Hohlenstein-Stadel is a cave located in the Hohlenstein cliff (not to be confused with the Hohle Fels) at the southern rim of the Lonetal (valley of the Lone) in the Swabian Jura in Germany.

The most significant finding was a small ivory statue called the Löwenmensch, which is one of the oldest pieces of figurative art ever found.

[1] The first excavations at Hohlenstein were made in 1861 by Oskar Fraas, geologist and paleontologist, who was searching for cave bear bones at the Bärenhöhle and the Stadel.

[2] More work followed in 1996 and 1997, when a dig led by Nicholas Conard, Michael Bolus and Andrew Kandel was conducted in the valley in front of the caves.

Kind managed to locate the exact spot in which the Lion-man had been discovered and to find numerous additional ivory splinters that were found to fit onto the figurine.

[2][4] In addition to the Lion-man figurine, pendants carved from mammoth ivory and perforated animal teeth dating from the Aurignacian have been uncovered at the cave.

[3] On August 27, 1937, excavators discovered the right femur diaphysis, measuring around 25 cm (10 in) in length, of an archaic hominin in the cave.

This femur represents the only archaic hominin fossil found in a Mousterian context within the entire Swabian Jura region.

Each valley would contain a core area of around 3 to 4 km (1.9 to 2.5 mi) length, surrounded by a buffer zone of a least 100 m (330 ft) width.
