The narrow-nosed rhinoceros survived until around 40 kya in southern Europe. The last records in Italy date to around 41,000 years ago., while remains dating to 40,000 years ago are knowns from Bacho Kiro cave in Bulgaria.

The ratios of skeletal elements implies that only the parts of the body with the most meat were carried to the site. The profile of ages of rhino bones in the cave resembles natural mortality curves, suggesting that there was not selective hunting, and the fact that marks of other carnivores are rare implies that the carcasses were acquired by active scavenging or opportunistic hunting.
