  • Analysis of organic residues in the context of the middle bronze age in the northwestern Iberian Peninsula: the case of the Cova da Moura funerary monument (Viana do Castelo, nw Portugal)
    Publication . Oliveira, Nuno; Oliveira, César; Bettencourt, Ana M. S.; Costa, Cláudia
    This paper presents and discusses the results of chromatographic analyses conducted on the contents of a ceramic pot recovered from Cova da Moura, a coastal funerary context located on the western slope of the Serra de Santa Luzia in Carreço, within the municipality and district of Viana do Castelo, Northwest Portugal. The site was excavated in 1931 by Abel Viana, who uncovered a monument beneath a tumulus that concealed a cluster of granite outcrops with numerous cavities (tafoni). Depositional activities in these cavities revealed several artifacts, including fragments of various ceramic containers, metal and glass objects, knapped and polished stone tools, animal remains, a diverse assemblage of plant-derived charcoal, and at least one anthropomorphic stele. The materials exhibit a wide chronological range, with the earliest occupation dating from the Late Middle Bronze Age (circa 15th-14th century BCE) and the most recent from the Late Iron Age. Among these finds was a fragmented ceramic pot containing organic residues at its internal base, dated from the regional Bronze Age. Chromatographic analysis of these residues identified traces of animal meat, possibly from monogastric species, and plant oils, both of which appear to have been exposed to high temperatures. This study represents the first application of organic chemical analysis to a ceramic vessel from a plausible Middle Bronze Age funerary context in Northwestern Portugal. The findings suggest the presence of commensal rituals or the deposition of prepared meat offerings as part of funerary practices.

  • Anthony E. Marks (1938–2025): pioneer of the palaeolithic
    Publication . Rose, Jeffrey Ian; Bicho, Nuno; Usyk, Vitaly I.; Winchell, Frank
    Anthony “Tony” Edward Marks passed away on August 15, 2025, at his home in Santa Fe, New Mexico, at the age of 87. Tony’s passing marks the end of a remarkable career in archaeology that spanned nine countries, four continents, and a quarter million years of prehistory. Not only did he fundamentally shape how we understand the Palaeolithic record, but he transformed our very perception of lithic technology, teaching us how to find the profound depth of meaning in stone. A proud New Yorker, Tony was born, raised, and edu¬cated in Manhattan. As a young student at Columbia Uni¬versity eager to pursue his love of European medieval art and churches, he was promptly taken aside by the anthropol¬ogy department head, Marvin Harris, who (rather forcefully as Tony would recall) urged him to stick with archaeology. Tony’s professional career began with the UNESCO Nubian salvage campaigns of the 1960s. As Lake Nasser rose behind the Aswan High Dam, Tony mapped prehistoric sites along the east bank of the Nile before their inundation. During the Nubian salvage project, he documented several key Palaeo¬lithic industries, including an array of assemblages defined by the presence of Nubian core technology. He could never know at the time how that discovery would unexpectedly resurface decades later, at the end of his career.

  • Archery technology in the neolithic: management of the mediterranean mixed forest and woodworking activities at La Marmotta (Italy)
    Publication . L, Caruso Fermé; Monteiro, Patrícia; V, Brizzi; M, Mineo; G, Remolins; N, Mazzucco; B, Morell; F, Gibaja J.
    Although Neolithic communities were characterized by an agricultural economy, the presence of bows in their archaeological record demonstrates the persistence of hunting activities. At La Marmotta, an underwater Early Neolithic site located in Lake Bracciano (Anguillara Sabazia, Italy), a considerable assemblage of preserved wooden tools was discovered some of them related to hunting activities demonstrating their reliance on woodland resources for technological purposes. Since wood was the main raw material for ancient bows, understanding how it was exploited is fundamental for reconstructing archery technology in prehistory. Here, we present the archaeobotanical analyses of 19 wooden bows found in La Marmotta. Taxonomic analysis identified the wood used as Carpinus sp. (9), Viburnum lantana (6), Alnus sp. (1), Cornus sp. (1), Fraxinus sp. (1), and evergreen Quercus sp. (1). The mechanical properties of these species are compatible with the crafting and use of bows although they are not the most usual wood, as shown by the archaeological record of Neolithic bows. This taxonomic diversity suggests that there was not a specific selection of wood based on mechanical/physical properties, which is coherent with La Marmotta wood acquisition modalities for the production of other tools and structures.

  • Châtelperronian cultural diversity at its western limits: shell beads and pigments from La Roche-à-Pierrot, Saint-Césaire.
    Publication . Bachellerie, François; Gravina, Brad; Rigaud, Solange; Dayet, Laure; Thomas, Marc; Lebreton, Loïc; Morin, Eugène; Lesage, Camille; Falguères, Christophe; Bard, Edouard; Bahain, Jean-Jacques; Baillet, Mickaël; Beauval, Cédric; Bordes, Jean-Guillaume; Culioli, Gérald; Devièse, Thibaut; Flas, Damien; Garbé, Lisa; Guérin, Guillaume; Lacrampe-Cuyaubère, François; Lahaye, Christelle; Mallol, Carolina; Marot, Josserand; Maureille, Bruno; Michel, Alexandre; Muth, Xavier; Regniers, Olivier; Tartar, Elise; Teyssandier, Nicolas; Thibeault, Adrien; Todisco, Dominique; Tombret, Olivier; Rougier, Hélène; Crevecoeur, Isabelle
    The timing and mechanisms underlying the gradual replacement of Neanderthal populations by groups have elicited heated debate for decades. The Châtelperronian of France and northern Spain has figured prominently in these discussions. While the Neanderthal authorship of this techno-complex is far less certain than previously thought, the Châtelperronian is now generally accepted as being among the first genuine Upper Paleolithic industries in Eurasia rather than a "transitional" stone tool technology. Here, we report the first association of shell beads with Châtelperronian artifacts from new excavations at the site of La-Roche-à-Pierrot, Saint-Césaire (France), supported by a multiproxy spatial analysis that incorporates site formation processes. Similar types of personal ornaments are unknown from Middle Paleolithic contexts. Comparable examples have, however, been recovered from contexts penecontemporaneous with the Châtelperronian in south-eastern Europe and around the Mediterranean. This hitherto undocumented combination of an early Upper Paleolithic industry and shell beads provides insights into cultural variability in western Europe and raises the question as to whether the makers of the Châtelperronian were influenced by or formed part of the earliest dispersals of into the region.

  • A comparison of tool-use flexibility between captive chimpanzees and bonobos
    Publication . Bandini, Elisa; Harrison, Rachel; Hrubesch, Christine; Forss, Sofia
    Despite chimpanzees and bonobos sharing close phylogenetic ties to humans, chimpanzees are the more common model species in multiple fields of comparative research. One reason for this bias is the variation in tool repertoire size observed between the two species. Previous studies have examined the factors driving this difference, but few have targeted flexibility in how tools are used. We studied bonobos and chimpanzees under similar conditions in captivity, thus excluding any ecological variation present in these species’ natural habitats. We examined whether the species differed in their ability to switch between tools, a trait that may facilitate tool innovation in primates. To do so, we provided the apes with a task that required switching tool type from a rigid stick to a bendable rope to forage successfully. Our data suggest that there are no significant differences in tool-use performance between chimpanzees and bonobos in captivity. However, we found significant differences in the species’ exploration tendencies. While chimpanzees fixed their attention on stick tools, bonobos switched their attention more easily towards the rope, potentially due to less functional fixedness. We also found significant within-species differences between institutions. These findings suggest that future research should disentangle intrinsic flexibility in exploration and account for institution and group level effects.

  • Deciphering the diet of the iberian iynx: insights from taphonomic analysis of pleistocene coprolites
    Publication . Rufà, Anna; Sanz, Montserrat; Daura, Joan
    Pleistocene deposits often result from multiple and overlapping contributions. Carnivores play a significant role as bone accumulators in archaeological sites, but identifying the specific agent responsible for a particular accumulation can be challenging. Referential studies provide valuable insights into bone accumulation patterns, but they are based on modern collections and often fail to account for taphonomic biases associated with site formation processes. Here, we present, for the first time, a taphonomic study focused on fossilised Pleistocene Iberian lynx coprolites within the European context. The assemblage, dated to ca. 33 ky B.P., was recovered from layer III of Cova del Gegant, a site identified as a lynx den likely used for rearing cubs. This study is based on previous research at the site and analyses bone remains consumed by the Iberian lynx (Lynx pardinus), recovered from coprolites, to investigate their role in archaeological contexts. The findings are consistent with other lynx accumulations documented in literature, particularly regarding leporid remains. The anatomical proportions in this assemblage are more balanced than other types of accumulations, with a higher representation of cranial elements. Digestive damage is predominant, affecting most bones, especially at moderate and strong degrees. These results enhance our understanding of archaeological accumulation processes and highlight the role of lynxes as bone accumulators. The archaeological evidence from the site indicates that the Iberian lynx inhabited environments and climates that differ significantly from those currently observed. However, the present study suggests that its diet remained relatively consistent with that of contemporary Iberian populations.

  • The dichotomy of human decision-making: an experimental assessment of stone tool efficiency
    Publication . Cabrita Nora, David André; Marreiros, Joao; Gneisinger, Walter; Pedergnana, Antonella; Pereira, Telmo; Enza Elena Spinapolice
    The physical properties of distinct raw materials, such as hardness, homogeneity, and grain size, have been recurrently suggested as some of the key reasons for human decision-making, namely the selection, production, and use of stone implements in the past. However, little is known, concerning the relationship between stone tools and human behaviour and how this is reflected in the variability seen in the archaeological record. Therefore, investigating stone tools’ properties and performance brings fundamental insights into identifying and understanding the origins of some of the major human technological behavioural traits. In this study, we aim to address this topic by measuring the variability of the properties of lithic raw materials from the perspective of tool use. A controlled experiment was designed to test the mechanical performance with a focus on the efficiency (ratio between effectiveness and durability) of four distinct raw materials (quartzite, dacite, flint, and obsidian). Our study addresses the null hypothesis: “Edge efficiency does not vary according to the different lithic raw materials.” Efficiency is assessedby the combination of penetration depth (proxy to measure effectiveness) and edge wear (proxy to measure durability). These two variables were measured, and the results correlated with the physical properties of various raw materials, including hardness and grain size. Our results show significant differences in the efficiency between the different types of raw materials. The outcome demonstrates that the variables by which we test the edge efficiency of lithic raw materials are highly relevant for raw material selection and, consequently, may have been of utmost importance in influencing the decision-aking process of past hunter-gatherers. A decrease in tool efficiency during use may have constrained daily activities, necessitating technological adaptations. This strongly suggests that each raw material used in archaeological contexts to produce blanks should be evaluated for its efficiency. In addition, it may be pertinent to extend this approach to other blunt artefactssuch as scrapers, burins, anvils, and hammerstones when investigating aspects of interconnected behaviours such as artefact variability, resource economy, group mobility, and site function. Such choices and decisions are coded in the archaeological record and represent cultural factors that were transmitted through learning and likely triggered the human decision-making process of past hunter-gatherers.

  • Earliest evidence for intentional cremation of human remains in Africa
    Publication . Cerezo-Román, Jessica I.; Sawchuk, Elizabeth; Schilt, Flora Cecilia; Bertacchi, Alex; Buckley, Gina; Chibisa, Edwin; Fahey, B. Patrick; Falchenberg, Sofia Gunilla Hedman; Kaliba, Potiphar; Kennett, Douglas J.; Mercader, Julio; Pargeter, Justin; Stock, Jay; Szymanski, Ryan; Thompson, Jessica C.
    Human cremation on an open pyre demands intensive labor, communal resources, and sensory exposures. We report the earliest evidence for intentional cremation in Africa, the oldest in situ adult pyre in the world, and one of only a few associated with hunter-gatherers. A large cremation feature at Hora 1 in Malawi dates to similar to 9500 years ago and contains the remains of a small, gracile adult with evidence for perimortem defleshing and postcremation manipulation. Subsequent revisiting of the site to build fires in the same place provided additional pyrotechnological spectacles. High-resolution, multiproxy reconstruction of the ritual associated with cremation and its subsequent deposition demonstrates complex mortuary practices among ancient African foraging groups with substantial social investment and use of natural landscape features as persistent mortuary monuments.

  • Functional analysis of the lithic assemblage of Gombore IB (Melka Kunture, Ethiopia): looking for traces of use, but finding post-depositional problems
    Publication . Bello-Alonso, Patricia; Serodio, Andrea; Marreiros, Joao
    Early Stone Age (ESA) archaeological complexes pose significant challenges for traceological analysis due to the preservation conditions of their contexts. At Gombore I (Melka Kunture, Ethiopia), lithic materials attributed to Level B are often associated with flood-prone or riparian zones, and thus subject to post-depositional alterations such as aeolian abrasion and trampling. Additionally, the diversity and nature of raw materials, mainly volcanic rocks like obsidian and basalt, further complicate use-wear studies. In this study we present preliminary findings from the Gombore IB lithic assemblage, which is attributed to the ESA, with significant levels associated with the Acheulean technocomplex. Initial sampling, based on visual inspection, prioritized artefacts deemed suitable for traceology. However, macro- and microscopic analyses revealed extensive surface alterations, limiting the preservation of use-wear traces and rendering traditional analysis unviable. Our research therefore focused on developing a broader analytical framework which could use these preservation issues for interpretations on site formation processes in the archaeological record. By employing dedicated experimental protocols to compare with the archaeological assemblage, this study establishes an initial use-wear pattern associated with postdepositional alteration. The lithic assemblage from Gombore IB offers valuable insights, which we apply to interpret the site’s formation processes. These data, in conjunction with spatial analyses, yield promising results and highlight the value of integrating preservation assessments into traceological studies, emphasizing the importance of context in interpreting ESA archaeological records.

  • Geoarchaeological insights into a Neolithic combustion feature from Abric del Xicotó (northeastern Iberia)
    Publication . Fernández-Palacios, Enrique; Égüez, Natalia; González-Olivares, Cynthia; Herrera-Herrera, Antonio V.; Mallol, Carolina; Mangado, Xavier; Sánchez de la Torre, Marta
    The Neolithic was a period of important cultural transformations across different regions. Applying state-ofthe-art geoarchaeological techniques to archaeological sites from this period has shown to contribute relevant data on site formation processes and occupation dynamics. Combined microcontextual and biomolecular analysis of archaeological combustion features helps us approach fuel use, often associated to dung residues in Neolithic contexts, which offer an insight into herding strategies. Here, we present micromorphological, microremains (fecal spherulites, ash pseudomorphs, and phytoliths), and biomarker data (n-alkanes, fecal sterols, and bile acids) obtained from a Neolithic combustion feature at Abric del Xicoto´ (Alo` s de Balaguer, Lleida, Spain). Preliminary data shed light on the functionality of the combustion feature, the presence of husbandry activity at the rockshelter, and the nature of the animals and their diet. This research adds detail to the existing Neolithic archaeological record of the northeastern Iberian Peninsula.
