Mouta & Borges (1926) were the first to study this lithostratigraphical unit; based onoccurrence of the bivalves Crassatella numidica Munier-Chalmas, Cardita beaumontidArchiac and Roundaireia drui Munier-Chalmas, they assigned a Senonian age to theBaba Formation. This age was confirmed by Rennies (1929) study of Mollusca from thestratotype at Baba (some 60 km to the south of the present locality); identification ofTrigonarca angolensis Rennie, T. cf. trichinopolitensis (Forbes), Nemodon natalensis(Baily), Veni
