Examination of Jurassic decapod crustaceans associated with microbialite-siliceous sponge biostromes in Gura Dobrogei, eastern Romania, has yielded a unique association of these organisms. Goniodromites aliquantulus new species appears to have inhabited layered sponge biostrome settings only, whereas Cycloprosopon dobrogea and Goniodromites spp. appear to have inhabited a variety of microbialit...

Searching one of the most important reservoirs Cretaceous in Iraq is aim many researchers. The studied sequences are Mishrif Formation southern Iraq. goal to define fauna and design biostratigraphic zoning. Forty genus species were identified as associated with capable reservoir facies (the biostrome). Identification biostrome mainly was Late Cenomanian part studying sequences. Suggested biozon...

The Middle Member of the Lower Cambrian Deep Spring Formation at Mount Dunfee, Nevada contains a diverse assemblage of stromatolites that formed on a tideand storm-dominated, siliciclastic-influenced, carbonate shelf. The stromatolites formed in a shallow subtidal environment within and near active oolite shoals under strongly focused currents. The stromatolites occur in four different lithofac...

Abstract The Hagen-Balve Reef Complex of the northern Rhenish Massif, Germany, is one best examples for globally widespread Givetian to Frasnian reefs. At its eastern end, in Hönne Valley, it reaches up 1000 metres thickness. In general, there limited knowledge concerning faunas and palaeoecology initial reef phases. A unique section at Binolen exposes sharp boundary between underlying, silicic...
