This late Eocene global distribution indicates that important dispersal events took place during the middle Eocene (Lutetian), a globally undersampled time interval that is well documented in the Togolese phosphate series. We report here the first discovery of a partial cetacean cranium from middle Eocene deposits of Togo (West Africa). A 3D model of the cranium and teeth was reconstructed in order to reveal hidden anatomical features. The dental and cranial characteristics of the Togolese specimen recall those of protocetid taxa described in Africa, Asia, and North America, but also display significant differences. In particular, we show that the new specimen shares a number of morphological features with the Togolese taxon Togocetus. Such a hypothesis is further supported by a cladistic analysis including 45 taxa and 167 morphological characters, which recovers the new specimen close to Togocetus as the first offshoot of protocetids. Phylogenetic analysis including all the protocetids remains of Kpogamé confirms the singular diversity of the Togolese phosphate basin, and enables to examine potential connections with faunas from contemporaneous localities in Africa.</div>","PeriodicalId":50780,"journal":{"name":"Annales de Paleontologie","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.annpal.2021.102488","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91763716","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}

The present paper aims to update the systematics of two vetigastropod species: Obornella cf. granulata (Sowerby, 1818) and Ambercyclus ornatus (Sowerby, 1819) recently found in the upper Bajocian succession of the Ksour Mountains (Tniet el Klakh Formation) at western Saharan Atlas (northern Algeria). The new Ambercyclus material found in well-preserved conditions confirms the absence of umbilicus in Ambercyclus; thus, we emend the original generic diagnosis.

On the one hand, Globochelus lennieri n. g., n. sp., from the basal Kimmeridgian Baylei biozone is the oldest plesiochelyid species named from the Upper Jurassic, that we dedicate to Lennier, in tribute to his works about geology and fossils from Le Havre. On the other hand, Tropidemys langii, from the Cymodoce biozone, is a form from the European Kimmeridgian whose presence in the Normandy region was doubted. The stratigraphic series of Le Havre, from Lennier and recent works, the sedimentology of the fossiliferous layers and the petrography of the calcareous matrix are examined, showing a littoral platform environment. The Le Havre fossil turtle record including destroyed species is reconsidered: notably the Lower Kimmeridgian plesiochelyid Plesiochelys dollfusii (Lennier), this species being clearly distinctive in the genus, and the early Cretaceous « Palaeochelys » novemcostatus Valenciennes, attibuted to a pre-employed genus but which is here confirmed as a Chelonioidea as, perhaps, “Pelobatochelys sp?”.
