Abstract So far, there are at least 22 species of fossil turtles formally described for Brazil, with the Araripe Basin being the second largest in Mesozoic diversity with five species, losing only to the Bauru Group, with six species. The material presented here refers to three fossil turtles (DGEO-CTG-UFPE 8470, DGEO-CTG-UFPE 8471, DGEO-CTG-UFPE ...

Abstract This work presents the osteological description and taxonomic position of new mawsoniid fossils from the Early Cretaceous Romualdo Formation (Aptian-Albian) of the Araripe Basin, in Pernmabuco, Brazil. The fossils were collected in the municipalities of Araripina, Exu, Ipubi and a new occurrence is registered in the municipality of Ouricuri.

A new fossil caridean shrimp, Kellnerius jamacaruensis n. gen. n. sp., of the early Cretaceous (Albian) from the Romualdo Formation, Araripe Basin, northeastern Brazil is described and illustrated. The new species is compared to known fossil palaemonids found in Brazil. Kellnerius jamacaruensis n. gen. n. sp.

Abstract Because of its fossil abundance and exceptional preservation, the Romualdo Formation of the Santana Group has become a famous lithostratigraphic unit of the Araripe Basin. In the past decades, much research has been conducted on the vertebrates of this unit, especially fish and pterosaurs, based mainly on museum collections ...

Mercury (Hg) biomagnification values tend to reflect relationships between species in the trophic web the larger the value, the higher their position in the web. Here we present the first attempt to reconstruct paleo-trophic linkages during the onset of the Romualdo Formation in the Araripe Basin (Northeastern Brazil), based on analyses of Hg ...
