Just out @ Paleoceanography Diploastrea heliopora Sr/Ca and δ18O records from northeast Luzon, Philippines: an assessment of inter-species coral proxy calibrations and climate controls of sea surface temperature and salinity Author(s) R. D. Ramos, N. F. Goodkin, F. P. Siringan, K. Hughen Abstract: The Indo-Pacific coral Diploastrea heliopora reveals regional multi-decadal to centennial scale climate variability using coral carbonate δ18O (δ18Oc) as a combined proxy for sea surface temperature (SST)
Just out @ Paleontological Research Taxonomy of Maastrichtian–Thanetian Deep-Sea Ostracodes from U1407, IODP Exp 342, off Newfoundland, Northwestern Atlantic, part 2: Families Eucytheridae, Krithidae, Thaerocytheridae, Trachyleberididae, and Xestoleberididae Author(s) Tatsuhiko Yamaguchi, Hiroki Matsui and Hiroshi Nishi Abstract: Little is known about the taxonomy of Paleocene ostracodes from ocean drilling sites. Herein, we report 14 ostracode species of the families Eucytheridae, Krithidae, Thaerocytheridae, Trachyleberididae, and Xestoleberididae from Cretaceous-Paleocene sediments at U1407 of Integrated
Just out @ Paleontological Research Taxonomy and Stratigraphic Changes of Diatom Resting Spores from DSDP Leg 41, Offshore Northwest African Margin, Based on Nannofossil Biostratigraphy Author(s) Itsuki Suto and Yuichiro Tanaka Abstract: We reinvestigated the standard calcareous nannofossil and diatom biostratigraphy zonations from Deep Sea Drilling Project (DSDP) Leg 41 Holes 366 and 369A in the eastern equatorial Atlantic Ocean in order to determine the geologic ages for the low-latitude
Just out @ Paleoceanography Title: Ventilation history of Nordic Seas overflows during the last (de)glacial period revealed by species-specific benthic foraminiferal 14C dates Author(s) Mohamed M. Ezat, Tine L. Rasmussen, David J. R. Thornalley, Jesper Olsen, Luke C. Skinner, Bärbel Hönisch, Jeroen Groeneveld Abstract: Formation of deep water in the high-latitude North Atlantic is important for the global meridional ocean circulation, and its variability in the past may have played
Just out @ Paleoceanography Title: Meltwater pulse recorded in Last Interglacial mollusk shells from Bermuda Author(s) Ian Z. Winkelstern, Mark P. Rowe, Kyger C. Lohmann, William F. Defliese, Sierra V. Petersen, Aaron W. Brewer Abstract: The warm climate of Bermuda today is modulated by the nearby presence of the Gulf Stream current. However, iceberg scours in the Florida Strait and the presence of ice-rafted debris in Bermuda Rise sediments indicate
The week that just ended was particularly poor in descriptions of new species. The new species reported come from Egypt and China, are only two: a vertebrate (new genera and new species of catfish) and an invertebrate (new species of an insect). Full account of fossil species reported this week: Qarmoutus hitanensis, gen. et sp. nov., a new marine catfish (Siluriformes; Ariidae) from the upper Eocene Birket Qarun Formation, Wadi El-Hitan, Egypt, was reported in PLOS one (1st March 2017). Vitimoilus ovatus sp. nov., a Lower Cretaceous species of Cyrtophyllitinae (Insecta: Ensifera) from the Dabeigou Formation and Yixian Formation, China, was reported in Cretaceous Research (4th March 2017).
Just out @ Revue de Micropaléontologie Title: Early Spathian (Late Olenekian, Early Triassic) Radiolaria from the Bac Thuy Formation, northeastern Vietnam Author(s): Osamu Takahashia, Takumi Maekawab, Toshifumi Komatsub, Phong Nguyen Ducc, Tien Dinh Congc, Hung Doan Dinhd Abstract: This article presents a rather well-preserved radiolarian fauna recovered from black siliceous mudstone occurring in the Ky Cung River section 02 (KC02) of the Bac Thuy Formation, Lang Son Province, northeastern Vietnam.
Just out @ Cretaceous Research Title: Turonian cephalopods (ammonoids and a nautiloid) from the Wadi Daya Formation of the Talerzha Basin (South Riffian Ridges Domain, northern Morocco) Author(s): Mohamed Benzaggagh, Mohamed Oumhamed, Bruno Ferré, Jean-Louis Latil Abstract: The Wadi Daya Formation, or the Calcaires crayeux of the older literature, attains a thickness of 10–40 m in the Talerhza Basin of the South Riffian Ridges. Previously, this unit was first dated as
Just out @ Proceedings of the Royal Society B Title: A behavioural framework for the evolution of feeding in predatory aquatic mammals Author(s): David P. Hocking, Felix G. Marx, Travis Park, Erich M. G. Fitzgerald, Alistair R. Evans Abstract: Extant aquatic mammals are a key component of aquatic ecosystems. Their morphology, ecological role and behaviour are, to a large extent, shaped by their feeding ecology. Nevertheless, the nature of this crucial
Just out @ Proceedings of the Royal Society B Title: Surrogate taxa and fossils as reliable proxies of spatial biodiversity patterns in marine benthic communities Author(s): Carrie L. Tyler, Michał Kowalewski Abstract: Rigorous documentation of spatial heterogeneity (β-diversity) in present-day and preindustrial ecosystems is required to assess how marine communities respond to environmental and anthropogenic drivers. However, the overwhelming majority of contemporary and palaeontological assessments have centred on single higher taxa.
