“…Because of the key role of ancient shells and shell fossils in the reconstruction of past climate conditions, they have long been a matter of interest to geological Vernal et al 1992;Geary et al 1992;Goodwin et al 2001;Ullmann et al 2017;Killam & Clapham 2018;Scholz et al 2020;Morán et al 2021), archaeological studies (Quitmyer et al 1997;Leng & Lewis 2016). Indeed, one of the main motivations for the study of bivalves (Müller et al 2017;Huyghe et al 2020;Das et al 2021;Kelemen et al 2021;), gastropods (Cespuglio et al 1999;García-Escárzaga et al 2019;Irie & Suzuki 2020), and extinct species such as belemnites Urey et al 1951;Alberti et al 2021) is to gain insight into climatic conditions.…”

This study aimed to identify suitable mollusk shells for use in sclerochemistry and sclerochronochemistry studies which, applied on shells in archaeological record, can help researchers reconstruct past climatic conditions. The shell features of eight commonly occurring native mollusk species in the Persian Gulf were examined. Four sea snails (Bufonaria echinata (Link, 1807), Tibia fusus (Linnaeus, 1758), Architectonica perspectiva (Linnaeus, 1758), Cypraea turdus winckworthi (F. A. Schilder & M. Schilder, 1938)) and four bivalves (Vepricardium asiaticum (Bruguière, 1789), Callista umbonella (Lamarck, 1818), Saccostrea cucullata (Born, 1778), Anodonta cygnea (Linnaeus, 1758)) were collected from their natural habitat in 2020, for analysis. The study used micro Raman spectroscopy to identify shells with an aragonite outer layer, a requirement for sclerochemistry research. Additionally, the study utilized sclerochronological methods to determine whether the shell samples could be appropriately studied for sclerochronochemistry research. Raman spectroscopy results indicated the presence of aragonite in all species, excluding Saccostrea cucullata. Pigments were also present on the surface of all shells except those of Callista umbonella. Cross-sectional analysis indicated that the shells of Callista umbonella exhibit clear daily, monthly, and annual growth lines with a thickness of 1650 µm in the outer layer, making them excellent candidates for sclerochemistry and sclerochronochemistry studies.
