SUBOREAL/BOREAL AMMONITE SUCCESSION AT THE OXFORDIAN/KIMMERIDGIAN BOUNDARY IN THE FLODIGARRY SECTION (STAFFIN BAY, ISLE OF SKYE, UK)

open access: yesRivista 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

Trachyteuthis covacevichi n. sp., a Late Jurassic Palaeopacific coleoid cephalopod [PDF]

open access: yesFossil Record, 2008
A new early Oxfordian coleoid cephalopod, Trachyteuthis covacevichi n. sp., is described from northern Chile. It represents the first Late Jurassic Palaeopacific vampyropod and thus considerably extends the palaeogeographic distribution of trachyteuthids.

Callovian–Oxfordian hecticoceratins from western India: Their biostratigraphic and palaeobiogeographic implications

open access: yesJournal of Palaeogeography, 2014
The Kutch Basin of western India is famous for its rich assemblages of the Callovian–Oxfordian ammonites. The family Oppelidae Douvillé is the second most diverse ammonite group after perisphinctids during the Middle–Upper Jurassic.

Thermal Volume Changes and Creep in the Callovo-Oxfordian Claystone [PDF]

open access: yesRock Mechanics and Rock Engineering, 2017
The Callovo-Oxfordian (COx) claystone is considered as a potential host rock for high-level radioactive waste disposal at great depth in France. Given the exothermic nature of radioactive wastes, a temperature elevation planned to be smaller than 100 °C will affect the host rock around the disposal cells.
