Uncovering the Secrets of Dinosaur Wrists
Recent findings reveal that the wrist structure of dinosaurs may reshape our understanding of flight evolution. Researchers analyzed two theropod dinosaur fossils and identified a pisiform bone in their wrists. This carpal bone, previously overlooked, plays a crucial role in the mechanics of flight. By studying this bone, paleontologists can gain insights into how dinosaurs transitioned to flying creatures.
This discovery challenges long-held beliefs about how dinosaur anatomy contributed to flight. The presence of the pisiform bone suggests that these creatures had more complex wrist structures, allowing for greater flexibility and movement. Such adaptations might have paved the way for the evolution of avian flight.
