The 535 m high Istállós-kő Cave (Hungarian Istállós-kői-barlang) in the Bükk Mountains, in Heves County, (Northern Hungary) contained finds of stone tools and bone spear points from the Aurignacia of the Paleolithic. At 958.1 m, the Istállós-kő is the second highest peak in the Bükk Mountains.
The lower layer of the cave contained about 50 spearheads made of bone with a split base, which are part of the Aurignac points. The upper, subarctic layer reaches an age of around 31,000 years, which has been corroborated by radiocarbon dating. This layer contains spearheads of a different type, not having a split but a massive base. Such bone tips are called Lautscher tips. The three-by-four-meter stone-lined hearth contained not only charcoal but also numerous animal bones, 80% of which were those of young cave bears. Based on the penis bones found, there were around 2000 animals. A special feature is an approximately 45,000 year old, 12 cm long bone flute.
