Extinct Pseudopus pannonicus, the largest known anguid lizard from Central Europe, was recently revised. Using high-resolution imaging, the osteology of specimens was detailed, their identification updated, and biogeographic implications discussed. Phylogenetic analysis confirmed P. pannonicus as a distinct member of the Pseudopus clade.

A new hypothesis for the early evolution of vertebrate air-breathing behaviors by Kaczmarek & Brainerd!
New findings reveal fascinating insights into air-breathing behaviors of royal knifefish, Chitala blanci. Like Amia calva, they use inspiration-first breaths to regulate buoyancy alongside four-stroke breaths for oxygen intake. Could this signal a broader trend in fish behavior? https://doi.org/10.1002/ar.25460

🌊🦆 Aquatic birds show diverse ecologies & movement styles, some excelling in water, on land, & in air. Using 3D geometric morphometrics, researchers analyzed their limb bone morphology. Results reveal size & locomotion influence shape, aiding understanding of adaptations & extinct species' ecologies. 🦅🔬
