Lin Xing'an said: "This was accidentally found in a cave when I went to Luoxing Valley to collect plant specimens a few days ago. ”

"Have you gone to the Falling Star Valley?" Ling Zikai was taken aback: "A shocking discovery." ”

As for what secrets were hidden in the Falling Star Valley, Ling Zikai was naturally much clearer than Lin Xing'an.

He pondered that Lin Xing'an should have entered the cave where the Gusi people lived.

The cave with the remains of mysterious animals was obscured by those terrifying man-eating vines, and the unsuspecting would not have noticed.

Even if Lin Xing'an entered the cave where the Nagusi people lived, he probably found some fossils on the ground in the cave, and he did not find those murals carved on the cave wall. In terms of the value of the finds, those murals are many times more precious than these fossils.

In Ling Zikai's heart, he didn't want the outside world to discover the secrets inside the cave, which were the relics left by the Gusi people, and he had the responsibility to protect them.

"Uncle Lin, isn't it just a few fossils, in the Xing'an Mountains, it is possible to dig up such fossils by pulling a few times on the mountain, there is nothing rare!"

In order to dispel Lin Xing's curiosity, Ling Zikai deliberately belittled the value of these fossils, revealing a disapproving look.

Qian Lao nodded and said, "That's right, these ancient fossils, in addition to their own scientific research value, are now being used as collectibles. Because of the profit drive, many people make a living by digging fossils, so that these fossils that have been silent for tens of millions of years are displayed in front of the world in large quantities, forming a flood, and their value is greatly discounted.

Take Lao Guan in the base as an example, he is an enthusiast of fossil collection, and when he has nothing to do, he takes a small iron pickaxe and tinkers in those small ravines near the base, and really let him find many fossils and put them in the base as decorations. I also spent a lot of time with him before I learned a little bit about fossils. Otherwise, I'm an energy worker, how can I recognize the origin of any fossils!"

Seeing that Ling Zikai and Qian Lao were not interested in these fossils that they had obtained as if they had obtained a treasure, Lin Xing'an seemed to be a little anxious and said, "You all misunderstood. I also know that these fossils in front of me are not of much value, the key is the fossils of these grains of rice!"

Lin Xing'an picked up the few rice fossils placed on the cardboard, and seeing that the two of them looked a little confused, he couldn't help but raise his voice a little, and said: "Although I haven't done a specific dating, it is certain that the age of these rice fossils should be at least more than 10,000 years. Have you ever wondered what it means for 10,000-year-old rice grains to appear in a cave?"

Lin Xing'an paused, accentuated his tone, and said: "That means that 10,000 years ago, there were already human beings living in that cave, and it is also possible that there was a primitive tribal civilization that already had slash-and-burn farming. If there are really relics of human civilization 10,000 years ago in that cave, it will inevitably cause a sensation in the archaeological community, and can even push the Chinese civilization directly to 10,000 years ago. Zikai, I think it is necessary for us to report to the higher authorities, and let the relevant departments send people to dig deep into the cave, and I believe that there will definitely be amazing discoveries. ”

Just when Lin Xing'an's face was full of excitement, he heard Ling Zikai say: "I don't agree!"

Lin Xing'an, who had just finished speaking, heard that his neck was choked, his mouth opened wide, and he couldn't close it half-loudly.

Qian Lao also looked at Ling Zikai with some puzzlement, and asked, "Discovering the relics of the ancient era, this is a very meaningful thing, why should you object?"

Ling Zikai was silent, his mind spinning rapidly, pondering what reason he wanted to use to refuse.

After a while, Ling Zikai said slowly:

"Uncle Lin, you also know that Falling Star Valley is the only primeval forest in the nearby mountain forests. If a large-scale archaeological excavation is carried out there, or if a site of ancient humans is indeed discovered, it will definitely attract more people to investigate and visit.

It may even be designated as a national cultural heritage protection or developed into a tourist destination. However, no matter what happens, it will cause damage to the surrounding natural environment, what will happen to my forest farm at that time? Uncle Lin, will your experimental base still be able to continue?

You may say that the discovery of the ruins is also a scientific project that is conducive to the study of the development process of human civilization, and even some sacrifices made by the forest farm will have more advantages than disadvantages. And the state will definitely give some financial compensation.

However, I wonder if you have considered another consequence, that is, whether the discovery of the site is a blessing or a curse for the site itself?

You must have seen some reports in the news in the past, that is, some ruins were found in such and such a place, but because some corresponding protection measures were not taken, the result was serious damage to the cultural relics.

Rather than such a situation, it would be better to let these ruins remain silent in the long river of time?"

Lin Xing'an and Qian Lao both fell into deep thought when they heard this.

"Another reason for opposition is that for thousands of years, there has been a legend in the place of Falling Star Valley.

It is said that there is a mysterious taboo in that canyon.

The large mouth basin is a tool of the "stone cooking method". After the stone is scalded with fire, it can be used to boil water or liquid food by putting it into a large basin where water or food is placed. If this conjecture is true, our ancestors would have ended the life of "drinking blood" as early as 10,000 years ago. Conjecture 2: The large mouth basin is a container for placing the grinding disc. The stone grinding disc unearthed from the mountain is put into a large mouth basin, and then the tuber plants (such as sweet potatoes, etc.) are ground on it, and the liquid starch is directly collected in the pot, avoiding waste. The ancestors of Shangshan had already had the idea of a "thrifty society"? Conjecture 3 The large basin is a "storage tank" without a lid. At that time, the earth's climate had just begun to change from dry and cold to warm and humid, and there was no concept of "moisture-proofing".

The archaeological team found that in the early strata of the Shangshan site, there was an area with moist soil, dark color and "fat". So, the team set up a "scout" in this area.

Surprises arose. During the screening, not only several milky white teeth of the "mountaineers" were obtained, but also pointed bone vertebrae 6 to 7 cm long were found.

Jiang Leping said that through the next step of laboratory analysis, we can determine the age and lifespan of the "mountain man", and even deduce what diseases he or she has had and what food he or she eats.

The discovery of bone tools is also useful for us to study what kind of production tools were used by the Shangshan people, and what animals accompanied the Shangshan people at that time.

In addition, Jiang Leping also revealed that there are some pelvic fragments that have not yet been formally identified. It seems that we are getting closer and closer to the real "mountain man".
