Short summary
The mollusc Arctica islandica can survive for hundreds of years, and its annual growth captures environmental conditions, each shell providing a detailed climatic record.  Dating is essential for sample selection, but radiocarbon and cross-dating are laborious and costly.  Alternatively, amino acid geochronology was investigated in the three aragonitic layers of the shells. This study confirms the value of AAG in the iOSL layer as a method for range-finder dating Quaternary A. islandica shells.
