We are back in #Botswana for our researches about Human origins. So wonderful caves to explore and new sites to discover with the Botswana National Museum team. #archaeology #karst #geomorphology #geology #Africa #paleontology @cnrs.fr @cnrs.fr @umr5608traces.bsky.social @cnrsecologie.bsky.social

Tsunami in Lake du Bourget 200 years ago!! Our paper investigate the 1822 earthquake and resulting tsunami with a maximum wave of 2.5m and seiche for 4 days! This numerical model allow us to propose the mecanism at the origin of Homogenite @edytem.bsky.social www.sciencedirect.com/science/arti...

We’re deeply concerned about the disappearance of our colleague Pierre Noiret. Please share and help us spread the word. For more information please check: www.police.be/avis-de-rech...

It was a pleasure to lead a team of karst scientists in Sterkfontein caves #SouthAfrica, in the framework of the #karst record 10 international conference. We discussed about flowstone, #stratigraphy and #dating @umr5608traces.bsky.social @cnrs.fr #geology #geomorphology #archaeology #paleontology

🚀 Today is the day! The #LHOSA project funded by the @AgenceRecherche officially kicks off. Excited for the journey ahead! 👉http://palevoprim.labo.univ-poitiers.fr/language/en/2025/04/01/lhosa/ @palevoprim.bsky.social @cnrsecologie.bsky.social @univpoitiers.bsky.social

🦴 Cave environments affect bone at the Galería site (Spain) over 300ka. Lowest levels <3% survival - heavy rainfall 🌧️ ➡️ acid soils leach away bone. As climate dries, preservation improves ML 🤖 89% classification Link: www.nature.com/articles/s41... #archaeology #taphonomy #geochemistry

A four-panel (A-D) conceptual model showing the evolution of bone preservation conditions in the Galería cave site across different Marine Isotope Stages (MIS). Each panel includes a cross-section of cave deposits and chemical pathways.
Panel A (GIIa, MIS10a): Shows waterlogged, acidic conditions (660-620mm/year rainfall) with extensive bone leaching and formation of phosphate minerals.
Panel B (GIIb, MIS9d): Depicts drier conditions (600mm/year) with partial bone leaching and CaCO3 migration.
Panel C (GIIIa, MIS9c): Illustrates a transition from wet to dry (560-530mm/year) with increasing alkalinity and calcite precipitation.
Panel D (GIIIb-GIV, MIS8-MIS7e): Shows cold, arid conditions (520-420mm/year) with intense calcite precipitation and fluorine incorporation in bones.
Each panel includes chemical reaction pathways shown with blue arrows, and red arrows indicate key depositional processes. The diagrams show how environmental changes affected bone preservation through time.
