The presence of this species indicates warmer water conditions than currently exist in the areas where it is found. The dating of these deposits is crucial for understanding past sea-level changes and interglacial periods. The U-series nuclides method, specifically Th/U dating, has been used to date Strombus bubonius shells. However, single dates obtained from mollusk shells using this method can be unreliable due to the mobility of uranium isotopes. Despite this, a statistical approach has been demonstrated to yield coherent chronologies in both continental and marine environments. Studies in the Almeria area of southeastern Spain, using Th and U isotope measurements on Strombus bubonius fossils, have yielded a coherent chronology. These results indicate that Strombus bubonius was present in the Mediterranean basin at the end of the Mindel-Riss interglacial (Oxygen Isotope Stage 7) and during each high sea-level episode of the Riss-Würm interglacial (Oxygen Isotope Stage 5). Almeria, Spain: Research in the Almeria area has provided significant data on the presence and dating of Strombus bubonius. The findings support the presence of the species during specific interglacial periods. Other Locations: Persististrombus latus has been found in various locations in Spain, including the Balearic Islands (Mallorca), and the Canary Islands (Fuerteventura, Lanzarote, Tenerife, Gran Canaria)  Paleoclimate: The species serves as an indicator of past warm-water conditions. Sea-level changes: The dating of the deposits helps to reconstruct past sea-level fluctuations. Stratigraphy: The presence of Strombus bubonius necessitates a reconsideration of Tyrrhenian stratigraphy
