Descubierta en el yacimiento conquense de Las Hoyas una nueva especie de ave del Cretácico con pico dentado. Se asemeja a un martín pescador y entronca con el grupo biológico de los 'Longipterygidae', que hasta ahora solo se habían documentado en China

Say👋 to *Gorgonavis alcyone*, the newest enantiornithine bird from the Early Cretaceous of Spain✨🐦 We welcome here the 1st adult cranial remains of a bird from the fossil site of Las Hoyas, and the 1st longipterygid out of China... Thread!!🧵👇 Paleart by Roc Olivé

🌳🔨🐦 How do woodpeckers withstand the impact of pecking? Their most iconic behavior is possible thanks to (1) unique cranial joints and (2) bypassing a general rule of skull transformation in other birds in favor of the influence of a larger brain👇 doi.org/10.1111/joa....

Skull evolution in woodpeckers via articular innovation and allometric decoupling facilitates pecking performance
Woodpeckers evolved reinforced cranioquadrate–mandibular articulations and distinctive cranial shapes that stabilize the skull under extreme pecking loads. These osteological innovations, together wi...

🌳🔨🐦¿Cómo aguantan los pájaros carpinteros el impacto al picotear? El comportamiento más característico de este grupo es gracias a (1) articulaciones craneales únicas y (2) a que se saltan una regla general de transformación del cráneo por incrementar el tamaño del cerebro. 👇 doi.org/10.1111/joa....

Great new paper on the evolution of birds - showing how changes in forelimbs (becoming wings) and legs were linked together. I LOVE research like this which reveals the secrets of how evolution works - how development, genetics, form are all joined up: royalsocietypublishing.org/doi/10.1098/...

🎉After many years since its gestation, our work is finally out in @royalsocietypublishing.org !!🦖🤝🐦 Morphological integration constrained large-scale evolution of the limbs in non-avian dinos and birds, is evo-devo behind this common pattern? Check it out here!👇 And my first post in @bsky.app !!
