This short report describes my participation in the Third International Conference of Archaeological Science in the Eastern Mediterranean and Middle East at the Cyprus Institute in Nicosia, Cyprus during the week of March 14-19, 2022. I presented my paper entitled ‘Stowaway: A Ship Rat’s Journey’ on Tuesday, 15/3 in the session Mediterranean palaeomobility: written sources, material networks and skeletal data, chaired by Prof. Cyprian Broodbank and Dr. Efthymia Nikita. My presentation covered the work done thus far on the study of the ship rats excavated from the early Islamic period shipwreck Ma‘agan Mikhael B (MMB). First, I shared the archaeological and historical context of the shipwreck, then discussed the faunal remains recovered from the site, highlighting the rarity of this level of organic material preservation in the marine environment – especially of micro mammal remains. Second, I shared our research questions regarding ascribing geographic provenance to the ship rats, and described the comparative geometric morphometric (GMM) study we devised to see if this was possible. Third, I shared the preliminary results of our study which suggest that the GMM method was effective in finding differences between geographic groups in the comparative sample, and that the MMB ship rats appear to have come from the southern Levant and the central Mediterranean. My talk generated a nice discussion, and Prof. Broodbank had some insightful suggestions for the continuation of our study. I also received a lot of positive feedback from the audience members, as the ship rats are truly such a unique find and unusual proxy for connectivity in the antique Mediterranean.
