Sažetak

It has been established that the breccias of the Jelar Layers in the regions of Drniš (Dalmatia) and Dabrica (Hercegovina) have been formed in Middle Eocene. These strata are spread over rather big areas in the western part of the Outer Dinarides but so far their definite age couldn't be established, and therefore they have been designated in general as Paleogenic. The Middle Eocenic age in the mentioned regions has been determined by their superposition. In the floor there are foraminiferal limestones of the older part of Middle Eocene, or Upper Cretaceous limestones, and in the roof Promina Beds of Younger Paleogene. By analyses of limestone nannofossils it could be proved that the younger part of the Promina Beds in the locus typicus belongs to the Lower Oligocene while the older part in Dabrica corresponds to the younger part of Middle Eocene. The Jelar Beds are a constituent of very complicated tectonic structures formed before the deposition of Promina Beds.
