There is presently a very complete inventory list of Pliocene gastropods from Algeria, with 16 species from the Zanclean Tahria Formation and 54 species from the Piacenzian Slama Formation, some of which are recorded for the first time from the Pliocene of the Mediterranean. The northwestern Algeria gastropods represent a shallow-water, fully marine fauna, sandy substrate, and show a typical Upper Pliocene Mediterranean assemblage. The gastropod shells show significant taphonomic alteration; most specimens are abraded and decalcified to a variable degree. Fragmentation was mainly a result of mechanical and biological processes. Bioerosion traces are uncommon, but when they are present, they are predominantly those of predatory gastropods (<em>Oichnus simplex</em> and <em>Oichnus paraboloides</em>), polychaete activity (<em>Maeandropolydora</em> isp.), and acrothoracican barnacle borings (<em>Rogerella</em> isp.). Integration of taphonomical, palaeoecological, and sedimentological characteristics of the gastropod-bearing beds suggests sedimentological concentrations originated from discontinuous processes of winnowing and bypassing sediments, most likely due to storm action in the shoreface depositional environment.</div></div>","PeriodicalId":50780,"journal":{"name":"Annales de Paleontologie","volume":"111 1","pages":"Article 102752"},"PeriodicalIF":1.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143095973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because of its suture line and juvenile shell morphology, <em>Ammonites flexisulcatus</em> belongs to the family Desmoceratidae, and is herein assigned to the upper Aptian genus <em>Caseyella</em> Cantú-Chapa. Our palaeobiological study documents a morpho-dimensional dimorphism based on small-sized, robust, ribbed microconchs with a short ventral rostrum, and large, high-whorled macroconchs with a simple aperture.
