The boundary of the Turonian and Coniacian of the North-Western Caucasus
Moscow University Bulletin. Series 4. Geology, 2022The results of a comprehensive study of the boundaries of the Turonian-Coniacian in the Upper Cretaceous deposits of the Abinsky region of the North-Western Caucasus, composed of rhythmically constructed carbonate strata of the hemipelagic type, are presented. Biostratigraphic analysis of foraminifera complexes made it possible to identify zones in the

Turonian to neogene palaeokarst in Israel
Palaeogeography, Palaeoclimatology, Palaeoecology, 1983Abstract The extensive karstic system found today in Cretaceous carbonates in central and northern Israel has been developing since Late Turonian times. Initial Late Turonian karstic activity is evidenced by small sand-filled solution cavities within the upper Turonian sequence.

In NE Mexico, the Cenomanian-Turonian plattenkalk of Vallecillo (state of Nuevo Leon) and the Turonian-Coniacian plattenkalk of Muzquiz (state of Coahuila) yield abundant fossil vertebrates and invertebrates with an exceptional preservation of soft parts. Inoceramid bivalves are the only benthic organisms in both deposits.

Cretaceous Research, 1993
Abstract In the central Iberian Ranges the Cenomanian-Turonian boundary is located within a 3rd-order depositional sequence. Sedimentation began following an Atlantic transgression which flooded the Iberian plate from its northern margin. Facies are deepest, mainly hemipelagic, in the north (marls and nodular limestones with ammonites, echinids and ...

An Upper Cenomanian to Lower Turonian section has been sampled in the vicinity of Ganuza, northern Spain. Ammonoids, inoceramids and microfossils including foraminifera and calcareous nannofossils have been studied. We recognize three planktonic foraminiferal biozones: theRotalipora cushmani,Whiteinella archaeocretaceaandHelvetoglobotruncana ...

Foraminifera of the Type Turonian
Micropaleontology, 1966The Turonian type section (upper Cretaceous of the Paris basin near Tours), as defined by Lecointre in accordance with d9Orbigny9s original concept, is briefly described to indicate the stratigraphic position of the samples studied. Foraminifera occur in the lower part of the section exclusively; fifteen species, two of them new, are discussed and ...

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.

Flowers of Turonian Magnoliidae and their implications
1994Recently discovered fossil flowers of Magnoliidae from Atlantic Coastal Plain deposits of Turonian age are considered in the context of the overall fossil record of magnoliid reproductive remains. The assemblage of fossils from these Turonian localities is diverse and affects our understanding of the history of reproductive structures in the ...

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.
