TY - JOUR ID - 31562 TI - A NEW SPECIES OF HETEROSTEGINA IN MIDDLE PALEOCENE FROM THE KHUZESTAN AREA (S.W. IRAN) JO - Journal of Sciences, Islamic Republic of Iran JA - JSCIENCES LA - en SN - 1016-1104 Y1 - 1993 PY - 1993 VL - 4 IS - 3 SP - EP - DO - N2 - 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.
