This four-winged dinosaur may have terrorized Earth's earliest birds

Scientists have uncovered a four-winged dinosaur called Jian changmaensis, suggesting it could have been a formidable predator of early birds. This newly identified glider, a relative of Velociraptor, sheds light on the interactions between feathered dinosaurs and the ancestors of modern birds in prehistoric times. The discovery of crushed bird bones in China points to Jian changmaensis as a potential culprit, offering a glimpse into the complex dynamics of ancient ecosystems.
