Abstract

The Cenomanian-Turonian boundary represents a time of biotic changes affecting the diversity of larger foraminifera in shallow-water carbonate platform facies. Apart of the several taxa that suffered extinction, there is an additional cluster showing some stratigraphic occurrences before and after the CTB. Here we report a further example from the Cenomanian of the Mount Pastrik (Albanian-Kosovan boundary) that is represented by a new species within the Peneroplidae, Vandenbroeckia causae sp. nov. So far, representatives of this genus were only reported from the Campanian and Maastrichtian. The retrieval of Vandenbroeckia before CTB suggests that the genus escaped the extinction, re-appearing in the uppermost Cretaceous under a renewed specific status.
