远古发现|百万年前，古汉江或见证古人类与恐龙蛋化石“邂逅”

Core Viewpoint - The Qinglongshan dinosaur egg fossil site in Hubei Province is one of the most concentrated and complete areas of dinosaur egg fossils in the world, revealing significant geological and historical connections between ancient rivers and human activities [1][6]. Group 1: Geological Findings - The Qinglongshan site has revealed large-scale ancient river terraces, indicating that the ancient Han River flowed through the area about one million years ago, transporting gravel to the vicinity of the dinosaur egg fossils [1][3]. - The gravel layers are primarily found at two elevation ranges: one at 325 to 340 meters covering approximately 15 hectares, and another at 240 to 260 meters covering about 40 hectares [3]. - The dinosaur egg fossils and gravel layers are found within 10 meters of each other, suggesting that the ancient river's strong flow contributed to the natural exposure of the dinosaur eggs [3][6]. Group 2: Archaeological Insights - The study of the Qinglongshan site has revealed that ancient humans living near the Han River may have encountered exposed dinosaur egg fossils and potentially used them for tool-making [5]. - The findings at the nearby Xue Tang Liangzi site, where ancient human skulls and stone tools were discovered, support the hypothesis of human interaction with the dinosaur egg fossils [5]. Group 3: Future Research Directions - The research team plans to further investigate the evolution of the ancient Han River and its relationship with human development, aiming to enhance understanding of the geological processes that led to the exposure of the dinosaur egg fossils [7]. - Future studies may support new educational programs that integrate the cultural significance of dinosaurs and the Han River, enriching the scientific and cultural narrative of the Qinglongshan area [7].
