					<description><![CDATA[Researchers identified common eland collagen in a 60,000-year-old ochre-rich archaeological surface at South Africa's Kilpdrift Complex using mass-spectrometry-based palaeoproteomics.]]></description>
										<content:encoded><![CDATA[<p>Researchers have detected common eland collagen in an ochre-rich archaeological surface dating to about 60,000 years ago at the Kilpdrift Complex in South Africa. The team from Kyushu University, the University of Bergen and the University of Copenhagen reported the finding in Proceedings of the Royal Society B, describing it as biomolecular evidence that animal-derived material was associated with ochre use during the Middle Stone Age. The researchers proposed two possible explanations: animal-derived materials were deliberately mixed with the ochre, or ochre-treated eland hides were present at the site.</p>
<p>The Kilpdrift Complex lies within the coastal cliffs of the De Hoop Nature Reserve and is a Middle and Later Stone Age archaeological site. Investigators analysed archived sediment samples taken from the ochre-rich surface in an experimental palaeoproteomic study. Because the recovered proteins were not readily visible, the researchers used molecular analysis to identify their animal source. The analysis found type I collagen assigned to the common eland, Taurotragus oryx, providing evidence that eland material had been associated with the archaeological deposit.</p>
<p>Proteins were extracted from the sediment and separated and analysed using liquid chromatography-tandem mass spectrometry, commonly abbreviated LC-MS/MS. This method breaks extracted proteins into measurable peptide fragments. The resulting fragments were compared with large protein databases and a custom collagen reference database to determine the species of origin. The eland identification was based on this biomolecular comparison, allowing researchers to detect animal material that could not be characterized by visual examination of the sediment alone.</p>
<p>The successful recovery of identifiable collagen from archaeological sediment demonstrates a potential role for palaeoproteomics at sites where ancient DNA rarely survives. Ancient proteins can therefore supplement other forms of archaeological analysis by revealing biological traces associated with otherwise inconspicuous deposits. In this case, the method recovered eland collagen from a challenging African environment and documented an association between animal material and ochre use. The study does not establish the precise origin of the collagen, whether it was intentionally added to the ochre, or whether the deposit reflects a specific technical or symbolic activity.</p>
<p>Evidence of organic components mixed with ochre has been extremely rare in Africa, according to the research report, making the eland collagen an unusual addition to the record of Middle Stone Age behaviour. The authors interpret the association as evidence of the complex technical and possibly symbolic behaviours of early Homo sapiens, but they acknowledge that the protein evidence alone cannot distinguish between deliberate mixing and the presence of ochre-treated hides. Further archaeological context would be needed to determine the sequence of events that created the deposit and the function of the ochre and animal material. The principal demonstrated result is therefore the identification of common eland collagen in approximately 60,000-year-old ochre-rich sediment through palaeoproteomic analysis.</p>

					<description><![CDATA[A comprehensive analysis of personal ornaments from Foradada cave sheds new light on the technological skill and social networks of Early Upper Palaeolithic hunter-gatherers in eastern Iberia.]]></description>
										<content:encoded><![CDATA[<p>Deep inside a sea-facing cave near the town of Xàbia on Spain&#8217;s eastern coast, archaeologists have uncovered a collection of small but extraordinarily revealing objects: perforated animal teeth and mollusc shells that once adorned the bodies of some of the earliest modern humans to settle the Iberian Peninsula. A new study of the personal ornaments from Cova Foradada, published in Archaeological and Anthropological Sciences, offers one of the most detailed portraits yet of how these Early Upper Palaeolithic hunter-gatherers chose, made, wore and discarded their jewellery, and it hints at shared cultural identities that stretched across the eastern Mediterranean seaboard of Iberia.</p>
<p>Personal ornamentation is far more than decoration. To archaeologists, beads and pendants are a vital proxy for symbolic behaviour and technological complexity, encapsulating everything from raw material collection and environmental knowledge to manufacturing skill and patterns of use and discard. As one of the hallmark expressions of Homo sapiens arriving in Europe, ornaments are especially crucial for investigating the technological knowledge and non-utilitarian practices of the first modern human groups on the Iberian Peninsula. Yet detailed functional analyses of such assemblages remain surprisingly scarce, which is what makes the Foradada study stand out.</p>
<p>The research team, led by Oriol Montero-Buch of the Universitat d&#8217;Alacant together with Ester Verdún-Castelló, Magdalena Gómez-Puche, Josep A. Casabó and Javier Fernández-López de Pablo, subdivided the cave&#8217;s ornament record into three distinct assemblages using stratigraphic and contextual criteria: an Early Upper Palaeolithic group, a mixed Upper Palaeolithic group and a Holocene group. This careful separation allowed the researchers to focus on the earliest phase, when modern humans were first establishing themselves in the region, while acknowledging the complexities introduced by later occupations of the cave.</p>
<p>The assemblage comprises thirty-five finished ornaments, alongside elements related to technical failures and accumulations of raw material. That combination is exceptionally informative, because it captures the entire life history of ornament production rather than just the end products. The range of materials selected is impressively broad, stretching from terrestrial mammal teeth to both marine and freshwater mollusc shells. This diversity suggests that the cave&#8217;s inhabitants possessed an intimate understanding of multiple ecological zones, from inland hunting territories to the nearby coastline, and deliberately targeted specific raw materials for ornamental purposes.</p>
<p>To unlock the secrets of these objects, the team employed a combined technological and traceological approach. Technological analysis examines the chaîne opératoire, the sequence of operations involved in producing each ornament, from raw material selection through perforation to final finishing. Traceology, or use-wear analysis, reads the microscopic marks left on the surfaces of the objects, revealing how they were suspended, how they moved against one another or against clothing, and how they ultimately came to be discarded. Together, these methods allowed the researchers to characterise the full biography of each bead and pendant, from manufacture through use to disposal.</p>
<p>Perhaps the most striking finding came from Raman spectroscopy, a non-destructive analytical technique that identifies mineral compounds by the way they scatter laser light. This analysis identified evidence of colour modification technology on the ornaments, meaning that some of the beads or shells had been deliberately treated to alter their colour, most likely with iron oxide pigments such as ochre. This represents one of the earliest documented uses of such colour modification on personal ornaments during the Early Upper Palaeolithic in the Iberian Peninsula, adding the region to the growing map of early pigment use across Eurasia and underscoring that these small objects carried aesthetic and symbolic significance that went beyond their natural appearance.</p>
<p>Comparative analysis with nearby regional ornamental assemblages revealed clear similarities between Foradada and other contemporary collections in the surrounding region. In the study of early modern human groups, ornament types can function rather like cultural fingerprints, and such shared patterns potentially point to common social networks and ethno-cultural identities linking communities across eastern Iberia. Recent large-scale European studies of Aurignacian and Gravettian ornaments have suggested that distinct ornamental traditions may correspond to distinct cultural groups, and the Foradada material now contributes an important data point from the Iberian Mediterranean margins to this emerging continental picture.</p>
<p>The researchers argue that the Foradada assemblage constitutes a significant collection of personal ornaments on the Iberian Peninsula during the Early Upper Palaeolithic, a period for which well-preserved and well-studied ornament assemblages remain comparatively rare in this part of Europe. The cave&#8217;s location, close to what would have been a dramatically different Late Pleistocene coastline, makes it a particularly valuable window onto how early coastal hunter-gatherer communities integrated marine resources, both dietary and symbolic, into their lives. Previous work at the site has already documented shellfish consumption during this period, and the ornament study now shows that shells also served as vehicles of identity and meaning.</p>
<p>Beyond its regional importance, the study makes a methodological case that is likely to resonate across Palaeolithic archaeology. The authors assess the potential value of integrating techno-functional analysis with spectroscopic methods as a way to add evidence on hunter-gatherer procurement strategies and their relationship with the environment. By combining microscopic reading of manufacturing and wear traces with mineralogical identification of pigment residues, archaeologists can extract far richer narratives from small ornamental objects than either technique alone could provide. Applied more widely, this integrated approach promises to illuminate not only how beads were made and used, but also where their raw materials came from, how far they may have travelled, and what that can reveal about the mobility and exchange networks of Europe&#8217;s earliest modern human societies.</p>
<p>For now, the ornaments of Cova Foradada stand as quiet testimony to a world nearly forty millennia past: a time when small groups of modern humans, perched between mountains and a cold sea on the edge of Europe, were already investing time, skill and meaning in the objects they wore against their skin. In their perforated teeth and pigmented shells, the first Iberian sapiens left behind a durable record of who they were, who they knew, and how they wished to be seen.</p>
