Abstract
The fragmentary condition of the Krapina Neandertal remains has been offered as one line of evidence for the hypothesis that these hominids were the victims of cannibals seeking marrow and brains. Two other hypotheses regarding the causes of the framentation have been raised: 1) a substantial portion of the breakage in the Krapina collection is attributable to excavation damage; and 2) the rest of the breakage is attributable to sedimentary pressure and to natural rock falls that occurred during the site's prehistory. The purpose of this paper is report on tests of these three hypotheses concerning the cause of breakage in the Krapina material. Microscopic inspection of all Krapina hominid specimens showed that 23% of the material was inadvertantly broken during excavation or during quarrying that took place at the end of the last century. The morphology of the prehistoric breakage is inconsistent with the cannibalism hypothesis and supports the hypothesis that prehistoric breakage was caused by sedimentary pressure and/or roof falls.
