For the last weeks, @paulovaml.bsky.social and I were at the Paläon Museum to study the bone tools from Schöningen. This fantastic collection is crucial for the #ERCStG ExOsTech to understand the origin of bone tools in Europe. @univbordeaux.bsky.social @cnrsecologie.bsky.social @pacea.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

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.
