A Tropically Hot Late Jurassic North American Sundance Sea: Evidence for the Oxfordian Warm Interval
Paleoceanography and Paleoclimatology, Volume 41, Issue 7, July 2026.Abstract The Late Jurassic greenhouse climate was characterized by elevated atmospheric CO2 (pCO2) at 600–1,000 ppm and sea‐surface temperatures substantially warmer than today. These conditions peaked during the Oxfordian, when extensive epicontinental seaways, including the North American Sundance Sea, dominated mid‐latitude paleoceanography.

On the Mobility and Potential Retention of Iodine in the Callovian–Oxfordian Formation [PDF]
Physics and Chemistry of the Earth, 2007 Abstract Iodide sorption experiments were conducted on clay stone samples originating from the Callovian–Oxfordian formation under experimental conditions as close as possible to in situ conditions. The total natural iodine content of the formation is shown to be very constant throughout the formation, ranging from 2 to 3 ppm.

Radiolarian assemblage from radiolarites of the Krš Gradac section (SW Serbia): On the way to a better reconstruction of the Middle-Late Jurassic geodynamic history of the Inner Dinarides [PDF]
Geološki Anali Balkanskoga Poluostrva, 2023 The type section of the Gonje Formation (Krš Gradac, Sjenica area) is characterized by an abundance of radiolarian tests, which, however, are gene rally recrystallized and poorly preserved.

Phanerozoic Large Igneous Province, Petroleum System, and Source Rock Links
Geophysical Monograph Series, Page 191-228., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Poly-phased fluid flow in the giant fossil pockmark of Beauvoisin, SE basin of France
BSGF - Earth Sciences Bulletin, 2020 The giant Jurassic-aged pockmark field of Beauvoisin developed in a 800 m wide depression for over 3.4 Ma during the Oxfordian; it formed below about 600 m water depth.

Poroelasticity of the Callovo–Oxfordian Claystone [PDF]
Rock Mechanics and Rock Engineering, 2016 This work is devoted to an experimental investigation of the poroelastic behavior of the Callovo–Oxfordian claystone, a potential host rock for the deep underground repository of high-level radioactive waste in France. Drained, undrained, pore pressure loading and unjacketed tests were carried out in a specially designed isotropic compression cell to ...
