Even the heatwave can't stop us! 🔥 Today, experiments are underway testing heat treated silcrete projectiles with different hafting orientations. 👀

More exciting research! A new publication by Justin Coppe and Veerle Rots explores how morphometric interpretations influence evolutionary models of prehistoric weaponry and challenges long-standing assumptions about projectile technology. Read the article here: doi.org/10.48738/202...

The project ”Experiment-based approach to Middle Stone Age artisanship at Rose Cottage Cave” strikes again. Funded by a Research Grant from The Leakey Foundation, we continue to investigate lithic technology between 100-30 ka at this reference Stone Age site in South Africa.

This work is fundamental to deepening our knowledge about tool manufacture and subsistence of past hunter-gatherers within their social structures and habitats through functional and technological analyses.

Collaborators on the project are Dr Noora Taipale (FNRS, TraceoLab), Dr Viola Schmid (TraceoLab, Austrian Academy of Sciences, University of Vienna, University of the Witwatersrand), and Prof. Lyn Wadley (ESI, University of the Witwatersrand).

Our latest knapping adventure took us to Leiden, where Dr. Morgan Roussel from Paleocraft and Skills demonstrated his expertise. He crafted various blanks from siliceous stones sourced from ancient river terraces near Rose Cottage Cave and western Lesotho.

Dr Roussel used thin, elongated blanks to apply diverse techniques of backing and larger, thicker elements to pressure flake them with the horn of a roan antelope into points with basal ventral thinning.

We’re pleased to announce that Dr Julien d’Huy will give a lecture on Wednesday 17th entitled Remonter les mythes pour éclairer le temps : comment comprendre l'art des cavernes durant le Paléolithique supérieur ?

What better way to end CONEXP than with a series of experimental demonstrations? Thank you to all of our participants and to the Préhistomuseum, it has been such an enriching and engaging experience. We hope you enjoyed it as much as we did!

That’s a wrap on Day 3! Another fantastic day filled with incredible presentations — a big thank you goes out to all of our presenters and attendees. We can’t wait to see you all tomorrow for a full day of experimental archaeology demonstrations at the Préhistomuseum!

What an amazing second day at CONEXP 2025! It’s been an inspiring day filled with presentations, discussions, cultural activities, and fresh perspectives on diverse topics. We’re excited for tomorrow! #conexp2025

Conexp 2025 has started! We look forward to four days of interesting talks, cool posters and exciting experimental demonstrations. Our keynote speaker Miguel Biard tells about the fascinating experiments related to the large blade production at the famous Magdalenian site of Etiolles.

We are deeply involved in the craft of producing natural fibers, utilising Wommersom quartzite tools to manage brambles, just like Mesolithic hunter-gatherers may have done 10,000 years ago! 🌿🪨 #syntheseonderzoekarcheologie

This study focuses on knapping techniques. It describes the microscopic traces associated with knapping and shows how they can be combined with macroscopic traces to strengthen the identification of knapping techniques.

The results suggest that, based on such a combination, it is possible to identify the use of percussion (direct and indirect) and pressure, as well as to differentiate between the use of harder and softer contact tools.

The Lommel–Molse Nete is one of the most extensive and best-preserved Federmesser sites in north-western Europe. This unique Late Glacial site offers exceptional opportunities to explore how hunter-gatherer groups at the end of the Ice Age organised their lives and adapted to changing environments.

Our research will combine detailed techno-functional analysis of stone tools (including residue analysis), raw material provenance studies, and intrasite spatial analysis of activity areas and site organisation.

Exciting progress today in our Synthesis project on Mesolithic mobility in the Demer Basin! With Vincent Delvigne ((CNRS and UMR Temps 8068), we're building a flint raw materials library and using petrographic analysis to trace prehistoric movement. 🔍🪨

📢📢 LAST CALL – DEADLINE FOR ABSTRACT SUBMISSIONS! 💀🕒 ⏳ FINAL DEADLINE: 31 July — Submit your proposal for oral presentations, posters, or demonstrations at the 🎓 7th International Congress of Experimental Archaeology (CONEXP 2025) | 📅 22–25 October 2025 We can’t wait to welcome you to Liège! 🤩🔥

UMR TEMPS and TraceoLab are hosting the conference 'On the Traces of Prehistoric Individuals: Scientific Challenges, Methods, and Perspectives' in Paris on 26-27 February 2026. Abstract submissions are open and should be sent to pierre.allard@cnrs.fr, solene.denis@cnrs.fr or otouze@uliege.be.

Bullseye! This week at TraceoLab, more than fifty sharp projectiles were launched as part of a summer study on wear patterns. This initiative aims to establish a benchmark for Lola's PhD, which focuses on identifying the components of laterally hafted projectiles.
