The late Berriasian early evolutionary burst of the Orbitolinidae: New insights into taxonomy, origin, diversification and phylogeny of the family based on data from eastern Serbia

Carnets de Géologie, 2021
New data from the Carpatho-Balkanides of eastern Serbia evidence the more or less near-simultaneous "explosive" first appearances of several genera of the Orbitolinidae in the late Berriasian.

Palynology of the Late Berriasian to Early Hauterivian of the Tethyan Realm in SE France: biostratigraphy and taxonomy of the Vergol (Montbrun-les-Bains) and La Charce (Serre de l’Âne) sections, Vocontian Basin

Micropaleontology
Quantitative palynofloral analysis of late Berriasian to early Hauterivian aged sediments from the Vocontian Basin of southeast France has involved fifty-four outcrop samples from Vergol (Montbrun-les-Bains) and twenty-seven from La Charce (Serre de l ...

Cribellopsis delicatula n. sp., an early Orbitolinidae from the upper Berriasian to lower Valanginian of SE France, Switzerland and Iran

Micropaleontology, 2020
Cribellopsis Arnaud-Vanneau (upper Berriasian-Albian) represents a rather simple structured orbitolinid species that are classically differentiated above all by dimensional and morphological criteria.
