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.

A microstructure insight into the water retention properties of the Callovo-Oxfordian claystone
E3S Web of Conferences, 2016 The effect of changes in suction on the microstructure of the Callovo-Oxfordian claystone along wetting and drying paths was investigated by using mercury intrusion porosimetry.

Rivista Italiana di Paleontologia e Stratigrafia, 2004 The Flodigarry section at Staffin Bay, Isle of Skye, has yielded numerous ammonites both of Subboreal and Boreal affinity. This has enabled close correlation of the Subboreal and Boreal ammonite zonations, and provided new palaeontological data on levels

First record of a Late Jurassic rhamphorhynchine pterosaur from Gondwana [PDF]
Acta Palaeontologica Polonica, 2021 We describe partial remains of a non-pterodactyloid pterosaur from Upper Jurassic levels of the Atacama Desert in northern Chile. The material includes a left humerus, a possible dorsal vertebra, and the shaft of a wing phalanx, all preserved in three ...

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.
