Given that previous studies have suggested that the BIFs from the Nyong Group probably precipitated in a back-arc basin or continental margin environment (Ganno et al. 2017 ; Soh Tamehe et al. 2018 , 2021; Moudioh et al. 2020 ; Nzepang Tankwa et al. 2020 ), we...

Offodile and Reyment (1976) found a possible Allocrioceras annulatum close to or within this section; this species is typical for the late Cenomanian of the Western Interior Basin of North America and elsewhere. Accordingly, a late (or latest) Cenomanian age for the Aboine River Section can be inferred...
