“…3). Such predominance of Tethyan ammonites is well-corresponding with scarce stable isotope data derived from belemnite rostra (Price & Rogov 2009, Wierzbowski et al 2013, showing the warming event during the mid-late Kimmeridgian at the studied area. This episode was also recognized in other Boreal regions, i.e.…”

“…Li et al (2013) also did not observe any significant correlation between these two values, neither in belemnite populations nor in single specimens. Differences in the correlation of d 18 O bel and Mg/Ca between different belemnite species indicate a presumably species-specific incorporation of trace elements, with species of Hibolithes showing no co-variation of the two values (McArthur et al 2004;Wierzbowski & Joachimski 2009;Wierzbowski et al 2013). These results cast doubt on the straightforward interpretation of elemental data in terms of absolute temperature.…”

The late Kimmeridgian Nusplingen Plattenkalk (palaeolatitude ~30°N) is one of the well‐known European Plattenkalk konservatlagerstätten. The laminated limestones of this lagerstätte have been deposited in a shallow lagoon, surrounded by sponge‐microbial mounds, some of which formed small islands. Plattenkalk sediments are often thought to have been deposited below a halocline, which was induced by high evaporation rates. By measuring the stable isotope composition of belemnite rostra (n = 27) of the species Hibolithes semisulcatus, the depositional environment of the Nusplingen Plattenkalk has been investigated. Cathodoluminescence‐microscopy and trace element analysis have been applied to check for diagenetic alteration of the studied rostra. The mean δ13C of the well‐preserved rostra is +0.03 ± 0.27‰, the mean δ18O −0.68 ± 0.3‰. A narrow range of stable isotope data acquired from an accumulation of rostra, regurgitated by a fish or reptile, supports the notion that belemnite calcite reflects environmental conditions. The palaeontological and sedimentological findings suggest that H. semisulcatus was autochthonous to the Nusplingen Plattenkalk. Anoxic conditions prevailed in the sediments and temporarily in the water‐column above the sediment/bottom water interface. A nektobenthic life style can be excluded for the Nusplingen belemnites; a demersal life style seems unlikely. Comparison with δ18Obel data from other latitudes indicates that a latitudinal gradient played a role in the δ18O composition of seawater. A pelagic, inner shelf setting is therefore suggested for the Plattenkalk, an interpretation that is supported by palaeontological evidence. It is here proposed that the formation of the Nusplingen Plattenkalk was not caused by salinity stratification. It is further suggested that the belemnites were not restricted to deep‐water settings, but also occurred in shallow waters and higher in the water‐column.
