Over a thousand stone tool pieces of the Mousterian culture were found (Gorjanović-Kramberger, 1899; 1906; 1913;). The Quarternary layers in the half-cave at the Hušnjak hill in Krapina stratisgraphically belong to the time of the last Riss - Würm interglacial period, (Malez, 1970 a), - the time period ranging from 130,000 up to 50,000 years before today. The most significant remnants found in Krapina are most definitely the proto-human remains. A total of 876 individual human remains were found - out of which 196 are single teeth, and the others are cranial and postcranial skeletal parts (Radovčić et. al. 1988).
