Piltdown man and radiocarbon dating

Although trace-element analyses might generate a more specific signature for the composition of materials at these sites, at present efforts to narrow the roster of potential Piltdown source-localities to particular domestic assemblages has not proven fruitful.

A possible Maltese link was initially noted by Weiner et al (1955) who pointed out Hippopotamus teeth from the John H.

Individuals involved in the excavation, cataloguing, curation, or scientific evaluation of materials served as a pool from which those with link in the Piltdown discoveries could be identified. This is also supported by Weiner et al's (1955) own study of the differential levels of absorption of Uranium in the enamel and cementum of E.597, E.598 and E.620. Any perpetrator of the Piltdown fraud must, therefore, have had access to a substantial sample of E. africanavus teeth, an unlikely circumstance if the specimens had been purchased through an antiquities dealer. A number of the specimens recovered from the Piltdown pit and vicinity are indistinguishable in mineralogical content, coloration, and character from materials derived from several Red Crag and Norwich Crag localities in the United Kingdom. The bulk of these assemblages were known by collectors for decades before the first Piltdown "discovery" and served as a supply pool for Natural History supply houses in London and elsewhere.
