Stratigraphic correlation of a Huang et al.21; b Malinverno et al.24; c this work. The comparison tables indicate the magnetic polarity and planktonic foraminiferal and calcareous nannofossils zones. Stratigraphic extent of Selli Level equivalent sediments deposited during OAE 1a, Wezel Level, Fallot Level, 113/Jacob Level, and the Aptian–Albian boundary. The black arrows recorded decline and crisis of nannoconids. All stratigraphic scales are in age. H. Hedbergella, plan. planispira, G. Globigerinelloides L. Leupoldina, ferr. ferreolensis, Nannoc. Nannoconid, M. Microhedbergella, min. miniglobularis, P. Paraticinella.
