Responses of a shallow-water ecosystem to the early Paleogene greenhouse environmental conditions : evolution of Larger Foraminifera and coral communities from the Northern Tethys
… – Early Eocene coral occurrences from the Tethys, the Atlantic, the Caribbean realms suggested that these corals types, even if not forming extensive reefs, are common in the biofacies as small isolated colonies, piles of rubble or small patch-reefs. These corals might have developed …

The evolution and palaeobiogeography of mesozoic planktonic foraminifera
… This origination in the centre of Western Tethys was followed by a rapid expansion of planktonic foraminifera throughout Peri-Tethys. This expansion is dominated by the genera Conoglobigerina and Globuligerina and while some believe that their separation is straightforward (based on …

Milankovitch-driven cyclicity and climate controlled dolomitization of a Late Triassic carbonate platform, Hungary
… platform at the southwestern end of the Triassic Tethys now occurs in a single fault-bounded terrain. The Hungarian platform is made up of meter-scale, precessional (~20 k.y.) carbonate cycles. It contains a lower unit, the Main Dolomite Formation (600-1500m thick), which is totally dolomitized. …

Palaeoecology and taxonomy of the macrobenthic fauna from the Upper Cretaceous Ajlun Group, southern Jordan
… 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 …
