“…The dominant lithology is shale/claystone interbedded with bioturbated mudstone. This formation was interpreted as marine by Carter et al (1963), but later attributed to a regressive shoreface (Sarki Yandoka et al, 2019).…”

“…The Dukul Formation is succeeded by the Jessu Formation, the latter being characterised by interbedded mudstones and light to dark grey shales, with a few beds of marl. Lithofacies analysis of the Jessu Formation carried out by Sarki Yandoka et al (2019) showed that the formation was a progradational shoreface to offshore deposit. Overlying the Jessu Formation is the Sekule Formation which is composed of fossiliferous limestone interbedded with dark grey to grey shale.…”

The Cretaceous was punctuated by episodic flooding of continental margins forming epicontinental seas. The Trans‐Sahara Seaway was one of these epicontinental seas, connecting the Gulf of Guinea with the Tethys Ocean. In this study, data including microplankton abundances, stable carbon isotopes of organic material and elemental geochemistry were integrated with traditional sedimentological analyses from the Trans‐Sahara Seaway. The carbon isotopic data provide the first evidence that oceanic anoxic event 2 was present in the Trans‐Sahara Seaway, and palynology shows it was associated with an increase in peridinioid dinocyst abundance. A combined study of microplankton assemblages and sedimentology reveals palaeoenvironmental trends linked to sea‐level change. Lowstand system tracts were characterised by increased siliciclastic grain size, low microplankton diversity, and were dominated by Chlorophyceae. Transgressive system tracts were associated with diversity increases during rising sea level, with open marine gonyaulacoid dinocysts dominating the assemblages. Maximum flooding surfaces were recognised by the highest increase in biological diversity in argillaceous deposits. As sea level started to fall, the peridinioid dinocysts became dominant, with decreased microplankton diversity during highstand systems tracts. This combination of sedimentology and interpretation of dinocyst assemblages allows the identification of shallow to deeper marine depositional sequences of Cenomanian–Santonian strata within the Yola Sub‐basin. This approach could be used to delineate marine depositional sequences where using conventional sedimentological methods alone is very challenging.
