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

Suttner, Erika Kido, Carlo Corradini, Stanislava Vodrážková, Monica Pondrelli, Luca Simonetto Abstract: The polyphased Kačák Episode near the Eifelian-Givetian boundary (Middle Devonian), well documented globally, resembles other global biotic extinction events driven by climate change. High-resolution conodont biodiversity patterns from shallow marine, slope and

Biskaborn, Larisa Nazarova, Lutz Schirrmeister, Josefine Lenz, Georg Schwamborn, Guido Grosse Abstract: Vast areas of the terrestrial Subarctic and Arctic are underlain by permafrost. Landscape evolution is therefore largely controlled by climate-driven periglacial processes. The response of the frozen ground to late Quaternary warm and

Just out @ PLOS one Highly regulated growth and development of the Ediacara macrofossil Dickinsonia costata Author(s) Scott D. Evans, Mary L. Droser, James G. Gehling Abstract: The Ediacara Biota represents the oldest fossil evidence for the appearance of animals but linking these taxa to specific clades has proved challenging. Dickinsonia is an abundant, apparently bilaterally symmetrical Ediacara fossil with uncertain affinities. We identified and measured key morphological features of over
