Sichuan dinosaur footprint map exposure: The ancient Shu land of hundreds of millions of years ago was a "dinosaur kingdom"

Cover reporter Liu Jian Wang Yuexin

Not long ago, the dinosaur footprints were found in the Sichuan Ledshan Horticultural Forest Restaurant, which made the "Dinosaur Hunter" -Datalole Tutor and Associate Professor of China University of Geosciences excited: "Find dinosaur footprints when eating a meal. Science popularization. success."

At the same time, researchers Peng Guangzhao and Ye Yong were at the Zigong Dinosaur Museum at 120 kilometers away. This map is called "Sichuan Dinosaur Footprint Map". The map shows that there are at least 42 dinosaur footprints in Sichuan Province so far, exceeding 1/4 of the total number of dinosaur footprint fossils that have been found in China, ranking first in the country.

Xing Lida said that Sichuan is the area with the most dinosaurs and the most diversity. This means that the ancient Shu land was a "dinosaur kingdom" hundreds of millions of years ago.

42 places have been found

Sichuan Dinosaur Footprints ranked first in the country

For almost 40 years of dealing with dinosaurs, Peng Guangzhong, a research librarian of the Zigong Dinosaur Museum, will retire next year. Before retiring, Peng Guang was busy with a "big event": he and Ye Yong and his colleagues compiled the publishing work of the "Sichuan Basin Dinosaur Football". "In 2018, we organized the research results of dinosaur footprints. After more than 4 years of enrichment and improvement, this book will be published in two or three months."

In this book, a map has attracted much attention. Peng Guangzhao said that this map is a Sichuan dinosaur footprint map, a drawing from the perspective of geographical distribution points.

In the masterpiece of Peng Guangzhao, Ye Yong and others to publish soon, the Sichuan Basin Dinosaur Map.

According to the data and maps provided by Peng Guangpiao and Ye Yong, the Sichuan dinosaur footprints are mainly distributed in 11 cities and states in the province, namely Chengdu, Ya'an, Dazhou, Guang'an, Bazhong, Leshan, Zigong, Yibin, Luzhou, and and. Liangshan Prefecture. According to statistics, Sichuan Province has found at least 42 dinosaur footprints so far, including 29 in the basin and 13 Liangshan Prefecture.

"It can be seen that there have been dinosaurs from north to south, from north to south, from north to south, from west to east." Peng Guangzhao said that 6 cities and states are the most abundant dinosaur footprint fossils, namely Leshan, Zigong, Neijiang, Yibin, Luzhou, Luzhou, Luzhou, and Luzhou. There are 36 places with Liangshan Prefecture, accounting for 85.7%of Sichuan dinosaur footprint fossils.

Not only did Sichuan have many fossils of dinosaur footprints, but large -scale dinosaur footprint fossils were also found in Sichuan. "At present, we have discovered three large -scale dinosaur footprint fossils in Sichuan, such as the fossil point of the main footsteps of Emeikawa, the Hanxi footprint fossil point of the ancient osmanthus flowers in Luzhou, and the three than the three than the fossils of the San than the San than Ye Yong said.

The wolverine foot dinosaur footprint discovered by Luzhou Gulin Beili Garden was named Shunan Liu Jian's footprint.

"The dinosaur fossils in Sichuan are rich. Just pay attention to the section of the courtyard, highway slope, construction site, quarry, and other sections." According to the relevant information, as of now, Sichuan dinosaur footprints The number of points exceeded China, which has discovered 1/4 of the total number of dinosaur footprint fossils, ranking first in the country.

This assertion was affirmed by Associate Professor Xing Lida, a doctorate instructor of China University of Geosciences (Beijing). For more than 20 years, Xing Lida pursued dinosaur footprints at home and abroad for a long time, and Sichuan dinosaur footprint discovery, he almost all participated. "As far as I know, there are more than 42 dinosaur footprints in Sichuan, and this number should be the largest in the country."

Experts inspect dinosaurs in Gulin County.

Sichuan dinosaurs are the most abundant

What dinosaurs are left? Through the research and judgment of the characteristics and shapes of footprints and shapes, experts made the dinosaurs living in Sichuan a one -year -old dinosaurs "appear" one by one.

"In the dinosaur footprints of Baihua Town, Yibin in 2019, 5 large beast foot traces are judged as solid thunder dragon footprints. Small three -toed footprints are two dragons, and the other one is a bird. The strange dragon footprints of the hip group. "Peng Guangzhen said that the footprint of the footprint found in the Qianfuyan Scenic Area of ​​Jiajiang is a small and medium -sized meat dinosaur, and the footprint discovered in Leshan Restaurant this time is left by the food and planting dinosaurs. of.

"Sichuan dinosaur footprint types are diverse, there are both a single type of footprint fossil point, and there are many kinds of footprint fossils that coexist in footprints; both rich concave footprints and a large number of three -dimensional convex footprints. China ’s smallest length of only 2cm dinosaur footprints and so on." Ye Yong said that at present, Sichuan Province has found 15 footprints with a total of 16 footprints in Sichuan Province, and more than 20 footprints have not been set. In terms of type, it exceeds the current 1/5 of the dinosaurs.

Xing Lida made a judgment based on this: From this data, Sichuan dinosaurs are also the areas with the most rich dinosaur footprints in the country.

In this regard, Peng Guangzhao agreed. He said that these dinosaur footprint fossils proved that the dinosaurs who lived in Sichuan hundreds of millions of years ago were not only four major categories such as ham canal, beasts, bird feet and armored dragons, but also pterosaurs flying in the sky, and as well as the sky flying in the sky, as well as the sky flying in the sky, and the pterosaurs flying in the sky, as well as Water birds living by the water.

Experts collect dinosaur footprint data on the cliffs of Gulin County.

Some are running and some are swimming

What can I read from these "foot board prints"? Peng Guangzhen said that these footprint of fossil information can not only identify the types of creators, but also "reproduce" the living conditions of dinosaurs at the time.

Peng Guangzhen said that, such as the fossils of the Fushun Flow of Fun Shun Fun Fun Tinylona, ​​which is very likely to be left by the little dinosaurs who were born shortly; the dinosaur footprints found by the Pakistani River were clear and the stride was large Fast; the carnivorous dinosaur footprint found by Baihua Town, Yibin is "running", suspected to be hunting, which is very rare; the footprint of Zhaojue County, Liangshan, not only the shock and spectacular area of ​​9,000 square meters, but also found some dinosaurs. Qunju evidence has even found evidence of the world's first conclusive dinosaur swimming. In 2018, experts conducted investigations and data collection on the site of Zhaojue Sanbela.

Foot board printing status

One of the earliest origin of Sichuan or Chinese dinosaurs

As a "dinosaur hunter", many people will ask Xing Lida after finding dinosaur footprints. "Leshan Restaurant is found to find me on Weibo." Xing Lida said that the fate with Sichuan dinosaur footprints also has nearly 20 years. The process of pursuing dinosaur footprints is like a colorful puzzle. Every time he discovered, he would excite him and harvest.

"The discovery of the Sichuan dinosaur footprint fossils has a pivotal position in the country." In Xing Lida, in addition to the types and quantities, the Sichuan dinosaur footprint fossils from the evening of the world The Jurassic World -Late Juraki -Early Whitening World -The strata of various eras of the late white world found that the geological age of dinosaur footprint fossils is continuous and complete, which is very rare in my country.

In addition, the three places (Pengzhou, Tianquan, and Fushun) discovered in Sichuan in the evening of the three -stack of dinosaur footprint fossils have become the earliest records of dinosaur fossils in China. This discovery has filled a period of gap in the discovery and study of Chinese dinosaur fossils, indicating that Sichuan may be one of the earliest origin of Chinese dinosaurs and has very important scientific value. "There are also great possibilities to find more dinosaurs in Sichuan, because the strata that belong to the dinosaur period have appeared elsewhere."

While the restaurant found the hot search on the footprint of dinosaur footprints, it also caused the public to worry about the protection of dinosaur footprint fossils. So, what are the suggestions for the protection of dinosaur footprint fossils?

“四川已经有些地方对恐龙足迹采取了保护措施，如搭上保护棚。”彭光照说，但目前，对于恐龙足迹化石的保护，暂没有一套科学方案和行之有效的措施，再加上Pay attention to not enough, fossils in many places have shown signs of reduction. "The most important thing is natural weathering factors, which is difficult to avoid."

"The protection of dinosaur footprint fossils is a worldwide problem." Xing Lida said that dinosaur footprint fossils are mostly on the remote countryside and steep walls. Long -term exposure is exposed, and weatization and human factors will increase the reduction of footprint fossils.

Xing Lida suggested that Sichuan can refer to the protection experience of cliff statues such as Leshan Great Buddha and Anyue Stone Carvings, and find effective protection measures for dinosaur footprints, so that this trace from hundreds of millions of years ago stayed in the world longer, stay for longer, stay for a longer time, stay for a longer time, stay for a longer time, and stay in the world. After the future.
