Congratulations to John Murray (Institute of Human Origins, School of Human Evolution and Social Change, Arizona State University; Social Sciences Department, Glendale Community College), the winner of the EAG Laboratories-SAS Student Pilot Research Award! This award is designed to support the collection of preliminary chemical data for use in major funding applications and was newly launched in 2025. SAS is excited to see the results of John's research on silcrete and stone tools and is grateful to Eurofins EAG Laboratories for their support of this award.
“How does geochemistry vary with mineralogy across South African silcrete sources?”
This award will allow John to apply Scanning Electron Microscopy – Energy Dispersive X-ray Spectroscopy (SEM-EDS) to geological thin sections of South African silcrete to better understand how silcrete structure relates to variation in geochemistry. Silcrete was commonly heat-treated and used as a raw material for manufacturing stone tools in the Middle Stone Age of South Africa. Due to its formation processes, the structure and quality of silcrete is highly variable and not all sources respond to heat treatment in the same way. Thus, it is important that we understand the mineralogical structure and geochemistry of archaeologically relevant sources to determine how heat treatment influences these characteristics.
John’s research focuses on better understanding how Middle Stone Age humans heat-treated silcrete on the south coast of South Africa through experimental archaeology, lithic analysis, and machine learning. This research contributes to a long-standing debate surrounding the complexity of the method used to heat-treat silcrete which may have implications regarding human cognition, social learning and teaching, and possibly language. Also, it has provided new pathways to identify heated silcrete in the archaeological record that are non-destructive, quantitative, and field friendly.

We are very pleased to announce that the Journal of Archaeological Science (JAS) and Society for Archaeological Sciences (SAS) Emerging Investigator Award for 2024 has been awarded to Lasse Lukas Platz Herskind for the paper “A computational linguistic methodology for assessing semiotic structure in prehistoric art and the meaning of southern Scandinavian Mesolithic ornamentation”. Follow the DOI for more info: https://doi.org/10.1016/j.jas.2024.105969
The paper was selected as an outstanding example of transdisciplinary work, combining computational methods and Mesolithic non-figurative art with linguistics and semiotics. The study provides a novel approach for analysing ancient semiotic systems through art objects and proposes new methodologies for tackling concepts of symbolism, language and communication in prehistoric societies. The paper serves as a strong example of digital humanities, and has a wider impact on understanding intangible heritage and social connectedness in archaeological research.
Author’s comments
“I remain proud of this publication but am nonetheless overwhelmed by the positive feedback it has received. This computational linguistic approach is hopefully only the first in a series of interdisciplinary novelties to prehistoric art research, and it is my hope that fellow researchers will help me explore, improve, and test these ideas.”
Honorable Mentions

Congratulations to the 2025 awardees of the new Beta-SAS Radiocarbon Dating Award! This annual award is designed to facilitate research into geographically and thematically underrepresented areas of radiocarbon dating. This year’s awardees will push the boundaries of radiocarbon research with an examination of the process of neolithization in the inland regions of the Iberian Peninsula through Bayesian modeling (Estíbaliz Espada-Martín), analysis of insects from a prehistoric cave in Granada, Spain to understand prehistoric funerary activity (Pedro Henríquez Valido), and the establishment of a chronological sequence for Southern Honduras, key for understanding the region and its interactions with Mesoamerica and Southern Central America (Marie Kolbenstetter). Congratulations to Estíbaliz, Pedro, and Marie, and thanks to Beta Analytic for their support of these early career scholars! We look forward to following their results!
Estíbaliz Espada-Martín (Universidad Autónoma de Madrid) "Neolithization of the Iberian Peninsula: Radiocarbon Dating of a Negative Structure in the Middle Tajo Basin (El Congosto, Rivas-Vaciamadrid, Madrid)
The process of neolithization on the Iberian Peninsula has traditionally been studied in coastal regions, with the interior areas being largely overlooked. Recent research, however, has revealed significant cultural diversity within the Meseta, particularly in the middle Tagus basin. This region faces notable chronological challenges due to the scarcity, complicating the establishment of an accurate timeline for the Neolithic period. In response, this project will secure an accurate date for a negative structure located at El Congosto. By analyzing specific samples, the research will integrate the new data into Bayesian models, refining the Neolithic chronological framework. This improved timeline will significantly enhance our understanding of the evolution of cultural and technological traditions in this under-explored part of the Iberian Peninsula, providing new insights into the processes underlying neolithization.
Estíbaliz is currently a PhD candidate funded by the Spanish Ministry of Universities. Her research focuses on Neolithic pottery production from the middle basin of the Tagus River in central Spain. The primary goal of this work is to reconstruct pottery technologies and manufacturing traditions of prehistoric communities in central Iberia. To achieve this, she employs ceramic petrography, X-ray diffraction (XRD), and X-ray fluorescence (XRF). Additionally, she has a strong interest in culinary practices, especially those related to dairy processing and consumption.
Pedro Henríquez Valido (Universidad de Alcalá, Área de Prehistoria) "Dating of insects associated with cadaveric decomposition in a prehistoric context at La Cueva de Los Murciélagos de Albuñol (Granada, Spain)”
The archaeological remains in this cave have been removed as a result of mining activities in the 19th century. However, the preservation of the organic remains in this site is spectacular, which has made it possible to preserve not only insects, but also the remains of arrows and the oldest basketry in Europe. The insects recovered and their chronological contextualization will allow us to know the times of occupation of the cave as a funerary space, but also to try to locate where the cadaveric deposits were located. Pedro’s career has focused on the study of archaeobotanical and archaeoentomological remains in storage contexts. During his thesis he worked on this type of materials in granaries excavated in caves by the indigenous population of the Canary Islands (N.W. Africa continent, Spain), and he is currently studying insects associated with cadaveric decomposition in prehistoric contexts.
Marie Kolbenstetter (Leiden University/Université Paris Nanterre) "Chronology building for precolonial Southern Honduras”
By revisiting eight key sites in Southern Honduras and conducting AMS radiocarbon dating on four of them, the awarded project proposes to reassess the existing cultural sequence for the region and anchor it in absolute chronology. This chronological reassessment will enable a reevaluation of existing archaeological data, and serve as a foundation for future archaeological work in the region. The results will also play an essential role in facilitating regional comparisons with Mesoamerica and Southern Central America. In this, the Beta-SAS Radiocarbon Dating Award provides essential support for building chronology in a region where absolute dating remains sparse. Marie's broader research interests lie with interaction and the construction of local identities in Central America. Her current work explores how both precolonial and modern practices have shaped, and continue to shape, local identities in Southern Honduras, where she has been leading her own archaeological project since 2021. In her dissertation research, she combines data from archaeological and ethnographic fieldwork to investigate how ceramic and lithic technology, ritual practices, and fishing and mollusk harvesting activities contribute to the construction of place, territory, and social landscapes in the Gulf of Fonseca.
