The growth of a well-dated stalagmite from Barbados records high infiltration rates into the karst aquifer and hence increased rainfall intensity between 6.7 and 3 ka BP in agreement with records from Lake Miragoane, Haiti [Hodell et al., 1991. Reconstruction of the Caribbean climate change over the past 10,500 years. Nature 352, 790–793], mainly reflecting the insolation maximum of the Norther...

Non-marine Oligocene ostracods from Tremembé Formation (Taubaté Basin, Southeast Brazil) are studied for the first time. The study reveals rich assemblages which are probably composed of many new taxa, two of which are described here. The sixteen ostracod species registered are classified in the generaCypretta Vávra, Strandesia Stuhlmann,Potamocypris Brady, Heterocypris Claus,Eucypris Vávra, He...

Diagenesis is a double-edged sword of geochemical recordings. It makes us always doubt about the representativeness many indicators, especially isotope and mineral related. also provides window to explore biogeochemical processes at water–rock interface, which are related interactions between hydrosphere, biosphere, lithosphere. In this study, we identified microbial early diagenesis in lacustr...

this study is focused on the biostratigraphy, sedimentary environments, facies distribution, and sequence stratigraphy of the coniacian–santonian sediments of tange-bulfaris section. five assemblage zones have been recognized by distribution of the foraminifera in the study area. assemblage zone 1(chara ostracods zone) is coniacian in age and occurs in the lower part of the succession. assembla...

Pentastomids (tongue worms) are worm-like arthropods known today from ∼140 species [1]. All but four are parasitic on vertebrates. Their life cycle typically involves larval development in an intermediate host followed by maturation in the respiratory tract of a definitive terrestrial host. Fossil pentastomids are exceedingly rare and are known only from isolated juveniles [2-6]. The identity o...

a fauna of 16 species and genera of marine ostracoda is described and illustrated for the first timefrom the mid-cretaceous of the badamouyeh mountain in kerman province. the ostracod assemblagesuggests a favorable condition during the deposition of the strata. the ostracods can also be used for thecorrelation of cenomanian age formations in many places in the middle east

Stratigraphically significant compression floras have been found in lower Conemaugh ironstone beds and lower Conemaugh dark argillaceous shales in the 7-11 Mine, Columbiana County, Ohio. The known fauna associated with the ironstone beds is limited to branchiopods, myriapods, and a single arachnid. The dark argillaceous shales yielded both invertebrate and vertebrate fossils including freshwate...

Late Miocene "Lake Pannon" (~11.3 Ma) was a remnant of the Central Paratethyan Sea. Successive freshening and constantly changing environmental conditions, like oxygenation, nutrition and substrate led to a well-documented radiation in molluscs and ostracods. Among ostracods (small crustaceans), Cyprideis is one of the most common genera in "Lake Pannon", as well as in several other ancient lak...

In the present study, we test the relevance of a number of environmental factors on alpha and beta ostracod diversities, at species and family level. Ostracods were sampled from several substrates, including sediment and root systems of various floating aquatic macrophytes, from 48 environments (both lentic and lotic habitats, ranging from the river itself, over connecting channels linking with...
