Rudist-bearing Upper Cretaceous deposits of Medvednica Mountain, Northern Croatia.

The Upper Cretaceous deposits of Medvednica Mt. (Polšak, 1981) have been studied from four localities (Mikulić potok, Donje and Gornje Orešje and Vidovec-Planina). There rudist congregations within transgressive sediments overly Paleozoic or Triassic deposits. . Scarce presence of rudists within relatively broad area of transgressive deposits coincides with absence of distinct shoal/barrier deposits. It could be presumed that rudist congregations within transgressive sediments are scattered probably due to more or less favorable paleoecological conditions for their larval settlement.
