... in dead/fossil assemblages. Among other things, this will allow verification in sediment cores of the putative recent introduction in European coastal areas of T6, which is often considered an exotic species originating from East Asia. The first step consisted of the amplification of a fragment of 1000...

... of the benthic foraminiferal faunas and the reappearance of different faunal assemblages in the newly formed environments resulting from ecosystem recovery. Recolonization by benthic foraminifera has been reported after anoxic events ( Coccioni and Galeotti, 1994 ; Coccioni and others, 1995 ; Speijer...

.... The age of the Lower Marrat Member ( Figure 3 ) is interpreted as Late Sinemurian–Early Toarcian based on the following evidence. The top of the Lower Marrat Member is Early Toarcian based on the common recovery of Nannoceratopsis triceras ( Al-Sahlan, 2005 ). Strontium-isotope analyses from the Lower...

.... The Gippsland inner shelf biofacies (0–50 m depths) consists of medium to coarse quartz-rich sands and bioclastic silty sand. Abundant living, relict and recently dead miliolids occur in the inner shelf with rare planktonic forms. Common planktonic foraminifera, with Cibicides, Parrellina, Elphidium...

... foraminifera can give information on the type of ecological niches occupied. Planktonic foraminiferal depth habitats are derived from a δ 13 C and δ 18 O ranking of individual species ( Norris and Wilson, 1998 ; Huber and others, 1999 ), analogies with modern counterparts and paleo-ecological evidence...

... gastropods have exclusively tightly coiled initial whorls. Most protoconchs were formed by planktonic larvae, and this is the first documentation of a supraspecific trend in Paleozoic invertebrate larvae. Open coiling makes shells weak and vulnerable to attack and force. The replacement of weak-shelled...

This is the first example in planktonic foraminifera where the morphological variability in a morphospecies exceeds its...

... evidence from benthic foraminifera suggests less extensive polar ice sheets during the Kaena Subchron interval ( Shackleton et al . 1995 ), which together with a wide range of fossil data, probably indicate a warmer climate. Thus, the dominantly cool temperature signature of the planktonic foraminifera...

.... In recent years, there has been a growing appreciation that planktonic foraminifer shells from the geological record of deep-sea carbonate oozes and chalks are frequently recrystallized on a micrometer scale. The recrystallization tends to reduce (but not eliminate) the oxygen and carbon isotope differences...
