Besides the type-locality, it was also recorded from the upper Maastrichtian Tarbur Formation of Iran, from Afghanistan and Tibet. A rich but moderately preserved material is analyzed herein, evidencing the presence of two discrete species: P. anadyomenea and P. acuta n. sp. The new species is characterized by its thallus morphology displaying tapering, keeled segment margins. Besides the morphology, both are also distinguished by biometric parameters such as the outer diameter (D), inner diameter (d), and the d/D ratio. All other Lower Cretaceous species of Pseudocymopolia as well as the Maastrichtian P. anadyomenea have rounded segment margins. Both taxa from the Tarbur Formation occur in inner platform quiet water depositional settings whereas the Lower Cretaceous representatives typically characterize platform margin deposits.","PeriodicalId":55273,"journal":{"name":"Carnets De Geologie","volume":"38 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2019-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79223646","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 mid-Cretaceous Pinda Group of the Congo basin in the northern Angolan offshore is a transgressive supersequence.

Both facies were strongly diagenetically altered, mostly by dolomitic replacement and leaching. Contrary to opinions expressed by other authors that both styles of alteration are early diagenetic phenomena, there is substantial evidence for a burial origin with dolomitic replacement and leaching of calcite having started at depths not less than 150 m and 400 m, respectively.","PeriodicalId":55273,"journal":{"name":"Carnets De Geologie","volume":"1 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2019-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75488414","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}

From 1983 to 1989, the study of this zoological group was the aim of the RCP-CNRS No 728 whose data of the expeditions are the purpose of this ebook: the results concern five species occurring in the Upper Bathyal, i.e., Novocrania anomala, Gryphus vitreus, Terebratulina retusa, Megathiris detruncata, Platidia anomioides and Mergerlia truncata. They are developped over nine chapters, the latter two on the notebooks of samples in the surveyed stations and their distributional charts, as well as those of the five brachiopod species. The occurrences in Mediterranean biocoenoses have revealed biases with the systematics when restricted to shell characters because phylogenetic methods are needed in living species. Another highlight raises questions about the validity of some related fossil species, Terebratula minor (= Gryphus vitreus) is taken as example herein. Finally, the infestation of G. vitreus shells by the Ostreobium alga led to discuss again about the lower limit of the benthic phytal system and its bathymetric variations as far as in the Bathyal.","PeriodicalId":55273,"journal":{"name":"Carnets De Geologie","volume":"1 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2018-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47961254","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}
