Abstract: Along the eastern border of the Gilău Mountains crop out carbonate deposits which were formed during the Late Cretaceous (Santonian-Campanian). These deposits are characterized by a significant presence of rudists and were formed on the border of a narrow marine shelf. The typical feature is represented by the dominance of the coral-rudist associations. The paleontological study of these deposits revealed the presence of four evolutionary stages when corals, rudists and red calcareous algae stabilised and colonised the sediment depending on the relative sea level evolution. All the evolutionary stages have been included into an idealised ecological sequence. | |||||||
