THE MEDITERRANEAN LOWER CRETACEOUS

— The upper part of the Berriasian is demonstrated by Malbosiceras malbosi
(P i с t.), found at 1001.60 in at R-3 Junak.
— Calpionella alpina L о г., Tintinnopsella carpathica (M u r g., F i 1.), Calpionellopsis
sp., Calpionellopsis simplex (С о 1.) and Calpionellopsis oblonga (C a d.)
are found in R-6 Sultanci at 1331.50 m.

This association characterizes the upper part of the Berriasian (calpionellid
zone D 2-3, after R e m a n e, 1963).
The Valanginian in the Eastern Fore-Balkan is represented by terrigenous,
clayey-calcareous and mixed rocks (Zlatarica, Hànevci, Tica and Kamcija Formations).
The differentiation of the Valanginian from the Berriasian is performed by
means of many ammonite taxa occurring frequently in the outcrops.
In the southern part of the Elena region the Valanginian is revealed in the
northern limb of the Bujnovci anticline, where it is represented by aleuritic marls and
mixed rocks (Hànevci Formation), characterized by rich ammonite associations
(H и к о л о в, 1960; N i к о 1 о v, 1982).
In the north, in the Elena and Bukak anticlines, Valanginian sediments are
revealed over comparatively wider areas, enveloping the Tithonian-Berriasian
core of the Elena anticline and the Berriasian core of the Bukak anticline. They
are represented by sandy-marl rocks (Zlatarica Formation) and by marls (the base
of the Kamcija Formation) (Fig. 11).
