crajiv Posted March 27, 2017 Share Posted March 27, 2017 Scales and form look similar to Rhacolepis Buccalis, but puzzled by the rather elongated slender body Thanks Link to comment Share on other sites More sharing options...
Fossildude19 Posted March 27, 2017 Share Posted March 27, 2017 Looks more like a Vinctifer comptoni, to me. Looks like a ventral presentation. The elongated scales on the sides are a distinguishing feature.

oilshale Posted March 28, 2017 Share Posted March 28, 2017 Tim is right (as always ) - this is a Vinctifer comptoni. Thomas Be not ashamed of mistakes and thus make them crimes (Confucius, 551 BC - 479 BC). Link to comment Share on other sites More sharing options...
abyssunder Posted March 28, 2017 Share Posted March 28, 2017 Yup, Tim is right! Excellent! I agree about V. comptoni. just to cite from Paulo M. Brito, Yoshitaka Yabumoto. 2011. An updated review of the fish faunas from the Crato and Santana formations in Brazil, a close relationship to the Tethys fauna. Bull. Kitakyushu Mus. Nat. Hist. Hum. Hist., Ser. A, 9: 107–136 : " There are two aspidorhynchids in the Araripe Basin: Vinctifer comptoni (Agassiz, 1841) (Fig. 17) from the Santana Formation, and a new species of Belonostomus (Fig. 18) from the Crato Formation. Vinctifer and Belonostomus are two of four genera comprising the Aspidorhynchidae, a widely distributed Mesozoic family (the other two genera are Aspidorhynchus and Richmondichthys; the latter is probably a synonym of Vinctifer) of highly elongate predatory fishes. The aspidorhynchids are easily recognized by the presence of a long rostrum formed by the premaxillae; presence of a predentary on the lower jaw; deep elongate flank scales; and posteriorly located dorsal and anal fins.Vinctifer is one of the most common species in the Santana Formation, where it is known from specimens of between 50 and 900 mm total length (Brito, 1997). Vinctifer comptoni is a typical southern Tethyan genus, also known in other northeastern Brazilian basins (e.g., Parnaíba, Sergipe-Alagoas), as well as in the Aptian-Albian of Venezuela, Colombia, Mexico and Antarctica (Moody and Maisey, 1994; Schultze and Stöhr, 1996; Applegate, 1996; Brito, 1997) and probably also the Neocomian of Rio Muni, Equatorial Guinea (Taverne, 1969). Two nominal species are recognised: Vinctifer comptoni (the type species), and Vinctifer longirostris, known only from the Tucano Basin (also in northeastern Brazil). " comparative pictures: " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.
