Geissenklösterle Flutes are the instruments that archaeologists from the University of Tübingen unearthed in Geissenklösterle (Geißenklösterle) Cave in Southern Germany. Geissenklösterle is an archaeological site that is important for the central European Upper Paleolithic. Archaeologists explored the cave in 1963. It contains traces of early prehistoric art from 43,000 to 30,000 years ago.
Among the most important items are flutes of bird bone and mammoth ivory. The results of radiocarbon dating for animal bones showed that they are from 42,000 to 43,000 years ago. So, Geissenklösterle flutes are among the oldest musical instruments of the prehistoric period.
