Berriasian Stage of the Crimean Mountains: Zonal subdivisions and correlation

Stratigraphy and Geological Correlation, 2008
Biostratigraphy of the Berriasian Stage in the Crimean Mountains is specified and substantiated. Fragments of all the standard stage zones (jacobi, occitanica, and boissieri) are distinguished based on the found index species, and position of the Jurassic-Cretaceous boundary is targeted.

Early Cretaceous (Berriasian) microflora on Mount Hermon

Journal of African Earth Sciences (and the Middle East), 1991
Abstract An exposure near Ein Qinya (E. 29375/N. 21940), Mount Hermon yielded numerous miospores most probably of Berriasian age, which are possibly the oldest Cretaceous fossils above the Jurassic Cretaceous plane of unconformity in this area. These miosporres are shown to be useful for correlation of assemblages from the Purbeckian facies of ...

Magnetostratigraphy of the Berriasian stratotype section (Berrias, France)

Earth and Planetary Science Letters, 1985
Abstract The Berriasian (Early Cretaceous) stratotype section (Berrias, Ardeche, France), 30 m thick, consists of well-bedded blue-gray pelagic limestone. The biostratigraphic subdivision of this section is based on ammonite and calpionellid zonations. Magnetostratigraphic study has yielded a reliable magnetic polarity sequence.

Zapaliinae, a new subfamily of Tithonian–Berriasian ataxioceratid ammonites

PalZ, 2017
The recent recognition of the earliest Andean Tithonian ammonite fauna (Picunleufuense Zone) has allowed a balanced classification of the ataxioceratid ammonites, reflecting their phylogenetic relationships. The Picunleufuense Zone fauna, first recognized in the Neuquen Basin at the base of the Vaca Muerta Formation, is represented by numerous records ...

Pterosaurs from the Lower Cretaceous (?Berriasian) of Anoual, Morocco

Annales de Paléontologie, 2000
Abstract A report on the pterosaurian remains from the Lower Cretaceous of Anoual, Morocco, is presented. The material consists of teeth possibly documenting two groups. One of them cannot be clearly established but might be ornithocheirid, while the most numerous teeth are reminiscent of those of gnathosaurine.

A new Berriasian to Turonian carbon isotope stratigraphy for the Boreal Realm

2020
<p>An upper Berriasian to mid-Turonian composite carbon isotope record has been compiled based on 13 drill cores and more than 4500 measurements. The total record comprises a composite thickness of about 1300 m. All cores are situated in the larger Hanover area, which represents the depocenter of the Lower Saxony Basin in early ...

Radiolarians of the Volgian and Berriasian stages of the North of Central Siberia

Stratigraphy and Geological Correlation, 2011
The stratigraphic distribution of radiolarians in the Nordvik reverence section of the Volgian Stage was studied and analyzed. The Arctocapsula magna Bragin assemblage of the middle Volgian and the Arctocapsula perforata Bragin assemblage of the late Volgian-early Berriasian are distinguished in the section.

Tirnovella occitanica Zone of the Berriasian in the Feodosia region (Eastern Crimea)

Moscow University Bulletin. Series 4. Geology, 2019
For the first time during the last 100 years, the presence of Tirnovella occitanica ammonite Zone in the Berriasian section of Feodosia was confirmed. The results of sedimentological, bio- and magnetostratigraphic study of this interval are discussed in the paper.

New occurrences of heteromorph ammonites in the Berriasian-Valanginian of the Crimean mountains

Paleontological Journal, 2011
A new species, Bochianites (?) ambiguus sp. nov., is described from the Lower Berriasian of the Eastern Crimea. It is proposed that the name B. laevis Liu, 1988 be used instead of B. levis Arkadiev, 2008, as the former is a senior synonym and homonym.

Correlation of Tethyan and Boreal Berriasian – Barremian strata with emphasis on strata in the subsurface of the Netherlands

Cretaceous Research, 2003
Abstract The standard Tethyan Berriasian–Barremian successions of France and Spain are correlated with the Boreal successions of England, Germany and the Netherlands. Special emphasis is placed on the correlation and sequence stratigraphy of the main hydrocarbon-producing strata of the Berriasian–Barremian stages in the four main basins in the ...
