L’identità nel frammento: riconoscimento del taxon attraverso l’impronta peptidica nel sito antico e medio olocenico di Takarkori (Libia)

Faunal remains in archaeological contexts are often very fragmented. This significantly affects taxonomic identification and thus the understanding of the exploitation of animal resources. The biomolecular method ZooMS (Zooarchaeology by Mass Spectrometry) allows identifying even very small fragments at the genus level, sometimes at the species one, using the “collagen fingerprints". We present the preliminary results of the first application of ZooMS on Takarkori rock shelter (Libya), a key site to reconstruct Early to Middle Holocene (10.200-4600 ka) socio-cultural dynamics in the Sahara. The analysis shows the successful application of the method on archaeological sequences from sheltered sites in hyper-arid environments. It also aims at opening the discussion on the need to develop effective biomolecular research to distinguish wild and domestic species, crucial to understand subsistence strategies.
