20,000 Years Old 3D Map Discovered in Cave Near Paris.
French scientists have identified a unique engraving in the Ségognole 3 cave, located in the famous sandstone massif south of Paris. This engraving, dating back to the Upper Paleolithic, could be the oldest three-dimensional map ever found.
The carved motifs and their relationship with natural features in the sandstone of the shelter can be compared with major geomorphological features in the surrounding landscape. The engraved floor is not quite a map but more like a model in miniature of the surrounding landscape, potentially a world-first 3D model of a Paleolithic territory.

As water flowed into the cave through fissures in the ceiling, it would have traveled along the paths of the engravings, filling in depressions, basins, and other waterways, much in the way that rain outside the cave would have affected the local environment.
