Paleoecology and paleoenvironments of Permian bivalves of the Serra Alta Formation, Brazil: Ordinary suspension feeders or Late Paleozoic Gondwana seep organisms?
(Journal Of South American Earth Sciences, 2017-08-01) [Artigo]
This is the first record of a Permian seep deposit and an associated, morphologically bizarre, bivalve-dominated fauna from the Passa Dois Group, Parana Basin, Brazil. Shales of the outer-shelf facies of the Serra Alta ...
Permian endemic bivalves of the Irati anoxic event, Parana Basin, Brazil: Taphonomical, paleogeographical and evolutionary implications
(Palaeogeography Palaeoclimatology Palaeoecology, 2017-03-01) [Artigo]
Anoxic to dysoxic conditions must have existed in the Parana Basin during the deposition of the Permian oil-bearing shales of the Irati Formation, reflecting the marine isolation of the basin from the Panthalassic Ocean. ...
Upper Aptian mixed carbonate-siliciclastic sequences from Tucano Basin, Northeastern Brazil: Implications for paleogeographic reconstructions following Gondwana break-up
(Cretaceous Research, 2016-12-01) [Artigo]
The evolution of the Cretaceous basins of the Brazilian northeastern hinterland was associated with the Gondwana rifting and opening of the South Atlantic Ocean. The first marine ingression in northeastern Brazil occurred ...
