Eolith from France. Once believed to be an early hammerstone, in 1905 Marcellin Boule debunked its man-made status[1]
A geofact (a portmanteau of geology and artifact) is a natural stone formation that is difficult to distinguish from a man-made artifact. Geofacts could be fluvially reworked and be misinterpreted as an artifact, especially when compared to paleolithic artifacts.[2]
Possible examples include several purported prominent ancient artifacts, such as the Venus of Berekhat Ram and the Venus of Tan-Tan. These are thought by many in the archaeological community to be geofacts. A site which shows an abundance of what are likely geofacts is the Gulf of Cambay.
Geofacts can be distinguished from lithic debitage, through experiments and comparisons.[3] Separating geofacts from artifacts is a challenge that archaeologists can face while excavating a site.
