A comparative study of woolly mammoths from the Gravettian site Kraków Spadzista (Poland), based on estimated shoulder heights, demography, and life conditions

Abstract

This article interprets the life conditions of woolly mammoths (Mammuthus primigenius) from the Upper Paleolithic archaeological site Kraków Spadzista in Poland. We propose that the mammoths’ irregular mortality profile (also known as age profile) was shaped over several decades by major death events, which serially depleted the youngest cohorts. Taphonomic data and comparisons with other Eurasian archaeological and nonarchaeological sites provide context for hypothesizing that the mammoth-bone assemblage was accumulated at least partly through opportunistic human hunting of the most vulnerable animals in mixed herds. Humans exploited heightened mammoth vulnerability during climatic stress periods, killing and butchering most of the animals, although some mammoths in the assemblage may have died from natural causes. The evidence for environmental stress affecting the mammoths includes paleoecological data about local climatic conditions, the abundant signs of mammoth-bone abnormalities in the assemblage, the relatively smaller size of adult female mammoths compared with those from the similarly dated archaeological site Milovice I (Czech Republic), and the unusually high proportion of juvenile mammoths in the assemblage.

“…The author has taken the 'manus height' as 100% and determined the percentages of each bone contribution for different proboscidean taxa. This approach allowed Larramendi (2016) and many others (e.g., Haynes, 2017;Haynes et al, 2018) to use fragmentary skeletal elements (i.e., not associated elements) for the large mammals body size calculation based on a scapula length (scapula-related shoulder height), humerus length (humerus-related shoulder height) or another bone.…”
