Paleoecological investigation of mammoth remains from the Kraków Spadzista Street (B) site

The paleoecological analysis of over 11,000 mammoth remains from Kraków Spadzista Street (B) site  (24–23 ka BP) has demonstrated that over 50% of them show destructive changes (osteoporosis, osteofibrosis, articular diseases and others). Similar lesions have been revealed on bones of Siberian and European mammoths, and also on North American mastodons. The extinction of the North-Eurasian megafauna is supposed to be connected with changes of the geochemical landscapes at the end of Pleistocene.
