Although the proximate extinction mechanisms are disputed, there is widespread agreement that a major extinction pulse occurred immediately below the biostratigraphically defined Permian–Triassic boundary. Our statistical analyses of stratigraphic confidence intervals do not comply with a single end-Permian extinction pulse of ammonoids in Iran. High turnover rates and extinction pulses are observed over the last 700 k.y. of the Permian period in two widely separated sections representative of a larger area. Analyses of body sizes and morphological complexity support a gradual decline over the same interval. Similar pre–mass extinction declines and disturbances of the carbon cycle have sometimes been reported from other regions, suggesting a widespread, but often overlooked, environmental deterioration at a global scale, well before the traditional main extinction pulse.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380011144482723204","@type":"Researcher","foaf:name":[{"@value":"Wolfgang Kiessling"}],"jpcoar:affiliationName":[{"@value":"1GeoZentrum Nordbayern, Department of Geography and Geosciences, Universität Erlangen−Nürnberg, Loewenichstraße 28, 91054 Erlangen, Germany"}]},{"@id":"https://cir.nii.ac.jp/crid/1380011144482723200","@type":"Researcher","foaf:name":[{"@value":"Martin Schobben"}],"jpcoar:affiliationName":[{"@value":"2Museum für Naturkunde, Leibniz Institute for Evolution and Biodiversity Science, Berlin, Invalidenstraße 43, 10115 Berlin, Germany"},{"@value":"3School of Earth and Environment, University of Leeds, Woodhouse Lane, Leeds LS2 9JT, UK"}]},{"@id":"https://cir.nii.ac.jp/crid/1380011144482723203","@type":"Researcher","foaf:name":[{"@value":"Abbas Ghaderi"}],"jpcoar:affiliationName":[{"@value":"4Department of Geology, Faculty of Science, Ferdowsi University of Mashhad, Azadi Square, 9177948974 Mashhad, Iran"}]},{"@id":"https://cir.nii.ac.jp/crid/1380011144482723205","@type":"Researcher","foaf:name":[{"@value":"Vachik Hairapetian"}],"jpcoar:affiliationName":[{"@value":"5Department of Geology, Isfahan (Khorasgan) Branch, Islamic Azad University, PO Box 81595-158, Isfahan, Iran"}]},{"@id":"https://cir.nii.ac.jp/crid/1380011144482723201","@type":"Researcher","foaf:name":[{"@value":"Lucyna Leda"}],"jpcoar:affiliationName":[{"@value":"2Museum für Naturkunde, Leibniz Institute for Evolution and Biodiversity Science, Berlin, Invalidenstraße 43, 10115 Berlin, Germany"}]},{"@id":"https://cir.nii.ac.jp/crid/1380011144482723202","@type":"Researcher","foaf:name":[{"@value":"Dieter Korn"}],"jpcoar:affiliationName":[{"@value":"2Museum für Naturkunde, Leibniz Institute for Evolution and Biodiversity Science, Berlin, Invalidenstraße 43, 10115 Berlin, Germany"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"00917613"}],"prism:publicationName":[{"@value":"Geology"}],"dc:publisher":[{"@value":"Geological Society of America"}],"prism:publicationDate":"2018-01-24","prism:volume":"46","prism:number":"3","prism:startingPage":"283","prism:endingPage":"286"},"reviewed":"false","url":[{"@id":"https://pubs.geoscienceworld.org/gsa/geology/article-pdf/46/3/283/6259094/283.pdf"}],"createdAt":"2018-01-24","modifiedAt":"2024-02-20","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/2051996266973442048","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Enhanced flux of extraterrestrial 3He across the Permian : Triassic boundary"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1130/g39866.1"},{"@type":"CROSSREF","@value":"10.1186/s40645-019-0267-0_references_DOI_SgCUeh6rXHJLsAyjlL44fkWKSOg"}]}
