Innovative 'Uranium-Carbonate' Laser-Ablation Methodology Refines the Chronology of Paleolithic 'Stalactite' Art in the Satpura Range to 48,000 Years Ago

Researchers at the Indian Institute of Science have announced a revolutionary dating methodology using Uranium-Carbonate laser ablation to analyze thin mineral crusts covering rock art in the Satpura Range. This technique allows for the dating of pigments with sub-millennial precision without damaging the underlying artwork, pushing the chronology of these symbols back to 48,000 years ago.

This new timeline confirms that symbolic expression in Central India was contemporaneous with similar developments in Europe and Southeast Asia. The research highlights the Satpura Range as a critical corridor for early human cognitive development, demonstrating that the inhabitants were utilizing complex mineral-based pigments to record abstract concepts significantly earlier than previously hypothesized.
