Palaeobiogeography of Early Cretaceous (Berriasian–Barremian) calcareous nannoplankton
Marine Micropaleontology, 2000In order to assess Early Cretaceous nannoplankton biogeography, we studied a series of sites which provide a north-south transect across the Atlantic Ocean, supplemented by sections from the North Sea Basin, Barents Sea, Falkland Plateau, Weddell Sea (Antarctica), Argo Abyssal Plain (NW of Australia) and Neuquen Basin (Argentina).

Reconstruction of a berriasian lacustrine paleoenvironment in the Cameros basin (Spain)
Palaeogeography, Palaeoclimatology, Palaeoecology, 1989Abstract From Kimmeridgian to Valanginian, the northern part of the Iberian plate broke up into several graben systems, one of which is the Cameros basin in the northwestern part of the Iberian Range. The infill consists of fluvial-clastic and lacustrine or evaporitic carbonate rocks. During the Berriasian, a lacustrine complex developed.

Early Cretaceous (Berriasian) microflora on Mount Hermon
Journal of African Earth Sciences (and the Middle East), 1991Abstract 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 ...

Berriasian Stage of the Crimean Mountains: Zonal subdivisions and correlation
Stratigraphy and Geological Correlation, 2008Biostratigraphy 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.

Magnetostratigraphy of the Berriasian stratotype section (Berrias, France)
Earth and Planetary Science Letters, 1985Abstract 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, 2017The 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 ...

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 ...

Pterosaurs from the Lower Cretaceous (?Berriasian) of Anoual, Morocco
Annales de Paléontologie, 2000Abstract 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.
