Late Paleozoic microfaunas in the pebbles of the Podlipoglav conglomerate, Central Slovenia

Abstract

The Paleozoic conglomerate at Podlipoglav in the transitional area between the External and Internal Dinarides of Slovenia contains limestone pebbles that have been examined micropaleontologically. The recovered conodont faunas are marked by the obvious absence of shallow-water taxa. The Lower to Middle Devonian faunas are characterized by relatively abundant polygnathids that are assigned to the Emsian and early Eifelian excavatus-nothoperbonus, laticostatus and costatus Zones. The Pennsylvanian conodont faunas contain relatively deep-water Neolochriea or gondolellids indicating an early Bashkirian and Moscovian age. A presence of the radiolarian species Pseudoalbaillella nodosa suggests a deep-water setting during the early Moscovian and it is the oldest yet-reported albaillellid finding in Central Europe.
