Dragon Travels the Gobi: Cretaceous Dinosaurs from Inner Mongolia
The Mongolian Plateau is one of the hot spots in the study of paleo-vertebrate zoology and biostratigraphy in the Cretaceous period. Since the 1980s, many valuable reptile fossils, including dinosaur bones, eggs and embryos, skin marks and footprints, have been discovered in the Gobi Basin and Erlian Basin of Inner Mongolia, which are of great significance to the study of the global classification of dinosaurs, the mystery of dinosaur extinction, and the exploration of the geographical and climatic changes of the ancient Mongolian Plateau.

Among the exhibits of interest is the fossil of Gigantoraptor Erlian. Gigantoraptor Erlian is the largest known oviraptorid dinosaur, with a body length of about 8 meters and a standing height of more than 5 meters. Its fossils were first discovered in Erlian Basin, Inner Mongolia in 2005. Gigantoraptor Erlian is a special case in the evolution of dinosaurs into birds. Despite its large size, it has more bird-like characteristics than the small oviraptorosaurs, which greatly enriches human understanding of the evolution of dinosaurs into birds.
Other important exhibits include the perfect Bayannur fossil, which is important for understanding the early evolution of iguanodon, the Dong’s Chinese ornithlike fossil, which is preserved in situ and more than 90% complete, and the Gobi Psittacosaurus fossil, which contains several gastroliths.

Alsophila spinulosa tree, which was once eaten by dinosaurs. In Rongxian County, Zigong, there are not only the Qinglongshan site of Mid- Jurassic dinosaurs and other vertebrate fossils dating back 160 million to 170 million years, but also a “national treasure” Alsophila spinulosa tree growing naturally in Sifang Jinggou, Jinhua Township, Rongxian. In addition to nature conservation, Lee Yue-fu has successfully propagated Alsophila spinulosa tree with seeds (spores) since 2012. Nearly 30,000 Alsophila spinulosa trees were artificially bred. This tree was recently seen at the artificial breeding park near Alsophila spinulosa Lake in Dapyeong Village, Dongga-jin, Yeonggun.
“The Alsophila spinulosa tree is more than three metres tall and nearly 10 years old, and as you can see it is healthy and robust, it is a good seedling that can grow into a big tree.” Li Yuefu, the owner of the breeding park, stroked a tree trunk and said that the garden, which stretches for more than two kilometers in a mountain gully, has more than 30,000 artificially bred Alsophila spinulosa trees ranging in age from one to 10 years, among which some are potted, some can be used for landscaping and some are suitable for popular science tourism.
The Alsophila spinulosa Nature Reserve, a nature reserve of Sichuan Province, is one of the eight national key protected plants, with a living fossil of Alsophila spinulosa that appeared in the Carboniferous period and is 300 million years old, 100 million years before the emergence of dinosaurs, Li said. The local villagers take special care of the “national treasures” in the reserve. In order to allow these “national treasures” to be “reborn” in a different place, they use the seeds of “national treasures” for artificial reproduction and achieve success.
Lee is known to have established the Alsophila spinulosa Bay Ecological Agriculture Development Co., Ltd. in Zigong City to make the artificially bred tree more productive. In addition to artificially breeding Alsophila spinulosa trees to be sold in and out of the province for landscaping and popular science tourism, the company is developing a series of Alsophila spinulosa tea and Alsophila spinulosa wine.

It is a common question on the Internet: Why did dinosaurs fail to produce intelligence after hundreds of millions of years of evolution? Human beings, on the other hand, only took millions of years to develop an advanced intelligent civilization. Why is that?
To put it simply, dinosaurs did not need to evolve intelligence, nor did they have the ability and conditions to evolve intelligence, while human beings evolved intelligence can be said to be forced to.
Let’s start with why we evolved intelligence.
An important prerequisite for the evolution of human intelligence is the brain, and the evolution of the brain is fundamental. According to the current mainstream theory, the ancestors of modern humans came from East Africa, where Homo sapiens evolved and then spread around the world.
The nature of species evolution is actually genetic variation, but in the process of inheritance, variation is completely random behavior, we cannot predict the direction of variation.
Since evolution is variation, and variation is random, evolution is also random and directionless. In the course of evolution, nature makes choices all the time, and the ones that don’t fit will eventually be weeded out, and the ones that do will stay.
According to the mainstream theory of human origin, the ancestors of human beings are the apes living in East Africa. Due to environmental changes, such as the emergence of the Rift Valley in East Africa, the climate of East Africa went through great turbulence, and the dense forest eventually became grassland, and the apes living in the forest had to move from the forest to the grassland.
When they first came to the grassland, the apes were certainly not adapted to it, and it took millions of years of trial and error. Originally in the forest, with flexible skills, the ancient ape can be called the king of the forest, life is very comfortable. But when they came to the prairie, they fell from heaven to hell. Without the ability to run fast, it is difficult for an ancient ape to take advantage of a wild animal.
Over a long period of time, the apes have been severely tested. But one group of ancient apes stood out, starting by walking upright. The variation of upright walking is not achieved overnight, nor can it be changed at the will of the apes. Instead, it has been trial and error in the process of continuous variation, undergoing survival of the fittest, and finally the upright walking variant gene has the last laugh, which has been screened by nature.
Walking upright has huge advantages over crawling on all fours. Walking upright, for example, saves energy, frees up hands and allows the apes to move quickly when attacked by an animal. At the same time can also make use of attacks, greatly improve the efficiency of obtaining food. By walking upright, the apes also had a higher view of the beasts and were prepared in advance.
Survival is a basic skill that any species must possess, and walking upright would have made it much easier for an ancient ape to survive.
Now, walking upright also laid the foundation for later human civilization. Without upright walking, the large brains of the ancient apes would have had no support at all. Even with the relevant genetic mutations, intelligent civilization would not have evolved in the end, but only a flash in the pan.
However, the expansion of brain capacity is not all good, because the brain’s neural network is too complex, to maintain the brain needs a lot of energy consumption, scientists analyzed that human brain energy consumption accounts for more than 20% of the total energy needed by the human body, which was not friendly to primitive humans, because primitive humans have very limited means to obtain energy, energy is quite scarce. But in order to maintain the brain’s energy expenditure, they had to reduce the body’s other energy expenditure to keep the brain’s energy needs as high as possible.
The benefits of having a larger brain are numerous. That means stronger and more efficient abstract thinking skills, organizational communication skills, hands-on skills, etc. These increased abilities greatly enhanced the quality of life of both the hominids and the hominids, who soon rose to the top of the food chain.
When human beings were no longer tired for food, the society began to evolve a lot of different division of labor, and human beings also had enough time and energy to study science, art and other fields, which led to our modern civilization.
So why didn’t dinosaurs evolve an intelligent civilization?
To put it in plain English, because dinosaurs were completely the “rich second generation”, they lived in an evolutionarily perfect age, there was no conditions and motivation for the evolution of wisdom.
Dinosaurs lived at a time when plants and animals were everywhere, which was heaven for herbivores and meat-eating dinosaurs. The so-called born in distress and die in happiness, in such a beautiful living environment, they have no evolutionary wisdom power.
One more point, mentioned at the beginning of the article, is that evolution is a very random behavior, and even dinosaurs would have needed genetic variation in this aspect to develop intelligent brains. At the very least, even if a particular group of dinosaurs were genetically modified to be more intelligent, that wouldn’t give them an advantage, it would be a disadvantage, because intelligence means greater energy expenditure. Right
If there were no advantages, nature would not have evolved in this direction! For dinosaurs, their big mouth and big body is “ wisdom”, at the time, there is no better use of such wisdom!
Finally, there is no high or low level of evolution. Evolution does not necessarily evolve in the direction of intelligence. The only purpose of evolution is to adapt to the environment, and there are many ways to adapt to the environment, intelligence is just one of them.

A dinosaur fossil unearthed in 2021 at the construction site of the front road of a high-speed railway construction project in Dongxing City has completed the first stage of restoration after a one-month restoration by technicians from the museum of Hebei University of Geosciences.
On February 3rd, the reporter came to the Dongxing Dinosaur Fossil Herbarium and saw that the dinosaur fossils collected in the room were arranged neatly, each fossil was numbered in detail, and the restored dinosaur fossils showed clear skeletal Outlines. It is known that in 2021, 363 dinosaur fossils have been excavated during the construction of the front road of Dongxing high-speed railway construction Project. At present, experts have repaired the cervical vertebra, dorsal vertebra, tail vertebra, neck rib, femur and other skeletal fossils, which are preliminatively determined to be sauropod dinosaur fossils.
Zeng Chunjun, director of the technology department of the Museum of Hebei University of Geosciences, who participated in the restoration work, said that before the Spring Festival, they carried out restoration work on the missing dinosaur fossils, mold making, mold turning, and scaffolding, and the progress was relatively smooth. For now, the restoration work has been suspended, pending the next discovery of new dinosaur fossils.
The reporter saw in the dinosaur fossil excavation site, the site set up a enclosure protective awning, to protect the exposed dinosaur footprints fossil specimens. Remarkably, five dinosaur footprints, about the size of a human hand, are spaced out on a boulder. According to the staff, the footprint fossils and bones they found are different kinds of dinosaur fossils, and the expert study determined that they were theropod dinosaur footprint fossils. It is understood that the footprint remains fossil and bone solid fossil are formed by dinosaurs in different nature and buried environment. It is often difficult to have two fossils in the same formation on a smaller scale. The simultaneous discovery of two fossils at the same site in Dongxing is rare among dinosaur fossil excavations in China and has important research value.
