...Atsushi Ando; Brian T. Huber Abstract Rotalipora greenhornensis has long been considered a representative planktonic foraminiferal species of the single-keeled Rotaliporinae of late Cenomanian age. Its taxonomic identity, however, is still ambiguous because this taxon has been distinguished...

Schematic stratigraphic column for Cenomanian-Turonian interval of Arobes section. A: Profile of δ13C values (versus Peedee belemnite standard, PDB) for carbonate sediment and brachiopod shells. B: Concentration of C0–C2 dibenzothiophenes (logarithmic scale). TOC—total organic carbon; sed.—sediment. C: Concentration of total 2,3,6-trimethylarylisoprenoids (logarithmic scale). D: Occurrence of planktonic foraminifers (dashed lines indicate beds with no planktonic foraminifer). Gray zone indicates proposed stratigraphic range of oceanic anoxic event 2 (OAE2) based on δ13C excursion (Kuypers et al., 2002). Solid horizontal lines show last occurrence (LO) of Rotalipora greenhornensis and R. cushmani (spp.—species). Numerical ages of LO of R. greenhornensis, LO of R. cushmani, and first occurrence (FO) of Quadrum gartneri are from Keller and Pardo (2004), Hardenbol et al. (1998), and Erba et al. (1995), respectively. Overall analytical reproducibility of δ13C in this study is estimated to be 0.05‰ or better. Overall uncertainties of δ13C are within 0.2‰.

Correlation of Cenomanian–Coniacian δ13C events between England and Italy. The English Chalk reference curve in black is an unsmoothed composite plotted against age; see Figure 12, Table 3 and text for details. High-resolution profiles from Gubbio are plotted against stratigraphic height for Contessa Quarry (Stoll & Schrag, 2000, medium grey curve, left) and the Gubbio S2 core from Vispi Quarry, Contessa Gorge (Tsikos et al. 2004, dark grey curve, right). The S2 curve has been offset by + 0.25 ‰ δ13C relative to the Contessa data to facilitate comparison. Gubbio biostratigraphy after Premoli Silva & Sliter (1995), derived from the Bottaccione section, transposed to Contessa Quarry using stratigraphic heights relative to the Livello Bonarelli, with additional data from Tsikos et al.(2004). ‘Late Turonian Events’ represent the succession of isotope events defining the long-term positive δ13C excursion in the Upper Turonian, with the Bridgewick and Navigation negative excursions defining the bottom and top of the interval and the Hitch Wood Event representing the carbon-isotope maximum.
