A new Cenomanian ichthyofauna from southeastern Morocco and its relationships with other early Late Cretaceous Moroccan faunas

A new ichthyofauna from southeastern Morocco, comprising five forms, is bri efly discussed. The faunal composition differs from the Early Cenomanian Ke m Kem and Early Turonian Goulmima assemblages, but is close to that from Je bel Tselfat. We propose a Late Cenomanian age for the new fauna and that fr om Jebel Tselfat. The evolution of these fish assemblages shows the Morocca n fish faunas to have been related to those from South America until at lea st the Early Turonian. Central Tethyan influence on faunas seems to have be en restricted to a short period of time during the beginning of the Late Ce nomanian transgressive phase.
