This engraved stone artifact was found in a recent technological analysis of the stone tool assemblage unearthed at the Shuidonggou site in 1980. It is the first engraved non-organic artifact from the entire Paleolithic of China.
Archaeologists used a digital microscope to observe all the incisions and obtain 3D images. After excluding the possibility of natural cracking, trampling and animal-induced damage, and unintentional human by-products, they believed that the incisions were made by intentional behavior.
