We introduce the M/OTHERING dataset, an open-access resource for researchers exploring the social and religious dimensions of ancient Italy and beyond. This dataset lists metadata for 2,725 terracotta votive figurines depicting adults with subadults, dating from 625 to 27 BCE, and originating from the historical regions of Etruria, Latium, Magna Graecia, and Sicilia. The upper limit of 27 BCE was chosen to coincide with the end of the Roman Repub…
Two Migration Period Graves from Slatiňany, Chrudim District
In 2019, during archaeological rescue excavations preceding the construction of the Slatiňany bypass, two inhumation graves dating back to the 5th century AD (stages D2 and D3 of the Migration Period) were discovered. The aim of the paper is to present the results of comprehensive interdisciplinary cooperation (anthropology, archaeozoology, metallography, genetics, textile studies, and chemical, elemental, and isotope analyses). The study focuses…
Bayesian estimates of the marine radiocarbon reservoir effect during the Magdalenian in northern Iberia
Quantifying marine reservoir effects (MREs) across time and space is crucial for establishing accurate archaeological chronologies, including the activities of past hominines. Although the northern Iberian Peninsula shows a high density of Upper Paleolithic sites and marine shells are frequently found in these assemblages, quantification of MREs in this coastal region remains limited. We performed Bayesian modeling of radiocarbon measurements fro…
Renewed Archaeological Research in Singida Region, Central Tanzania
Archaeological research in central Tanzania, chiefly in the Singida Region, has only been sporadically conducted, with the focus of such investigations being mostly on rock art and Later Stone Age (LSA) material. Here, we report preliminary results from renewed research expeditions conducted in the Singida Region. In 2021 and 2022, we located 31 archaeological sites in Ikungi District, excavated an open-air site (Nkungi) and a rock shelter (Itram…

A problemática do vírus da imunodeficiência humana (VIH) e síndrome de imunodeficiência adquirida (SIDA) está geralmente confinada a uma perspetiva biomédica. São poucos os casos de investigação sobre a participação das entidades com peso na intervenção comunitária, como as associações de cariz comunitário que apoiam pessoas que vivem com VIH e SIDA. O estudo apresentado foca-se no projeto português VIHVER, que investiu na criação de parcerias en…
The Emergence of Interdisciplinary Environmental History
With the efflorescence of palaeoscientific approaches to the past, historians have been confronted with a wealth of new evidence on both human and natural phenomena, from human disease and migration to landscape change and climate. These new data require a rewriting of our narratives of the past, questioning what constitutes an authoritative historical source and who is entitled to recount history to contemporary societies. Humanities-based histo…

The dataset, consisting of 1234 entries, lists the location, spatial coordinates, type of the site/building/marker, chronological range, and relevant scholarly references for each entry. Synecdemus Novus is a resource f…
Expedient Bayesian prediction of subfossil bone protein content using portable ATR-FTIR data
Rapid and minimally destructive methods for estimating the endogenous organic content of subfossil bone save time, lab consumables, and valuable ancient materials. Fourier transform infrared (FTIR) spectroscopy is an established method to estimate bone protein content, and portable spectroscopes enable field applications. We review the ability of benchtop and portable FTIR indices to predict %N and %collagen from 137 bone specimens drawn from eig…
Living in the shore
Recent research on human exploitation of molluscs, echinoderms and crustaceans during the Mesolithic in the Cantabrian region (northern Iberia) has shown significant variability in the intensity of the use of coastal resources by the last hunter-fisher-gatherers throughout the ~ 4000-year expanse of the Mesolithic (10,700 - 6,700 cal BP). Previous studies have proposed hypotheses related to demographic changes to explain intensification events. I…

Presenting the RomAniDat data community and an archaeofaunal dataset for Roman Italy
Stable isotope reconstruction of the "Mediterranean" diet throughout the millennia
Human and animal bones, as well as botanical remains recovered from archaeological sites, preserve the carbon, nitrogen and sulphur (δ13C, δ15N, δ34S) signatures of their last years of life. These isotope ratios are connected to the protein portion of the diet and can be used to investigate the dietary strategies of past populations. Several studies have already been undertaken on this topic across the Mediterranean basin. This paper aims at reco…

AfriArch is an archaeological and paleoenvironmental data community designed to integrate datasets related to human-environmental interactions in Holocene Africa. Here we present a dataset of bioarchaeological stable isotope (C/N/O) and radiocarbon measurements from African archaeological sites spanning the Holocene. Modern measurements, when reported together with archaeological data in original publications, are also included. The dataset consi…
Multidisciplinary investigation reveals an individual of West African origin buried in a Portuguese Mesolithic shell midden four centuries ago
Cabeço da Amoreira is a well-studied shell midden with a robust chronology based on a large number of radiocarbon dates on Mesolithic human burials. Surprisingly, we discovered one individual that lived about 400 years ago buried in this site. We employed a multidisciplinary approach integrating archaeology, historical records, genetics, radiocarbon dating and stable isotope analysis to investigate the biogeographic origins of this individual and…
Excavations at the Iron Age Village Site of Fibobe II, Central Zambia
The period from c. AD 900 to AD 1300 in southern Africa is characterized by transitions from small-scale Iron Age mixed economy communities to the beginnings of more intensive food production and eventually the emergence of complex polities. In Zambia, this coincides with the appearance of larger and more permanent agro-pastoralist villages that began participating in Indian Ocean trade networks. Unlike other parts of southern Africa where stone …
Demography, trade and state power
Hunter–gatherer occupations of small islands are rare in world prehistory and it is widely accepted that island settlement is facilitated by agriculture. The Ryukyu Islands contradict that understanding on two counts: not only did they have a long history of hunter–gatherer settlement, but they also have a very late date for the onset of agriculture, which only reached the archipelago between the eighth and thirteenth centuries AD. Here, we combi…
Multi-isotopic study of the earliest mediaeval inhabitants of Santiago de Compostela (Galicia, Spain)
Santiago de Compostela is, together with Rome and Jerusalem, one of the three main pilgrimage and religious centres for Catholicism. The belief that the remains of St James the Great, one of the twelve apostles of Jesus Christ, is buried there has stimulated, since their reported discovery in the 9th century AD, a significant flow of people from across the European continent and beyond. Little is known about the practical experiences of people li…

Temporal and spatial variability of bone collagen stable carbon and nitrogen isotopic ratios of Norwegian reindeer
Invisible Burials” and Fragmentation Practices in Iron Age Europe
The scarcity of burial remains in large parts of Iron Age Europe, particularly in the Atlantic regions, has often led scholars to discuss the apparent “invisibility” of graves. This paper presents the results from several excavation campaigns at Monte Bernorio, one of the most important sites of the 1st millennium b.c. on the Iberian Peninsula. The fieldwork and post-excavation work carried out in the area of the necropolis have identified numero…
Investigating infant feeding strategies at Roman Bainesse through Bayesian modelling of incremental dentine isotopic data
We present the first study employing Bayesian modelling of isotopic measurements on dentine increments (five human upper first molars) to address Romano-British infant feeding practices at Bainesse (UK). The stable carbon and nitrogen isotope results modelled to 6-month intervals with novel OsteoBioR software revealed some common patterns, with weaning not starting before the age of 6 months and higher animal protein consumption after the age of …
Macronutrient-based model for dietary carbon routing in bone collagen and bioapatite
Quantitative diet reconstruction of a Neolithic population using a Bayesian mixing model (FRUITS)
Objectives The island cemetery site of Ostorf (Germany) consists of individual human graves containing Funnel Beaker ceramics dating to the Early or Middle Neolithic. However, previous isotope and radiocarbon analysis demonstrated that the Ostorf individuals had a diet rich in freshwater fish. The present study was undertaken to quantitatively reconstruct the diet of the Ostorf population and establish if dietary habits are consistent with the tr…
Towards the use of radiocarbon as a dietary proxy
Radiocarbon reservoir effects (RREs) are observed when the 14C concentration of aquatic reservoirs is lower than the contemporary atmosphere. Within these reservoirs, aquatic species will also have a 14C depleted signal, and humans feeding on these species will show a dietary RRE. Human dietary RREs are often viewed as a problem for the establishment of reliable chronologies. However, they also represent an opportunity to introduce radiocarbon as…
A Simple(R) Model to Predict the Source of Dietary Carbon in Individual Consumers
Quantitative individual human diet reconstruction using isotopic data and a Bayesian approach typically requires the inclusion of several model parameters, such as individual isotopic data, isotopic and macronutrient composition of food groups, diet-to-tissue isotopic offsets and dietary routing. In an archaeological context, sparse data may hamper a widespread application of such models. However, simpler models may be proposed to address specifi…
Testing an Alternative High‐throughput Tool for Investigating Bone Diagenesis
Archaeological bone undergoes alterations after burial (diagenesis) that constitute a problem for the survival of archaeological information. A common method to assess this alteration is Fourier transform infrared spectrometry (FTIR). However, the commonly applied method (FTIR–KBr) is destructive and sample preparation may influence the results. This paper tests the suitability of FTIR attenuated total reflection (FTIR–ATR), a method not commonly…
A preliminary study on the influence of cooking on the C and N isotopic composition of multiple organic fractions of fish (mackerel and haddock)
Mussels with Meat
Local reservoir ages are often estimated from the difference between the radiocarbon ages of aquatic material and associated terrestrial samples for which no reservoir effect is expected. Frequently, the selected aquatic material consists of bivalve shells that are typically well preserved in the archaeological record. For instance, large shell middens attest to the importance of mussel consumption at both coastal and inland sites. However, diffe…
A Freshwater Lake Saga
Recently, several case studies have demonstrated the presence of human radiocarbon dietary reservoir effects in inland contexts. Freshwater reservoir effects present a high degree of variability, making it difficult to define local reservoir effect reference values necessary for correcting chronologies based on 14 C dating of human bone material. Here, we investigate the hypothesis that 14 C ages of edible freshwater species are delimited by the …

Confronting chronic shocks
While much of the literature on social resilience is concerned with how cities overcome “shocks” to the urban system, much less is known about the strategies of survival and adaptation among its poorest residents. We argue that residents in poor, often informal, neighborhoods are faced with chronic shocks, or constantly recurring disasters, such as floods, severe illness, or violent police invasions. In this paper, we draw on focus groups, partic…

Subsistence Continuity Linked to Consumption of Marine Protein in the Formative Period in the Interfluvic Coast of Northern Chile
From material culture evidence dating as early as 7500 cal BC, it has been established that populations from the interfluvic coast in northern Chile adapted to a maritime economic livelihood. During the 2nd millennium BC, local populations began to experience major social changes arising mainly from an increase in contacts with agropastoral populations from the highlands of the Andes. New radiocarbon data and stable isotope (δ 15 N col , δ 13 C c…
Much ado about nothing
The effects of the 4.2 kya climatic event on northern Mesopotamia have been the subject of significant scholarly debate, with the notion of a megadrought that forced local populations to migrate attracting particular attention. Here, the authors analyse stable carbon (δ13C) and nitrogen (δ15N) isotopes in human tooth and bone samples to assess trends in subsistence practice at three sites in Syria before, during and after the presumed megadrought…

HIV-related stigma within communities of gay men
While stigma associated with HIV infection is well recognised, there is limited information on the impact of HIV-related stigma between men who have sex with men and within communities of gay men. The consequences of HIV-related stigma can be personal and community-wide, including impacts on mood and emotional well-being, prevention, testing behaviour, and mental and general health. This review of the literature reports a growing division between…

Food Reconstruction Using Isotopic Transferred Signals (FRUITS)
Human and animal diet reconstruction studies that rely on tissue chemical signatures aim at providing estimates on the relative intake of potential food groups. However, several sources of uncertainty need to be considered when handling data. Bayesian mixing models provide a natural platform to handle diverse sources of uncertainty while allowing the user to contribute with prior expert information. The Bayesian mixing model FRUITS (Food Reconstr…
