An integrated study including magnetostratigraphy, larger benthic foraminifera and calcareous nannofossil biostratigraphy is presented herein. This work was performed in shallow marine siliciclastics rich foraminifera, around the Ypresian/Lutetian boundary Ésera valley (South-Central Pyrenees). Although content studied interval low, not allowing a precise Y/L to be recognised, taxa found are en...

Evidence of increasing concentrations of dissolved carbon dioxide, especially in the surface ocean and its associated impacts on calcifying organisms, is accumulating. Among these organisms, benthic and planktonic foraminifera are responsible for a large amount of the globally precipitated calcium carbonate. Hence, their response to an acidifying ocean may have important consequences for future...

A thorough review of literature showed that very little work has been carried out on foraminifera from the Muthupet Lagoon. The most notable research in this aspect has been the recent findings by Rajeshwara Rao et al. (2013), who provided an insight into the ecology of one particular species, Asterorotalia trispinosa (Thalmann, 1933). Infaunal habitat preferences of benthic foraminifera, howev...

The distributional patterns of benthic foraminifera provide key information for paleoclimatic, paleoecologic, and paleoceanographic studies. Yet the dispersal mechanisms that provide a crucial link between local populations and large-scale biogeographic patterns are not well documented. We experimentally demonstrate the dispersal of propagules, which include both sexually and asexually produced...

this research is focused on facies distribution, palaeoecology and palaeoenvironment of the gurimember of the mishan formation in kuh-e shur and kuh-e kurdeh sections at the lar area, fars province.the guri member is composed of limestone, marly limestone and marl and the thickness at kuh-e shur andkuh-e kurdeh is about 72 and 110 meters, respectively. based on petrographical studies of 120 thi...

[Dr. Fontanier’s comment] The paper entitled “Variation in stable carbon and oxygen isotopes of individual benthic foraminifera: tracers for quantifying the vital effect” by Ishimura San et al. deals with the applicability of inter-individual delta13C and delta18O distributions (Standard Deviation within species) to reconstruct the bottom water isotopic signatures. This work is based on live an...

A study of the paleoenvironmental evolution middle Eocene platforms recognized in westernmost Tethys has been carried out well-exposed succession from Sierra Espuña-Mula basin (Betic Cordillera, S Spain). Eight microfacies (Mf1 to Mf8) have recognized, based mainly on fossil assemblages (principally larger benthic foraminifera), and rock texture fabric. The fossiliferous assemblage can be assig...
