“…Non-metric multidimensional scaling (nMDS) was used to investigate biogeographic relationships. In agreement with Kiessling et al (2011), although metric multidimensional scaling (MDS) makes fewer assumptions on the nature of the data, it always fi nds a globally optimum solution, whereas non-metric scaling iteratively seeks the best solution, which may just represent a local optimum. For details about the mechanism and utility of the latter multivariate techniques, see Huntley (2011, p. 28-37).…”

-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.

“…Pleuronectites has a time range from the Middle to Late Triassic (Anisian to Carnian, see Hayami 1975;Waller 2006) and an apparently wide geographical distribution in the Tethys and circum-Pacific areas ( fig. 3), but this was subsequently referred to Eopecten, see Stefanini (1939), Cox (1965) and Kiessling et al (2011). Consequently, if Pleuronectites and Huncalotis are phylogenetically related, it is evident that there is a huge time gap between them (Carnian-Tithonian, i.e.…”

The extensive outcrops of the Late Jurassic-Early Cretaceous Vaca Muerta Formation black shales and marls in the Neuquén Basin have yielded very few bivalves, and these are not well known. The material described here was collected in central Neuquén, from late Tithonian calcareous levels within the black shales, between beds with Substeueroceras sp. and with Argentiniceras noduliferum (Steuer). The material is referred to the new genus Huncalotis and to the new species H. millaini. The strongly inequivalve shells, the ligamental area with a triangular slightly prosocline resilifer, the right valve with ctenolium and a very deep byssal notch, and the lack of radial ornamentation make the shell of this new genus strikingly similar to the Triassic pectinid Pleuronectites. This resemblance may be due to either phylogenetic relationships or convergence. Obliquipecten peruanum Rivera from central Peru is tentatively referred to Huncalotis. The Neuquén specimens are found in two main preservation types. Most of the material occurs in shell pavements, with equally abundant right and left valves and wide size range, within ''beef'' or ''sandwich concretions''. These specimens are commonly complete but disarticulated, and show radial fractures orientated at right angles to the shell margins. A few specimens were found on the outside of large calcareous concretions within black shales; these are often articulated, complete shells, which preserve the original convexity of the valves. In some cases these articulated shells seem to be associated with large ammonite shells, suggesting an epibyssate (possibly also pseudoplanktonic) lifestyle.
