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 ...

Engineering the Cambrian explosion: the earliest bioturbators as ecosystem engineers [PDF]
, 2017 By applying modern biological criteria to trace fossil types and assessing burrow morphology, complexity, depth, potential burrow function and the likelihood of bioirrigation, we assign ecosystem engineering impact (EEI) values to the key ichnotaxa in ...
