Nummulites laevigatus (Bruguíere, 1792). Diagnosis. Planispiral, involute, lenticular to globular, spire tight with numerous whorls. Many simple chambers per whorl, which are rather equidimensional, septa curved back at the periphery and may be sigmoidal. The marginal cord is well developed. Characters and attributes (means and standard deviations) for Nummulites and comparison with Palaeonummulites and Operculinoides are given in Table 2 . Range. Late Paleocene to Oligocene.
