Mid-Cretaceous paleoenvironmental changes in the western Tethys [PDF]
Climate of the Past, 2018 We present a continuous record of surface water temperature and fertility variations through the latest Barremian–Cenomanian interval (ca. 27 Myr) based on calcareous nannofossil abundances from the western Tethys.

Toarcian oceanic anoxic event: An assessment of global causes using belemnite C isotope records [PDF]
, 2005 Two hypotheses have been proposed to explain simultaneous large negative excursions (up to 7% PeeDee belemnite) in bulk carbonate (delta(13)C(carb)) and organic carbon isotope records (delta(13)C(org)) from black shales marking the Toarcian oceanic ...
