Abstract
A new genus is proposed to accommodate strongly ornamented hedbergellids of the latest Albian-earliest Cenomanian. Paracostellagerina nov. gen. is characterized by asymmetrical test ornamentation, rugosities, and costellae that are meridionally arranged on the umbilical side and parallel to the periphery on the spiral side. This genus has a global distribution within tropical-subtropical latitudes and, because of its short stratigraphic range, it is a valuable biomarker for correlation of uppermost Albian-lowermost Cenomanian sequences.
