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.
