One hundred and fifty million years ago, a creature no heavier than a small handful of coins lived and died in what is now Fujian province, China — and in dying, preserved an answer that science had long assumed was lost forever. The fossil of Zhengheornis buyu, unearthed in 2024 after more than 400 days of excavation, offers the missing chapter in one of evolution's most debated transitions: the gradual shortening of the dinosaur tail into the compact, fused structure that allows modern birds to fly. Its fifteen unfused vertebrae place it precisely between the long-tailed world it came from a

Tourism (paleontology sites)
No direct impact on consumer goods, services, or household finances. Potential long-term indirect benefits through enhanced science education and increased tourism to fossil sites in China.
May influence science education curriculum development and funding allocation for paleontological research in China. Could support arguments for environmental protection of fossil-rich geological sites. Strengthens China's position in international scientific research and academic prestige.
