First radiation of Cretaceous planktonic foraminifera with radially elongate chambers at Angles (southeastern France) and biostratigraphic implications
The study of planktonic foraminifera from the Lower Cretaceous succession at Angles (Southeastern France) directly correlated with ammonites, confirms that the origin of morphotypes with radially elongated chambers occur earlier than previously recorded. In particular, the species Hedbergella semiel...
