Because ancient people did not explore the natural world enough, they regarded some animal bones as dragon bones.
Modern vertebrate paleontologists point out that the Buddha bones that Han Yu blocked are also elephant-like fossils. Modern research results show that these fossils have no medical effect. It is just that the ancients did not understand the real situation and mistakenly thought they were those of mythical dragons.
That’s why the remains are so worshiped as gods.
On this day alone, Korean Peacock discovered an ancestral elephant and a Deinodon, and later discovered a Stegodon. It can be said that the ancestors of several elephants have been discovered here.
Among them, the earliest and most primitive one is the ancestral elephant. The ancestral elephant developed along three directions. One branch was Deinophorus, the other was brachy-jawed mastodon. The third branch passed through the stages of long-jawed mastodon, saber-toothed elephant, etc., and finally evolved into
Modern icon.
This time Han Peacock was well prepared, so he brought many huge refrigerators and lifting equipment.
With these preparations, whenever a discovery is made, it can be dug out and stored immediately.
In addition to the ancestor elephant, the second one to be excavated was a Deinodon. This Deinodon was more than five meters tall and weighed more than ten tons including the ice that wrapped it.
After most of the ice cubes outside its body were removed, the huge body of the Deinodon was revealed. At this time, Han Kongque and others discovered that the Deinodon was like an elephant placed in the refrigerator, even with its eyes.
All are well preserved.
After careful inspection, Han Peacock discovered that the Deinodon did not have huge tusks, but its mandible had a pair of large downward-curving teeth, and the crowns of the cheek teeth were composed of two pointed ridges.
Han Peacock knew that Deinodon was a special offshoot from the original type of elephant. It once lived in Eurasia and Africa, from its emergence in the early Miocene to its extinction in the Pleistocene. Unexpectedly, it was also found here.
A branch of this ancestral elephant was discovered.
However, in what era did this Deinodon live, and whether it lived in the same era as the ancestral elephant or mammoth, this still needs to be studied.
Han Peacock guessed that these creatures trapped in these ice caves probably lived in different eras because they required different external conditions.
The most important difference is the difference between woolly mammoths and ancestral elephants. One has thick long hair to keep out the cold, and the other is smooth and hairless, and is an ancestor of elephants that lives in the water. If they appear together in one place, it can only prove that
The environment of this place used to be vastly different.
As huge creatures were discovered one after another, Yu Shan slowly learned about the situation here. The changes from tropical rain forests to extremely cold Arctic are the climate changes in Siberia.
During this extremely long period, the Archeopteryx, Deinodon, Woolly Mammoth, etc. all evolved naturally here.
This evolutionary process has been preserved because of the natural icehouse underground, allowing Korean peacocks to witness the entire process of their evolution.
For example, a mastodon discovered by Han Peacock is a direct descendant of the Archeopteryx. The first one to appear was the ancient mastodon distributed in Africa in the early Oligocene Epoch. Its body was twice as large as the Archeopteryx, and its upper incisors further developed, becoming a continuous
Long, downward-curving tusks.
The mastodon's ivory enamel layer is limited to the outside of the tooth. The molars have three transverse ridges. All molars are used at the same time, rather than growing and using one after another.
But here, the mastodon discovered by Han Peacock is not one, nor is it a species, including long-jawed mastodon and short-jawed mastodon.
The jaws, especially the mandible, of the long-jawed mastodon, represented by the codon and the sertodon, are relatively long, and the tips of the cheek teeth become blunt milk teeth, so they are easy to recognize.
The jaws of the brachygnathous mastodon represented by the yokedont were short, and the cusps on the cheek teeth did not form obvious papillae shapes, but instead had many small cusps connected together to form "ridge-shaped teeth."
In addition to these, there are also vertebrates, which are proboscideans between long-jawed mastodons and primitive elephants. They are further developed from mastodons. The number of deciduous teeth on the molars increases, and they are arranged in the same horizontal row.
The mastoid processes on the upper body are connected and develop into transverse ridges.
In addition to these species, the largest number is Stegodon. Later, Stegodon appeared in the Pliocene and Pleistocene, and more are found here.
The body of the saber-toothed elephant is huge, the limbs are very long, the skull is tall, the teeth on the upper jaw are long and curved, the lower jaw is short and toothless, the molars are greatly elongated, and there are many low transverse ridges on the crown of each molar tooth.
Looking at these ancient elephants, Han Peacock seemed to have seen the evolutionary history of the entire elephant family, including all kinds of elephants, until the end of the last mammoth.
Among them are only saber-toothed elephants. Han Peacock discovered several species. The reason why he recognized the differences between these types of saber-toothed elephants was entirely because such saber-toothed elephants were also found in China.
my country's saber-toothed elephants appeared in the early Pliocene and were still widely distributed in the middle of the Pleistocene.
So far, 8 species have been discovered, including the famous early Pleistocene Stegodon sangii in Yushe, Shanxi, the Early Pleistocene Pre-Oriental Stegodon in Liucheng, Guangxi, the Middle Pleistocene Oriental Stegodon in the provinces south of the Yangtze River, and the
The early Pleistocene Yellow River elephant discovered in Heshui County, etc.
It is with the comparison of these saber-toothed elephants that the Korean peacock can be accurately classified. This is because the Korean peacock has a strong memory, so it can be accurately classified. Otherwise, just identifying these behemoths would be a very troublesome thing.
Of course, when dealing with elephants of various eras and types, Korean Peacock also had some unexpected surprises, such as a saber-toothed tiger.
The saber-toothed cat found here is a short saber-toothed cat in the subfamily Sabretoothinae. It is a side branch of the evolution of large cats and lived in the Miocene and Pleistocene periods.
This saber-toothed tiger was very complete. Perhaps it accidentally fell into the icehouse and could not climb up, so it finally froze to death here.
This saber-toothed tiger has a pair of canine teeth that are longer than other cats, but much smaller than the saber-toothed tiger's saber teeth.
Most members of the saber-toothed subfamily prey on large herbivores, and whether they are Archeopteryx or Deinodon, they are probably the prey of saber-toothed cats.
The injured mammoth that Han Peacock discovered earlier was probably a wound left after being attacked by a similar large carnivore.
With climate change, most herbivores have moved south, which may be the reason for the extinction of saber-toothed tigers.
After discovering a saber-toothed tiger, Han Peacock started a new round of search. However, after discovering the vomiting saber-toothed tiger, no matter how Han Peacock searched, he found no trace of the saber-toothed tiger again.
This makes Korean Peacock very disappointed. In the United States, thousands of saber-toothed tiger fossils were found at one time, but why are there not so many here?
However, in the process, Han Peacock discovered the remains of many ancient elephants, but the total number of various deinodons, saber-toothed elephants, archelephant and mammoths did not exceed one hundred.
Therefore, the ancient biological cemetery discovered by Han Peacock here is not the best. You must know that La Brea Farm in urban Los Angeles, USA, is one of the most unusual fossil sites in the world. Two thousand fossils were discovered there.
Compared with the fossils of Smilodon, a relative of saber-toothed cats, the discovery of Han Peacock is weak.
"Boss, boss, come and take a look!" Just when Han Peacock was a little disappointed, he heard Huangshan's shouting.
However, when Han Peacock heard this shout, his mood immediately improved. He must have made a surprising discovery, so Huangshan was so excited.
"What's wrong? What did you find? It's not like you discovered thousands of saber-toothed tigers at once, right?" Han Peacock said with a smile.
Huangshan's smile faltered, but he quickly recovered.
"Boss, let's take a look for yourself!" Huangshan moved away, allowing Han Kongqueke to see a small piece of ice.
There was a dark patch inside the ice cube, and Han Peacock didn't recognize it for a moment.
"Another ancestral elephant? It doesn't look like it! This guy seems to have fur, and at a glance it looks like a big fox." Han Peacock took a closer look and immediately saw what it was.
"Is a bear worth your fuss?" After seeing clearly the animal sealed in the ice, Han Peacock was a little disappointed, because it looked like both a fox and a black bear. After all, it was not small, so it was impossible
It's a fox.
"Boss, take a closer look, is this a black bear?" Huangshan is still smiling, which makes Han Peacock look surprised.
However, Huangshan's performance made Han Peacock excited. Could it be a close relative of the black bear? And what are the close relatives of the black bear?
"This is a national treasure? How could the remains of a panda appear here?" Han Peacock stared at the frozen giant panda in disbelief.
"Giant pandas have lived on the earth for more than 8 million years. They have lived on the earth much earlier than humans. It shouldn't be surprising to discover giant pandas, right?" Mu Ling said.
Han Peacock thought for a moment, nodded and said: "It's not surprising, but in the middle of the Pleistocene 600,000 years ago, the development of giant pandas reached the peak of their population, but they were widely distributed in southern China.
The central part, the west, and north to today's Hebei Province form the 'giant panda-stegodon community'.
Animals of its contemporaries have basically become extinct due to strong geological and climatic disturbances, such as saber-toothed elephants and saber-toothed tigers, which have all become fossils. However, giant pandas can survive in harsh natural environments.
Giant pandas can survive mainly because they change themselves in the changing environment, so they have not disappeared from the chain of the biosphere, thus becoming one of the few living fossils of animals in the world."
This is natural selection. The giant pandas adapted to the changes in the environment, so they migrated from north to south to modern tropical areas. However, the saber-toothed tigers and saber-toothed elephants that could not adapt to the environment all perished. (~^~)
