The abundance of 13c in marine organic matter and isotopic fractionation in the global biogeochemical cycle of carbon during the past 800 ma
TLDR
For the later Neoproterozoic, from 800 to 543 Ma (346 analyses), from the Cambrian through the Jurassic (1616 analyses), and from the Cretaceous and Cenozoic (2493 analyses) the abundance of 13 C in marine organic matter has been compiled as discussed by the authors.About:

TL;DR: In this article, a total of 2128 calcitic and phosphatic shells, mainly brachiopods with some conodonts and belemnites, were measured for their δ 18 O, δ 13 C and 87 Sr / 86 S values.

TL;DR: The geological, geochemical, and biological processes that contributed to the rise of the dinoflagellates, coccolithophores, and diatoms all contain plastids derived from an ancestral red alga by secondary symbiosis are examined.

CO2 CONCENTRATING MECHANISMS IN ALGAE: Mechanisms, Environmental Modulation, and Evolution
TL;DR: In this article, the authors discuss the diversity of CCMs, their evolutionary origins, and the role of the environment in CCM modulation, and a multitude of environmental factors can exert regulatory effects on the expression of the CCM components.

Proterozoic ocean chemistry and evolution: A bioinorganic bridge?
Ariel D. Anbar,Andrew H. Knoll +1 more
TL;DR: Recent data imply that for much of the Proterozoic Eon, Earth's oceans were moderately oxic at the surface and sulfidic at depth, and biologically important trace metals would have been scarce in most marine environments.

A Neoproterozoic Snowball Earth
TL;DR: Negative carbon isotope anomalies in carbonate rocks bracketing Neoproterozoic glacial deposits in Namibia, combined with estimates of thermal subsidence history, suggest that biological productivity in the surface ocean collapsed for millions of years.

Geocarb III: A Revised Model of Atmospheric CO2 over Phanerozoic Time
TL;DR: In this article, the GEOCARB model has been updated with an emphasis on factors affecting CO2 uptake by continental weathering, including the role of plants in chemical weathering and the application of GCMs to study the long-term carbon cycle.
