In the final analysis, what are we to make of the fractured bones of Pikermi? Any clear answer to that question shall have to wait until such time as the final analysis is made. And it remains doubtful whether any totally “final” analysis ever can be made. Ambiguity is inherent in the enterprise. Surely, we cannot yet conclude, on the basis of the available reports, that humans were not responsible for the breakage observed on
Another thing to keep in mind is that some modern researchers believe that in general evidence for human breaking of bone has been neglected or gone unrecognized. Robert J. Blumenschine and Marie M. Selvaggio, anthropologists at Rutgers University, conducted experiments in which they used pieces of sandstone to break African mammal (gazelle, impalla, wildebeest) longbones in order to extract marrow.

2.9 Pierced Shark Teeth from the Red Crag, England (Late Pliocene)
At a meeting of the Royal Anthropological Institute of Great Britain and Ireland, held on April 8, 1872, Edward Charlesworth, a Fellow of the Geological Society, showed many specimens of shark (
The record of the meeting, published in the journal of the Anthropological Institute, informs us: “Mr. Charlesworth pointed out the conditions under which boring molluscs, as
Charlesworth (1873, pp. 91–92) did not personally suggest human agency, but did show a letter from Professor Owen, who had carefully examined the specimens and stated: “the ascription of the perforations to human mechanical agency seemed the most probable explanation of the facts.”
During the ensuing discussion, Mr. Whitaker suggested tooth decay as the cause, noting one specimen with holes in various stages, from slight indentation to perforation (Charlesworth 1873, p. 92). Then Dr. Spencer Cobbold, an expert on parasites, suggested parasites as the agent of perforation but admitted, according to the summary report: “it might be said with truth, perhaps, that no entozoon [internal animal parasite] had hitherto been known to take up its abode in the bones or teeth of fishes” (Charlesworth 1873, p. 92).
