ZooMS identified ivory provenance in fragmented prehistoric remains

What the study found: ZooMS, a proteomics method that identifies proteins, successfully identified all ivory samples from La Beleña as African elephant (Loxodonta) and corrected several earlier misidentifications. The study also found that morphology alone was often unreliable for highly fragmented remains.
Why the authors say this matters: The authors conclude that current ivory identification and provenance protocols should be revised, and that open-access reference databases should be expanded. The study suggests that biomolecular methods, especially proteomics, offer a more reliable way to trace prehistoric exchange networks and understand the cultural significance of ivory.
What the researchers tested: The researchers carried out a multidisciplinary analysis of 119 osseous and ivory fragments from the necropolis of La Beleña in Córdoba, Spain, dated to the second half of the 4th to the beginning of the 3rd millennium BC. They combined macroscopic and microscopic study with ZooMS, FTIR (Fourier Transform Infrared Spectroscopy), and ancient DNA extraction.
What worked and what didn't: Traditional morphological criteria had major limits in this fragmented assemblage. FTIR had limited ability to distinguish ivory from bone or to separate elephantid species, and ancient DNA did not yield enough endogenous material for analysis. ZooMS was the method that successfully identified the ivory samples.
What to keep in mind: The abstract does not provide detailed limitations beyond the poor performance of some methods and the failure of ancient DNA. The findings are based on one necropolis case study and on the materials described in the abstract.

Key points

• ZooMS identified all ivory samples as African elephant (Loxodonta).
• Several previous identifications were corrected by ZooMS.
• FTIR could not reliably distinguish ivory from bone or separate elephantid species.
• Ancient DNA extraction did not produce enough endogenous material for analysis.
• The study analyzed 119 osseous and ivory fragments from La Beleña, Córdoba.
