The Anatomical Record, EarlyView.Abstract The Upper Cretaceous São José do Rio Preto Formation (Bauru Group, southeastern Brazil) has yielded a fragmentary but taxonomically diverse record of titanosaur sauropods, although elements from cervical series remain scarce. Here, we describe a nearly complete sauropod axis from the Vila Ventura Paleontological Area, representing an uncommon ...

The Anatomical Record, EarlyView.Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to

Osteohistology of two phorusrhacids reveals uninterrupted growth strategy
The Anatomical Record, EarlyView.Abstract Phorusrhacidae were apex predators that primarily dominated South America ecosystems for at least 40 million years with their imposing size and predatory lifestyle—yet some aspects of their biology remain poorly understood. Osteohistology is a tool for understanding growth dynamics and biomechanical adaptations.

Publicación Electrónica de la Asociación Paleontológica Argentina, 2019 In 1887 Carlos Ameghino carried out the earliest extensive exploration of the fossiliferous localities along the Río Santa Cruz (Patagonia). His brother Florentino erected more than 100 vertebrate species based on the remains that Carlos recovered.

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 1, January 2026.ABSTRACT Climate change significantly threatens biodiversity, particularly in freshwater ecosystems, which host many endemic and threatened species. Among them, aeglids stand out as strictly endemic, ecologically important and highly threatened crustaceans, making them a relevant model for investigating the impacts of climate change on aquatic ...
