article_snippet.sent: a bone chewed by a hyena with teeth marks was discovered on 18 July 1995 in Slovenia .
article_snippet.sent: Dr Diedrich said analysis of the bone shows the holes are teeth marks, and the shape is just the result of the bone not breaking when the bone was chewed.
article_snippet.sent: Hyenas left bones in repeating similar tooth mark and crush damage stages, demonstrating a butchering/bone cracking strategy.
article_snippet.sent: Hyenas produced round-oval puncture marks in cub femora only by the bone-crushing premolar teeth of both upper and lower jaw.
article_snippet.sent: Dr Diedrich derides all the research that has gone into these bones so far.
article_snippet.sent: Dr Diedrich also points out that there is no evidence on these bones that tools have been used to make the holes, further cementing the idea tools were made by hyena teeth.
article_snippet.sent: ‘The “cave bear cub femora with holes” are, in all cases, neither instruments nor human made at all,’ Dr Diedrich concludes.
article_snippet.sent: Hyenas left, therefore, “pseudo-bone flutes” during the Late Middle to Late Pleistocene all over Europe in cave bear dens, and on different cave bear species/subspecies.
