A eudicot leaf from the Lower Cretaceous (Aptian, Araripe Basin) Crato Konservat‐Lagerstätte

American Journal of Botany, 2021
AbstractPremiseThe Crato Konservat‐Lagerstätte in Brazil preserves an exceptionally rich assemblage of plant macrofossils from the Early Cretaceous (late Aptian), including rare early angiosperm fossils related to Nymphaeales, monocots, and magnoliids, and a variety of angiosperms of uncertain affinities.

Araripe Basin: A Major Geodiversity Hotspot in Brazil

Geoheritage, 2017
In addition to a Fossil-Lagerstatte of international significance for the Lower Cretaceous, the Araripe basin is one of the richest and most threatened reservoirs of geodiversity in Brazil. Far from being limited to its palaeontological heritage, the major importance of geodiversity in the Araripe region is also related to high levels of ...

Natural Fracture Characterization in Aptian Carbonates, Araripe Basin, NE Brazil

Proceedings, 2014
This paper addresses fracture characterization in an Aptian laminated limestone, the Crato Formation, cropping out in the Araripe Basin (NE, Brazil) using a scanline technique. This unit has been used as a geological analogue of buried naturally fractured carbonate reservoirs.

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.
