Dinosaurs are prehistoric Mesozoic terrestrial paleogene reptile mammals. From the Triassic period 230 million years ago to the late Cretaceous period 65 million years ago, they dominated the earth for more than 160 million years. In particular, the plant-eating dinosaurs have the largest reminder, with a length of up to 58 meters and a weight of 150 to 180 tons, making them a "big Mac".
On the south mountain of the newly established group of Yangshan Village, Tianquanhu Town, Xuyi County, there is a huge rock with a sudden hillside, covered with moss. Strangely, there are several huge "footprints" on the stone, one of the largest footprints: the three toes are spread out in a fan-shaped shape, each toe is about 60 cm long, 15 cm deep, and about 80 cm wide. The stone has not cracked intact, and the marks on it are by no means "false marks" formed by the cracks, but are truly "printed". What guy has such great power that he actually "stepped" such a big and deep "footprint" on the stone? From the shape of the mark, the three toes are spread out in the shape of "公", which is very similar to the dinosaur footprint. Is it really a dinosaur footprint?

According to relevant information, there have been many reports of dinosaur footprints found around the world over the years. For example, in 1982, the largest of the dinosaur footprint fossils was discovered on the coast of Gyeongsang South Doi, South Korea. The largest one is 120 cm long and 64 cm wide. It is believed to be left behind by Brachiosaurus. It is inferred that this Brachiosaurus is 30-35 meters long and weighs 70-100 tons. In 1998, the dinosaur footprint fossils discovered in Wyoming, USA were about 1 meter wide and were left by gilled dinosaurs. It is estimated that the dinosaurs are about 30 meters long.
has also found a lot in my country. In 2001, the fossil dinosaur footprints unearthed in Yongjing County, Gansu Province were 1.5 meters long and 1.2 meters wide. They were left behind by sauropod dinosaur from the late Jurassic to the early Cretaceous period. Experts estimate that the dinosaur's body length should be more than 30 meters. In recent years, many discoveries have been made in various parts of our country. For example: The footprints of sauropod dinosaurs found in Gulin, Sichuan are 60 cm long and 54 cm wide. Dinosaur footprints were found in Shenmu, Shaanxi Province, 41 cm long and 24 cm wide. The footprints of sauropod dinosaurs in the Chabu area of Ikezhaomeng, Inner Mongolia are round, with a diameter of 90 cm and a small one; one of them is 30 cm long and a step length of 2.8 meters. After calculation, the running speed can reach 41 kilometers per hour.

Whether there have been dinosaurs in the southwest mountainous areas of Xuyi have lived? Previous information has not recorded. However, in the territory of Laian County, near Yangshan Village, Tianquanhu Town, there are many places with the word "long" name, such as Longshan, Longtougang, Dunlongshan, Chelonggang (west of Dayuying), and Longwo (west of Banta Tea Farm). According to the "Laian County Chronicle" of Daoguang of the Qing Dynasty, the "Matou Mountain" adjacent to the south mountain of Yangshan Village records that "it is said to be a dragon through this". It is also circulated among the local people, "In ancient times, there was a story about "When I visited my mother's experience, I knew that my mother had died, and I was so sad and angry that I left traces of the stone."
According to the records in the "Xuyi County Chronicles", "When Huanong Reservoir and Guiwu Reservoir were built in 1958, a large number of ancient trees dug out from the deep soil of the ravine. The studs were thick and neither of them could hold them." According to information such as the ancient Jianghuai 's climate was warm and humid, and the forests were lush, which was suitable for the survival of dinosaurs. To this day, "two-colored scaly fern" grows in the valley of Tieshan Temple , also known as " Phoenix Tail fern ", which is a plant of the same age as dinosaurs and is known as "living plant fossils". This proves that dinosaurs survived in the Tieshan Temple mountain area in ancient times, and it is not impossible.

If the "rock footprints" found in Yangshan are really dinosaur footprints, referring to the research results of the footprint data of other dinosaurs, the "Yangshan Dinosaur" should also live in the Jurassic to Cretaceous period 150 million to 70 million years ago. It belongs to a large "plant-eating sauropod dinosaurs". It is about 30 meters long and weighs more than 50 tons. It is an amazing behemoth.

When talking about the formation of "Yangshan dinosaur footprints", a "scene reappearance" can be made based on scientific data:
In the late Cretaceous period about 65 million years ago, a volcano erupted, and magma overflowed. The originally tall and lush trees were burned, the leaves were roasted, and the plants were burned. The magma on the ground was solidified, and the hot high temperature was still emitting. The entire Tieshan Temple mountain area was full of strong burnt smell.
A huge sauropod dinosaur has long lost its majesty. It has not eaten for many days and is shaking and running on the hot earth. It wants to find a watery and green tree! However, everything in front of him made it feel desperate.
When it ran to the south of Yangshan and saw a red grassland, it seemed to see hope and ran over quickly.
When it stepped on a huge rock that was about to solidify, it felt why the stone was so soft. One foot fell down. The hot rock suddenly hurt the dinosaur's feet, making it unstable, and it fell heavily to the ground. It wanted to struggle to get up, but it could never get up again.
It could only wail, letting the rolling volcanic stone hit the body and the erupting volcanic magma poured on it. It looked at the sky helplessly, and looked at the beautiful home where it once lived in despair, slowly closing its eyes with endless regrets. ...
The dinosaur left, but the footprint it left on the boulder told later generations: "I have been here once."
