“…The GSSP is marked by the lowest occurrence of the inoceramid Cladoceramus undulatoplicatus (= Platyceramus undulatoplicatus , see discussion in Gale et al ., ; Kennedy et al ., ) at 94·4 m in the Cantera de Margas section. Along with inoceramids (Gallemì et al ., ), the type section exhibits microfossil events (Lamolda & Paul, ; Melinte & Lamolda, ; Peryt & Lamolda, ) and a negative 0·3‰ excursion in δ 13 C carb (Lamolda & Paul, , ) that, together, have provided the basis for correlation with sites elsewhere (e.g. Jenkyns et al ., ; Jarvis et al ., ; Gale et al ., ; Takashima et al ., ; Voigt et al ., ; Sprovieri et al ., ; Wendler, ).…”

A 101 m thick stratigraphically complete late Coniacian-early Santonian (ca 89 to 83 Ma) sedimentary sequence drilled in Tanzania (Tanzania Drilling Project Site 39) allows, for the first time, examination of the planktonic foraminiferal biostratigraphy and evolution, the depositional history, and geochemical patterns of the subtropical-tropical Indian Ocean region. The sedimentary succession corresponds to an outer shelf to upper slope setting and is dominated by calcareous clayey siltstones and mudstones. The occurrences of Tethyan marker species enable application of the tropical biozonation including identification of the Dicarinella concavata and Dicarinella asymetrica Zones. In addition, Tanzania Drilling Project Site 39 is proposed as reference section for the Coniacian/Santonian boundary in the Indian Ocean with the boundary placed at the lowest occurrence of Globotruncana linneiana in agreement with the Global Stratotype Section and Point (Spain). The record at Tanzania Drilling Project Site 39 provides a unique opportunity to document the planktonic foraminiferal evolution in a subtropical marginal sea environment during a key period in their evolutionary history characterized by a major radiation among the deep-dwelling taxa. Combined documentation of lithological and geochemical changes (%CaCO 3 , %C org , d 13 C carb and d 18 O carb ) reveals a setting influenced by continental-derived nutrients in the Dicarinella concavata Zone (Lindi Formation) with a change to higher carbonate production and reduced surface water primary productivity in the overlying Dicarinella asymetrica Zone (Nangurukuru Formation). Planktonic foraminiferal assemblage changes mirror the depositional and geochemical trends and indicate a progressive shift from a more eutrophic to a more oligotrophic regime through time. At the local scale, this palaeoceanographic scenario is consistent with the deepening of coastal Tanzania in response to the Late Cretaceous marine transgression registered in south-east Tanzania. Because the tectonic evolution and sea-level rise along the East Africa continental margin is superimposed on the Coniacian-Campanian global long-term sea-level high, this study hypothesizes that 252

Surgah Formation at Male-kuh well section with 82 meters thickness has been studied at Pole -Dokhtar area. Surgah Formation at mentioned section was composed of limestone and shaly limestone. The lower and upper contacts of studied formation with Sarvak and Ilam formations are conformed. Based planktonic foraminifera study 37 species belonging to 10 genera in frame of two planktonic foraminiferal biozones were identified respectively as below: 1) Dicarinella concavata Interval Zone; 2) Dicarinella asymetrica Total Range Zone. Finally, based on recent investigation have been detected middle Turonian-Late Santonian age for studied section. According to (Robaszynski and Caron 1979), the first occurrence of Dicarinella primitiva has been shown base of the Coniacian stage. The first occurrence of Di. primitiva was placed under the Turonian-Coniacian boundary. Robaszynski and Caron 1995 recorded the first occurrence of Dicarinella primitiva and Dicarinella concavata were simultaneous and assigned to late Turonian which correlated with ammonite's species Subprionocyclus neptuni. In the correlation between ammonite and Dicarinella primitiva at Tethyan realm first occurrence of Di. primitiva was close to the Middle-Late Turonian sub stage. The base of Coniacian stage was identified based on the FODs of Archaeoglobigerina cretacea and Dicarinella concavata from planktonic foraminifera with FOD of Cremnoceramus walterdorfensis walterdorfensis from inoceramid group, while the base of Santonian stage recorded using LOD of Dicarinella primitiva, Whiteinellids group with FODs of Dicarinella asymetrica and Inoceramus aff. vistulensis (inoceramid species).
