Platform carbonates are among the most voluminous of Cretaceous deposits. The production of carbonate platforms fluctuated through time. Yet, the reasons for these fluctuations are not well understood, and the underlying mechanisms remain largely unconstrained. Here we document the long-term trend in Cretaceous carbonate platform preservation based on a new data compilation and use a climate-carbon cycle model to explore the drivers of carbonate platform production during the Cretaceous. We show...

Abstract The Late Cretaceous paleobiogeography of the coccolithophore Braarudosphaera bigelowii is reconstructed based on 331 stratigraphic occurrences and complemented by 307 neighboring absences. During the Cenomanian B. bigelowii was found throughout the European seaways, at the base of the North America Interior Seaway, at the paleo-Atlantic margin of South America, in the Neuquen Basin, on the southern tip of the Indian plate, and on the Kerguelen Plateau. During the Late Cretaceous, its ra...

AIM: The summits of mountain ranges at mid‐latitude in the Northern Hemisphere share many ecological properties with the Arctic, including comparable climates and similar flora. We hypothesize that the orogeny during the Oligocene‐Miocene combined with global cooling led to the origin and early diversification of cold‐adapted plant lineages in these regions. Before the establishment of the Arctic cryosphere, adaptation and speciation in high elevation areas of these mountain ranges may have led ...

Abstract Over geological timescales, CO 2 levels are determined by the operation of the long term carbon cycle, and it is generally thought that changes in atmospheric CO 2 concentration have controlled variations in Earth's surface temperature over the Phanerozoic Eon. Here we compile independent estimates for global average surface temperature and atmospheric CO 2 concentration, and compare these to the predictions of box models of the long term carbon cycle COPSE and GEOCARBSULF. We find a st...

Whether the latitudinal distribution of climate-sensitive lithologies is stable through greenhouse and icehouse regimes remains unclear. Previous studies suggest that the palaeolatitudinal distribution of palaeoclimate indicators, including coals, evaporites, reefs and carbonates, has remained broadly similar since the Permian period, leading to the conclusion that atmospheric and oceanic circulation control their distribution rather than the latitudinal temperature gradient. Here we revisit a g...

Abstract Platform carbonates are a major component of the Earth System but their spatial extent through geological time is difficult to reconstruct, due to the incompleteness of the geological record, sampling heterogeneity and their intrinsic complexity. Here we use coupled ecological niche modeling and deep-time general circulation models to predict the occurrence of platform carbonates at the global scale during the Cretaceous. Specifically, niche modeling uses fuzzy logic to predict probable...
