Palaeoproteomic analysis of skeletal remains from Grotta Guattari (Italy)
Excavations at Grotta Guattari (Italy; 66–65 ka) in the previously unexplored Antro del Laghetto area uncovered numerous morphologically unidentified skeletal remains from both the cave’s internal (aquatic) and external (dry) sectors, providing an opportunity to investigate how contrasting depositional environments influence protein preservation. Taxonomic identifications were attempted using MALDI-ToF ( n = 200) and LC-MS/MS (n = 490 ). LC-MS/MS…
Complementarity between morphological and proteomic taxonomic identification methods of Late Upper Palaeolithic and Early Neolithic bone fragments from the NE Iberian Peninsula
Zooarchaeology by Mass Spectrometry (ZooMS) has been widely used for taxonomic identification of fragmented bones, yet most direct comparisons with morphological identifications originate from European Palaeolithic contexts. This study provides a general assessment of the two taxonomic identification approaches of one Late Upper Palaeolithic and three Early Neolithic bone assemblages, all located in the northeastern Iberian Peninsula. The results…
Contextualising the La Ferrassie 1 Homo neanderthalensis skeleton through palaeoproteomic analysis and radiocarbon dating
The La Ferrassie site, a reference locality for Neandertal paleobiology and Middle-to-Upper Paleolithic transition, has yielded numerous hominin remains over more than a century of excavations. Among them, the La Ferrassie 1 (LF1) skeleton, discovered in 1909, is one of the most complete individuals attributed to Homo neanderthalensis . Nevertheless, its precise stratigraphic context and chronological attribution remain uncertain due to outdated …

Ancient biomolecular analysis of 39 mammoth individuals from Kostenki 11-Ia elucidates Upper Palaeolithic human resource use
Circular structures made from woolly mammoth bones are found across Ukraine and west Russia, yet the origin of the bones remains uncertain. We present ten new mammoth radiocarbon dates from the largest circular structure at Kostenki 11-Ia, identifying two mammoth mandibles ∼200–1200 years older than the other dated materials from the site, suggesting skeletal material from long-dead individuals was scavenged and used in the site construction. Bio…
Composition variations in archaeological human bone proteomes
Sampling strategies within the field of skeletal palaeoproteomics are often based on specimen availability. Knowledge of bone biology might assist in improving sample selection strategies and minimise unnecessary sampling of precious (hominin) material. We study ten bone sample locations across four bone elements, for a total of 10 adult, archaeological human skeletons. We compare bone proteome composition and modification for skeletal elements f…
Cleaning the dead
The study of ancient proteins preserved in a range of archaeological, cultural heritage, and palaeontological materials is increasingly contributing to our understanding of human evolution and archaeological research questions. Many of the specimens studied have been excavated and stored for a significant duration prior to their proteomic analysis. Human handling and storage environments therefore provide ample opportunities for protein contamina…
Early Holocene preservation differences between cortical and trabecular bone proteomes
Skeletal sample selection for evolutionary palaeoproteomic studies is currently based on the availability of material, without taking into account the influence of bone biology on the proteome composition of living bone. A prime example concerns the cortical and trabecular bone that is present simultaneously in many skeletal elements, including those recovered from archaeological sites. These two bone components are formed and maintained in diffe…
A comparative study of commercially available, minimally invasive, sampling methods on Early Neolithic humeri analysed via palaeoproteomics
Due to methodological advances in the archaeological sciences, an increasing number of archaeological specimens undergo destructive sampling. However, the preservation of cultural heritage is a primary concern. This leads to a dilemma between accessing sample material and obtaining sufficient information for a meaningful analytical outcome. Ideally, sampling a specimen would preserve the object for further macro, micro, and molecular analyses. Fo…

Moving away from 'the Muddle in the Middle' toward solving the Chibanian puzzle
Using ZooMS to assess archaeozoological insights and unravel human subsistence behaviour at La Viña rock shelter (northern Iberia)
The highly fragmented nature of Palaeolithic faunal assemblages is a regular limitation in archaeozoological analyses as it prevents a precise taxonomic identification following comparative anatomy criteria. In this paper, we integrate Zooarchaeology by Mass Spectrometry (ZooMS) analysis of unidentifiable bone fragments within archaeozoological and taphonomic data to overcome this limitation and disentangle the subsistence strategies of Solutrean…
Identifying the unidentified fauna enhances insights into hominin subsistence strategies during the Middle to Upper Palaeolithic transition
Understanding Palaeolithic hominin subsistence strategies requires the comprehensive taxonomic identification of faunal remains. The high fragmentation of Late Pleistocene faunal assemblages often prevents proper taxonomic identification based on bone morphology. It has been assumed that the morphologically unidentifiable component of the faunal assemblage would reflect the taxonomic abundances of the morphologically identified portion. In this s…
Methodological advances in Neanderthal identification, phylogeny, chronology, mobility, climate, and diet
The Late Middle Palaeolithic Occupation of Abri du Maras (Layer 1, Neronian, Southeast France)
The exact strategies and technologies underlying Neanderthal hunting events remain open for debate with lithic points being sparse across the European Middle Palaeolithic. An exception is the Neronian entity in southeast France, defined by ventrally retouched Soyons points. This study contextualises one of the largest Neronian assemblages, layer 1 at Abri du Maras. Our lithic analyses focussed on attributes described as indicative of projectile u…

Recherches pluridisciplinaires sur la sépulture de l'enfant néandertalien La Ferrassie 8
L’ancienneté des premières sépultures primaires en pleine terre et leur ou leurs auteurs sont des problématiques débattues depuis la naissance de la Préhistoire. En effet, enterrer volontairement un mort, ce qui implique probablement une considération conceptuelle qui échappe largement aux archéologues, est une activité symbolique que certains n’associent qu’à Homo sapiens. Nous fournissons de nouvelles informations multidisciplinaires sur le con…

Human and cervid osseous materials used for barbed point manufacture in Mesolithic Doggerland
Barbed bone points originally deposited in Doggerland are regularly collected from the shores of the Netherlands. Their typology and direct 14C dating suggest they are of Mesolithic age. However, the species of which the barbed points were made cannot be identified based on morphological criteria. The bones used to produce the barbed points have been intensively modified during manufacture, use, and post-depositional processes. Here, we taxonomic…

Variations in glutamine deamidation for a Châtelperronian bone assemblage as measured by peptide mass fingerprinting of collagen
Peptide mass fingerprinting of bone collagen (ZooMS) has previously been proposed as a method to calculate the extent of the non-enzymatic degradation of glutamine into glutamic acid (deamidation). Temporal and spatial variation of glutamine deamidation at a single site, however, has not been investigated. Here we apply ZooMS screening of Châtelperronian and Early Holocene bone specimens from Quinçay, France, to explore temporal and spatial varia…
Analysis of coprolites from the extinct mountain goat Myotragus balearicus
Humans colonized the Balearic Islands 5–4 ka ago. They arrived in a uniquely adapted ecosystem with the Balearic mountain goat Myotragus balearicus (Bovidae, Antilopinae, Caprini) as the only large mammal. This mammal went extinct rapidly after human arrival. Several hypotheses have been proposed to explain the extinction of M. balearicus . For the present study ancient DNA analysis (Sanger sequencing, Roche-454, Ion Torrent), and pollen and macr…
