The paper discusses the formation of an enamel defect in the crown of a cave bear (Ursus spelaeus sensu lato) left maxillary second molar (M²), based on macroscopic and microscopic analysis. The tooth belongs to a cranium recovered from the Cerovac caves in Croatia that exhibits a partially healed, depressed lesion in the left squama frontalis and a further lesion in the left maxilla associated with loss of the M¹. Microscopic inspection demonstrated an accentuated incremental line in both enamel and dentin of the left M². It is suggested that in the defect area the outer enamel had been posteruptively lost along the accentuated line in the enamel that constituted a zone of reduced mechanical resistance. Presence of enamel hypoplasia in both M² indicated that these developmental lesions reflect a systemic stress event during crown formation of the teeth. The underlying cause of this stress is assumed to have been a trauma to the skull that caused the lesion in the left squama frontalis. It is further suggested that a later trauma to the left maxilla had led to the loss of the left M¹ and the flaking-off of enamel along the accentuated incremental line in the left M². The defect in the left M² is thus diagnosed as the result of a developmental lesion during crown formation, related to systemic stress due to a skull trauma, followed by posteruptive damage from a second traumatic impact. In addition to reconstructing the formation of the defect in the crown of the left M², the paper, for the first time, describes daily and subdaily incremental markings in ursid enamel and provides preliminary information on enamel secretion rate in a cave bear molar.

Muslim religion has strict rules to determine what kinds of foodstuffs, and under what circumstances, are deemed appropriate for consumption. Fishes are not an exception to this rule and features such as body shape or the presence and conspicuousness of scales dictate whether certain species are acceptable or rejected. In this paper, an overview of the Iberian ichthyoarchaeological record from Muslim sites is presented to ascertain whether differences with Christian sites existed in terms of these characters and to what extent these allow one to take fish assemblages as cultural proxies of archaeological deposits. In the case of coastal (production) sites, we also consider whether the peculiarities a given fish assemblage exhibit reflect instead certain environmental features such as the biotopes where a given local fishery operated.

Violence seems to have been a constant in Egyptian history, as attested by documentary sources. The material culture also reflects this state of violence; however, anthropological findings, although present, are not as numerous as might be expected. In the present study, we analyze the injuries found in three crania (New Kingdom, 1500–1070 BCE) from the necropolis of Qubbet el-Hawa, near the island of Elephantine (Aswan, Egypt). All three cases are adult males with several injuries caused by a sharp-edged weapon, with no signs of survival. The macroscopic analysis of the wounds was combined with archaeological and historical data to provide an explanation of the possible weapon used and the possible scenarios (intergroup or intragroup violence) where these deaths could have occurred. These cranial injuries leave no doubt as to the intentionality and repetition in the act of causing death. These findings offer clear evidence and reliable information that contributes to the understanding of interpersonal violence and its potential causes in ancient Egypt.

The conditions of the burial environment trigger microstructural modifications and physical-chemical changes in the bone, such as chemical dissolution, increase of crystallinity, chemical exchanges, collagen degradation and changes in porosity, hence to reproduce these patterns is a challenging task. This work presents a new method to accelerate the diagenetic processes in the laboratory. Artificial aging is obtained by immersion at 80°C in “enriched” solutions derived from the leaching of gravesoils, maintaining the same pH, for 1 month, on modern bones collected from an autopsy. Two distinct solutions from two graves of the necropolis of Travo (IT) (7th–8th century AD) were adopted. The induced damage patterns, on the bone microstructure and the organo-mineral fraction, have been compared with those observed on buried skeletal elements from the same graves, by providing a multi-analytical approach (BSE-SEM, EMPA, FT-IR, MP-AES). Bioapatite parameters, such as crystallinity index and Ca/P molar ratio, evolved similarly and, in some cases, reached the same values of buried bones. Conversely, in the absence of microbial activity, the organic fraction better survived the artificial aging. For the same reason, the porosity due to bioerosion was absent in the artificially aged samples, whereas the biological pores and the post-mortem fractures exhibited the same histomorphology. It is believed that the opportunity of reproducing the diagenetic changes by replicating the chemical environment of the burial site at the laboratory scale is of great interest to forensic science and archaeology (e.g., to reconstruct the burial environment).

There have been archaeological and ethnographic reports of artificially modified crania from all continents. Archaeological excavations at the late fifth millennium BCE cemetery of Tol-e Chega Sofla, located southwest of the Iranian plateau, also revealed these crania. This paper uses the morphometric approach to study Tol-e Chega Sofla's modified crania. The outlines of normal and modified crania of Chega Sofla and Khuzestan residents' specimens were considered. How accurate is the morphometric approach in identifying and recognizing Chega Sofla's modified skulls from normal ones? Can it recognize small variations in the skull's morphology, such as the flattening of the squamous part of the occipital bone? The results of this method can be compared with descriptive studies. Finally, it is shown that the morphometric approach based on Elliptic Fourier Analysis can identify the deformed skull of Chega Sofla and its intensity, as well as the flattening of the squamous part of the occipital bone.

The taphonomy and diagenesis of bone and teeth recovered from any environments provide crucial information for forensic sciences and investigations. This leads to the estimation of the postmortem interval (PMI) and the postmortem submersion interval (PMSI) of the organism/s. Aquatic taxa can induce macroscopic and microscopic alterations in biomineralized tissues (e.g., grooves) or can colonize them by attachment (e.g., Bryozoa). Bryozoa are tiny invertebrates that form colonies in freshwater and saltwater. They can survive for years as suspension feeders in all climates. Most marine Bryozoa species have a biomineralized exoskeleton that can be preserved after their death. This research analyzes eight fragments of archeological elephant ivory with a known PMSI of 314 years, which were inhabited by three distinct bryozoan colonies. The variations in the preservation of the bryozoan exoskeletons and the overgrowth of different marine taxa reveal that one colony (lichenoporid cyclostomatid) was alive at the time of the ivory collection from the submerged archeological site while the two other colonies (cheilostomatid) had previously died at different times. The primary objective of this observation is to contribute to the understanding of the taphonomy of terrestrial mammalian biomineralized tissues recovered in marine environments. Additionally, the study discusses the potential forensic implications of this association, such as the evidence of marine submersion and the PMSI. A secondary objective is to present the Bryozoa colonies within a distinctive depositional context, considering that many bryozoan species of the Western Australian coast remain undescribed. The complexity of the Bryozoa ecobiology is also highlighted, with the need of further research (e.g., minimum time for colonization). Finally, this study highlights the urgency of multidisciplinary collaboration to advance aquatic forensic capabilities.

The development and identification of methods for effective sex estimation of physiologically juvenile remains continue to challenge bioarchaeologists. This systematic review and meta-analysis of investigates the diagnostic accuracy of auricular surface elevation (ASE) for sex estimation of physiological juveniles; determines how the diagnostic accuracy differs between the categorical ASE method and the adapted ranked ASE method; and assesses if the diagnostic accuracy of ASE sex estimation improves with age. ASE sex estimation is used as a component of puberty estimation. A forward search using Google Scholar, SCOPUS, and CrossRef identified 248 unique documents that cited Weaver's original description of the method. The results of more than 700 sex estimates from five peer-reviewed articles and two PhD dissertations are synthesized through bivariate meta-analysis. The bivariate meta-analysis reveals that ASE sex estimation correctly estimates sex of 36.7% [95% CI: 20.8–56.1%] of females and 82.4% [71.9–89.6%] of males. The predictive value of the female auricular surface trait (elevated) is 67.6% [61.8–72.9%], and the predictive value of the male trait (non-elevated) is 56.6% [54.3–58.8%]. When separated into age cohorts of under 1 year old, under 10 years old, and over 10 years old, ASE sex estimation did not show improvement with increased age. This analysis demonstrates that the ASE sex estimation method does not accurately estimate or predict sex of physiologically juvenile individuals, with no improvement from a ranked method or by age. Furthermore, this method should not be used as a component of puberty estimation due to lack of improvement with increasing age-at-death.

Until the 17th century, the Dutch coastal region of Zeeland ranked among Europe's most urbanized areas, driven by thriving international trade networks. People living in this time of flourishing economy benefitted enormously from it in terms of employment opportunities and working conditions, which were reportedly better than in the rest of the Low Countries. However, the rapid growth of Zeeland's urban centers likely presented increasing challenges for the population in terms of accessing essential resources, including food, clean water, and housing. In the 19th century, Zeeland's economy ultimately faced a significant downturn due to the decline in the maritime trade, leading to a substantial reduction in its urban population. Examining patterns of urbanization and economic histories that differ from the commonly studied thriving industrial contexts in bioarcheological research, as exemplified by Zeeland, is a crucial yet relatively underexplored facet in our efforts to understanding the human past. To address this gap, this study investigates the impact of urbanization on the health of Zeeland's inhabitants over time by analyzing nonspecific stress markers (i.e., cribra orbitalia, porotic hyperostosis, and linear enamel hypoplasia) and chronic maxillary sinusitis in a sample of 246 individuals from three urban sites dating from 1030 to 1800 CE. Our analysis of skeletal remains reveals significant differences in the prevalence of porotic hyperostosis, linear enamel hypoplasia, and sinusitis between the medieval and post-medieval periods. These findings suggest that de-urbanization and economic decline adversely affected the health and well-being of the populations under study, influenced by factors such as working conditions and food availability. This study provides a new perspective on bioarcheological approaches to urbanization, shedding light on the intricate realities of urbanization in Zeeland and offering important insights into its complexities.

This article presents the application of Zooarchaeology by Mass Spectrometry (ZooMS) to osseous Longobard artifacts from the collection of the “Musei Reali di Torino” (MRT; Torino, Italy). Like most archaeological items made of worked bone/antler in museum collections, the raw material of such specimens is usually attributed to deer, often without accurate taxonomic attribution. Therefore, the main aim of the present investigation was to shed light on taxonomical aspects using biomolecular approaches.

We first examined the collagen preservation of the artifacts, then we compared three sampling methods (invasive, eraser-based, and bag-based), and we evaluated the quality of the collagen fingerprint obtained. Overall, we found a good, albeit not optimal, biomolecular preservation status, even in heavily restored objects coming from the 19th-century collections.

Out of 37 specimens analyzed through matrix-assisted laser desorption ionization–time of flight–mass spectrometry (MALDI-TOF-MS) and nanoHPLC-tandem MS, 31 yielded usable data. The results confirmed the widespread use of cervid as the osseous raw material for comb-making in Longobard times in Piedmont, but we also found that bovine bones (Bos but also other taxa belonging to family Bovidae, such as caprines) and equid bones were exploited—demonstrating opportunistic use of animal resources. As far as the method is concerned, the ZooMS peptide markers useful to distinguish between bovids and cervids (m/z 1580 vsm/z 1550) (Buckley et al., 2009) are more frequently detected when analyzing bone chips, that is, with the invasive sampling method, rather than collagen extracts obtained using non-invasive techniques. Nonetheless, the eraser method (eZooMS) seems to be a good trade-off between invasivity and quality of the information obtained: eZooMS sampling does not leave visible marks on the object and therefore can contribute to facilitating the routine application of biomolecular methods in the daily practice of museum conservation laboratories. Indeed, an important outcome of the present study has been the establishment of a close collaboration between museum and biomolecular specialists.

Taken together, our results suggest that the Longobards had a preference towards locally available resources, although this work did not highlight a clear association between raw material (deer, cattle, and other bovids) and object typology (in the case of combs) or function, except for buttons. The overall information obtained by this study confirms the potential of biomolecular approaches for reconstructing the biography of museum objects with a long and complex life and demonstrates the value of zooarchaeological study of museum collections.

Porcelain, or calcified, gallbladder is a finding rarely identified in archaeologically excavated remains. This study reports on an ovoid calcification found in the torso of adult skeleton from an early 20th-century mental asylum cemetery in Mississippi. The calcified object was imaged using conventional x-ray and computerized tomographic (CT) scanning (standard and micro), which produced images consistent with those of a clinically diagnosed porcelain gallbladder containing a single large gallstone. The aim of this paper is to raise awareness of this medical condition, which may not be familiar to most anthropologists, and of the efficacy of CT scanning for the identification of calcified gallbladders, which may increase the number of cases reported in archaeological literature and provide more information about the prevalence of this condition, and gallbladder disease in general, in past populations.
