The paper “A closer look at an eroded dune landscape: first functional insights into the Federmessergruppen site of Lommel-Maatheide” [1] focuses on the final Palaeolithic (Federmesser) site of Lommel-Maatheide. Federmesser sites from northern Belgium such as Lommel-Maatheide, Meer and Rekem, show evidence for dense human occupation of specific areas located on top of Tardiglacial dunes nearby water bodies [2]. Preserved spatial distribution of finds at the sites suggest different activity areas and the presence of habitat structures [2]. However, because of the low organic preservation at the sites, functional analyses of lithic assemblages have the potential to significantly contribute to the spatial organisation of activities at these sites. This study by Tomasso et al. [1], represents an excellent example of a large-scale integrated approach to the study of lithic industries. The article undoubtedly demonstrates the potential of the proposed methodology and the reliability of the results obtained.

The article explores two different aspects (linked and excellently interconnected here): the possibility to apply use wear, residue and fracture analyses, on lithic assemblages affected by taphonomical alterations and to study lithic assemblages from dune landscapes. 

The study allows to answer differentiated questions: what is the influence of taphonomical alterations on use wear analysis? How do excavation methods impact the formation of use wear and the preservation of residues? Can we recognize distinct domestic activities? The article also provides an interesting hypothesis about hunting activities and propulsion methods.

The applied methodology is effectively interdisciplinary and innovative. It demonstrates how a truly integrated and articulated approach can represent the turning point for going beyond a mainly descriptive dimension to move towards a real understanding of the sites.

Studies dedicated to the analysis of the propulsion mode are not very frequent, but they are surely very important to better understand human behaviour [3]. Here, the methodology developed for the evaluation of the propulsion mode represent an important starting point for the definition of a new approach. Morphological and morphometrical analysis are integrated to the evaluation of the mechanical stress, to fracture delineations and to the hafting system (the latter defined on experimental basis).

This article therefore underlines the potential of combining different approaches to functional analysis associated with a ‘tailored’ reference collection and applying them to a high number of artefacts for reconstructing past human activities involving materials that are otherwise not preserved in these contexts.

The paper entitled “Platforms of Palaeolithic knappers reveal complex linguistic abilities” [1] submitted by C. Gaucherel and C. Noûs represents an interesting reflection about the possibilities to detect the human cognitive abilities in relation to the lithic production.

The definition and the study of human cognitive abilities during the Lower Palaeolithic it has always been a complex field of investigation. The relation between the technical skills (lithic production) and the emergence of the linguistic abilities is not easy to investigate due to the difficulty of finding objective data to refer to. The proposition, made by C. Gaucherel and C. Noûs, of a formal grammar of knapping as a method to study the syntactical organisation of the reduction sequences, constitute a new and theoretical useful approach.

In order to effectively and precisely define the gestures linked to a specific reduction sequence, for example that of the handaxes shaping, a very large number of variables should be taken into consideration (morphology and quality of the raw material, experience of the knapper, context, percussion technique, forecast of use of the handaxe, etc.). But since a simplification, that brings more elements than the classic one [2,3] is needed, the “action grammar approach” can be a good instrument to detect the common element in a shaping reduction sequence. Furthermore, one of the advantages of the proposed methodology lies in the fact that the definition of the different STs (Stone Technology) can be done according to the technological specific characteristics to be studied and to the type of instrument produced.

The deconstruction of knapping sequences could help to detect the degree of complexity of the different steps of the reduction sequences also thanks to the identification of the sub-actions types. The increasing/decreasing of complexity is a very complicate concept in lithic technology. Since at the base of the lithic production there are two basic concepts (angle between the striking platform and the debitage surface - convexity of the debitage/façonnage surface) which are simply declined in an increasingly complex way, it is not easy to define uniquely in what exactly consists the increase in complexity. The approach proposed in the paper “Platforms of Palaeolithic knappers reveal complex linguistic abilities” can help to have new evidences, according to the identification of the required cognitive abilities.

The proposed example of formal grammar still needs to be confirmed on archaeological collections, but it is probable that a practical application will allow to further develop the methodology and possibly to highlight additional possibilities of the approach.

The Middle Palaeolithic period represents a crucial phase in the Prehistory of Europe, marked by the dominance of Neanderthal populations and their adaptive strategies. In Portugal, this period is characterized by a wealth of archaeological sites that provide valuable insights into the lifeways, technology, and environmental adaptations of its inhabitants (Aubry et al., 2011; J. L. Cardoso & Cascalheira, 2024; Cascalheira et al., 2022; Zilhão, 2001; Zilhão et al., 2021). One of the most significant is Gruta da Figueira Brava, located near the modern coastline: recent research has highlighted its role as a key site for understanding coastal adaptation by Neanderthals (Zilhão et al., 2020). Almonda Cave System is another pivotal area (Marks et al., 2001; Marks et al., 1994), offering a long stratigraphic sequence that includes Middle Palaeolithic layers . A prominent site is also and Foz do Enxarrique (Cunha et al., 2019), rich in lithic artifacts indicating a reliance on local hunting and foraging . The lithic technology of the Middle Palaeolithic in Portugal is largely characterized by the widespread use of the Levallois method, with variations reflecting local adaptations and raw material availability. Quartz, quartzite and flint were commonly used, indicating a strategic selection of materials based on functionality and proximity.

The Côa Valley, located in northern Portugal, is renowned for its rich archaeological record spanning from the Middle Palaeolithic to the Upper Palaeolithic (Aubry et al., 2012, 2016). The region’s significance lies not only in its rock art but also in its evidence of human occupation and technological development during the Pleistocene. Middle Palaeolithic sites in the Côa Valley are characterized by lithic assemblages associated with Neanderthal populations. These sites reveal a predominance of quartzite and flint tools, typical of Middle Palaeolithic technology. Excavations at sites like Cardina-Salto do Boi have uncovered stratified deposits with stone tools and faunal remains, shedding light on subsistence strategies and mobility patterns. As shown by the work presented by Patricia Ramos & Thierry Aubry, the tools from these layers exhibit a range of core reduction techniques, including Levallois flaking. The chosen approach for studying the lithic assemblage emphasizes the significance of raw materials in defining the technological behaviours employed by Neanderthal groups. Specifically, the study highlights the intensive use of quartz as a primary resource. The classification of different types of quartz, based on defined criteria and categories, reveals variations in material selection and technological practices across the analysed layers. This detailed analysis allows for a deeper interpretation of the technological strategies adopted by Neanderthal groups at the Cardina-Salto do Boi site. The work of Patricia Ramose and Thierry Aubry demonstrates how the Middle Palaeolithic record of the Côa Valley continues to provide interesting insights into Neanderthal life in the Iberian Peninsula.
