We described herein †Ellimma longipectoralis sp. nov., a new paraclupeid ﬁsh from the Aptian laminites of the pre-salt section in the Barra Velha Formation, Santos Basin, southeastern Brazil. This new species is represented by a single articulated specimen with elongate body and expanded pectoral region. It diﬀers from the other nominal species of...
Large oil accumulation discoveries in the last decade in the pre-salt rock succession off the Brazilian coast aroused renewed interest in carbonate reservoirs, prompting several studies aiming at unravelling the conditions of formation of these rocks. Despite that, there are still many gaps in the knowledge concerning environmental conditions of th...
The Sergipe-Alagoas Basin has one of the most complete, exposed lithological successions of the Cretaceous period in the continental margin of Brazil. It captures several phases of the evolution of the South Atlantic Ocean, including rift, gulf and drift. The upper Aptian–Albian Riachuelo Formation corresponds to the first stages of the southern pr...
The non-marine Lower Cretaceous ostracod genus Kegelina new genus (Cypridoidea, Cyprideidae) is known from South America (Bahia state, eastern Brazil), West Africa (Gabon and 'Congo'), and North America (Montana, Idaho and Wyoming, U.S.A.). It comprises five species: Kegelina anomala (Peck, 1941) new combination, Kegelina armata (Krommelbein, 1962)...
The susceptibility of ostracoda from different habitats to environmental and climatic change, form distinct assemblages that are useful both in continental and marine paleoenvironmental reconstructions. Ostracod assemblages recovered from late Pleistocene-Holocene carbonatic mud, of piston core GL-451 in the Campos Basin, contains mixed assemblages...
The taxonomic status of the Lower Cretaceous non-marine ostracode genera Hourcqia Krommelbein and Pattersoncypris Bate is discussed. From a detailed analysis of the type species of these genera, and several other species attributed to them, it was possible to conclude that both genera are invalid. Hourcqia africana Krommelbein, the type species of...
A small clupeomorph fish, Ellimmichthys maceioensis n. sp., is described and Dastilbe crandalli JORDAN, is recorded from the Aptian-Albian of the Macció Formation in the Alagoas Basin, NE Brazil. E. maceioensis shares a number of features with other paraclupeines among which are shape and ornamentation of the dorsal scutes. However, meristic variat...
To uncover the conditions that favoured the formation of carbonate deposits and associated rocks in lacustrine environments during the rifting of the southern Gondwana continent.
It aims to study in detail the taxonomy of ostracode associations recovered from Riachuelo Formation, Sergipe-Alagoas basin, State of Sergipe, northeastern Brazil. Its objectives are to extend the knowledge about the biodiversity, biostratigraphy and paleoecology of the Aptian-Albian of the referred basin. It will give new elements to establish the relationship of the Alagoas Stage in Brazil with the international Aptian and Albian stages, especially with chronocorrelate layers from other Brazilian and West African marginal basins.
