Ostracods from the Barbalha and Crato formations, Aptian of the Araripe Basin, northeast Brazil

Zootaxa, 2023
Ostracods have been widely used for biostratigraphic and paleoenvironmental purposes for the Lower Cretaceous deposits of northeastern interior Brazilian basins. The ostracods of the Romualdo and Crato formations of the Araripe Basin are particularly well known; however, the ones from the underlying Barbalha Formation are less so.

Introduction to the Crato Formation

2007
The Crato Formation takes its name from the university town of Crato, Ceara, situated in a forested cirque in the north central part of the Chapada do Araripe, a large tableland in north-eastern Brazil (Plate 1a). Its outcrop pattern forms a narrow strip along the flanks of the plateau, and is also present as a few isolated outliers to the south of the

Stratigraphy of the Crato Formation

2007
Introduction The Crato Formation comprises a series of laminated limestones inter-bedded with sandstones, marls and clays, sandwiched between a highly variable sequence of strata in the mainly Mesozoic Araripe Basin. Its distribution has not been completely mapped as an integral stratigraphic unit, although some beds of limestone were mapped by the ...

Spectroscopic studies of wood fossils from the Crato Formation, Cretaceous Period

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2013
In this work we study two types of wood fossils (Gymnosperms, Araucariaceae) from the Crato Formation of Araripe Basin in Brazil, from the Cretaceous Period. The samples were characterized by Raman and infrared spectroscopies, X-ray diffraction and scanning electron microscopy. The results obtained by different techniques showed that although the rocks

A new scoliid wasp in the Early Cretaceous Crato Formation in Brazil (Hymenoptera: Scoliidae)

Zootaxa, 2013
The new genus and species of scoliid wasp Araripescolia magnifica Nel, Escuillie & Garrouste, gen. et sp. nov. is described from the Early Cretaceous Crato formation in Brazil. It seems to be more closely related to the modern Campsomerinae than to the other Cretaceous Scoliidae: Archaeoscoliinae and Proscoliinae.
