I think many people know the summer resort very well. Although they may not have been there in person, they must have seen it in history books. This is a palace built during the reign of Kang Yong and san huang in the Qing Dynasty. It took decades, and it integrated the characteristics of various regions in China, so you can enjoy a lot of scenery here. Recently, however, it has been discovered that this summer resort is actually a Jurassic Park. What does this mean?
1. Introduction to the Summer Resort
Chengde mountain resort is a famous tourist attraction in China, a world cultural heritage, a national AAAAA-level tourist attraction, a national key cultural relic protection unit and one of the four famous gardens in China.
Chengde mountain resort, also known as "Chengde Palace" or "Rehe Palace", is located in a narrow valley along the west bank of Wulie River in the north of Chengde City, Hebei Province. It was the place where the emperors of the Qing Dynasty spent the summer and handled government affairs.
The summer resort was founded in 1703, and it took 89 years to complete after Kangxi, Yongzheng and Qianlong in Qing Dynasty. The summer resort takes the quaint and elegant mountain village as its style, takes the true colors of natural landscapes and absorbs the scenery in the north of the Yangtze River, making it the largest existing ancient palace in China.
The summer resort is divided into four parts: palace area, lake area, plain area and mountain area. The whole resort is watery in the southeast and mountainous in the northwest, which is the epitome of China's natural landforms, a brilliant milestone in the history of China gardens, a masterpiece of China's classical garden art and the highest model of China's classical gardens.
On March 4th 196 1, the summer resort was announced as the first batch of national key cultural relics protection units. The Summer Palace, Humble Administrator's Garden and Lingering Garden announced at the same time are called the four famous gardens in China. 1February, 1994, was included in the World Heritage List.
2. The summer resort was originally Jurassic Park? The study of dinosaur footprints in Chengde area has been completed.
On the morning of February 6th, 65438, scientists from China, the United States and Australia announced that their research team had completed the study of dinosaur footprints in Chengde, Hebei. Surprisingly, most footprints are distributed on the ground of chengde mountain resort, the world-famous royal garden in China, which is a rare case in the world to combine paleontological remains with human history. These dinosaur footprints are numerous and well preserved, which is of great value for studying the evolution of dinosaurs.
Chengde mountain resort's discovery of dinosaur footprints has always attracted attention from all walks of life. Since 2007, Xing Lida, an associate professor of China Geo University (Beijing), has made a detailed study on a large number of dinosaur footprint fossils in Madigou, Summer Resort, Xumi Fushou Temple and Putuo Zongcheng Temple (Little Potala Palace), which not only enriched the dinosaur footprint fossil records in China, but also provided further strong evidence for the last Jurassic dinosaur activity in Chengde area.
Why do dinosaur footprints appear in humanistic buildings? It turns out that the origin of these footprint fossils-Madigou, produces paving slabs. Team Xing Lida focused on the footprint of Madigou at an altitude of about 800 meters. There are residential buildings on both the west slope and the north slope, and many of these buildings are built with local stones. From 1979 to the early 1980s, stone slabs in these areas were used to build eight temples in and around chengde mountain resort. In the spring of 200 1 year, Chengde county announced that Madigou was designated as a county-level cultural relics protection unit. At present, there are not many footprints left by Madigou, and a large number of footprints have been transferred and preserved on the ground of the summer resort.
The research led by Xing Lida is the most powerful official response to the discovery of a large number of Jurassic dinosaur footprints in chengde mountain resort, Hebei Province. After a detailed investigation, scientists found that at least the footprints of Deinonychus, Lei Long and Ankylosaurus were preserved in this area.
The footprint of deinonychus originated from the footprint point of Madigou, with an average length of 8.7 cm. The footprint has two toe prints (the third toe and the fourth toe) and a round heel, which indicates that it is related to Deinonychus and is classified as a raptor footprint. The footprints of deinonychus are rarely found in the world. At present, there are only red dragon footprints in Shandong, raptors in Sichuan and Harman red dragon footprints in South Korea. Deinonychus includes raptors and odontosaurus. The common feature of these dinosaurs is that they all have a big second toe like a switchblade, which is their "killer" in hunting. Interestingly, dinosaurs usually walked without touching the ground with their second toes, so they left two-toed footprints, collectively called deinonychus footprints.
The real footprints of Lei Long and Jumping Dragon are distributed in each footprint point of Chengde. These three-toe footprints have at least 140 footprints, of which 130 are complete footprints.
Korean bird footprints are distributed in Madigou footprint point. Footprint points save at least four continuous three-toed footprints. Morphologically, these bird footprints are classified as Korean ones. Korean bird footprint was first discovered in Xian 'an County, South Korea, which is a very typical Mesozoic bird footprint.
This survey found a variety of Tuchengzi dinosaur fauna. The fauna is obviously composed of sauropods (including theropods and sauropods), of which theropods and birds account for the vast majority. These abundant footprint records in Chengde show that the dinosaur evolution records in North China are basically continuous, starting from Liao Yan biota, to Tuchengzi footprint fauna, and then to Jehol biota.
3. dinosaur footprints are surprised on the stone road
On the morning of February 6th, 65438, scientists from China, the United States and Australia announced that their research team had completed the study of dinosaur footprints in Chengde, Hebei. Surprisingly, most footprints are distributed on the ground of chengde mountain resort, the world-famous royal garden in China, which is a rare case in the world to combine paleontological remains with human history.
These dinosaur footprints are numerous and well-preserved, which is of great value for studying the evolution of dinosaurs, and is of great significance for further exploring the behavior habits and living environment of dinosaurs, so as to restore the ancient environment of this area and the climate change during its geological period.
Although chengde mountain resort's discovery of dinosaur footprints has attracted attention from all walks of life and has been reported by the media for many years, it has never been confirmed by the official authorities.
Since 2007, Xing Lida, an associate professor of China Geo University (Beijing), has made a detailed study on a large number of dinosaur footprint fossils in Madigou, Summer Resort, Xumi Fushou Temple and Putuo Zongcheng Temple (Little Potala Palace), which not only enriched the dinosaur footprint fossil records in China, but also provided further strong evidence for the last Jurassic dinosaur activity in Chengde area.
"Judging from the large number of invertebrate remains on the ground of the summer resort, the world/kloc-0.5 billion years ago should be a relatively calm shallow lake with flat sand. This is also a prerequisite for all kinds of bugs and dinosaurs to leave footprints. "
Why do dinosaur footprints appear in humanistic buildings? It turns out that the origin of these footprint fossils-Madigou, produces paving slabs. Team Xing Lida focused on the footprint of Madigou at an altitude of about 800 meters. There are residential buildings on both the west slope and the north slope, and many of these buildings are built with local stones.
From 1979 to the early 1980s, stone slabs in these areas were used to build eight temples in and around chengde mountain resort. In the spring of 200 1 year, Chengde county announced that Madigou was designated as a county-level cultural relics protection unit.

Interestingly, dinosaurs usually walked without touching the ground with their second toes, so they left two-toed footprints, collectively called deinonychus footprints.
The real footprints of Lei Long and Jumping Dragon are distributed in each footprint point of Chengde. These three-toe footprints have at least 140 footprints, of which 130 are complete footprints. Among all the footprints, the medium-sized footprints with the length of 10 cm to 20 cm are the main ones. These footprints are divided into two types, one is morphological, the middle toe is relatively short, belonging to the real Lei Long footprints of theropod dinosaurs; Another morphological type, with a long middle toe, belongs to the walking dragon footprint. These footprints belong to small and medium-sized carnivorous theropod dinosaurs that walked on two feet. Because the sediment is soft and wet, the foot pad is not very clear, and the claw marks at the end are obvious. Functional toes are the second, third and fourth toes, and only a few footprints will leave traces of big toes.
Korean bird footprints are distributed in Madigou footprint point. Footprint points save at least four continuous three-toed footprints. Morphologically, these bird footprints are classified as Korean ones. Korean bird footprint was first discovered in Xian 'an County, South Korea, which is a very typical Mesozoic bird footprint. The largest of these birds is only 70 cm long and weighs more than 400 grams, so it is also called a small wading bird. Their common feature is that they live in various wetlands most of the time, mainly feeding on mollusks and arthropods, and most species have migration habits.
Chengde mountain resort's footprint has also produced some oval marks, which are similar to the back footprints of sauropods in morphology, such as Lei Long's footprint, the most famous sauropods in Cretaceous. However, due to poor preservation, there is no trace, and it cannot be completely confirmed at present.
This survey found a variety of Tuchengzi dinosaur fauna. The fauna is obviously composed of sauropods (including theropods and sauropods), of which theropods and birds account for the vast majority. These abundant footprint records in Chengde show that the dinosaur evolution records in North China are basically continuous, starting from Liao Yan biota, to Tuchengzi footprint fauna, and then to Jehol biota.
It is reported that in the next step, Chengde Cultural Relics Bureau and Xing Lida team will discuss the protection and utilization of dinosaur footprints, so as to promote the development and landing of tourism and popular science in Chengde.
