Publication Abstract

Seventy three rock samples were extracted from the Paleocene interval (fourty three meter) in the
Dineigil area, SouthWestern Desert, Egypt. The ostracod assemblages in these samples were qualitatively
studied. The ostracods are well preserved which allowed us to recognize thirty two species belonging to
eighteen genera and nine families. The recorded ostracods could be differentiated into two assemblages.
The first assemblage comprises an overlapping combination of the Esna Type and Garra Type and indicates
an inner-middle shelf environment (50e70 m depth). The second one comprises a combination of
the Tethyan Type and Esna Type, indicating a transitional environment from the middle shelf to the outer
shelf (deep infraneritic). The paleobiogeographic distribution of the investigated ostracods shows a
strong resemblance to those in many areas of North Africa and Middle East, and a slight affinity to those
in West Africa and the South Atlantic.
