Towards an actualistic view of the Crato Konservat-Lagersta & uml;tte paleoenvironment: A new hypothesis as an Early Cretaceous (Aptian) equatorial and semi-arid wetland
(Elsevier B.V., 2021-05-01)
An alternative hypothesis concerning the paleoecological and paleoenvironmental depositional conditions of the Crato Konservat-Lagersta?tte (CKL), Crato Formation, Aptian, NE Brazil, one of the most extraordinary Gondwana ...
Mixed siliciclastic-carbonate sedimentation in an evolving epicontinental sea: Aptian record of marginal marine settings in the interior basins of north-eastern Brazil
(Wiley-Blackwell, 2021-03-15)
The Aptian evaporitic transitional sequence (sag phase) of the Brazilian marginal basins records the first connection between the Central and South Atlantic oceans in the equatorial area. During this phase, lacustrine ...
Deciphering the preservation of fossil insects: a case study from the Crato Member, Early Cretaceous of Brazil
(Peerj Inc, 2016-12-21)
Exceptionally well-preserved three-dimensional insects with fine details and even labile tissues are ubiquitous in the Crato Member Konservat Lagerstatte (northeastern Brazil). Here we investigate the preservational pathways ...
Abordagem multi-indicadores do sistema misto carbonático-siliciclástico da Formação Crato: evolução sedimentar, paleogeografia e tectônica
(Universidade Estadual Paulista (Unesp), 2019-08-02)
A megassequência evaporítica transicional de idade aptiana constitui importante registro da abertura da margem equatorial brasileira, das primeiras conexões entre as águas dos oceanos Atlântico Sul e Central, e de depósitos ...
Stromatolites from the Aptian Crato Formation, a hypersaline lake system in the Araripe Basin, northeastern Brazil
(Springer, 2017-01-01)
The origin of the Cretaceous laminites of the Crato Formation, Araripe Basin, northeastern Brazil, has been intensely debated since the beginning of the last century. The monotonous, up to 10-m-thick succession composed ...
The transgressive-regressive cycle of the Romualdo Formation (Araripe Basin): Sedimentary archive of the Early Cretaceous marine ingression in the interior of Northeast Brazil
(2017-08-15)
Geologic events related to the opening of the South Atlantic Ocean deeply influenced the sedimentary record of the Araripe Basin. As consequence, upper stratigraphic units of the basin record a marine ingression in ...
Earliest Tuatara relative (Lepidosauria: Sphenodontinae) from Southern ContinentsEl más temprano pariente del Tuatara (Lepidosauria: Sphenodontinae) de los continentes australes
(Asociación Paleontológica Argentina, 2021-09)
The New Zealand tuatara (Sphenodon) is the sole surviving rhynchocephalian of a once thriving group across Pangea during early Mesozoic times. Outside New Zealand, close relatives of the tuatara (sphenodontines) are known ...

The origin of the Cretaceous laminites of the Crato Formation, Araripe Basin, northeastern Brazil, has been intensely debated since the beginning of the last century. The monotonous, up to 10-m-thick succession composed ...
Marine or freshwater? Accessing the paleoenvironmental parameters of the Caldas Bed, a key marker bed in the Crato Formation (Araripe Basin, NE Brazil)
(Sociedade Brasileira de Geologia, 2020-12-21)
The Aptian Crato Formation is world renowned for its well-preserved fossils in microbially-induced laminated limestones, which are regarded as one of the main Cretaceous Konservat-Lagerstätte of the geological record. ...
