  abstract  = {The present study concerened with taxonomy and palaeoecology of the Cenomanian-Turonian macrobenthic fauna which includes bivalves, gastropods, echinoids, and coral. In addtion, cephalopods are also taken in consideration. 144 taxa are identified and systematically described. Palaeoecological and taphonomic anylsis of the statistically sampled macrobenthos are also discussed. The biostratigraphic sequences along the Cenomanian-Turonian rocks were carried out on the basis of ammonites and other macrobenthic fauna such as corals and bivalves. In order to reconstruct benthic association, 41 statistically sampled were subjected to cluster ananlysis by using Past Programm (Hammer et al., 2001). 10 association and three assemblages were described in order to reconstruct the different depositional enviroments.},

  abstract  = {The aim of this study was to assess distribution patterns of articulate brachiopods during the Mesozoic. Exploratory and confirmatory multivariate analyses in this study evaluate whether environmental preferences of brachiopods and bivalves are substantially distinct and whether structure of their communities significantly differ. Specifically, the hypothesis being tested is that differential abundances of Mesozoic brachiopods and bivalves are not related to varying substrate properties only, but also to varying food supply, turbidity and oxygen levels. This hypothesis was evaluated with quantitative data gathered in various field areas and time intervals. They include the Upper Triassic deposits of the West Carpathians and Eastern Alps, the Lower and Middle Jurassic deposits of Morocco, the Middle and Upper Jurassic deposits of the West Carpathians, the Upper Jurassic deposits of the Franconian and Swabian Alb, and the Upper Jurassic deposits of the Swiss Jura. The main conclusion is that brachiopod-dominated communities are characterized by a unique guild structure, with dominance of trophic groups with low metabolic requirements or adapted to nutrient-poor or oxygen-poor conditions. For example, brachiopod co-occured more commonly with epifaunal than with infaunal bivalves in soft-bottom environments. Abundances of brachiopods correlate mostly negatively with increasing proportions of terrigenous admixture (i.e., with increasing amount of land-derived nutrient supply and turbidity).},

  abstract  = {The Upper Cretaceous Ajlun Group (Cenomanian-Turonian) of southern/south-eastern Jordan has been analysed in 15 detailed sections with thicknesses between 40 m and 200 m. Taxonomic, palaeoecological, taphonomic, and sedimentological aspects were taken into account. During the early Upper Cretaceous the study area was situated at the south-eastern margin of the Tethys Ocean, between the palaeo-shoreline in the south-east and an offshore carbonate platform in the west. Thus, the measured sections include a complete facies succession from terrestrial-dominated environments via marginal marine siliciclastics to an area of carbonate precipitation. So far, very little is known about the fauna and the depositional environment of the group, especially of the transitional marginal marine part. Also, in depth studies of the Cretaceous fauna of southern Jordan are very rare. Therefore, the benthic fauna of the area is described in an extensive taxonomic chapter. It consists of 117 taxa, 77 of which are bivalves, 22 gastropods, 9 echinoids, and 4 corals. The phyla Porifera, Bryozoa, and Brachiopoda are represented by 1 species each. Additionally, at least two species of decapod crustaceans were found. One bivalve species is new: Anthonya jordanica from Cenomanian claystones of the eastern study area. 41 quantitative samples of the benthic invertebrate fauna were grouped into nine associations and three assemblages by means of a Q-mode cluster analysis. These are described as remnants of former communities and their environments are discussed. Salinity and substrate consistency are assumed to have been the most important environmental parameters controlling the faunal distribution. The overall palaeo-environment is discussed on the basis of sedimentological and palaeoecological results. It was primarily influenced by the morphology of the sea floor, sediment supply, and salinity of the sea water.},

  abstract  = {Previous work on Jurassic bivalves from the Iberian Range is reviewed, whereby emphasis is placed on Callovian-Kimmeridgian species. The taxonomy, distribution pattern and ecology of the bivalve fauna occurring in Middle and Upper Jurassic rocks of the Aragonian Branch of the Iberian Range have been analysed. For this purpose 14 sections and 5 additional outcrops, selected according to the abundance of bivalves, were measured in detail and sampled. The rocks studied belong to the Chelva, Y{\´a}tova, Sot de Chera and Loriguilla formations of Callovian-Kimmeridgian age. The distribution of species of bivalves is given for each section. More than 3000 specimens of bivalves representing 83 species that belong to 46 genera and subgenera of the subclasses Palaeotaxodonta, Pteriomorphia, Isofilibranchia. Palaeoheterodonta, Heterodonta and Anomaldesmata have been used for the taxonomic analysis. One species is new: Plagiostoma fuersichi from the Callovian of the Chelva Fm. The autecology (trophic group and life habit) of each bivalve has been discussed. 49 samples of four sections habe been selected for a quantitative palaeoecological analysis of the bivalve fraction of the benthic fauna. Five bivalve associations and two assemblages are recognised by a Q-mode hierarchical cluster analysis (Ward method). The main environmental factors controlling bivalve associations are thought to be substrate, water energy and distribution of organic matter. The bivalves exhibit a distinct spatial and temporal distribution pattern within the Aragonian Branch. Four of the bivalve associations occur in the Upper Oxfordian (Sot de Chera Fm) and one association in the Lower Callovian (Chelva Fm). In the Sot de Chera and Loriguilla formations, the abundance of bivalves decreases from NW to SE i.e., from relatively close to the shore line towards the distal-most part of the carbonate platform. In the Chelva Fm. bivalves are abundant in the Ari{\~n}o region, interpreted as a palaeogeographic high. The distribution of bivalves might have been largely controlled by the availability of nutrients.},
