Abstract
The diversity and distribution of ammonites in the Tithonian and Lower Cretaceous of the Western Carpathians reflects local paleogeography. Ammonites were more diversified on the European shelf from the Tithonian to the Valanginian, despite the preservational bias in the Central Carpathian sequences. This area was intermittently connected to the Boreal Realm by seaways, through which faunal migrations took place. By contrast, ammonite assemblages (purely Tethyan) of the Zliechov Basin on the Alpine Carpathian microplate displayed maximum diversity in the Hauterivian. The most diverse Barremian and Aptian ammonite associations are found in the Godula Basin. Albian ammonites were relatively rare and only known from the borders of the Penninic Oceanic Trough.
