This section exposes Paleocene to lower Eocene shales and marls of the El Haria Formation. The uppermost Paleocene part of the Sidi Nasseur section is marked by poor to moderately rich, but fairly diversified nannofossil associations, containing the typical latest Paleocene taxa of the top of NP9a. The ostracode record displays an almost continuous record in the uppermost Paleocene part of the section. Representatives of <i>Aegyptiana, Paracosta, Reticulina</i> and <i>Reymenticosta</i> make up the major part of the ostracode fauna. The benthic foraminiferal assemblage consists of numerous small calcareous benthic foraminifera, like <i>Anomalinoides midwayensis</i> and <i>Lenticulina</i> spp. and many large <i>Frondicularia phosphatica, Pyramidulina</i> spp. These, together with the non-calcareous agglutinated foraminifera and the rare planktic foraminifera, indicate an inner neritic to coastal environment with eutrophic conditions, regularly interrupted by oxygen deficiency. The dominance of non-calcareous benthic foraminifera between intervals with abundant calcareous benthic foraminifera suggests post-mortem dissolution. The foraminiferal d<sup>13</sup>C record (based upon <i>Pyramidulina latejugata</i>) of the latest Paleocene in the Sidi Nasseur area is very similar to these from coeval sediments at Gebel Duwi and Gebel Aweina in Egypt. Oxygen isotopic ratios indicate a marine setting with a water composition affected by evaporation. During the latest Paleocene, the highly productive shallow water environment evolved to shallower water depths with higher salinity and increasing dominance of <i>A. midwayensis</i>.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Reconstruction of a latest Paleocene shallow-marine eutrophic paleoenvironment at Sidi Nasseur (Central Tunisia) based on foraminifera, ostracoda, calcareous nannofossils and stable isotopes (delta<sup>13</sup>C delta<sup>18</sup>O)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-22 01:31:43.759337","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Stratigraphy; Benthic foraminifera; Ostracoda; Calcareous nannofossils;Inner neritic; Coastal; Stable isotopes","OtherDescriptors":null,"Notes":null,"AnaPub":2009,"MonPub":null,"DateUpdate":"2015-02-26","DateCreate":"2012-11-12","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000263906300006","VABBcode":null,"OpenAcc":1,"DOI":"10.1344/105.000000273"},"refs":null,"anarec":{"AnaID":219927,"PubliDate":2009,"Pagination":"93-112","XtraPublOfAnaID":null,"ISBN":null,"Volume":"7","Issue":"1-2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":212753,"SerRR":"Geologica Acta.
