摘要

对塔斯曼海东北部IODP U1511B孔古新世沉积物中的深水凝集有孔虫(DWAF)进行了研究。恢复的有孔虫显示出特殊的三维保存:它们相对不受沉积物成岩作用和压实作用的影响。我们检测了从U1511B-45R到-47R的27个样品，发现了70多种DWAF。该组合完全由最初描述自喀尔巴阡山脉、高加索山脉、特立尼达和西特提斯的 - œcosmopolitanâ -”形式组成，这意味着世界海洋中的矮人动物群之间没有省域性。

The Paleocene of IODP Site U1511, Tasman Sea: A lagerstatte deposit for deep-water agglutinated foraminifera

Deep-water agglutinated Foraminifera (DWAF) are investigated from Paleocene sediments recovered from IODP Hole U1511B in the northeastern Tasman Sea. The recovered foraminifera display exceptional three-dimensional preservation: they are relatively unaltered by sediment diagenesis and compaction.We examined 27 samples fromCores U1511B-45R to -47R, and recovered over 70 species of DWAF. The assemblage consists entirely of â€œcosmopolitanâ€ forms originally described from the Carpathians, Caucasus, Trinidad, and the western Tethys, implying that there is no provinciality among DWAF faunas in the world ocean.

期刊介绍： The Journal of Micropalaeontology (JM) is an established international journal covering all aspects of microfossils and their application to both applied studies and basic research. In particular we welcome submissions relating to microfossils and their application to palaeoceanography, palaeoclimatology, palaeobiology, evolution, taxonomy, environmental change and molecular phylogeny. Owned by The Micropalaeontological Society, the scope of the journal is broad, demonstrating the application of microfossils to solving broad geoscience issues.
