Abstract. Smear slide petrography has been a standard technique during scientific ocean drilling expeditions to characterize sediment composition and classify types, but presentation of these percent estimates track downcore trends in become less frequent over the past 2 decades. We compare semi-quantitative smear physical property (natural gamma radiation, NGR) solid-phase geochemical (calcium...

The Middle Eocene Climatic Optimum (MECO; ~40 Ma), which interrupted for ~500–600 kyr the long-term cooling trend culminating at Eocene/Oligocene boundary, still requires a comprehensive understanding of biotic resilience. Here we present high-resolution integrated foraminiferal and calcareous nannofossil study across MECO from expanded continuous Tethyan Baskil section (eastern Turkey) that of...

The Turonian–Coniacian continental fossil record in Europe is scarce. Here we present a new assemblage of early Coniacian age that was systematically collected from the coal-bearing Gosau Group Tiefengraben locality near St. Wolfgang, Austria. diverse composed at least 60 taxa including sporomorphs and Normapolles-related pollen, seeds leaves angiosperms gymnosperms, charophytes, gastropods, bi...

[1] This study analyzes coccolithophore abundance fluctuations (e.g., Emiliania huxleyi, Gephyrocapsa specimens, and Florisphaera profunda) in core MD01‐2444 sediment strata retrieved at the Iberian Margin, northeastern Atlantic Ocean. Coccolithophores are calcareous nannofossils, a major component of the oceanic phytoplankton, which provide information about past ecological and climatological ...
