No trace of human presence has been found/ recorded while various paleontological remains have been identified, mainly bones of cave bears, which date back about 10,000 years old. This species lived in Europe during the Pleistocene epoch and later became extinct. It is estimated that the average weight for the male animals was 400-500 kg while the females weighed 200-250 kg. Their (standing) height reached more than 2.5 meters in an upright position! The fossils are found almost exclusively in caves, indicating that it probably spent a longer period of time, in contrast to the brown bear which used the caves only during hibernation.
