I think it may be because human fossils are relatively small, so they are not easy to find, and the formation of fossils requires certain conditions, which are not available in human races.
-
This is because ancient dinosaurs were huge, so dinosaur fossils were also very large and easy to find, while humans were very small. The probability of being discovered is not very high, so fossils of evolved humans have not been found.
-
Dinosaurs used to exist in large numbers, many more than human beings in the past, and human beings experienced ice ages, and in many periods, there were only a few thousand people, and it was difficult to become fossils.
-
It's scary to think about! Dinosaur fossils are being unearthed one after another, but why can't we find evolving human fossils?
-
It was formed after about 10,000 years, because it can only be formed after a relatively long period of precipitation, and because the age in which he lived is long away from us.
-
Hundreds of millions of years, because the age of dinosaurs has passed a long time now.
-
It has been at least 10,000 years or so, and the time is very long, and the preservation is relatively complete, which is very valuable for research.
-
The first dinosaur bone fossil was discovered and collected in 1677 by Robert Prout, a conservator at the Oxford Museum in England.
When the dinosaur died and was quickly covered with sediment or underwater sediment, the petrification process began.
These sediments contain fine particles that create a soft covering on the surface of the body. This blanket protects the carcass from scavengers, as well as inhibits the decomposition of microorganisms by insulating oxygen.

Come to Yunnan, Lufeng World Dinosaur Valley, there are dinosaur group fossils, the largest dinosaur fossils found in the world.
-
The first fossil was discovered in 1822.

The time of the two is not the same, the dinosaurs on the earth first appeared 100 million years ago, and when they became extinct in 65 million years, they had lived on the earth for hundreds of millions of years, and in the time of ruling the earth for more than 100 million years, the dinosaur family reproduced a large number of descendants, and because of the large number, there are many probabilities to form fossils or even complete dinosaur fossils. On the other hand, human beings, although the great apes that evolved into humans appeared as early as 30 million years ago, but the real ancestor of human beings, Australopithecus, lived on the earth for less than 2 million years, and in such a short period of time, the number of human families is not much, the probability of forming fossils is much smaller, and the probability of forming complete human fossils is even lower, so although archaeologists have also found human fossils, there are not many of them, and they are all fossils of a certain part of the human body, such as skulls.
2.Secondly, the reason for the huge difference between the number of dinosaur fossils and human fossils is also because the environment in which the two live is different, the ancestor of human beings, Australopithecus man, often lives in mountainous areas, hills, plateaus and other areas with complex terrain, in order to prevent wild beast attacks, living in these areas is safer, but it also brings a problem, that is, these areas cause the bones of australopithecus to be buried deep enough, because the depth is not enough, the remains will disappear without a trace after thousands of years of feng shui rain. Most of the dinosaurs lived in plains, basins and other sedimentary areas that are easy to be submerged, and these sedimentation areas will be buried deep underground with the movement of the earth's crust, so as to preserve the integrity of dinosaur fossils to the greatest extent, which is also the main reason for the large number of dinosaur fossils.

After the death of the dinosaur, if it was not eaten by other animals, but was quickly buried in the ground by the soft sand, then the abundant inorganic salts in the groundwater, such as calcium carbonate, silica, pyrite, etc., were chemically replaced with their bones, and over time, the bones that did not decay in the body were replaced by these inorganic salts to form fossils. But there are few opportunities to meet the conditions for the preservation of these fossils. As a result, very few dinosaur remains can be preserved as fossils.

However, there are few chances of meeting the conditions for the preservation of these fossils. For animal carcasses to form fossils, they must be quickly buried undamaged. Land animals like dinosaurs were easily eaten by scavengers after they died.
Even if not eaten, corpses are prone to decay when exposed to air, and bones can be destroyed by weathering.
On land, only when there happens to be a sandstorm, volcanic eruption, etc., dinosaurs are quickly buried by dust and ash, or dinosaurs happen to die in lakes, rivers, swamps and other environments with better burial conditions, and are quickly buried due to the sedimentation of rivers and lakes, fossils will be formed. As a result, very few dinosaur remains can be preserved as fossils.
At the moment, cloning technology is progressing very slowly, so there is no hope.
I also saw the Qin Dynasty's ipone yesterday, do you want to send it too?
1.It means that the earth is changing a lot.
2.Fossils also contain remnants of living organisms. >>>More
Here's how fossils are formed:
There are two types of fossils, one is formed by the decomposition of the organic part of the body and the petrification of the hard part after the death of the organism on the earth. The other is the traces left by those creatures, which are formed by turning into stone after petrification. It takes hundreds of millions of years to form and can be divided into plant fossils including roots and leaves, and animal fossils including teeth and footprints. >>>More
Summary. 1: Biological variety:
Common creatures such as trilobites, sea shells, sea snails, late fish, etc., are common creatures, and such fossils are not valuable. In general, human fossils are worth more than plant fossils, plant fossils are worth more than insect fossils, insect fossils are worth more than animal fossils, and animal fossils are worth more than sea creature fossils. >>>More
