Upper Kimmeridgian stratigraphy of Aylesbury, Buckinghamshire
Proceedings of the Geologists' Association, 1991Field work carried out in Aylesbury in 1987 demonstrated that the Upper Kimmeridge Clay attains 31 m thickness and has a minor non-sequence at its base. The sequence fits well with the trend of gradual thinning southwestwards, from the relatively thick development of the Wash area to the thin sequence deposited over the Oxford Shallows.

Facies, Cycles, and Controls on the Evolution of a Keep-Up Carbonate Platform (Kimmeridgian, Swiss Jura) [PDF]
Sedimentology, 2005 During the Late Jurassic, accelerated ocean-floor spreading and associated sea-level rise were responsible for a worldwide transgression, which reached its maximum in the Late Kimmeridgian.

PROTOGLOBIGERINIDS OF THE EARLY KIMMERIDGIAN OF THE JURA MOUNTAINS (FRANCE)
The Journal of Foraminiferal Research, 2013A detailed investigation of the protoglobigerinids from the lower Kimmeridgian section at Les Bouchoux, Jura Mountains, France, has been carried out by study of thin sections and acetolysis extractions. This predominantly indurated carbonate succession represents peri-platform, hemipelagic deposits, well-dated by ammonites.

Kimmeridgian palaeogeography and basin evolution of northeastern Iberia
Palaeogeography, Palaeoclimatology, Palaeoecology, 2001Abstract Two sedimentary basins were developed during the Kimmeridgian in the northeastern part of Iberia: the Basque-Cantabrian Basin, to the northwest, and the Iberian Basin, to the east. These basins were mainly filled by carbonates deposited in a shallow epicontinental sea that was connected to the open marine realms of both the North Atlantic ...

Biostratigraphy of the highest Kimmeridgian and Lower Volgian in Poland
Geobios, 1994Abstract In Poland, the ammonite succession in several continuous and expanded sections makes it possible to recognize the Eudoxus and Autissiodorensis Zones in the Upper Kimmeridgian as well as the Klimovi, Sokolovi, Pseudoscythica and Tenuicostata Zones in the Lower Volgian, and to reconstruct an evolutionary lineage leading from Discosphinctoides ...

Towards a unified Kimmeridgian Stage
Petroleum Geoscience, 1995Considerable confusion exists in the interpretation of the term Kimmeridgian. As the Kimmeridge Clay Formation is the principal source rock in the northern North Sea, this confusion has important implications for geoscientists working there. The source of the confusion is historical, but the introduction of the Bolonian Stage as a local secondary ...

Jurassic (Toarcian to Kimmeridgian) dinoflagellate cysts and paleoclimates
Palynology, 1999Abstract Multivariate statistics have been used to identify the paleoclimatic‐paleoecological affinities of most European Jurassic (Toarcian to Kimmeridgian) dinoflagellate cyst taxa. These analyses were then used to construct dinoflagellate cyst diagrams (abbreviated to ‘cyst diagrams'), which are analogous to pollen diagrams.

The dinosaur tracksite of Loulle (early Kimmeridgian; Jura, France)
Geobios, 2016Abstract More than 1500 sauropod and theropod tracks have been discovered and excavated on the floor of a disused 3800 m 2 quarry, near the village of Loulle (French Jura). These levels correspond to a tidal-flat environment, from intertidal to supratidal zone, dated from the earliest Kimmeridgian (∼157 M.a.).

A Mammalian Fauna from the Kimmeridgian of Portugal
Nature, 1961A MAMMALIAN fauna, consisting of 14 specimens, has been collected from the small Guimarota coal pit, near Leira. The age has been determined as Kimmeridgian by means of the ostracods and characeans. The pit is still in operation and it seems possible to obtain a good fauna, qualitatively as well as quantitatively.
