Remarks on the Toarcian–Aalenian fossil assemblage of the Kis-Teke Hill, Gerecse Mts (Hungary)

The red, nodular marl beds of Toarcian-Aalenian age of the Kis-Teke Hill yielded a rich fossil assemblage consisting of gastropods, bivalves, ammonites, belemnites and brachiopods. The ammonite fauna proved to be especially abundant and diverse and the relatively high percentage of Ammonitina allowed a biostratigraphical subdivision of the section. Beside representatives of taxa characteristic of the peri-Mediterranean Jurassic some rare genera including Urkutites, Rarenodia, Praerycites and Staufenia have also been encountered. These and some other interesting forms are described
