Core Viewpoint - The discovery of the Cretaceous dinosaur fossil group in Qianjiang, Chongqing, positions it as the only site of its kind in Southwest China, enhancing the region's paleontological significance and potential for cultural tourism [1][2]. Group 1: Fossil Discovery and Significance - Qianjiang is now recognized as the only Cretaceous dinosaur fossil cluster site in Southwest China, filling a gap in the region's paleontological research [2]. - The Cretaceous dinosaur fossils discovered are approximately 80 million years old, with over 400 fossil discovery points identified across a 5.7 square kilometer area [1]. - The fossils include sauropod, ornithopod, and theropod species, noted for their good preservation and high research value [1]. Group 2: Research and Academic Contributions - The newly identified dinosaur species "Changsheng Qianjianglong" represents the first hadrosaurid genus discovered in Southwest China, contributing to the understanding of Late Cretaceous dinosaur fauna in East Asia [2]. - Experts have recognized the Qianjiang fossil site as highly representative, with rich fossil resources and significant research value [2]. Group 3: Cultural and Economic Development - Qianjiang is actively promoting the integration of dinosaur fossil resources with cultural tourism, aiming to develop a "Dinosaur City" [2]. - A core protection area of 1,200 acres has been designated for urban development, alongside the establishment of the Chongqing Cretaceous Dinosaur Research Center [2]. - Plans are underway to create a dinosaur heritage park, cultural industry park, museum, and digital experience center to enhance public engagement and education [2].
