A Late Juras- sic (KimmeridgianTithonian: Tendaguru, Tanzania) to earliest Cretaceous (Valanginian: Algoa Basin, South Africa) assemblage with stegosaurids, brachiosaurids and diplodocids is replaced by a pre-Aptian (HauterivianBarremian?) assemblage with baryonychine spinosaurids, the pholidosaurid crocodile Sarcosuchus and large iguanodontids recorded from Niger (El Rhaz Formation), Cameroon (Koum Formation), and partially from Libya (Cabao Formation) and Tuni- sia (Douiret Formation) with the shark Priohybodus arambourgi. Aptian? to Early Albian assemblages still include ig- uanodontids but spinosaurine spinosaurids replace baryonychines. Early Cenomanian assemblages (Bahariya, Kem Kem) are characterized by the association of dinosaurs (Spinosaurus, Carcharodontosaurus), sharks (Onchopristis numidus) and crocodiles (libycosuchids, stomatosuchids). It is suggested that some supposedly Early Cretaceous formations from central Africa (Galula Formation of Tanzania, dinosaur beds of Malawi) are Late Cretaceous in age. Fossil vertebrates
