It's nice to be able to collect, it's a bit pretty.

He is one of the nine sons of the dragon in ancient Han myths and legends, also known as Baxia. It resembles a turtle, is a good load, and carries the stone tablet for many years.

On the one hand, it is a practical thing, used to make a stele base, commonly known as "the turtle camel stele", on the other hand, it has very important cultural significance. Its symbol is based on "longevity and auspiciousness", and carries connotations of status, totem worship, witchcraft worship, etc.

In the ancestral hall of the temple, people can see this hard-working strong man everywhere. It is said that touching it brings blessings.

From ancient times to modern times, it has always had a very important cultural symbolic significance.

1.a symbol of the status of power;

2.A symbol of longevity and auspiciousness, people worship the turtle and have always worshiped it as a symbol of longevity.

3.symbols of regional culture;

4.Totem worship and immortal magic worship are prevalent, representing people's pursuit of immortal magic.

One of the "Nine Sons of the Dragon" is a unique cultural phenomenon in ancient China and the result of thousands of years of precipitation in Chinese civilization. Contemporary people still like to regard the sage as a symbol of longevity and good fortune, for example, many modern temples and cemeteries have rebuilt or well-preserved sends. [1]

There are many interpretations of the swagger: strong and powerful; refers to the appearance of exerting force; dignified appearance, strong appearance; large and heavy-looking; Another name for loggerhead turtles. In the old days, the stone seat under the stele was carved along the side to make a stumbling shape, that is, to take the meaning of its strength and ability to bear the weight; It is used to refer to stone tablets; Load; By extension, it means taking on heavy responsibilities.

We always say "shrunken turtle", as if the turtle shell is the tortoise's golden bell cover iron cloth shirt, which can keep it safe for a lifetime.

However, scientific research has shown that 200 million years ago, turtle ancestors did not evolve turtle shells to make shrunken turtles, they did it for the better - digging in the soil! Shovel the ground! To discuss this issue, we have to start with the evolutionary history of turtle shells.

From the above picture, we can clearly see that unlike the armor of lizards or crocodiles, the most buggy thing about modern turtle shells is that it is closely connected to the internal skeleton of turtles! This allowed the turtle to practice the stunt of "being able to stretch and contract".

For a long time, paleontologists have debated the most important story about this amazing turtle shell. Most paleontologists agree that turtles were similar to lizards from the very beginning, covered with skin and bones (the armor on the surface of the lizard is the skin and bones). The skin and bones then gradually fuse with the internal bones to form a turtle shell.

However, there are also a small number of scientists who insist that the shell is transformed by the expansion of the ribs. (That's right, like people, turtles have ribs.) This endless debate lasted for almost two hundred years.

Finally, in 2008, an archaeological discovery by Chinese scientists made everyone shut up and marveled.

That year, Chinese researchers discovered a 100-million-year-old "half-carapace-toothed turtle" in Guizhou. Turtle fossils found in the past were the same as modern turtles, with their abdomen and back covered with carapaces. And the half-carapace-toothed turtle is a surprise for people:

It has a complete carapace on its belly, but no shell on its back, only a widened dorsal rib, tooThere is no skin bone

So do you understand? This is a turtle that has not yet fully evolved, in a transitional stage! It seems that the minority scientists are rightThe turtle shell is the first to change from the ribs, and has nothing to do with the skin and bones.

A few years later, German scientists discovered a fossil that was 100 million years old - "turtle ancestor", and with its further evidence, scientists finally recovered the evolution of turtle shells: First, the ribs of the turtle's abdomen widened, and the abdominal carapace evolved; Immediately after that, the ribs on the back also widened, evolving into the dorsal armor. This is how the turtle shell is formed.

The shell of the turtle is widened by the ribs of the chest, which evolved into the abdominal carapace, and then the ribs on the back gradually evolved and widened to form the dorsal carapace, which is the process of the formation of the tortoise shell.

The shell of the turtle is its spine, it can't be taken off, it is a part of its body, it will hurt if you knock the shell, it is a shell on the turtle's back that protects the turtle from harm.

The shell of the turtle is actually the ribs of the turtle, and according to the research of scientists, the turtle has evolved from before, and their ribs have been widening and slowly turning into tortoise shells.

What does the turtle look like and what does it look like:1. The tortoise shell of the tortoise is like a bunker during a defensive war, and it is like a small house on its back.

2. The turtle is like a stone with a pattern, and it is like a protective shield on the battlefield.

3. The turtle's movements are slow, like a toddler old man, and like a child who has just learned to walk.
