On Northeast Brazil Orographic Enhanced Rainfall and Monsoon Dynamics

International Journal of Climatology, Volume 45, Issue 10, August 2025.
We provide an updated rainfall climatology (1990–2020) for Northeast Brazil which discusses the role of orographically enhanced rainfall and monsoon dynamics on this climate system. Our work presents strong evidence that this continental‐scale region is under a more extensive influence of the South American Monsoon System than previously described ...

A new antshrike (Aves: Thamnophilidae) endemic to the Caatinga and the role of climate oscillations and drainage shift in shaping cryptic diversity of Neotropical seasonal dry forests

Zoologica Scripta, Volume 53, Issue 5, Page 487-508, September 2024.
Abstract The Caatinga is the largest patch of Seasonal Dry Tropical Forest in the Neotropics, located in northeastern Brazil and characterized mainly by deciduous vegetation and extreme rainfall seasonality. It has historically been treated as a biologically impoverished domain, but recent studies uncovered new diversification patterns and several new ...

New detrital petrographic and thermochronologic constraints on the Late Cretaceous–Neogene erosional history of the equatorial margin of Brazil: Implications for the surface evolution of a complex rift margin

Basin Research, Volume 36, Issue 1, January–February 2024.
Since the Late Cretaceous, the equatorial margin of Brazil has undergone a rift phase, with the erosion of a moderate rift escarpment, a Late Cretaceous–Paleogene post‐rift phase, with major drainage reorganization and significant vertical erosion, and a Late Oligocene‐to‐Recent post‐rift phase, with moderate vertical erosion and river headwater ...

First report of pterosaur remains from the Lower Cretaceous Quiricó Formation, São Francisco Basin (Minas Gerais), Brazil [PDF]

Anais da Academia Brasileira de Ciências
The record of pterosaur fossils in Brazil is significant, however, it remains limited to a few sedimentary basins from the Cretaceous period. This study describes an isolated pterosaur tooth assigned to Ornithocheiriformes, collected from the Quiricó ...

New evidence of feathers in the Crato Formation supporting a reappraisal on the presence of Aves

Anais da Academia Brasileira de Ciências, 2011
The preservation of delicate structures such as feathers is very rare in the paleontological record, due to the fragility of their components. Fossil feathers have been reported from approximately 50 deposits around the world, from the Late Jurassic to ...
