Abstract
The late Maastrichtian deposits of the Padriciano and Dolenja Vas sequences are mainly characterized by limestones of restricted and very restricted settings. These limestones present a monospecific or oligospecific rudist fauna characterized by Apricardia specimens and the Bournonia-Apricardia assemblage, respectively. The Maastrichtian beds of Padriciano and Dolenja Vas are capped by a "breccia" at the K/T boundary, which records the decline of the rudists and other Cretaceous taxa such as the foraminifers Fleuryana adriatica DE CASTRO, DROBNE & GUŠIC, Rhapydionina liburnica (STACHE), Cuneolina ketini INAN and Cuneolina cylindrica HENSON.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
