Marine ostracods from the Ladinian of Slovenia

Abstract

The Ladinian stage in the Middle Triassic is poorly documented in terms of marine ostracods diversity. Silicified ostracods have been retrieved from three sections of Middle Triassic age in Slovenia (Rob, Kamna Gorica, Vintarjevec), providing new insights into the taxonomic structure and distribution. Sixty-four species belonging to 33 genera and 13 families are here reported, including two newly described species: Mirabairdia slovenica sp. nov. and Leviella alexi sp. nov. Not considering assemblages that are significantly incomplete, the assemblages point to stable subtidal conditions. The occurrence of several species shows the existence of migration routes between the Germanic Basin and the Slovenian Basin in the Ladinian.
