In other rock-related news, Europe's oldest known intentional cave engravings were unearthed in France in 2023. Archaeologists found eight panels in La Roche-Cotard cave, which lies some 150 miles (240km) southwest of Paris in the Loire Valley, showing more than 400 Neanderthal 'finger flutings' (indents made by fingers smudged into the sediment). At between 57,000 and 75,000 years old, the panels are among the most ancient engravings ever found.
