Abstract

Sediments from ODP Holes 699A, 700B, 702B, 703A, and 704B were studied in order to determine and to understand the distribution of Bolboforma. Ten Bolboforma taxa were detected in the 294 samples analyzed. Based on Bolboforma species, a zonation correlated to the paleomagnetic record is proposed for the late middle Eocene to early Oligocene. Four biozones can be defined: the Bolboforma indistincta Zone for the lower part of the upper middle Eocene sequence, the Bolboforma eocena Zone for the upper part of the upper middle Eocene to upper Eocene, the Bolboforma geomaris Zone for the upper Eocene, and the Bolboforma latdorfensis Zone for the lower Oligocene sequence.
