Abstract
Abstract. The distribution and zonation of planktonic foraminifera and ostracods during the Late Coniacian – Early Maastrichtian succession in Israel was studied in detail from six surface sections. The combination of contemporaneous biozones led to a more accurate age determination of the local ostracod zones, according to the Tethyan planktonic foraminiferal zonation. The configuration of the biozones of both taxa presents more datum lines for stratigraphic correlation of the Senonian strata of Israel. Three new ostracod species were described from Campanian sediments: Cytherelloidea zinensis, Loxoconcha hebraica and Cristaeleberis ordinata.
Highlights
Late Coniacian - Maastrichtian marine formations of the Mount Scopus Group (Flexer, 1968) are widely distributed in Israel. They are mostly composed of chalks, mark, cherts and phosphorites
A renewed interest in Senonian rocks of Israel was evoked after the micropaleontological studies of Moshkovitz (1984; calcareous nannofossils) and Honigstein (1983, 1984; ostracods)
Additional biostratigraphic data on ostracods are recorded in Lipson-Benitah et al (1985; combined with foraminifera) and in Lifshitz et al (1985)
Summary
Late Coniacian - Maastrichtian marine formations of the Mount Scopus Group (Flexer, 1968) are widely distributed in Israel. Both planktonic foraminifera and ostracods were studied from the same samples, except those of the Ein Fawwar section (see Fig. 1). The subocular rib, one of the characteristic features of the mainly Paleocene species of the genus Cristaeleberis from Jordan (Bassiouni, 1971), is generally less developed in the Late Coniacian - Maastrichtian specimens from Israel (see Honigstein, 1984). Male carapace, paratype, Nahal Zin. SMA 22 (HU-6825), Zone S-5* ( X 104).
