Just out @ Lethaia Calcareous nannofossil biostratigraphy: historical background and application in Cenozoic chronostratigraphy Author(s) Claudia Agnini, Simonetta Monechi, Isabella Raffi Abstract: Calcareous nannofossils are considered one of the most powerful biostratigraphical tool in marine carbonate sediments especially in open ocean settings. Their origination goes at least as far back as the Triassic (ca. 220 Ma) when they first biomineralized and produced calcite skeletons. Since then, they have evolved rapidly showing

Just out @ Palaeontology Non-traditional isotope perspectives in vertebrate palaeobiology Author(s) Jeremy E. Martin, Theo Tacail, Vincent Balter Abstract: The recent development of multi-collector inductively coupled plasma mass spectrometry (MC-ICP-MS) notably in the disciplines of earth sciences, now allows the precise measurement of isotope ratios, even at low concentration. Non-traditional isotope systems, such as alkaline earth (Ca, Mg) and transition (Cu, Fe, Zn) metals are now being measured in a variety

Just out @ Science Advances The timetable of evolution Author(s) Andrew H. Knoll, and Martin A. Nowak Abstract: The integration of fossils, phylogeny, and geochronology has resulted in an increasingly well-resolved timetable of evolution. Life appears to have taken root before the earliest known minimally metamorphosed sedimentary rocks were deposited, but for a billion years or more, evolution played out beneath an essentially anoxic atmosphere. Oxygen concentrations in the atmosphere and

Just out @ Palaeogeography, Palaeoclimatology, Palaeoecology Response of macrobenthic communities to the Toarcian Oceanic Anoxic Event in northeastern Panthalassa (Ya Ha Tinda, Alberta, Canada) Author(s) Rowan C. Martindale, Martin Aberhan Abstract: In the Early Jurassic, the late Pliensbachian through early Toarcian interval exhibits significant environmental perturbations and biotic extinctions. This study documents the macrobenthic community during this interval in a region that has previously received comparatively little study: northeastern Panthalassa. The

Andrew Beard, Andrew M. Bush, Anjali M. Fernandes, Patrick R. Getty, Michael T. Hren Abstract: Two pulses of extinction in the late Frasnian (Late Devonian), the Lower and Upper Kellwasser (LKW and UKW) events, coincided with the deposition of organic-rich strata in many parts of the world, including
