Abstract

Na jugozapadnom obodu Medvednice, pokraj okretišta Dubravica, istraživani su glinoviti vapnenci. U njima je nađena bogata morska mikrofauna, među kojom se ističu foraminifere, ostrakodi, školjkaši, puževi, skafopodi, spikule spužvi, bodlje ježinaca, mahovnjaci, otoliti i drugi riblji ostaci. Okoliš taloženja određen je kao srednji šelf, najvjerojatnije oko 50-ak m dubine. Gledajući očuvanost fosilnih jedinki utvrđeno je da je došlo do miješanja plitkomorske i dubokomorske faune, moguće za vrijeme jačih oluja. Starost naslaga ustanovljena je kao baden.

Abstract (english)

At the southwestern slopes of Mt. Medvednica, near the bus terminal Dubravica, argilaceous limestones occur. They comprise rich marine microfossil assemblage, including foraminifers, ostracods, bivalves, gastropods, scaphopods, sponges, echinoids, bryozoans and fish remains. Depositional environment is presumed as the middle shelf, around 50 m deep. Considering the mode of preservation, shallow- marine and open sea fauna was mixed, probably during some severe storms. Age is estimated as the Badenian.
