Barremian: Fossiliferous formations, Stratigraphic definitions & Overview

The Barremian is an age in the geologic timescale (or a chronostratigraphic stage) between 125.77 Ma (million years ago) and 121.4 ± 0.6 Ma (Historically, this stage was placed at 129.4 million to approximately 125 million years ago). It is a subdivision of the Early Cretaceous Epoch (or Lower Cretaceous Series). It is preceded by the Hauterivian and…
