Cenomanian Trocholinas from Nigeria
Micropaleontology, 1968Limestones belonging to the Cenomanian Odukpani formation are exposed in southeastern Nigeria, and in them a new species of foraminifer, Trocholina odukpaniensis, as well as fragments of algae and mollusk shells, are preserved as calcite casts. Revision of published material necessitates a new diagnosis of the genus.

Cenomanian and Turonian echinoids from Nigeria
Geobios, 1997Cenomanian to Middle Turonian echinoid faunas from Nigeria are described for the first time on the basis of new collections sampled during recent geological investigations in the Benue Trough. Five Cenomanian species have been recognized: Tetragramma variolare, Heterodiadema libycum, Micropedina olisiponensis, Mecaster pseudofourneli, Mecaster sp.

Le développement de la stratigraphie au xixesiècle connaît une innovation décisive en 1842 lorsqu’Alcide d’Orbigny intro-duit la notion d’étage géologique. Les étages sont définis dans unecertaine zone géographique qui montre une coupe type, ou stra-totype, permettant l’identification de l’unité géologique.

The late Cenomanian event in eastern England
Historical Biology, 1991The Cenomanian/Turonian boundary event has been fully documented from a series of localities between Flamborough Head in Humberside and Marham in Norfolk. The carbon isotope excursion can be identified and extrapolated to all the studied sections using bed‐by‐bed correlation.

The Cenomanian and Turonian in NortheasternCentral Asia
Cretaceous Research, 1984Abstract Northeastern Central Asia during the Albian and Early Cenomanianwas one of the peripheral basins of the Central Asian region. The similarity of their freshwater molluscs makes it possible to correlate isolated series in these two regions.

Cenomanian phosphorites in the former Soviet Union
Sedimentary Geology, 1994Abstract Cenomanian nodular phosphorites are widespread over vast areas of the Precambrian East European Platform (EEP). They are found in various parts of the Cenomanian forming thicker and richer beds close to the Cenomian/Turonian boundary. They are encountered nearly ubiquitously, but are concentrated on synsedimentary highs in thin and condensed

The unusual cenomanian oyster Pycnodonte biauriculatum
Geobios, 1984Abstract From Albian to Maastrichtian times oysters belonging to the genus Pycnodonte were a major component of the bivalve fauna. In marly and sandy Cenomanian facies several oysters occurred in banks; one of them is Pycnodonte (P.) biauriculatum which is distributed from the Iberian Peninsula to Central Asia.
