Medieval fish remains on the Newport ship identified by ZooMS collagen peptide mass fingerprinting
-
Fish represent a key economic, social and ecological group of species that humans have exploited for tens of thousands of years. However, as many fish stocks are going into decline and with little known about the anthropogenic impacts on the health of the marine ecosystem pre-Industrial Revolution, understanding historical and archaeological exploitation of fish species is key to accurately modelling these changes. Here, we explore the potential of collagen peptide mass fingerprinting (also known as Zooarchaeology by Mass Spectrometry, or ZooMS) for identifying fish remains from the Medieval (fifteenth century) Newport ship wreck (Wales, UK), and in doing so we establish a set of biomarkers we consider useful in discriminating between European fish taxa through the inclusion of over 50 reference taxa. The archaeological results identified nine distinct taxonomic groups, dominated by ling (> 40%), and a substantial amount of cod (> 20%) and hake (~ 20%). The vast majority of samples (> 70%) were identified to species level, and the inability to identify the remaining taxonomic groups with confidence using ZooMS was due to the fact that the reference collection, despite being relatively large in comparison to those presented in mammalian studies, reflects only a small proportion of fish biodiversity from this region. Although the results clearly demonstrate the potential for ZooMS as a means of fish bone identification, the sheer number of different fish species that potentially make up ichthyoarchaeological assemblages leads to obvious requirements for the analysis on much greater numbers of modern reference specimens, or the acquisition of collagen sequences.

Historical management of equine resources in France from the Iron Age to the Modern Period
-
Alongside horses, donkeys and their first-generation hybrids represent members of the Equidae family known for their social, economic and symbolic importance in protohistoric and historical France. However, their relative importance and their respective roles in different regions and time periods are difficult to assess based on textual, iconographic and archaeological evidence. This is both due to incomplete, partial and scattered historical sources and difficulties to accurately assign fragmentary archaeological remains at the proper taxonomic level. DNA- based methods, however, allow for a robust identification of the taxonomic status of ancient equine osseous material from minimal sequence data. Here, we leveraged shallow ancient DNA sequencing and the dedicated Zonkey computational pipeline to obtain the first baseline distribution for horses, mules and donkeys in France from the Iron Age to the Modern period. Our collection includes a total of 873 ancient specimens spanning 128 ubiquitous and the most dominant species identified, our dataset reveals the importance of mule breeding during Roman times, especially between the 1st and 3rd centuries CE (Common Era), where they represented between 20.0% and 34.2% of equine assemblages. In contrast, donkeys were almost absent from northern France as-semblages during the whole Roman period, but replaced mules in rural and urban commercial and economic centers from the early Middle Ages. Our work also identified donkeys of exceptional size during Late Antiquity, which calls for a deep reassessment of the true morphological space of past equine species. This study confirmed the general preference toward horses throughout all time periods investigated but revealed dynamic manage-ment strategies leveraging the whole breadth of equine resources in various social, geographic and temporal contexts.

Sex in the city: uncovering sex-specific management of equine resources from prehistoric times to the modern period in France
-
Sex identification from fragmentary archeozoological assemblages is particularly challenging in the Equid family, including for horses, donkeys and their hybrids. This limitation has precluded in-depth investigations of sex-ratio variation in various temporal, geographic and social contexts. Recently, shallow DNA sequencing has offered an economical solution to equine sex determination, even in environments where DNA preservation conditions is not optimal. In this study, we applied state-of-the-art methods in ancient DNA-based equine sex determination to 897 osseous remains in order to assess whether equal proportions of males and females could be found in a range of archeological contexts in France. We found Magdalenian horse hunt not focused on isolated bachelors, and Upper Paleolithic habitats and natural traps equally balancing sex ratios. In contrast, Iron Age sacrificial rituals appeared to have been preferentially oriented to male horses and this practice extended into the Roman Period. During Antiquity, the Middle Ages and the Modern Period, cities emerged as environments largely dominated by horse males. This strong sex-bias was considerably reduced, and sometimes even absent, in various rural contexts. Combined with previous archaeozoological work and textual evidence, our results portray an urban economy fueled by adult, often old, males, and rural environments where females and subadults of both sexes were maintained to sustain production demands.
