Morphological plasticity in the dentition of the lungfish Gnathorhiza from the Permian of Brazil: A population‐level geometric morphometric analysis

The Anatomical Record, EarlyView.
Abstract Dental plates are pivotal in the lungfish paleontological record, constituting highly mineralized structures resilient to diagenetic processes. This study provides a detailed description and quantitative shape analysis of 95 newly discovered Gnathorhiza sp. dental plates from the Middle–Late Permian Corumbataí Formation, Brazil.

Spatio‐Temporal Assessment of the Complementarity Between Hydroelectric, Wind and Solar Energy Sources for Northeastern Brazil

International Journal of Climatology, EarlyView.
Using 24 years of climate and hydrological data, this study quantifies the spatiotemporal complementarity among the water availability of the Sobradinho reservoir, wind and solar in Northeastern Brazil. The integration of hierarchical clustering and compromise programming reveals how seasonal variability and reservoir dynamics interact with atmospheric

The Earliest Feathers from the Lower Cretaceous Dabeigou Formation of North Hebei: Implications for the Early Evolution of the Jehol Biota

Integrative Zoology, EarlyView.
This study reports two isolated feather fossils from the Lower Cretaceous Dabeigou Formation in northeastern China. Morphological analyses identified them as the earliest known feathered theropods (potentially including avian) in the Jehol Biota. This finding reveals a complex ecosystem at the dawn of the Jehol Biota, bridging the temporal and faunal ...

Shrimps from the Santana Group (Cretaceous: Albian): new species (Crustacea: Decapoda: Dendrobranchiata) and new record (Crustacea: Decapoda: Caridea)

Anais da Academia Brasileira de Ciências, 2014
The fossil shrimp Araripenaeus timidus n. gen. n. sp. is the first fossil Penaeoidea from Brazil. Here, we describe, illustrate and compare it with Paleomattea deliciosa, a fossil Sergestoidea (Dendrobranchiata) previously described from the same region.

Lantana delicata (Verbenaceae), a New Species From Brazil, and Additional Updates Within the Genus

Feddes Repertorium, Volume 137, Issue 3, September 2026.
ABSTRACT In this study, we present some novelties in Lantana, a taxonomically complex genus of Verbenaceae. These include (1) the description of L. delicata, a new species from Brazil; (2) the lectotypification of the name L. magnibracteata; and (3) the recognition of L. fucata f. albiflora, previously regarded as a synonym of L.
