A lizard from the Early Cretaceous Crato Formation, Araripe Basin, Brazil

Neues Jahrbuch für Geologie und Paläontologie - Monatshefte, 1998
A lizard from the Early Cretaceous Crato Formation of Brazil is the first from this Formation and one of the earliest recorded lizards from South America. The specimen represents a very young individual, probably recently hatched. The lower jaws are characterised by an elongated dorsal ramus of the dentary which replaces the surangular along much of ...

Biostratigraphy of Lower Cretaceous microfossils from the Araripe basin, northeastern Brazil

Geobios, 2002
Abstract A biostratigraphic study was carried out in the Lower Cretaceous Araripe basin, northeastern Brazil, allowing the recognition of several chronostratigraphic units: the Dom Joao (Jurassic?–Lower Cretaceous?), the Rio da Serra (Neocomian) and the Alagoas (Aptian/Albian) local stages.

Fire in the paradise: evidence of repeated palaeo-wildfires from the Araripe Fossil Lagerstätte (Araripe Basin, Aptian-Albian), Northeast Brazil

Palaeobiodiversity and Palaeoenvironments, 2019
Reports on Cretaceous charcoals are relatively common on a global scale and have been increasing in recent years. Fossil charcoal from the Early Cretaceous mostly belongs to conifers (and other gymnosperms) and ferns whereas angiosperms become more common only during the Late Cretaceous.

Fossil‐Bearing Concretions of the Araripe Basin Accumulated During Oceanic Anoxic Event 1b

Paleoceanography and Paleoclimatology, 2023
AbstractFossils from the Araripe Basin (northeastern Brazil) are known for their remarkable preservation of vertebrates and invertebrates, even including soft tissues. They occur in carbonate concretions within organic carbon‐rich strata assigned to the Romualdo Formation.

Description and ontogeny of Pattersoncypris minima sp. nov. (Crustacea: Ostracoda), Araripe Basin, Northeast Brazil

Zootaxa, 2020
Representatives of the Class Ostracoda are widely used as tools in applied paleoecological and biostratigraphical studies in all continents. In the Araripe Basin, located in the northeastern of Brazil, the Romualdo Formation is one of the most studied, not only for the preservation but also for the abundance of its fossils.

Petrophysics and Petrography of Aptian Tight Carbonate Reservoir, Araripe Basin, NE Brazil

78th EAGE Conference and Exhibition 2016, 2016
In recent decades, the exploitation of hydrocarbon reserves in carbonate reservoirs has motivated increasing numbers of investigations into their petrophysical characteristics due to their importance in fluid flow predictions. For tight reservoirs that are mainly composed of carbonate and fine-grained rocks, the determination of the petrophysical and ...

Plant–arthropod interaction in the Early Cretaceous (Berriasian) of the Araripe Basin, Brazil

Journal of South American Earth Sciences, 2009
Abstract Plant–arthropod interactions provide the first relevant data for addressing evidence of phytophagy for an assemblage of coniferous silicified woods from the pre-rift phase in the Araripe Basin, Brazil. A complex system of borings, sometimes filled with small, oval to hexagonal coprolites, allow inferences to be made about the activities of ...
