‘Ghost’ fossils of early coccolithophores point to a Triassic diversification of marine calcifying organisms [PDF]

open access: yesNature Communications
Over geologic time, biocalcification – the process by which marine organisms make calcium carbonate (CaCO3) – has reshaped climates, ocean life, and seawater chemistry.

Environmental and physiological conditions that led to the rise of calcifying nannoplankton in the Late Triassic

open access: yesFrontiers in Earth Science, 2023
The rise of calcifying nannoplankton in the Late Triassic (237–201 Ma) had profound consequences for the carbonate buffering capacity of the ocean.

Updating a Paleogene magnetobiochronological time scale through graphical integration [PDF]

open access: yesMethodsX, 2021
All studies focused on the evaluation of paleoecological variability over geological time must be linked to a specific age or time interval, which can be defined using different time scales (biostratigraphic, chronostratigraphic, geochronological or ...

The colonization of the oceans by calcifying pelagic algae [PDF]

open access: yesBiogeosciences, 2019
The rise of calcareous nannoplankton in Mesozoic oceans has deeply impacted ocean chemistry and contributed to shaping modern oceans. Nevertheless, the calcareous nannoplankton colonization of past marine environments remains poorly understood.
