📸 Random photos: visit to Bacho Kiro Cave, and team shots celebrating 30 years of collaboration between Bulgaria and PACEA.

The event brought together researchers from 14 nationalities, from Europe to Japan, through Central Asia and the Near East.
It concluded on a moving note as L. Iakovleva (Kyiv) reminded us of the challenges of doing science amid geopolitical turmoil — ending with a heartfelt “Vive la paix!” 🇫🇷🕊️

This inspiring meeting, supported by the GPR Human Past and my project Threads, was initiated by our dear colleague T. Tsanova, a former PACEA PhD student.
It celebrated her rediscovery of Bacho Kiro Cave and her findings showing H. sapiens in SE Europe 45 ka ago.

With @lucdoyon.bsky.social , we discussed how beads and bone tool technology can help trace the dispersal of Homo sapiens across Eurasia.
Our colleague N. Zwyns (PACEA) shared new insights on the IUP in mainland Asia (~45 ka), and P. Zhang (PACEA) presented on stone tool tech in China MIS 3.

Pleased to share my latest article
Beads of shells and teeth from Abri Murat (Rocamadour, Lot) reveal long-distance networks linking Atlantic, Mediterranean, and inland groups 15,000+ years ago @cnrsecologie.bsky.social @univbordeaux.bsky.social

#PressRelease 🗞️ The oldest workshop for making shell jewellery has been unearthed at the Palaeolithic site of La Roche-à-Pierrot. 🐚

👉 www.cnrs.fr/en/press/old...

🐚 The littorina, characterized by a wide range of natural colors when fresh, originate from the Atlantic coast, situated about 100 km away from La Roche-à-Pierrot at the time of the occupation (7/20)

🐚 🔬Microscopic analyses by @solangerigaud.bsky.social revealed that perforated shells show no wear, and pigment staining comes from nearby hematite. With 14 intact shells, little/no wear, and high fragmentation, the evidence supports a shell ornament workshop (8/20)

Châtelperronian cultural diversity at its western limits: Shell beads and pigments from La Roche-à-Pierrot, Saint-Césaire | PNAS The timing and mechanisms underlying the gradual replacement of Neanderthal populations by Homo sapiens groups have elicited heated debate for deca...

shorturl.at/JDZYs We report a shell-bead workshop at Saint-Césaire (Fr) and suggest that Châtelperronian makers were influenced by, or part of, an early wave of H. sapiens in the region 42ka @univbordeaux.bsky.social @cnrsecologie.bsky.social

🧪Saint-Césaire annual fieldwork led by I. Crevecoeur. A key site to debates on the Middle-to-Upper Paleolithic transition.
I’m reassessing the Upper Paleo artefacts as part of my Threads project @univbordeaux.bsky.social @pacea.bsky.social @cnrsecologie.bsky.social @nouvelleaquitaine.bsky.social

Excited to welcome Céline, a Master's student from ULiège, for a training stay at @pacea.bsky.social with me, Biba Hromodova and @lucdoyon.bsky.social ! Her project deals with ivory industry from Goyet & Spy. @cnrsecologie.bsky.social @univbordeaux.bsky.social

Last week’s interdisciplinary residency at Maison Bordes, Les Eyzies, with PhD students & postdocs from Sci Archéo & Environnement. Great practice in non-specialist writing & reflecting on societal relevance. River swims & a ride back to Bordeaux! @cnrsecologie.bsky.social @univbordeaux.bsky.social

Multivariate analyses of Aurignacian and Gravettian personal ornaments support cultural continuity in the Early Upper Palaeolithic Traditionally, lithic artefacts have served as the principal proxy for the definition of archaeological cultures in the Upper Paleolithic. However, the culture-historical framework in use, constructed...

Just out! we challenge the long-standing tradition of defining Upper Paleolithic cultures primarily through stone tool artefacts. Instead, we turn to personal ornaments to explore cultural identities during the past shorturl.at/8mxKe @univbordeaux.bsky.social @cnrsecologie.bsky.social

🚨 Join the PACEA Laboratory! The CNRS @cnrsecologie.bsky.social is recruiting a senior postdoc (3 to 6-year contract) to work on Pleistocene and Holocene paleoenvironments. This is part of a long-term strategy and may lead to a permanent full-time research position emploi.cnrs.fr/Offres/CPJ/C...

From the field in Cyprus: traditional tribulum at our host’s place. This was a common threshing tool in Mediterranean agriculture until recently. Flint flakes and cores to produce them frequently found during surveys with @umr5608traces.bsky.social @nxcco.bsky.social @cnrsecologie.bsky.social

At the Musée National de Préhistoire, Les Eyzies, exploring how Azilian foragers adorned their bodies 14ky ago. Convenient stay at La Maison Bordes @univbordeaux.bsky.social facility welcoming scholars from around the world for over 30 years, right across from the museum @cnrsecologie.bsky.social

For the past 3 days, I’ve been at the Fyssen with @mariesoressi.bsky.social invited to speak on cooperation in human evolution—alongside archaeologists, primatologists & philosophers. I discuss how did innovation, identity & otherness shape us @univbordeaux.bsky.social @cnrsecologie.bsky.social

Smithsonian attaquée par Trump Les Musées de la Smithsonian Institution visés par une attaque de Trump et menacés de se voir privés de financement s’ils ne se plient pas à l’idéologie raciste du Président des USA.

The Words Federal Agencies Are Discouraged From Using Under Trump Federal agencies have issued guidance to employees on hundreds of terms to limit or avoid using. An analysis of government websites shows many of the same words being removed.
