Hydrodynamic transport and differential exposure to environmental conditions are the primary factors contributing to shell deposition. A total of 58 mollusk species were identified, including 30 bivalves and 28 gastropods. The Veneridae was the most prominent, with the highest number of species (7) and shells comprising 64.22 % of the total. Key species contributing to the accumulation include the bivalves Anomalocardia cf. <i>flex?uosa, Polymesoda </i>cf.<i> arctata, Leukoma pectorina, Tivela mactroides, Crassostrea rhizophorae</i>, and the gastropod <i>Vitta virginea</i>. These species are primarily characteristic of estuarine environments, with the exception of <i>T. mactroides</i>. Notably, the first recorded occurrence of the non-native gastropod <i>Naria turdus</i> (Cypraeidae) on the Colombian Caribbean coast was documented. The accumulations exhibit varying degrees of abrasion, fragmentation, encrustation, and bioerosion, with some shells appearing almost intact, indicating differences in origin and transport mechanisms. The extraction of shells for ornamental purposes poses a significant challenge to this natural accumulation.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Shell-bearing Bivalvia and Gastropoda from a rocky shore in the Central Caribbean of Colombia","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-29 01:33:07.348940","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Magdalena river, Punta Roca, calcareous platform, Mollusca, Veneridae, introduced species","OtherDescriptors":null,"Notes":null,"AnaPub":2024,"MonPub":null,"DateUpdate":"2024-11-06","DateCreate":"2024-11-06","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.marpolbul.2024.117045"},"refs":null,"anarec":{"AnaID":396523,"PubliDate":2024,"Pagination":"117045","XtraPublOfAnaID":null,"ISBN":null,"Volume":"208","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43520,"SerRR":"Marine Pollution Bulletin.
