...Z. R. El-Naggar Abstract Forty-nine species and subspecies of planktonic foraminifera are recorded in the uppermost member of the Thanet formation (the Reculver silts) and in the overlying Reading oyster bed. These include reworked specimens of late Senonian and of early and middle Paleocene ages...
