Abstract

The biostratigraphic and quantitative data of planktic foraminifera from the Agost section (Alicante, SE Spain) have been reviewed, and the relative abundance of aberrant planktic foraminifera after the Cretaceous/Paleogene (K/Pg) boundary has been estimated. Two intervals with environmental stress have been identified in the lower Danian, characterized by the increase in aberrant specimens: 1) Interval of the first 10 Ka after the K/Pg boundary, linked to the long-term effects of the Chicxulub impact; 2) Interval between 100 and 350 Ka after the K/Pg boundary, linked to the Ambelani volcanic pulse of the Deccan.
