Article Reference Fish δ13C and δ15N results from two Bronze/Iron Age sites (Tell Tweini & Sidon) along the Levantine coast
Stable isotope ratio measurements of fish remains from archaeological sites are relatively rare so here we report results of 201 fish remains from two Bronze and Iron Age sites along the Syrian (Tell Tweini) and Lebanese (Sidon) coast to document the inter- and intra-specific variation of the δ13C and δ15N isotope values. Due to poor preservation, successful isotopic results were only obtained from 42 specimens (21%). Our results were combined with previously published fish isotopic results from Sidon (n = 16) so that a total 58 specimens representing 16 different fish taxa are presented. A wide variation was observed between species that appears to be related to the ecology of the fish, in particular their salinity tolerance and feeding behaviour. The largest intra-specific variation was observed in mullets (Mugilidae) and seabreams (Sparidae) in both δ13C and δ15N values, and it appears, after comparison with published data from the Northern Aegean, some clustering occurs with location. However, the data clustering is not discrete enough to allow provenancing of fish remains from archaeological sites in this region. This large series of fish isotope values can also serve as an isotopic baseline for other studies, including the dietary reconstruction of Eastern Mediterranean human remains.

Article Reference Ancient West African foragers in the context of African population history
Our knowledge of ancient human population structure in sub-Saharan Africa, particularly prior to the advent of food production, remains limited. Here we report genome-wide DNA data from four children—two of whom were buried approximately 8,000 years ago and two 3,000 years ago—from Shum Laka (Cameroon), one of the earliest known archaeological sites within the probable homeland of the Bantu language group1–11. One individual carried the deeply divergent Y chromosome haplogroup A00, which today is found almost exclusively in the same region12,13. However, the genome-wide ancestry profiles of all four individuals are most similar to those of present-day hunter-gatherers from western Central Africa, which implies that populations in western Cameroon today—as well as speakers of Bantu languages from across the continent—are not descended substantially from the population represented by these four people. We infer an Africa-wide phylogeny that features widespread admixture and three prominent radiations, including one that gave rise to at least four major lineages deep in the history of modern humans.

Article Reference New mtDNA and Isotopic Evidence on Late Pleistocene Cave Bears in the Balkans: the Case-study of Magura Cave, NW Bulgaria
Recent genetic studies have shed light on the phylogeography of cave bears; however, their paleoecology and their diet are still debated, and data from south-eastern Europe are still scarce. Magura Cave, in northwest Bulgaria, has delivered rich faunal assemblages from the Late Pleistocene. The chronology of the excavated area spans from ca. 35 kya to more than 50 kya; the oldest stratigraphic layers being associated with final Middle Palaeolithic tools. The fauna comprises herbivores and carnivores, and potentially different taxa of cave bears, the dental remains of which also showed different tooth morphotypes, suggesting the co-existence of different dietary adaptations. We investigated the mitochondrial DNA (mtDNA) lineages of the cave bears from Magura Cave as well as the stable carbon and nitrogen isotope composition of the faunal assemblage. Our data revealed that, regardless of the tooth morphotypes, only maternal lineages of Ursus ingressus were present in Magura Cave. Interestingly, one specimen with Ursus arctos mtDNA was also found, showing a clear carnivore diet. In contrast, the U. ingressus specimens had a predominantly herbivorous diet. The tooth morphotypes were associated with significantly different δ13C values, suggesting different dietary adaptations.

Article Reference Anatomy, Relationships, and Paleobiology of Cambaytherium (Mammalia, Perissodactylamorpha, Anthracobunia) from the lower Eocene of western India
The anatomy of Cambaytherium, a primitive, perissodactyl-like mammal from the lower Eocene Cambay Shale Formation of Gujarat, India, is described in detail on the basis of more than 350 specimens that represent almost the entire dentition and the skeleton. Cambaytherium combines plesiomorphic traits typical of archaic ungulates such as phenacodontids with derived traits characteristic of early perissodactyls. Cambaytherium was a subcursorial animal better adapted for running than phenacodontids but less specialized than early perissodactyls. The cheek teeth are bunodont with large upper molar conules, not lophodont as in early perissodactyls; like perissodactyls, however, the lower molars have twinned metaconids and m3 has an extended hypoconulid lobe. A steep wear gradient with heavy wear in the middle of the tooth row suggests an abrasive herbivorous diet. Three species of Cambaytherium are recognized: C. thewissi (∼23 kg), C. gracilis (∼10 kg), and C. marinus (∼99 kg). Body masses were estimated from tooth size and long bone dimensions. Biostratigraphic and isotopic evidence indicates an age of ca. 54.5 Ma for the Cambay Shale vertebrate fauna, the oldest Cenozoic continental vertebrate assemblage from India, near or prior to the initial collision with Asia. Cambaytheriidae (also including Nakusia and Perissobune) and Anthracobunidae are sister taxa, constituting the clade Anthracobunia, which is sister to Perissodactyla. We unite them in a new higher taxon, Perissodactylamorpha. The antiquity and occurrence of Cambaytherium—the most primitive known perissodactylamorph—in India near or before its collision with Asia suggest that Perissodactyla evolved during the Paleocene on the Indian Plate or in peripheral areas of southern or southwestern Asia.

Article Reference An interdisciplinary study around the reliquary of the late cardinal Jacques de Vitry
The reliquary of Jacques de Vitry, a prominent clergyman and theologian in the early 13th century, has experienced several transfers over the last centuries, which seriously question the attribution of the remains to the late Cardinal. Uncertainty about the year of his birth poses an additional question regarding his age at death in 1240. The reliquary, located in the Saint Marie d’Oigines church, Belgium, was reopened in 2015 for an interdisciplinary study around his relics as well as the Treasure of Oignies, a remarkable cultural heritage notably built from Jacques de Vitry’s donation. Anthropological, isotopic and genetic analyses were performed independently on the remains found in the reliquary. Results of the analyses provided evidence that the likelihood that these remains are those of Jacques de Vitry is very high: the remains belong to the same human male individual and the historical tradition about his age is confirmed. In addition, a separate relic (left tibia) was analysed and found to match with the remains of the reliquary (right tibia). The unique Jacques de Vitry’s mitre, made of parchment, was sampled non-destructively and the extracted parchment collagen was analysed by a proteomic method in order to determine the animal species. The results showed that, surprisingly, not all parts of the mitre were made from the same species. All together, these findings are expected to fertilize knowledge carried by historical tradition around the relics of Jacques de Vitry and his related cultural heritage.

Article Reference Throwing Activities Among Neolithic Populations from the Meuse River Basin (Belgium, 4500–2500 BC) with a Focus on Adolescents.
The anterior band of the medial collateral ligament (MCL) is an important stabilizer for valgus stress at the elbow. When practised intensively and repetitively, activities using overhead throwing motions can injure this ligament and its insertion. If these activities occur when the epiphyses are not yet fully fused, traction forces can result in bony detachments in the area of the MCL insertion. This study was based on commingled graves found in 16 Middle and Late Neolithic caves from Belgium. We recorded the presence of MCL lesions on 196 humeri and studied the relation between lesions, siding, and robusticity. 5.1% of the humeri displayed MCL lesions, which affected only the right robust humeri. Our results suggest a social division in throwing activities in Belgium during the Neolithic. They also suggest that throwing practice started from a young age, which invites us to re-examine the role of teenagers in prehistoric societies.
