Langobardian beds with daonellas and posidonias in Slovenia


  • Bogdan Jurkovšek


Individual species of genera Daonella and Posidonia are excellent index fossils, which are especially important in subdividing the Ladinian beds. Twelve sections have been investigated in Slovenia recently. Rich lamellibranch fauna in them proved the Langobardian age of the beds. The most abundant and most frequent Langobardian species is Daonella lommeli (Wissmann), vvhich was found in all studied sections. Well preserved specimens from Korošica in the Kamnik Alps allowed a detailed study of its ontogenetic evolution. In the same section, for the first time in Slovenia, was also found the species Posidonia pannonica Mojsisovics. Another very frequent Langobardian species in Slovenia is Posidonia wengensis Wissmann, which can be rockforming. Parallel studies of conodonts, ammonites and daonellas at Oblakov vrh position it in the Langobardian substage.
