Farah Fatml Geological Survey of Pakistan, 42R PECHS Block 6, Karachi, Pakistan ABSTRACT Sixty-two ostracode species were identified from late Paleocene and early Eocene sedimentary rocks recovered from core UAJ-1. The core was taken at Jhimpir, approximately 10 km northwest of Sonda, in the Meting-Jhimpir coal field, southern Sindh Province. The 120 m interval cored includes rocks of the Meting Limestone Member of the Laki Formation, the Sohnari Formation, and rocks questionably representing the Lakhra Formation. Based on the stratigraphic distribution of the ostracode species, three assemblage zones are recognized. The lowest assemblage zone ranges from 176 to 143 m in the Sohnari/Lakhra transition.
