David M. Martill & Paulo M. Brito, First record of Calamopleurus (Actinopterygii: Halecomorphi: Amiidae) from the Crato Formation (Lower Cretaceous) of north-east Brazil. Oryctos 3, 3-8.
A partial skeleton represents the first occurrence of the amiid (Actinopterygii: Halecomorphi: Amiidae) Calamopleurus from the Nova Olinda Member of the Crato Formation (Aptian) of north east Brazil. The new specimen is further evidence that the Crato Formation ichthyofauna is similar to that of the slightly younger Romualdo Member of the Santana Formation of the same sedimentary basin. The extended temporal range, ?Aptian to ?Cenomanian, for this genus rules out its usefulness as a biostratigraphic indicator for the Araripe Basin.
Keywords: Amiidae, Calamopleurus, Early Cretaceous, Brazil
