Abstract

A rich ammonite fauna was collected from the Dedina section, which is part of the Getic nappe system of the Serbian Dacia Megaunit. More than three hundred ammonites were collected from the light grey to reddish bioclastic limestones of the lower part and light grey marlstones of the upper part. From this fauna, 10 genera with 17 species were described, and 4 aptychi species were recorded. The ammonites belong to the suborders Haploceratina, Perisphinctina, Olcostephanina, and Ancyloceratina. Perisphinctids belong to the genera Pseudosubplanites, Hegaratella, Delphinella, Substeueroceras, Malbosiceras, and Strambergella. Based on the occurrence of Pseudosubplanites grandis, the studied section can be considered to belong to the Grandis ammonite Subzone of the upper part of the lower Berriasian. The association described here appears to be close to the coeval ammonite association in Crimea.
