" Globigerina ciperoensis ", atypically giant planktonic foraminifers from the Oligocene of the Haute-Savoie, France

Very rare giant planktonic foraminifers which are here provisionally attributed to "Globigerina ciperoensis" have been discovered in flysch sediments from the Oligocene (Globigerina ampliapertura planktonic foraminiferal P20 zone) of the Haute-Savoie in France. These forms attain a diamete...
