Stable isotope composition of Helix ligata (Müller, 1774) from Late Pleistocene-Holocene archaeological record from Grotta della Serratura
Carbon and oxygen isotope ratios were measured in fossil and recent shells of the land snail Helix ligata. Fossil shells were recovered from the archaeological excavations of Grotta della Serratura and recent specimens collected adjacent to the cave. The record is discontinuous and spans from ca 14...
