Data from: Blooms of aberrant planktic foraminifera across the K/Pg boundary in the Western Tethys: causes and evolutionary implications
Here we report a detailed study of the different categories and types of abnormal morphologies in planktic foraminifera recognizable in the lowermost Danian mainly from the El Kef and Aïn Settara sections, Tunisia. Various types of abnormalities in the test morphology were identified, including prot...
