| Summary: | The Crassostrea coquina bed on Qeshm Island is named for its high abundance of Crassostrea virginica fossils. Field surveys and photographic documentation from two key locations show that there are three lithostratigraphic units deposited in deltaic or estuarine environments. Morphological changes in the oyster community suggest an upward increase in sediment load and depositional rate. Evidence of mechanical abrasion and erosion on disarticulated oyster shells indicates accumulation by strong storm and flood or tsunami currents. A Plio-Pleistocene age is confirmed through comparison with identified taxa (Crassostrea virginica, Pecten vasselii, Pecten jacobaeus?, Chlamys varia, Placuna placenta, and Conus sp.) and the surrounding Aghajari Formation. The outcrops of the Crassostrea coquina bed in Qeshm Island could be considered as new geosites in the Qeshm International Geopark. Coquina beds hold significant geotourism potential due to their unique bioclastic composition, fossil-rich layers, and paleoenvironmental insights. Their aesthetic appeal and educational value attract both scientific and general visitors, offering opportunities for geoheritage interpretation. Sustainable management, including controlled access and taphonomic monitoring, is essential to preserve these fragile geological archives.
