Two main models have been put forward: i) catastrophic mass extinction, almost total for some authors, compatible with the geologically instantaneous paleoenvironmental effects of a large meteorite impact (Chicxulub impact, Mexico); and ii) gradual mass extinction, compatible with the paleoenvironmental effects of massive, long-lasting volcanism (Deccan Traps, India). Over the years, a lot of evidence has been proposed supporting one hypothesis or the other, highlighting isotopic (δ18O, δ13C, 87Sr/86Sr) as well as taphonomic, biostratigraphic, quantitative (relative and/or absolute abundance), phylogenetic, and even teratological. We review previous planktic foraminiferal and stable isotope studies, and provide new quantitative and statistical tests from two pelagic sections: the El Kef section (Tunisia), recognized as the most continuous and expanded lowermost Danian section worldwide, and the Sidi Ziane section (Algeria), affected by relevant hiatus in the lower Danian. The results indicate that all the latest Maastrichtian planktic foraminiferal species except those of Guembelitria went extinct exactly at the KPB, supporting the hypothesis of an almost total extinction. In the light of this new evidence, we maintain that the Maastrichtian planktic foraminiferal specimens found worldwide in lower Danian samples could be the result of similar reworking and vertical mixing processes to those at El Kef and Sidi Ziane.","PeriodicalId":48830,"journal":{"name":"Fossil Record","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2022-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48633643","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}

Our finding sheds further light on the paleodiversity of atractocerine beetles, highlighting a peculiar distribution during the Eocene.

A new genus and species of fossil wood wasp is described\u0000and figured from mid-Cretaceous Kachin amber, representing the first\u0000occurrence of the family Xiphydriidae in the fossil record. Paraxiphydria resinata gen. et\u0000sp. nov. exhibits typical apomorphies of the family including a generally\u0000cylindrical body, elongate neck and dome-shaped head. Nonetheless, owing to\u0000a unique combination of traits including features hitherto unknown among\u0000species of the family, the genus is classified within a separate subfamily,\u0000Paraxiphydriinae subfam. nov. A key is presented to the\u0000suprageneric groups of Xiphydriidae. The newly described species is the\u0000first fossil xiphydriid wood wasp, extends the occurrence of Xiphydriidae\u0000into the mid-Cretaceous and adds to the known diversity of features in the\u0000family. Lastly, the simplification of wing venation and hypotheses of\u0000host-plant affiliations of early xiphydriids are discussed. We evaluate\u0000pollen associated with the wasp, assign it to the genus Cycadopites and conclude\u0000that an affiliation to the Cycadales is most likely.

Besen, U. Struck, E. Seibertz","doi":"10.5194/fr-24-395-2021","DOIUrl":"https://doi.org/10.5194/fr-24-395-2021","url":null,"abstract":"Abstract. Albian to Turonian carbonate deposits at three different locations of the\u0000Lower Saxony Cretaceous and thereby of the European mid-Cretaceous epeiric\u0000shelf sea were investigated for their fossil agglutinated foraminiferal\u0000fauna. In this study, 71 samples from two quarries and three drill cores\u0000were treated with formic acid, which enabled the study of agglutinated\u0000foraminiferal assemblages even in highly lithified limestones. In total, 114\u0000species were determined and classified as belonging to nine morphogroups. In\u0000general, four agglutinated foraminiferal assemblages are distinguished: (1) an uppermost Albian–lowermost Cenomanian assemblage from the Wunstorf drill\u0000cores, with the dominant taxa\u0000Bathysiphon spp., Nothia spp., Psammosphaera fusca, Reophax subfusiformis, Bulbobaculites problematicus, Tritaxia tricarinata, Flourensina intermedia, Vialovella frankei, Arenobulimina truncata, and Voloshinoides advenus; (2) a Cenomanian\u0000assemblage from the Baddeckenstedt quarry and Wunstorf drill cores, with\u0000Ammolagena clavata, Tritaxia tricarinata, Vialovella frankei, Arenobulimina truncata, and Voloshinoides advenus; (3) an assemblage related to the Cenomanian–Turonian Boundary Event in\u0000Wunstorf and Söhlde dominated by Bulbobaculites problematicus; and (4) a Turonian assemblage in the\u0000Wunstorf and Söhlde sections with high numbers of Ammolagena contorta, Repmanina charoides, Bulbobaculites problematicus, Gerochammina stanislawi, and\u0000Spiroplectammina navarroana. The latest Albian–earliest Cenomanian assemblage consists of tubular,\u0000globular, and elongate foraminiferal morphogroups which are typical for the\u0000low- to mid-latitude slope biofacies. All other assemblages are composed of\u0000elongate foraminiferal morphogroups with additionally globular forms in the\u0000proximal settings of Baddeckenstedt and Söhlde or flattened planispiral\u0000and streptospiral forms in more distal settings of Wunstorf. For these\u0000assemblages, a new agglutinated foraminiferal biofacies named “mid-latitude\u0000shelf biofacies” is proposed herein. Changes in the relative abundance of\u0000different morphogroups can often be referred to single features of\u0000depositional sequences. Furthermore, classical macro-bioevents, which are\u0000often depositional-related, of the Lower Saxony Cretaceous seem to have a\u0000micro-bioevent or acme equivalent of the agglutinated foraminiferal fauna.\u0000","PeriodicalId":48830,"journal":{"name":"Fossil Record","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2021-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48729759","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}
