Our new paper provides high-resolution data into the seasonality of prehistoric shellfish exploitation at the Haua Fteah (northern Cyrenaica, Libya). The research applies laser-induced breakdown spectroscopy (LIBS) to analyse Mg/Ca ratios in Patella caerulea Linnaeus 1758 shells recovered from the Haua Fteah by past human populations.
Our new paper provides high-resolution data into the seasonality of prehistoric shellfish exploitation at the Haua Fteah (northern Cyrenaica, Libya).

Our new study delivers the most extensive calibration to date of Patella caerulea (the Mediterranean limpet) as a recorder of sea surface temperatures (SSTs) across the Central and Eastern Mediterranean. The study combined laser-induced breakdown spectroscopy (LIBS) for measuring Mg/Ca ratios with isotope ratio mass spectrometry (IRMS) to analyse oxygen isotope values (δ18O). By analysing 131 modern shells from 22 sites, we explored the relationship between magnesium-to-calcium (Mg/Ca) ratios and oxygen isotope values as palaeotemperature proxies.
