A New Genus and Species of †Cladocyclidae (Teleostei: †Ichthyodectiformes) from the Lower Cretaceous “Batateira Beds”, Barbalha Formation, Araripe Basin: The First Vertebrate Record in a Still Poorly Explored Fossil Site

Diversity, 2023
The Mesozoic Teleostei †Ichthyodectiformes presents a widespread distribution in marine brackish and freshwater deposits worldwide. The Brazilian fossil record of this group is represented by five nominal genera distributed exclusively in the sedimentary

Hyperdominant Trees Reveal Savanna Vulnerability Under Climate Change. [PDF]

Glob Chang Biol
The Brazilian Cerrado's forest structure relies disproportionately on just 30 hyperdominant tree species, which represent 50% of all individuals despite accounting for only 2% of species richness. This study evaluates their vulnerability under climate change scenarios for 2100.

Stratigraphic Relations of the Ipubi Formation: Siliciclastic-Evaporitic Succession of the Araripe Basin [PDF]

Anais da Academia Brasileira de Ciências, 2018
The Ipubi Formation represents the Aptian-Albian siliciclastic-evaporitic succession of Araripe Basin, NE Brazil. This succession comprises siliciclastic rocks (bituminous shales and claystones) and evaporites (gypsum and secondary anhydrite) and represents part of the lacustrine-shallow marine post-rift phase I.

For your eyes too: a new set of images of biological materials from the scientific commissioning of the MOGNO beamline at Sirius. [PDF]

J Synchrotron Radiat
From whole specimens to histological level reconstructions, images derived from 3D synchrotron‐based microtomography (SR‐microCT) have emerged as a tool that is revolutionizing a wide range of biological research. This paper presents the first commissioning results from experiments to image the anatomy of small animals and specimens from zooarchaeology

Analogue modelling of basin inversion: the role of oblique kinematics and implications for the Araripe Basin (Brazil)

, 2022
Abstract. Basin inversion is a process that takes place when a sedimentary basin is subjected to compressional stresses and may result in the reactivation of pre-existing faults and/or the localization of deformation along new reverse faults. The Araripe Basin (NE Brazil) is an example of a Cretaceous intracontinental aborted rift with its sedimentary ...

A gestão ambiental nas paisagens da bacia do Araripe no Estado do Ceará

Confins, 2016
The Araripe basin is considered the largest sedimentary basin in northeastern Brazil, being extremely important for the state of Ceará, due to occupancy, which is directly linked to natural potential.
