Sažetak
The Upper Eocene Benkovac Stone mb. is a shallow- marine, approximately 120 m thick succession of calciclastic deposits, mostly cropping out in a vicinity of Benkovac in the northern Dalmatia. It represents a middle part of Middle Eocene to Lower Oligocene Promina Basin deposits, more than 2000 m thick succession from deep-marine to alluvial facies (MRINJEK et al., 2005). The Benkovac Stone mb. is commonly used architectural and building stone, and is well-known for its excellently preserved trace fossils, which were never, up to now, studied in detail. Two major lithological types within the Benkovac Stone mb. are calciclastic sandstones and calciclastic mudstones. Sandstones were deposited by storms and mudstones were mostly a product of background sedimentation within offshore-transition zone. Sandstones and mudstones are characterized by different trace fossils ichnoassemblages, and individual ichnoassemblages are laterally very variable.
