“…The mean surface temperature from the GCM, around the Kopet-Dagh areas is about 22°C (Valdes and Sellwood 1992). The GCM results also show low precipitation near the Kopet-Dagh Basin (Moore et al 1992). A total annual precipitation of <500 mm calculated for this area is within the arid zone suggested by Hallam (1985Hallam ( , 1993 and Moore et al (1992).…”

Some workers have argued that the mineralogy of ancient carbonates may have been different from that of modem sediments, with calcite being considered the dominant mineral during the Ordovician, Devonian-mid Carboniferous, and JurassicCretaceous to Early/Middle Cenozoic (e.g. Sandberg 1983;Wilkinson and Algeo 1989). Variation in carbonate mineralogy has been related to the position of global sea level (emergent or submergent modes, Wilkinson et al. 1985), change in rates of seafloor spreading (e.g. Mackenzie and Pigott 1981;Hardie 1996), PC0 2 level (e.g. Sandberg 1985Mackenzie and Morse 1992; Hallock 1997) and Mg/Ca ratios related to spreading rate (e.g. Stanley and Hardie 1998). However, other researchers suggest that the assumption of change of original carbonate mineralogy through time needs to be re-evaluated in the light of mineralogical change that is related to water temperature or latitudes (e.g. Nelson 1988). Evaluation of Ordovician (Arenig to Ashgill) Gordon Group carbonates of Tasmania (Australia), based on petrographic (e.g. abundant Chlorozoan biota, and oomold texture) and geochemical criteria (such as high Sr/Na ratios) indicated that aragonite (not calcite) was the predominant mineral in these warm water, subtropical carbonates (Rao 1990). Petrographic (e.g. presence or absence of aragonite relicts, abundant acicular to fibrous isopachous marine cement, presence of diffuse laminae and a number of spalled ooids) and geochemical evidences (such as elevated Sr) in the Upper Jurassic Mozduran limestone, in Kopet-Dagh Basin in northeast Iran, showed variation in carbonate mineralogy, in spite of similar atmospheric PC0 2 level, global sea-level and tectonic setting. This is evidenced by aragonite occurring in the shallowest part of the basin (Adabi and Rao 1991) and mainly calcite with some aragonite forming in the relatively deeper water (below wave base) (Adabi 1997). Carbonate mineralogy in Recent shallow marine carbonates, and in experimental studies, varies with seawater temperature. In the Recent, aragonite is the predominant mineral in warm, shallow marine carbonates and calcite the dominant mineral in marine cool water carbonates (James and Clarke 1997). Therefore,variations in carbonatemineralogy in the Mozduranlimestone are attributedto seawater temperature assuming invariant seawater chemistry prevailed in the Upper Jurassic. Several Jurassic examples show variations in ooid carbonate mineralogy, such as the Upper Jurassic Smackover oolite of the Gulf Coast region (southern Arkansas and northern Louisiana) and Upper Jurassic ooids in the Purbeck limestones of Swiss and French Jura. These results are not in agreement with the concept of a "calcite sea" during the Ordovician and the Upper Jurassic periods. Very recently, Westphal and Munnecke (2003) showed that in spite of the tendency of abiotic precipitates (Sandberg 1983) and skeletal mineralogy (Stanley and Hardie 1999) to follow the general trend of calcite seas and aragonite seas, organisms with calcite and aragonite mineralogy coexis...

“…Therefore, the overlying soil would have been a type of terra rossa, which is typically found on limestones in semi-arid to sub-humid climates. Several authors have proposed an arid to semi-arid Mediterranean climate for the period of the Late Kimmeridgian of Western Europe with strong seasonality (Moore et al 1992;Hallam 1993;Abbink et al 2001). In the absence of a local siliciclastic source and accumulation by alluviation, most of the non-carbonate fraction in soils is derived from aeolian dust (Wright 1994).…”

High-spired nerineoid gastropods are abundant in the tropical Kimmeridgian carbonate deposits of the Swiss Jura Mountains. Understanding the mode of life of this extinct group of gastropods is crucial for palaeoenvironmental reconstructions. The knowledge on their ecology is, however, limited by the near absence of comparable large high-spired gastropods in Recent carbonate systems. Large high-spired turritellid gastropods are, however, abundant in siliciclastic-dominated environments in the tropical Indian Ocean. In order to compare the Recent and fossil environments of these two morphologically similar groups, a Recent tidal Xat, where abundant turritellids occur, was studied in the National Park of Nopparat Thara in the district of Krabi, South Thailand. Ninety specimens of Turritella duplicata were measured and mapped, revealing zonations in population distribution, both parallel and perpendicular to the beach line. Attention was also paid to other faunal elements and sedimentary features. The thusgained information on the depositional environment was then compared to a section of shallow-water carbonate deposits from the Kimmeridgian of the Swiss Jura Mountains. These are characterised by the occurrence of tidal laminites, dinosaur tracks, beach deposits and nerineoid gastropods. Especially for one succession, the faunal composition and sedimentary structures in the fossil record show intriguing similarities to those found today on the Nopparat Thara tidal Xat, indicating that it formed in a comparable setting. It is therefore suggested that for some Kimmeridgian carbonate deposits, the Nopparat Thara tidal Xat, although dominantly siliciclastic, represents an environmental analogue.

“…Moreover, no major climatic changes during the Late Juras− sic are evident from this area and estimated mean land−sur− face temperature based on climate models is around 30°C (Sellwood and Valdes 2006), while sea−surface temperatures range between 20-30°C (Valdes and Sellwood 1992;Moore et al 1992). Reconstructed palaeotemperatures based on ox− ygen isotope data from the Portuguese Upper Jurassic are somewhat lower than these predictions and range between 12-14°C based on belemnites and 15.5-22.5°C based on oysters, which is close to the temperatures calculated from belemnites of Kimmeridgian and Tithonian age from Mal− lorca (14-16°C; Price and Sellwood 1994).…”

The Actinoceramus sulcatus lineage (Parkinson, 1819) (Bivalvia: Inoceramidae) is a very distinctive and abundant component of late Albian (Early Cretaceous) molluscan assemblages that is found throughout Europe, Central Asia, Japan and the Far East of Russia, southern and western North America, South Africa, and possibly India, in a range of shallow- to deep-marine facies. The lineage encompasses a wide and continuous range of morphologies that provide evidence of phyletic evolution at varying rates combined with large ecophenotypic plasticity within populations. The evolution of A. sulcatus marks the oldest appearance of well-developed radial folds and sulci within the Inoceramidae. The range of morphological variation makes formal taxonomic subdivision of the group problematic. Here we use a combination of formal successional subspecies and informal morphotypes to subdivide the lineage into the following taxa: A. sulcatus forma sulcatus, A. sulcatus forma subsulcatus (Wiltshire, 1869), A. sulcatus forma munsoni (Cragin, 1894), and A. sulcatus biometricus Crampton, 1996. Within these taxa and morphotypes, we synonymise a large number of earlier names that have been applied to variants within the lineage. Each of the forms recognized has biostratigraphic utility and we describe four new lineage biozones, in ascending order: A. concentricus parabolicus, A. sulcatus, A. sulcatus forma munsoni, and A. sulcatus biometricus biozones. The lowest occurrence of A. sulcatus is approximately coincident with the base of the upper Albian as currently defined, at least throughout most of Europe, and this datum provides a valuable tool in correlation. The nature of radial folds within the A. sulcatus lineage poses interesting but still unanswered questions regarding shell morphogenesis in bivalves and the functional significance (if any) of radial folds in the Inoceramidae.
