INTRODUCTION

Of the eight sites drilled on Leg 42A, all penetratedPleistocene sediments, all except Site 377 penetratedPliocene sediments, and all but Holes 373A and 377penetrated the Mediterranean Evaporite Formation.However, this formation could be dated paleontologi-cally only at Sites 372, 375, and 376, and no real agedetermination could be given for evaporites at Sites371,374, and 378.

Miocene sediments were recovered at Sites 372, 375,and 377 and penetration was as far as lower Burdiga-lian at Sites 372 and 375.

Range charts are provided here for planktonic andbenthonic foraminifers but not for nannofossils, asthese appear elsewhere (Müller, this volume). Also dis-played is other information gleaned by the shipboardpaleontologists both on other fossil groups and on min-erals recorded in the sand-size fraction of their sievedsamples greater than 63 microns.

Range Charts By R. Wright: All Sites

Note: The distributional data shown in these tablesare not based on the study of equal sized samples noron samples which were equally spaced stratigraphi-cally. Samples from Sites 372, 374, and 376 were stud-ied in much greater detail than those of the other sites;samples from the Messinian Stage and the stratigraphicintervals just above and below it were examined moreclosely than those of other intervals. The informationin the tables reflects this bias. The greatest number ofspecies is shown to be present in samples from theseabove mentioned sites and intervals, but this is prob-ably a consequence only of their intense examination.

Although 79 of the 211 samples were examinedquantitatively, the only information shown on thecharts is qualitative—the presence of taxa in a sample.

The biostratigraphic zonation used in these charts isbased on the studies of planktonic foraminifers andcalcareous nannoplankton by the other shipboard pale-ontologists. Where major differences in zonation occur,e.g., Site 372, Core 9, the different interpretations areshown on the charts.

Instead of dividing the Pliocene into the standardstages: Zanclean (Tabianian) and Piacenzian, the

1095

planktonic foraminiferal biozonation of Cita (1975) isused here to provide further precision. Standard stagenames are used for the Miocene strata.

Taxonomic notes and illustrations of the most abun-dant species are given in Wright (this volume).

The charts are:(25) Site 371(26) Site 372(27) Hole 373A(28) Site 374(29) Site 375(30) Site 376(31) Site 377(32) Holes 378/378A

Range-Charts By C. Miiller (nannofossils)

Range charts for all sites, except Hole 373A andSite 377, appear in Müller, this volume.
