Beside these two pipids, numerous isolated bones have also been referred to anurans within the site, but never referred to any known less inclusive taxa. Here we describe several identified cranial and postcranial bones referable to Pipidae or its stem-group, which together constitute Pipimorpha. Among these elements, three cranial elements are referred to two unnamed pipimorphs. One of these has gondwanomorph affinities (pipids+South American and African extinct pipimorphs). These conclusions are supported by our phylogenetic analyses. Numerous postcranial elements are not referable to any of the four pipimorph taxa identified at In Becetèn, although some ilia might be tentatively referred to ?<em>Pachycentrata</em> sp. The presence of at least four distinct anuran taxa makes In Becetèn the most diverse anuran site in Mesozoic Africa. It is also the first site in the Mesozoic where four pipimorph taxa are identified. The dominance of pipimorphs in the anuran diversity of the site suggests that In Becetèn was likely more lacustrine than previously thought.</div></div>","PeriodicalId":50780,"journal":{"name":"Annales de Paleontologie","volume":"111 2","pages":"Article 102751"},"PeriodicalIF":1.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143746857","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}

Here, we describe the first and sole record of the aptychus type lower jaw of ammonoid <em>Lamellaptychus lamellosus</em> (Parkinson, 1811) from the Tethyan Himalaya. The aptychus was collected from the Demul section, representing the succession of Upper member of the Spiti Shale Formation. It is discovered from a micaceous silty clay horizon with bivalves (<em>Inoceramus</em>), serpulids, gastropods, ?brachiopods, crinoid ossicles, belemnites and ammonites. The age-diagnostic ammonites, ?<em>Streblites</em> (Oppeliidae) and cf. <em>Aulacosphinctes</em> sp. (Himalayitidae), suggest a Late Tithonian (Ponti–Microcanthum zones) age for the aptychus. The para-species <em>L. lamellosus</em> is recorded for the first time and attributed to oppeliid, though in-situ material is required for a conclusive result. Given the latest advances in the aptychus study, the previous Indian records are re-evaluated. The results suggest that <em>L. kachhensis</em> (Trauth, 1938) from Kachchh Basin is a para-subspecies of <em>L. sparsilamellosus</em> (Gümbel, 1861) rather than a valid para-species of <em>Lamellaptychus</em> genus.

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.).
