Biostratigraphy and magnetostratigraphy of the upper Tithonian–Berriasian of the Crimean Mountains [PDF]

open access: yesCretaceous Research, 2018
Abstract Our data from studies over many years on upper Tithonian–Berriasian strata of the Crimean Mountains are summarised. Their zonal subdivision has been significantly refined using ammonites and foraminifera, as well as on the basis of calpionellid, ostracod and dinocyst distributions.

Orbital calibration of the early Tithonian - early Valanginian in the Neuquén Basin

open access: yes, 2016
Afloating orbital scale from 10 stratigraphic sections of the early Tithonian ?early Valanginian Vaca Muerta Formation has been constructed from the southernMendoza area of the Neuquén Basin. The Vaca Muerta Formation is characterizedby decimetre-scale rhythmic alternations of marls, shales and limestones, showinga well-ordered hierarchy of cycles ...
