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.

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

Fossil Megaloptera (Insecta: Neuropterida) from the Lower Cretaceous Crato Formation of Brazil

Zootaxa, 2016
Two new genera and species of Megaloptera are described from the Lower Cretaceous Crato Formation of Brazil. Cratocorydalopsis brasiliensis gen. et sp. nov. and Lithocorydalus fuscata gen. et sp. nov. are both placed within the family Corydalidae. The specimens represent the first Cretaceous examples of adult megalopteran body fossils not preserved in ...

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 ...

Crocodilians of the Crato Formation: evidence for enigmatic species

2007
Crocodilians are extremely rare in the Crato Formation, and most of the material that has been collected is fragmentary or badly preserved. Only two species are represented, both of which are enigmatic concerning both their preservation and anatomy.

Araripia florifera, a magnoliid angiosperm from the Lower Cretaceous Crato Formation (Brazil)

Review of Palaeobotany and Palynology, 2003
Abstract The Lower Cretaceous (Aptian or possibly Albian) Crato Formation of Brazil contains a variety of angiosperm impression fossils, mainly detached leaves, but also remains with various parts in organic connection. Among these more complete fossils are axes with attached leaves and sometimes also with reproductive structures. Araripia florifera

Early Angiosperms from the Lower Cretaceous Crato Formation (Brazil), a Preliminary Report

International Journal of Plant Sciences, 2000
Early Cretaceous angiosperm remains from the Gondwana Continent were hitherto very rare. The Aptian or Albian Crato Formation (Brazil) contains various angiosperm fossils, mainly detached leaves, but there are also impression fossils with organically connected parts.
