Publication: Quantifying the paleogeographic driver of Cretaceous carbonate platform development using paleoecological niche modeling
Highlights: We use a general circulation model to simulate Cretaceous environmental conditions. We identify oceanic regions favorable to the development of platform carbonates. The ecological niche model performs well in the Aptian. It also captures the increase in platform carbonates … Continue reading
Publication: Ocean Circulation in the Toarcian (Early Jurassic): A Key Control on Deoxygenation and Carbon Burial on the European Shelf
Key Points: The southern European Shelf remained oxygenated during the Toarcian Oceanic Anoxic Event. Ocean dynamics, notably the Tethyan clockwise gyre, largely controlled bottom water oxygen concentrations on the European Shelf. Organic carbon burial in the European Shelf likely contributed … Continue reading

Publication: Glacial onset predated Late Ordovician climate cooling
Keypoints: Earth system model providing the first detailed simulation of Middle to Late Ordovician land ice growth Model/data comparison suggests a Darriwilian age for glacial onset A single ice sheet of large extent covered Gondwana during the Hirnantian glacial maximum. … Continue reading

Publication: High dependence of Ordovician ocean surface circulation on atmospheric CO2 levels
Highlights We model Early, Middle and Late Ordovician ocean surface circulation. Our basemaps are fully compatible with the most recent palaeontological databases. Synthetic maps are produced to aid the interpretation of palaeobiogeographical data. Major patterns of modelled ocean surface circulation … Continue reading
