-Twenty-two species of the bivalve order Pholadomyida, belonging to six genera and seven subgenera of the families Pholadomyidae, Pleuromyidae and Poromyidae are described from the Cenomanian-Coniacian Cotinguiba Formation of the Sergipe Basin, north-eastern Brazil. Eleven species, Pholadomya (Ph.) cf. agrioensis Weaver, Ph. RESUMO -Vinte e duas espécies de biválvios da ordem Pholadomyida pertencentes a seis gêneros e sete subgêneros das famílias Pholadomyidae, Pleuromyidae e Poromyidae são descritas do Cenomaniano-Coniaciano da Formação Cotinguiba, bacia de Sergipe, nordeste do Brasil. Onze espécies são registradas na bacia pela primeira vez:(Sergipemya) gigantea (J. Sowerby). Foi proposto o novo subgênero Sergipemya do gênero Liopistha, família Poromyidae, com base em caracteres morfológicos tais como: valvas grandes e fortemente infl adas, costelas comarginais numerosas, uma área umbonal anterior bem desenvolvida e arredondada margeando uma depressão profunda sobre a parte anterior, e a presença de dois dentes cardinais diferentes com um soquete cardinal em forma de ranhura na valva esquerda. A fauna de pholadomyideos de Sergipe assemelha-se fortemente àquela de outras regiões tetianas no oeste e no sul da Europa, no norte e oeste da África e no Oriente Médio. Os padrões de distribuição dos táxons foram infl uenciados provavelmente por correntes no sentido leste-oeste. Os pholadomyideos tetianos da parte sul alcançaram a África ocidental e o nordeste da América do Sul pela via transsaariana.Palavras-chave: Pholadomyida, taxonomia, paleobiogeografi a, Cretáceo, Formação Cotinguiba, Brasil.

“…Folded shells are commonly observed in Cretaceous limestones of Brazil (e.g., SEELING & BENGTSON, 1999) and are usually referred to Lopha-type shells ( .G-H). The calcitic nature of these "fragments" most definitively disqualifies them to be ascribed to algae; conversely, the foliated structure of their folded calcitic layers as observed in thin sections is typically that found in mollusc shells.…”

Abstract:Out of the few records of rudists from the Cretaceous strata of the South Atlantic coastal basins only two refer to Brazilian localities. However, petrographic analyses demonstrate that these shells should be assigned to Ostreids or to Pycnodontids rather than to Rudistids. More specifically, the domain considered herein, north of the Río Grande Rise -Walvis Ridge barrier, was part of the warmwater "tropical" realm, but it was not part of the Mesogean domain because both Rudistids and Orbitolinas are missing. In addition, the scarcity of corals leads us to ascribe the taphonomic assemblage to the Chloralgal facies. Neither generalized hypersalinity or extreme sea-water temperatures seem to account for these biotic peculiarities. Instead, our alternative hypothesis favors the driving role played by oceanic circulation in the dispersal of the benthic organisms.Key Words: Rudists; Ostreids; Pycnodontids; corals; Orbitolinids; calcareous algae; Cretaceous; Albian; Cenomanian; South Atlantic; Tethys; Mesogea; Chloralgal; paleobiogeography. Résumé : Fin d'un mythe géologique moderne : il n'y a pas de rudistes au Brésil ! et ses implications paléobiogéographiques.-Parmi les quelques signalements de rudistes dans les séries crétacées des bassins côtiers de l'Océan Atlantique Sud, deux seulement correspondent à des sites brésiliens. Toutefois, les analyses pétrographiques montrent que ces coquilles ne sauraient être attribuées à des rudistes mais plutôt à des Ostréidés ou à des Pycnodontidés. Plus spécifiquement, les régions situées au N de la barrière Rio Grande Rise-Walvis appartenaient au domaine à eaux "tropicales" chaudes, mais pas au domaine mésogéen parce que rudistes et orbitolines y font défaut. De plus, la rareté des coraux nous a conduit à attribuer l'association taphonomique au faciès Chloralgal. Ni une hypersalinité généralisée, ni des températures particulièrement élevées de l'eau de mer ne semblent rendre compte de ces particularités biotiques. Au lieu de cela, notre hypothèse alternative favorise le rôle moteur joué par la circulation océanique dans la dispersion des organismes benthiques.
