The Role Of The Palaeogene Adriatic Carbonate Platform In The Spatial Distribution Of Alveolinids, Katica Drobne, Vlasta Cosovic, Alan Moro, Damir Buckovic
Turkish Journal of Earth Sciences
Sediments of the Palaeogene Adriatic carbonate platform, a distinctive palaeogeographic unit, are today exposed along the eastern Adriatic coast for a distance of 800 km and a width of 100-130 km. The large number of identified alveolinid species (69) from the Early Ypresian (Ilerdian) to the Bartonian record the dynamics of their evolution, with emphasis on the following: (1) great species diversity and great abundance in the middle Ilerdian (SBZ 7-8) followed by a sharp decline in occurrences at the Ilerdian/Cuisian transition; (2) a diversity boom in the late Ypresian (late Cuisian, SBZ 11-12) and (3) an abrupt decrease in …
