 In prehistoric art, finger flutings are lines that fingers leave on a soft surface. Considered a form of cave painting, they occur in caves throughout southern Australia, New Guinea, and southwestern Europe, and were presumably made over a considerable time-span including some are all of the upper Paleolithic. Most are not obvious figures or symbols but, rather, appear to many observers as enigmatic lines. They are also called traces digitose or finger tracings and though these terms are also in part interpretative meanders, macarote, and serpentines. The term finger fluting was coined by Robert Bednarick. Generally they are made in a substance called moon milk. Sometimes they are made through a thin clay film into moon milk underneath or perhaps just into clay. As Henri Breit has published, finger flutings have been recognized since the early days of the 20th century in Europe as Paleolithic. Their recognition as having a similar antiquity outside of Europe lay chiefly in the hands of Sander Dali Xander Gallus and then in Coulodac cave in Australia. Many other sites both in Europe and Australia have been found, some of the more famous being Gargis and Baumeilat Rene caves in France and the cave of Altamira in Spain.
