Jurassic fossil fills gap in evolution of bird tails
A 150-million-year-old fossil discovered in China has provided new insights into the evolutionary transition from long-tailed dinosaurs to short-tailed modern birds. The discovery of the species Zhengheornis buyu helps bridge a significant gap in paleontological understanding regarding tail anatomy.
Why it matters
This discovery resolves a long-standing debate in evolutionary biology, providing concrete evidence for how specific skeletal structures evolved in avian ancestors.
A 150-million-year-old fossil unearthed in Fujian province has revealed what researchers say is the smallest known long-tailed bird from the Late Jurassic period, filling a critical gap in scientists' understanding of how dinosaurs' long tails evolved into the short, compact tails of modern birds.
