"Chinese Dragon King" Dong Zhiming re -swims "Dragon Palace"

Organized the excavation and research of Dashanpu Dinosaur Fossil Group Site

Zigong City, Sichuan Province, is located in the south of Sichuan Basin. Its geological history is long, with complex structures, rich minerals, and sufficient energy.

The earliest discovery of Zigong dinosaur fossils traced back to 1915, but the most important discovery was 1972, that is, the discovery of Dashanpu dinosaur fossils, it opened the prelude to the excavation, research and protection of this world -class dinosaur cemetery.

Speaking of the excavation and research of Dashanpu's dinosaur fossil site, a person must be mentioned. He is a famous dinosaur expert, Dong Zhiming, a researcher at the Institute of Ancient Research of the Chinese Academy of Sciences and the Institute of Ancient Human Research.

In 1962, Dong Zhiming graduated from Fudan University and was mainly engaged in the field collection and research of dinosaur fossils. In 1972, Dashanpu's dinosaur fossil site was discovered. A few years later, Dong Zhiming organized the excavation and research of the site. His footprint has traveled throughout the land of the motherland. He has presided over a joint investigation of dinosaurs such as the China-British, China-the United States, and China-Japan. He is the first dinosaur expert in my country to participate in the survey of Arctic stone. He was also named after 36 dinosaurs, once known as the "Chinese Dragon King".

On the opening day of the seminar, Dong Zhiming visited the Zigong Dinosaur Museum collectively with other experts and scholars. He told the Red Star Journalist that at the time, it was still a desolate place, and the excavation conditions and research technology were relatively poor. With the continuous development of socioeconomic and economy and the increasing progress of science and technology, the Zigong Dinosaur Museum has "getting better and more and more perfect" in terms of construction, scientific research, and science popularization.

"For so many years, I will come to Zigong in Sichuan for so many years. My life and professional hobbies have been integrated with Zigong." Dong Zhiming couldn't help feeling in the interview of experts. He recalled that on December 17, 1979, the Sichuan Southwest Mining Area Complex of the Sichuan Provincial Petroleum Administration of Sichuan Province built a parking lot on the requisitioned land. Accompanied by the breakout of "Boom", the dinosaur fossil buried in the small hills mountain bag was thrown on the ground ...

After rescue excavation, experts collected a large number of precious fossils. Experts such as Dong Zhiming have reported important dinosaur species such as Bashan Emirates, Building Qi Long, Tai Baihua Yanglong, etc., revealing the significance of the Dashan shop dinosaur animal groups in evolution, making Dashanpu the most important mid -middle Jurassic in the world. The world dinosaur fossil site, therefore won the National Natural Science Science Award in 1993.

In 1983, the Zigong Dinosaur Museum began to build, and Dong Zhiming also made suggestions for the construction of the museum. "More than 40 years have passed. Watching Zigong has become the famous' Hometown of Dinosaur", and I am deeply relieved. "Dong Zhiming said, hoping that Zigong would continue to polish the golden signboard of the" Hometown of Dinosaurs ", which is getting better and better.

Today's Dashan Panel dinosaur fossil site is not only an important dinosaur fossil site in my country, but also one of the most important paleomantic fossil sites in the world. Its discovery was once known as "a new milestone in the history of Chinese dinosaur research" and "the biggest gain in the history of world dinosaur excavation research in the history of nearly two decades."

my country has not found a clear three -stack dinosaur fossil so far

But early dinosaurs' footprints showed that during this period, dinosaurs were already in the Sichuan basin

It is reported that the theme of the seminar was "discovery and breakthrough" for four days. During the meeting, experts will share new discoveries, new achievements and applications in the global dinosaur research field.

On the afternoon of the 26th, Peng Guang, a researcher at the Zigong Dinosaur Museum, made a theme report called "Sichuan Basin Dinosaur Discovery and Research New Progress".

According to Peng Guangzhao, the Sichuan Basin is one of the four major red basches in China, with an area of ​​about 200,000 square kilometers, including the vast areas, Chongqing and parts of the northern part of Guizhou, except the Sichuan Plateau. The control of the two structural lines in the southeast constituge the irregular diamond shape that extends from northeast to southwest. In the basin, the middle -student land -phase and ground -stratum systems are fully developed, sedimentary continuous, clear sequences, and wide distribution, which contains a large number of dinosaurs and other vertebrate fossils.

Peng Guangzhen pointed out that according to the current discovery, research and distribution of dinosaur fossils in the Sichuan Basin, the focus of future work will be "finding dinosaur fossils in the late Triple Cracity", "Exploring the combination and evolution of early dinosaurs of Jurassic", "Discussion The four aspects of the Times of the Menxi Dragon Animal Group of Shangshaxi Temple and the Magenxi Dragon Animal Group "and" Study the Sichuan Basin's Period of the Period of the Basin ".

Regarding "Finding Dinosaur Fossils in the Late Triple Period", Peng Guangzhuang said that so far, there has been no clear tri -stacker (Note: a geological age from 250 million BC to 200 million BC, it is located in the two -stack of two stacks. Dinosaur fossils between Ji and Jurassic). The three -stacked Tongxu River group on the Sichuan Basin was revealed at the edge of the basin and some of the back inclined nuclear in the basin, and the early dinosaur footprints were discovered in the Pengzhou magnetic peaks, Ya'an Tianquan and Zigong Fushun The basin activity found that their bones were very likely. Recently, some skeletal materials in the horseshoe town of Gulong, Sichuan, released a strong discovery signal to the experts. During the seminar, the Zigong Dinosaur Museum will also hold the "Dragon" Tengda Mountain Shop -commemorate the 50th anniversary exhibition of the Tonggong Daishan Panel Dinosaur Fossil Group. The chapter shows the difficult journey of discovery, protection and utilization, innovation and development of Dashanpu fossil site.

It is reported that in the past 50 years, the protection and utilization of the dinosaur fossils of Zigong Dashanpu has always been at the forefront of the province and even the country. In 1987, the Zigong Dinosaur Museum, which was built by the site, was the first professional museum of dinosaur themes in my country. In 2001, it became the first national geological park and 2008 to the world geological park.

It is particularly worth mentioning that in recent years, the Zigong Dinosaur Museum has actively integrated into the construction of the Shuangcheng Economic Circle of Chengdu and Chongqing. The Luoji Stylus and Potena Research Center ", the" Dinosaur Discovery Museum "at the Zigong Dinosaur Museum No. 2 is stepping up its exhibition, which is about to build the opening of the museum, laying a solid foundation for creating a research museum.
