Stratigraphy
Stratigraphic resolution:group of beds
Stratigraphy comments: Lower limestone, containing Neoschwagerina cf. globosa (now Yabeina globosa), Sumatrina annae, "Fusulina exilis", and Schwagerina douvillei (now Verbeekina douvillei) according to Mansuy. Fontaine (1961) reports Neoschwagerina craticulifera. The fusulinids suggest a Wordian age.
