Due to the insufficient nature of the paleontological record, the “Sparnacian” succession of the Paris and Dieppe-Hampshire basins still needs to be robustly chronostratigraphically correlated with other Paleogene records worldwide. In order to refine the stratigraphy of the Thanetian-Lower Ypresian succession in northern France a number of cores and outcrop sections have been investigated palynologically. As a result, an updated version of the dinoflagellate cyst zonation for the Paris and Dieppe basins is proposed and contains six new or revised biozones for this stratigraphical interval: <i>Alisocysta margarita</i>, <i>Apectodinium hyperacanthum</i>, <i>Apectodinium</i>-acme, <i>Biconidinium longissimum</i>-acme, <i>Dracodinium astra</i>, and <i>Axiodinium lunare</i>/<i>Stenodinium meckelfeldense</i>. Based on combined bio-, litho- and chemostratigraphic data, it appears that the dinocyst assemblages, corresponding to the PETM event interval (“Sparnacian” deposits, Soissonnais and upper Mortemer formations), are characterized by an acme of <i>Apectodinium</i> spp. (70–98%) in both basins, sometimes alternating with an acme of a few gonyaulacoid groups in the Dieppe Basin. Dinocyst assemblages from the PETM interval contain a significant number of atypical, longer specimens of <i>Apectodinium parvum</i>, which could represent an ecological onshore substitute for <i>Axiodinium augustum</i> in the Paris and Dieppe-Hampshire basins. The establishment of a new <i>Biconidinium longissimum</i>-acme Zone suggests that the stratigraphic hiatus previously inferred within this sequence in the Paris Basin does not exist.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"New insights on the Late Paleocene - Early Eocene dinoflagellate cyst zonation for the Paris and Dieppe basins","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-26 01:32:09.578696","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"dinoflagellate cysts; Late Paleocene; Early Eocene; \"Sparnacian\"; zonation; Paris and Dieppe-Hampshire basins","OtherDescriptors":null,"Notes":null,"AnaPub":2021,"MonPub":null,"DateUpdate":"2022-06-29","DateCreate":"2022-06-28","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000708645900005","VABBcode":null,"OpenAcc":1,"DOI":"10.1051/bsgf/2021035"},"refs":null,"anarec":{"AnaID":353108,"PubliDate":2021,"Pagination":"44","XtraPublOfAnaID":null,"ISBN":null,"Volume":"192","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42477,"SerRR":"Bulletin de la Société Géologique de France.
