Euhystricoceras is confined to Lower Cenomanian strata while the remaining forms are typical of the Middle Cenomanian. The only Upper Cenomanian. Upper Cretaceous Series Lower Cretaceous Series Fig. 1. The Cretaceous outcrop in Nigeria. After Reyment 1955. species so far recorded (Reyment & Tait 1972) is Metoicoccras aff. ornatum Moreman (= M. whitei Hyatt), which indicates an uppermost Cenomanian age (Kennedy 1971). The Lower Turonian of Nigeria is very rich in ammonites (Reyment 1954a, 19546, 1955; Barber 1957), although Upper Turonian strata appear to be lacking in diagnostic fossils. The Coniacian is well established by the presence of the ammonites Solgen'tes, Forresteria, Peroniceras (Peroniceras), P. (Reginai- tes), Tissotia, and Gauthiericeras, Santonian (?Lower) is known from Nigeria.
