Aptian Shell Beds From the Romualdo Formation (Araripe Basin): Implications for Paleoenvironment and Paleogeographical Reconstruction of the Northeast of Brazil

Sedimentary Geology, 2021
The Aptian Romualdo Formation in the Araripe Basin represents the establishment of an epeiric sea in the Brazilian Northeast during the Early Cretaceous. This unit is composed by a succession of limestones, shales, sandstones, and coquinas, which constitute shell beds near the top.

Abstract A pteranodontoid pterosaur with anhanguerid affinities (MPSC R 1935) from the Romualdo Formation (Lower Cretaceous, Aptian), is described here and provides one of the few cases where the ontogenetic stage is established by comparison of skeletal fusion and detailed osteohistological analyses. The specimen comes from the Baixa Grande locality

New occurrences of fossil Testudines of the Romualdo Formation, Aptian-Albian of the Araripe Basin, Pernambuco, Northeast Brazil

Journal of South American Earth Sciences, 2019
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 ...

CONTROLLED EXCAVATIONS IN THE ROMUALDO FORMATION LAGERSTÄTTE (ARARIPE BASIN, BRAZIL) AND PTEROSAUR DIVERSITY: REMARKS BASED ON NEW FINDINGS

PALAIOS, 2011
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 ...

Reconstructing paleo-trophic relationships on the Brazilian Romualdo Formation (Early Cretaceous) through mercury analysis in fossils

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 ...
