“…D. rugatum occur in the Saxo-Bohemian Cretaceous Basin mainly in two facies reflecting deposition in different environments. While the nautilids inhabited hemipelagic environments (recorded by limestones) in NW Bohemia (Teplice Formation, Hudcov Limestone - Wiese et al 2004) and Saxony (Strehlen and Weinböhla limestones), the other records are from the Jizera Formation indicating shallower water conditions with larger siliciclastic input (Uličný 2001). However, the bathymetric conditions in the two areas may not have been very different.…”

“…rugatum became extinct shortly after its appearance (at the top of the Hudcov limestone in the BCB) in the Late Turonian. Strong predation pressure cannot be excluded as a potential reason as Ekrt et al (2001) and Wiese et al (2004) reported the highest vertebrate diversity in the lithounit Xb α (at the base). Marine reptiles and larger fishes (Ekrt et al 2008), especially chondrichthyans (sharks and rays, 19 species), occurred , including malacophagous taxa, which document a relatively high predation pressure.…”

The endemic Late Cretaceous nautilid genus Deltocymatoceras Kummel, 1956 is represented by Deltocymatoceras leiotropis (Schlüter, 1876) and D. rugatum (Fritsch & Schlönbach, 1872). Characteristic for this genus is a bulbous involute shell with strong radial ribbing and a ventral keel, which appears in post-juvenile ontogenetic stages. The combination of these morphological features is unique among post-Palaeozoic nautiloids. Both species are restricted to the Late Turonian-Middle Coniacian of Central Europe and England. Until now, the type species D. leiotropis was known based only on the holotype specimen. This specimen is re-described with revised occurrence and for the first time photographically illustrated. The only preserved syntype from the type specimens of D. rugatum was re-discovered during this revision and more than thirty other specimens were studied. Representatives of Deltocymatoceras show clear morphological changes during their ontogeny and acquisition of maturity, most notably the appearance of a ventral keel in premature stages and its disappearance at maturity. The hypothesis of a close phylogenetic affinity of Deltocymatoceras to the genus Cymatoceras Hyatt, 1884 is based on similar morphological features such as the suture, ribbing, shell shape and early ontogenetic development. The ventral keel is quite an exceptional feature of morphology in post-Palaeozoic nautiloids. In particular the combination with an involute depressed shell is only shared with representatives of the genus Angulithes Montfort, 1808 (Cretaceous-Palaeogene) and Gryponautilus Mojsisovic, 1902 (Triassic). The combination with a compressed and evolute planispiral shell is more common in Palaeozoic and some post-Palaeozoic nautiloids. The ventral keel is discussed here in relation to its functional aspects (hydrodynamic stability) in combination with the strong radial ribbing (protection of the shell against mechanical damage). The appearance of the genus concurred with the late Turonian shallowing/cooling associated with the "Hyphantoceras Event" and the availability of an ecologic niche (i.e., absence of medium-sized, keeled ammonites at that time). Low abundance, an endemic occurrence, and the very short stratigraphic range of the genus (~3.5 Ma) reflect the limited evolutionary success of the Deltocymatoceras lineage.• Key words: Nautilida, taxonomy, phylogeny, ontogeny, palaeogeography, functional morphology, biostratigraphy.

Carbon (d 13 C org , d 13 C carb ) and oxygen (d 18 O carb ) isotope records are presented for an expanded Upper Cretaceous (Turonian-Coniacian) hemipelagic succession cored in the central Bohemian Cretaceous Basin, Czech Republic. Geophysical logs, biostratigraphy and stable carbon isotope chemostratigraphy provide a high-resolution stratigraphic framework. The d 13 C carb and d 13 C org profiles are compared, and the time series correlated with published coeval marine and non-marine isotope records from Europe, North America and Japan. All previously named Turonian carbon isotope events are identified and correlated at high-resolution between multiple sections, in different facies, basins and continents. The viability of using both carbonate and organic matter carbon isotope chemostratigraphy for improved stratigraphic resolution, for placing stage boundaries, and for intercontinental correlation is demonstrated, but anchoring the time series using biostratigraphic data is essential. An Early to Middle Turonian thermal maximum followed by a synchronous episode of stepped cooling throughout Europe during the Middle to Late Turonian is evidenced by bulk carbonate and brachiopod shell d18 O carb data, and regional changes in the distribution and composition of macrofaunal assemblages. The Late Turonian Cool Phase in Europe was coincident with a period of long-term sea-level fall, with significant water-mass reorganization occurring during the mid-Late Turonian maximum lowstand. Falling D 13 C (d 13 C carb -d 13 C org ) trends coincident with two major cooling pulses, point to pCO 2 drawdown accompanying cooling, but the use of paired carbon isotopes as a high-resolution pCO 2 proxy is compromised in the low-carbonate sediments of the Bohemian Basin study section by diagenetic overprinting of the d 13 C carb record. Carbon isotope chemostratigraphy is confirmed as a powerful tool for testing and refining intercontinental and marine to terrestrial correlations.
