A NEW SPECIES OF HETEROSTEGINA IN MIDDLE PALEOCENE FROM THE KHUZESTAN AREA (S.W. IRAN)

Abstract
New evidence gained by the study of Foraminifera from Khuzestan province in
southwest Iran reveals that the basal limit of the genus Heterostegina is not
restricted to the Eocene epoch. By introducing a new species of this genus (H.
rezvaninejadi), this study shows that the early appearance of this genus should be lowered down further still, at least, into the Middle Paleocene.
