Based on an analysis of 19 mummified Maori heads (mokomokai) referred to our forensic laboratory for anthropological analysis prior to their official repatriation from France to New Zealand, and data from the anthropological and medical literature, we propose a complete forensic procedure for the analysis of such pieces. A list of 12 original morphological criteria was developed. Items included the sex, age at death, destruction of the skull base, the presence of argil deposits in the inner part of the skull, nostrils closed with exogenous material, sewing of eyelids and lips, pierced earlobes, ante-mortem and/or post-mortem tattoos, the presence of vegetal fibers within nasal cavities, and other pathological or anthropological anomalies. These criteria were tested for all 19 mokomokai repatriated to New Zealand by the French authorities. Further complementary analyses were limited to fiberscopic examination of the intracranial cavities because of the taboo on any sampling requested by the Maori authorities. In the context of global repatriation of human artifacts to native communities, this type of anthropological expertise is increasingly frequently requested of forensic anthropologists and other practitioners. We discuss the reasons for and against repatriating non-authentic artifacts to such communities and the role played by forensic anthropologists during the authentication process.
