Fossil Foraminifera appear in the Early Cambrian, at about the same time as the first skeletonized metazoans. However, due to the inadequate preservation of early unilocular (single-chambered) foraminiferal tests and difficulties in their identification, the evolution of early foraminifers is poorly understood. By using molecular data from a wide range of extant naked and testate unilocular spe...

Factors influencing the composition of shallow water benthic foraminifera along the SW coast of South Africa at two locations (Table Bay, TB; St Helena Bay, SHB) ∼200km from each other were examined. Small taxa dominated in both locations; living assemblages from SHB (28 species, Ammonia parkinsoniana dominant) differed from TB (34 species, Elphidium articulatum dominant). Environmental paramet...

Large benthic foraminifera are unicellular calcifying reef organisms that can form symbiotic relationships with a range of different microalgae. However, the cellular functions, such as symbiosis and calcification, and other aspects of cellular physiology in large benthic foraminifera are not fully understood. Amphisorus kudakajimensis was used as a model to determine the detailed cellular char...

Recent observations have identified increased mass loss from Greenland marine-terminating outlet glaciers (MTOG) with implications for global sea-level rise and wider ocean circulation. The flow of Atlantic-sourced waters to the margin is thought be a major control on MTOG behaviour. Investigation longer-term records role MOTG dynamics are needed improve understanding potential future trends in...

Abstract. The international ice core community has a target to obtain continuous cores stretching back as far 1.5 Myr. This would provide vital data (including CO2 profile) allowing us assess ideas about the cause of Mid-Pleistocene Transition (MPT). European Beyond EPICA project and Australian Million Year Ice Core each plan drill such in region known Little Dome C. Dating will be challenging,...

During ROPME Winter Cruise 2006, twenty six surface sediment samples taken from the Northwestern part of the Persian Gulf at depths of 13-77m were analyzed for their foraminifera content. A total of 93 species of benthic foraminifera were found in the study area. The foraminifera assemblages were dominated by Ammonia beccarii, Spiroloculina excavata, S. depressa, Quinqueloculina dimidiata,...

Earth experienced warm temperatures during the Pliocene followed by a substantial cooling that culminated in an ice age climate at beginning of Pleistocene. This warmth had significant impact on global environments and ocean circulation. The collision Indian Eurasian plates further amplified this climatic pattern. southern Ocean was severely impacted these changes circulation pattern Plio-Pleis...
