of HL as a sign of stress has been called into question and the methods used in studying HL through X-ray analysis scrutinized. In this study, 80 individuals from the Middle Holocene Cis-Baikal region of Siberia, from the Early Neolithic (EN; 7560–6660 HPD cal. BP) and Late Neolithic (LN; 6060–4970 HPD cal. BP), were studied for the presence and severity of HL. Radiographic analysis employed both the traditional clinical anteroposterior (A–P) orientation and a potentially improved mediolateral (M–L) orientation. EN groups in the Cis-Baikal are known to have experienced higher levels than their LN counterparts; thus, if HL reflect stress experiences, we expected to see more HL in the EN population compared with the LN population. We also expected more visible HL in the M–L orientation due to the suggested improvement in capturing more lines compared with the A–P orientation. While the results support the use of M–L orientation during X-ray capture of HL, there was not a higher number of HL in the EN population as expected. Instead, no significant differences were found in HL severity between the EN and LN populations, and age-at-death resulted in a greater effect on HL counts regardless of mortuary site. The results from this study align not with known stress data from the Middle Holocene Cis-Baikal populations but rather with data pertaining to known growth patterns. We therefore advocate against the use of HL as a sign of physiological stress and instead suggest HL as a reflection of bone growth trajectory.

Classic period Maya populations were mobile, and both burial patterns and dietary analyses suggest that many movers were incorporated into local communities. This paper presents a multi-isotopic (Sr, O, S, C, and N) study of the diet and mobility of 18 Late (AD 550–800) and Terminal Classic (AD 800–900) individuals from the site of Pacbitun, Belize. Three distinct isotope systems identify where people lived at different stages of life, from the childhood origins of migrant and local Pacbitun populations to their final residences. The enamel strontium isotope ratios of the Court 3 individuals were higher than local ranges established by faunal and human bone values, suggesting elite migration, or even residential mobility within the polity. Sulfur isotope values reveal information about the local population, where all but one individual in the sample lived at the site for many years before they died. The exception was an isotopically nonlocal individual in a dedicatory deposit, as reported in other studies. Diet also informs on the receiving community and how migrants assimilated, as people with local and nonlocal isotope values ate isotopically similar foods. Individuals from elite site core contexts and those in Pacbitun's peripheral settlements both consumed C₄-enriched proteins, though there were more isotopically diverse protein sources in peripheral settlements during the Terminal Classic period. Sulfur, carbon, and nitrogen isotope data also reveal some differences in where food was acquired, including use of nonlocal fauna. Combining isotope systems that sample different body tissues also may blur the line between migrants and locals, terms that may describe the same person at different stages of life and show the need for a more nuanced discussion of ancient mobility.

This report describes a male skeleton recovered from the Samnite necropolis of Barrea (Abruzzo, 8th–5th century BCE), showing one malformed foot consistent with the diagnosis of unilateral congenital clubfoot associated with tarsal and tarsometatarsal coalitions in the same foot. This finding is particularly noteworthy because tarsal coalitions in congenital equinovarus foot have rarely been reported in medical literature, and to our knowledge, never in the paleopathological record. The recovery of this individual with impaired locomotion from a grave containing a complete array of weapons and armor sheds new light on the occupant's identity and social attitudes toward disabled people in Samnite society. In mortuary archaeology, the correlation between warrior burials and social identity in life of the dead in ancient times is a widely debated issue. Some scholars assert that the weapons in these graves suggest the existence of a warrior class; others propose that the military items of the burial assemblage indicate a high social status or significant power. This study suggests that in Samnite society, physical impairment did not prevent someone from being honored as a warrior or high-status community member.
