Haughton(1925: 264) reported doubtfully Turanian ammonites from the Cuanza basin; these arein the South African Museum and form part of the same Upper Turonian fauna recordedsubsequently by Basse (1963). Thiele (1933) identified Lower Turonian Mammitesconciliatus (Stoliczka) in faunas from Novo Redondo, but this is a misidentification of theouter horned whorls of Middle Cenomanian Cunningtoniceras.
