Redescription of Tijubina pontei, an Early Cretaceous lizard (Reptilia; Squamata) from the Crato Formation of Brazil

Anais da Academia Brasileira de Ciências, 2012
The record of Gondwanan Mesozoic lizards is very poor. Among the few species described for this region there is Tijubina pontei, an Early Cretaceous lizard from the Crato Formation (late Aptian) of northeast Brazil.

Evolution of reproductive strategies in dictyopteran insects—clues from ovipositor morphology of extinct roachoids [PDF]

Acta Palaeontologica Polonica, 2018
Dictyoptera, which comprises cockroaches, termites and mantids, is a quite successful group of insects in evolutionary terms with a long fossil record—roachoid insects were already abundant 315 million years ago in the Carboniferous forests.

Geometric Morphometrics Reveal Body Shape Variation in Freshwater Shrimps of the Genus Macrobrachium Lacking a Mandibular Palp (Formerly Pseudopalaemon Sollaud, 1911) (Decapoda: Palaemonidae)

Acta Zoologica, EarlyView.
ABSTRACT Shape variation in the cephalothorax of Macrobrachium species without mandibular palp using geometric morphometrics was used as a tool to support species differentiation and propose new diagnostic characters for taxonomic identification.

Contrasting Approaches in the Implementation of GRADE Methodology in Guidelines for Haemophilia and Von Willebrand Disease

Haemophilia, EarlyView.
ABSTRACT Introduction The 2024 ISTH clinical practice guideline (CPG) for treatment of congenital haemophilia, the NBDF‐McMaster Guideline on Care Models for Haemophilia Management, and ASH ISTH NBDF WFH guidelines on the diagnosis and management of VWD all utilised GRADE methodology.

Paleometric approaches reveal striking differences in the insect fossilization of two Mesozoic Konservat-Lagerstätten

Frontiers in Ecology and Evolution
The Crato Formation (Lower Cretaceous, Brazil) is a Konservat-Lagerstätte preserving a great number of exceptionally well-preserved insects. Here, we sought to explore the preservational modes of two abundant aquatic and terrestrial groups of this unit ...

Inside a duck‐billed dinosaur: Vertebral bone microstructure of Huallasaurus (Hadrosauridae), Upper Cretaceous of Patagonia

The Anatomical Record, Volume 309, Issue 7, Page 1702-1712, July 2026.
Abstract Dinosaurs evolved a unique respiratory system with air sacs that contributed to their evolutionary success. Postcranial skeletal pneumaticity (PSP) has been used to infer the presence of air sac systems in some fossil archosaurs. While unambiguous evidence of PSP is well documented in pterosaurs and post‐Carnian saurischians, it remains absent

Pilot Study on Fingerprinting the Isotopic Signatures of Fossiliferous Limestones as a Tool for Forensic Investigation of Fossil Trafficking (Cretaceous Crato Formation, Brazil)

Geosciences
Unauthorized fossil trafficking violates national legislation and deprives cultural and natural heritage. This study proposes a pilot method to fingerprint the origin of fossils by characterizing the carbon and oxygen stable isotope signatures of fossil ...

Assessment of the Acute Toxicity and Anxiolytic‐Like Effect of α‐Humulene in Adult Zebrafish (Danio rerio)

Chemistry &Biodiversity, Volume 23, Issue 7, July 2026.
The monocyclic sesquiterpene α‐humulene elicited a significant anxiolytic‐like behavior in adult zebrafish and no observable acute toxicity. Pharmacological dissection suggested that this effect is independent of the benzodiazepine (BZD) binding site on the gamma‐aminobutyric acid (GABA) type A receptor (GABAAR), but it depends on the serotonin type 3 ...

Unearthing Mesozoic beetles through micro‐computed tomography: A new family of Archostemata and the first representatives of Ommatidae and †Notocupes from the Crato Formation

Systematic Entomology, Volume 51, Issue 3, July‐September 2026.
First formally described Archostemata beetles from the Lower Cretaceous Crato Formation are reported, representing the earliest records of the suborder from western Gondwana. Micro‐computed tomography enabled three‐dimensional reconstruction of partially exposed fossils, revealing previously hidden dorsal and ventral morphological characters relevant ...
