China News Service, Fangchenggang, June 17 (Zhai Liqiang, Wang Weichen, Liu Fang) A suspected dinosaur fossil was recently discovered at the construction site of the Dongxing High-speed Railway Station Jinzhan Avenue project in Fangchenggang, Guangxi. The expert team confirmed that the discovery was a late Jurassic dinosaur. fossil.
At present, dozens of dinosaur fossil fragments have been collected and stored in a centralized manner, pending further research and identification.

On the 17th, the reporter saw at the site of the Zhanqian Road project of the Dongxing High-speed Railway Station that the site has been closed for protection, construction has been suspended, and ocher-colored rock formations are everywhere.
The dinosaur fossils temporarily stored in the Dongxing Natural Resources Bureau can clearly see the shape of their bones. The largest piece is 50cm long and 30cm wide.
It is understood that on June 10, at the construction site of Zhanqian Road of Dongxing High-speed Railway Station, worker Li Dongsheng found an abnormality in the rock during construction. He thought of the fossils he had seen, and reported to the project owner.

On June 15th, experts from Guangxi Third Geological Team, Guangxi Paleontological Fossil Expert Committee, Guangxi Regional Geological Survey and Research Institute and other institutions confirmed that these "abnormal" rocks were fossils of dinosaur skeletons in the late Jurassic period.

Huang Shan, a geological expert from the Third Guangxi Geological Team, believes that based on on-site surveys and comparison of basic geological data, it is confirmed that the rock formations exposed at the Zhanqian Road construction site were formed in the Jurassic period about 100 million years ago, and that the geological age happened to be a large animal dinosaur. Heyday.
According to Huangshan, the new 1:500,000 geological map shows that the coastline from Dongxing City to Fangchenggang City is about 50 kilometers long and 3.5-15 kilometers wide with Jurassic strata, mainly Upper Jurassic. Dongxing Formation, the second is Middle Jurassic Shiti Formation.
He suggested that future engineering construction and mineral exploration and development in this Jurassic stratum distribution area should consciously collect information on the remains of dinosaur fossils.

According to Lu Gang, an expert from the Guangxi Regional Geological Survey, the fossils currently discovered are mainly scattered in the late Jurassic strata, including the limb bones and vertebrae of dinosaurs. The specific dinosaur species need to be confirmed by further research.
The expert team stated that the Jurassic dinosaur fossils newly discovered in Dongxing City this time are older than the Cretaceous dinosaur fossils discovered earlier in Fusui County, Chongzuo City, Guangxi Province, which broadens the distribution range of dinosaur fossils in Guangxi. The study of habitat and its palaeogeography and palaeoclimate has provided new location and new data.

The expert team suggested that the dinosaur fossil discovery sites should be protected immediately, the dinosaur fossils that have been discovered should be collected, stored in a centralized manner for protection, the construction site and surrounding land should be protected, and experts should be immediately organized to discuss the excavation, protection and protection of dinosaur fossil sites. The further work of scientific research shall be implemented as soon as possible.
It is understood that the Dongxing City Government is preparing to establish a leading group for the protection of dinosaur fossils to do a good job in the long-term protection of dinosaur fossils.
