Part of multiple Roman fortifications along the Limes dating from 40 A.D. onwards, the cemetery was likely used as a burial ground for inhabitants of the Valkenburg fort or nearby vicus, a civilian settlement. The cemetery comprised at least 250 cremated individuals as well as 47 inhumations, which is a striking find that contradicts the common Roman practice of cremation. Due to these inhumated skeletal remains, the site provides an unique opportunity to employ osteoarchaeological analysis to reconstruct the lives of individuals that lived in the Roman Frontier region. This thesis utilizes cross-sectional geometry and bilateral asymmetry analysis to infer activity patterns among individuals at the Valkenburg-Marktveld cemetery, as current research on the differences in bone geometry between different demographic groups within Roman communities in the Lower Rhine area is limited. The study further investigates the factors and potential activity patterns that might influence those variations, such as biological age and sex. To do so, it builds on the initial osteoarchaeological study conducted by Lonnée and Maat (1998), who reported the estimated sex and age-at-death of each individual. Following this, each relevant bone in the upper and lower limbs was measured on various points to generate the indices for each point of measurement, as well as calculate the percentage directional asymmetry (DA%) and absolute asymmetry (AA%). The resulting values were then compared statistically between the biological sexes and age-at-death categories. While statistical significance is limited, the interpretation of data highlights the potential of these analyses in inferring activity patterns. Results from the analysis indicate that males tend to display more robust and symmetric upper and lower limbs than females, which are likely attributable to biological factors or a wider range of activities in males. Age-at-death categories exhibited inconsistencies with patterns described in other study, which is possibly due to natural variation or the limited preservation and availability of the skeletal material. Despite the limited number of individuals that could be examined, this thesis contributes valuable insights into the application of cross-sectional geometry and bilateral asymmetry analysis in osteoarchaeological studies, complementing historical data and broadening our understanding of activities in Roman frontier regions.Show less

These could in turn be linked to biological sex, environment and historical period and offer new insights in the lifestyle, in particular physical activity, of historical populations from the Netherlands. The results of this thesis could in turn also contribute to a better understanding of femoroacetabular impingement in the modern age. The trend that the femoral heads of the males in this sample are significantly less spherical than in females may be related to a sex-based labour division. Males would have done the bulk of the heavy work which put more strain on their lower limbs. The most important takeaway from this thesis is that femoroacetabular impingement, in particular cam-type, is not a new disorder. It is present in a wide range of populations from different environments and historical periods. The activity levels and physical load on the proximal femur of modern professional athletes may be comparable to ancient populations who were involved in physically demanding professions daily. The environment and diet might play a larger role in all of this than anticipated.Show less

Schöningen 13II-1 (site 13, channel II, level 1) was the first and oldest sedimentary cycle of Schöningen 13II from the bottom, dating to MIS 9 interglacial at around 300 ka. The climate at Schöningen 13II-1 was reconstructed to be the warmest compared to the climate of other layers at Schöningen 13II. The landscape of Schöningen 13II-1 was featured with forested and regularly flooded marsh. The preservation of faunal assemblages as well as lithics provides a good opportunity to conduct taphonomic and spatial analysis to reconstruct the depositional and post-depositional processes of Schöningen 13II-1. The taphonomic analysis of large mammal remains has revealed that both hominins and carnivores were involved in the accumulation and modification of faunal deposits which were evidenced by the percussion marks and carnivore gnawing marks, fragmentation pattern, as well as the skeletal presentations. The coexistence of hominins and carnivores was also documented in fragments with percussion and carnivore gnawing marks on the surface. However, the absence of overlap between these marks made it challenging to determine which group initially accessed the carcasses. The total absence of hominin cut marks and less frequent carnivore-induced modifications might be the results of abiotic agents that engaged in the taphonomic processes of altering bone surfaces, which were consistent with the varying degrees of weathering and abrasion of bones. For the results of spatial analysis, the fauna remains were distributed in a clustered pattern, which could be the results of where the fauna died naturally, such as rhinoceros bones. Additionally, the influence of hominin activities and carnivores carrying carcasses away first and consuming them cannot be ruled out. The patterns of orientation and vertical distribution indicate that different parts of Schöningen 13II-1 might have been affected by post-depositional processes to various extents which could be the bioturbation, and abiotic agents such as water movement from flooding and glacial erosion. Due to the post-depositional processes, it was hard to differentiate each accumulation event by hominins and other predators that happened at Schöningen 13II-1. However, regarding vertical distribution, the accumulations of faunal remains and lithics were mainly concentrated in the upper sublayers of Schöningen 13II-1. This could be interpreted as the outcome of spatial palimpsest formed over an unknown time scale. Within this context, various independent events involving biotic or abiotic agents happened at Schöningen 13II-1, depositing atop one another in a sequence that might have been disturbed by post-depositional processes. Despite the impact of post-depositional factors that might obscure the original spatial and taphonomic information of the accumulations, it is plausible to conclude that hominins were already well adapted to the interglacial environments by consciously taking advantage of forested lakeland with rich resources and less competition with other predators, to exploit botanic and faunal resources during the Middle Pleistocene in Central Europe.Show less

Conducted in Arnhem and Middenbeemster, this study reveals notable variations in the age at which children achieve important developmental milestones. Children in Arnhem tended to reach these stages at slightly older ages than their peers in Middenbeemster, underscoring the influence of regional factors on childhood development. Femoral angle measurements, specifically the bicondylar angle (BCA) and neck-shaft angle (NSA) were compared between the two regions, revealing distinct trends. Children in Arnhem exhibited higher average BCA and NSA values, potentially influenced by variations in lifestyle, parenting practices, and regional customs. Moreover, differences in NSA values may indicate disparities in biomechanical loading, emphasizing the multifaceted nature of childhood development. Comparisons were made with research on post-medieval England by Swan et al. (2020), demonstrating both similarities and differences in developmental patterns, reinforcing the significance of population-specific variations in bone development. The study also explores the onset of walking in low-status and high-status children, highlighting the potential influence of the specific region or environment on which they grow up when they start walking. These findings underscore the importance of considering multiple factors and measurements when studying child development, acknowledging that not all anatomical features are equally relevant to the specific aspects of development being investigated. The study encourages further research to explore the underlying factors contributing to differences in child development between Arnhem and Middenbeemster and to delve deeper into the biomechanical and physiological aspects influencing femoral angles. In conclusion, this research enriches our understanding of how cultural, environmental, and regional factors shape child development, specifically in the context of femoral angle measurements in Dutch post-medieval children. The study highlights the need for a comprehensive approach to osteological non-adult research, considering the intricate web of influences that contribute to developmental patterns.Show less

These sources can be subjective and nationalistic however, resulting in a negative preconception of Ancient Nubian communities. This can also be seen in the field of osteoarchaeology, where fractures found on Nubian individuals often automatically are connected to acts of interpersonal violence. Other, more positive explanations such as the practice of sports within the communities, are not often reviewed. This study looked at the remains of the human remains collection of Abu Fatima to try and find a connection between fractures in the hands and wrists and the practice of contact sports instead of interpersonal violence. For this research, 39 individuals were studied to determine the amount and types of injuries found in the remains of their hands and wrist. The collection was also compared to two Nubian collections connected to interpersonal violence (the Kerma collection and the collection from the NDRS project) and two modern individuals known to participate in Boxing from the Hammam Todd collection. As osteological studies connected to violence and sports often focus on injuries in the craniofacial area, if any injuries were found on the individuals their cranium was also studies in order to gather more information regarding the injury patterns. Different types of fractures and other signs of traumas were found on the human remains of Abu Fatima. Five parry fractures were found, all in the left arm. 17 metacarpal fractures were documented. There were no fractures in the carpal bones, but there were secondary signs of trauma such as osteoarthritis and ankylosis in hands that also showed other signs of trauma such as fractures. Two fractures were found on proximal phalanges. Three other phalanges showed signs of secondary trauma as a result of a fracture in an other bone in the hand. Lastly, four individuals showed signs of fractures on their cranium. The results showed that 10 of the 39 individuals showed signs of trauma in their hands or lower arms. These results implicate that the individuals from Abu Fatima suffered less traumatic hand injuries than the individuals from the rural sites of the NDRS project, but more injuries than the individuals from the capital city of Kerma. The injuries found in the human remains of the Abu Fatima collection do not support the hypothesis of a practice of contact sports within the community of Abu Fatima with certainty. The injury patterns found in the individuals from the Abu Fatima collection show similarities with both modern boxing individuals as the individuals from Kerma and NDRS, which are connected to interpersonal violence. A new theory has been introduced connecting the fractures in this research to the practice of Ancient stick fighting, a sport very popular in Ancient Nubia which has not yet been studied on possible injury patterns.Show less
