On what basis do scientists infer how the Yellow River elephant became a fossil in the Yellow River

The Yellow River elephant is the world's best-preserved elephant and the largest elephant fossil ever found in Asia, with a height of meters and a total skeleton length (the drooping part of the incisors from the base to the tail). It is also the most well-preserved elephant fossil found in the world, and the skeleton of its whole body is only the hanging tail that has not been found. Scientists have analyzed that it may have left its tail exposed when it sank into the sediment, so it decomposed and was not preserved as a fossil.

Summary. Hello, it is a pleasure to tutor your studies.

This part of the text is the focus of the text, and the fourth natural paragraph is particularly important, especially to guide students to give full play to their imagination and vividly express the scene of the old elephant falling into the mud.

What exactly is the scenario described in the fourth paragraph of the Yellow River Elephant, and what is the basis for such a scientist's assumption?

Hello, it is a pleasure to come and tutor you in your good macro study. This part of the content is the focus of the feast book, and the fourth natural paragraph is particularly important, especially to guide students to give full play to their imagination and vividly imitate the scene of the old elephant falling into the mud.

The reason why the fossil bones of the Yellow River elephant have been preserved is that the Yellow River elephant was buried in the ground and has not been moved, and has become a fossil. This is formed by geological conditions. 2. Protect it during the excavation process of noisy scientists. This is facilitated by social conditions.

The reason why the Yellow River elephant has not been moved is that the earth's crust has changed after the Yellow River elephant has been stuck in the quagmire. This is generated by natural conditions.

What questions can be asked in the lesson "The Elephant of the Yellow River"?

Hello, dear, according to the question you described, the tutor answered the following questions: Questions: (1) A group of Yellow River elephants ran to the small river due to fatigue and thirst.

Those scenes highlight ( )2) that the herd of Yuanmin elephants is in action, led by the elderly bull elephants, so it runs at the front. and (3) how it got stuck in the mud. Because the mud is rotten and soft, and it is also very thick, the whole elephant can sink into it.

4) Why only one elephant is trapped. (5) How did he die, he fell into the mud and poured a lot of water. (6) How to become a fossil.

Summary. Question 3: Why are the "dinosaurs" that originated from birds similar to the real small theropod dinosaurs in terms of structure and habits? A ornithologist explains that this is because of those birds that became on land.

After running on the raptor, due to the similar living environment to small theropod dinosaurs, it is in the body structure. They have evolved many functional structures adapted to life on land, making people mistakenly think that they are dinosaurs, but in fact they are still fake birds.

What questions can be asked in the lesson "The Elephant of the Yellow River"?

1. Question: What technique is used in the text "The Elephant of the Yellow River"? 2.Q: How do scientists imagine the fossilized bones of the Yellow River elephants? What are the changes in their roots, such as the closed ones?

3 What are the characteristics of the fossilized bones of the Yellow River elephants?

1. Question: What technique is used in the text "The Elephant of the Yellow River"? 2.Q: How do scientists imagine the fossilized bones of the Yellow River elephants? What are the changes in their roots, such as the closed ones?

Pro: Is there any problem.

I've got three questions for you to refer to.

Oh good. The first question answer text uses the rhetorical devices such as column numbers and metaphors The second question answer answers: The roots of scientific math collaborators are:

1.The fossilized bones of the Yellow River elephant are complete; 2.Standing in front of the skeleton of the spine god, it seemed that he saw the Yellow River elephant running; 3.

The skeleton is stuck diagonally in the sand, and its feet are on the stones.

The answer to the third question is tall and complete, vivid and realistic.

Thank you. Birds don't recognize dinosaurs as their ancestors and ask questions that they don't understand.

Three questions, three answers.

Take a picture and post the text.

I can't find this article.

Question 1: How many categories are there about the origin of birds? Answer: Two, the dinosaur pie and the groove tooth pie.

Problem 2: Birds and reptiles have lungs that have 20 times the oxygen demand of birds that are 20 times higher than those of reptiles of the same size, which means that the lungs of birds are very powerful, have an air sac-like structure, and are able to exchange gases efficiently.

Question 3: Why are the "dinosaurs" that originated from birds similar to the real small theropod dinosaurs? A ornithologist explains that this is because of those birds that became on land. After running on the raptor, due to the similar living environment to small theropod dinosaurs, it is in the body structure.

They have also tended to be the latter, and have evolved many functional structures adapted to terrestrial survival, making people mistakenly think that they are dinosaurs, but in fact they are still fake birds.

It seems that it is impossible to know the origin at all.

Here's how it was corrected: Scientists speculated about the origin of the fossils based on the appearance of the Yellow River elephants.
