The first three types of flying dragons and earth dragons ......

Shield Dragon...... It's better to plant a mechanical dragon.

Those who study defense-related specialized labels are called armored dragons or shield dragons.

Those who study specialized tags related to attacks are called bladed dragons.

If you really need to specialize in the evolution of a dinosaur that specializes in the production of materials, then it is called the Physaurus species.

Or, specialize in an evolutionary branch that can make use of a variety of materials.

Armored and Bladed Dragons' specialized appendages, which can be used if they molt or die in battle.

Although the local industry feels that it is risky to rely on foreign objects, it is not bad to use the relevant labels of foreign objects, if any, to integrate one.

After that, there are still a few directions that Dixing wants to study.

There are flight-related, ground-related, and the sea, land and air are different.

Even if you don't plan to live in the ocean for a long time, you need to use it if you need to fight in the sea or take refuge for a while.

And there are too many races related to the water environment.

Needless to say, arthropods, although they have withdrawn from the ranks of hegemons, still occupy ecological niches on land, sea and air.

Then there are all kinds of ancient and modern birds, whether they are (non-bird) dinosaurs or birds or reptiles, and there are a large number of cases of attempts to enter the water, such as Thornthra, the famous fisherman.

Among the ancient and modern birds, there are specialized populations such as penguins that have survived to this day due to high water environmental dependence, and early explorers such as twilight birds.

However, reptiles are more well-known than dinosaurs, a taxonomic group of sauroplasms that integrate with the exception of (non-orniven) dinosaurs and birds.

Lizards are only divided into existing organisms, that is, reptiles and birds, and if you refine them, you can continue to decompose reptiles.

According to the habit of paleontological classification, the group of paleontologists of the sauromorphs can be divided into the main dragon and the scale dragon, to be precise, the main dragon morphology, and there are only crocodiles and birds in existence.

Members of extant reptiles, beaks, turtles, earthworms, lizards, snakes, and crocodiles.

The Lepidosaurus includes all members of the extant reptiles, except crocodiles.

As for turtles and turtles, because of the lack of fossil transitions in the early days, this group of guys has not been easy to distinguish, and the paleontological classification is also quite tortuous.

Some put it in Lepidsaurus, and some even had groups of people at first divide it into sister groups of mammals.

Later, it became clear that the fossil was a major dinosaur morphomorph, but it was not certain whether it was a main dinosaur.

To put it simply, the main dragon morphology includes the main dragon morphology.

Instead of discussing phylogenetics, only the concept of appearance and morphology is discussed, just like "humanoids" and "humans", the main dragon morphology is equivalent to humanoids, and the main dragon is equivalent to humans.

Until the earth traveled to this world, there were two main versions of turtles and turtles.

One is classified as a "pan-turtle class", represented by turtles and turtles, including plesiosaurs, etc., which belong to this branch, which is the same generation as the scale dragon and the main dragon, and belongs to the sister group of the scale dragon and the main dragon.

One is to be divided into the main dragon form class, and the main dragon form class as a sister group.

Of course, there are still some people who think that it should be classified under the scale dragons, and this supporter is relatively small.

Speaking of which, you should look for fossils that resemble turtles, whether they are southern-minded turtles or semi-carapace-toothed turtles, proto-beaked turtles, protojawed turtles or other turtles, all of which have a certain amount of excavation ability.

The reason why ankylosaurs were always considered to be burrowing at the beginning seems to be related to the characteristics of turtles that evolved to lower the center of gravity and are suitable for digging.

As for the group of turtles with their names, who of them is the real turtle ancestor, Di Xing doesn't know, but he knows that most of the turtle brothers are specialized in the direction of defense.

Of course, there is also specialization in the direction of attack.

Occlusion-related specialization.

The fourth category that the earth line is preparing to make is tentatively designated as the sea dragon species.

All species are centred on water-related labels.

The subordinate branch, the first one mainly studies occlusal attacks, takes crocodiles and various sea crawlers as the main reference direction, obtains their relevant tags, and then carries out the evolution of the fantasy direction.

The bite force of crocodiles is indeed very strong, but there are also major drawbacks.

He needs bite force, but these flaws need to be addressed.

The second, on the other hand, is based on completely underwater creatures, focusing on agility related to swimming speed, taking into account bites and other attacks.

Just as in the Wyvern species, the Earth Walk also considered the question of which branch of the Wyvern should develop flight speed, and here it is also necessary to consider speed, whether it is to pursue, escape or migrate.

The third branch considers amphibious or even tribious in the real sense, although all kinds of sea crawlers live in the sea, they actually breathe air, which can only be said to be "diving".

However, as mentioned earlier, due to the limited relationship of resources, there is often a conflict between generalization and specialization.

It is always said that all-round reinforcement is all-round strengthening, but resources are limited, and to strengthen in all directions, resources need to be spent in all directions, although there is an overall effect - the overall improvement will reduce the difficulty of one-way improvement, which can also be compared with the word "touch bypass".

If you only break through one direction, it will be more and more difficult, and you will need more resources and less efficient if you continue to move forward.

Or it can be compared to bamboo poles and pyramids.

The pyramid made up of bamboo poles requires more resources, but a certain amount of heaping can replace the heap.

A bamboo pole, five centimeters and ten centimeters is no problem, and five meters and ten meters is not a big problem, but what about five hundred meters and five thousand meters high, can the material hold up?

In the case of pyramids, the same structural strength can be used to replace the strength of the material itself.

In the early and middle periods, of course, the height that bamboo poles can reach is high, but in the later period, it is not comparable to the pyramids.

The analogy should be relatively simple and easy to understand.

It's just that, despite the existence of this effect, it is also limited, and the self-weight itself is also a big problem, otherwise he would not have specifically engaged in a mountain dragon species to study the related problems of structural support.

The ground bank decided to engage in two amphibious, one is water and ground amphibious, and the other is water and air amphibious.

Amphibious focuses on the body, studying what kind of body structure is suitable for both land and water.

However, the amphibians of the previous life, themselves a transitional group, are often more than the upper than the lower.

The most successful amphibians today are frogs.

He had an idea, though.

As mentioned earlier, amphibian, why is it called amphibious, the most important thing is the respiratory organs, or ......

Organs involved in energy conversion.

What if, oxygen is not needed?

Not to mention the use of other substances, anaerobic exercise may be a direction that can be considered.

Whether the oxygen concentration is sufficient or not, it can be converted into energy that the body can use.

In other words, in addition to the fluid adaptation structure of the body's streamlines, this branch also has the task of studying the way of breathing and energy utilization.

As the fourth branch, the body is also an important factor, but structurally he considers the direction of wings and tail.

The wings are mainly used to fly, and the tail has a relatively small role during flight.

But underwater, the role of the tail is sometimes more important than the forelimbs.

He needs to try this.

There are not too many seabirds that can be used for reference, as well as flying fish that can jump from the sea and fly hundreds of meters above the surface of the water.

And, just like the previous third, he also has to think about how energy is generated and utilized.

Aerobic and anaerobic respiration have a nearly twenty-fold efficiency ratio.

But...... There are also various types of anaerobic respiration, there is lactic acid, there is also alcohol, such as yeast, and the anaerobic reaction can produce alcohol as a fuel, and this by-product may be able to be used if you need to breathe fire.

In the fantasy world, there may be other materials to consider in terms of energy.

Of course, the fifth, a direct "sea, land and air" three-purpose model, of course, is also needed, after all, it will have to go in the end, but it is very difficult at first glance.

If you really can't do integrated casting, then use separate parts to assemble.

As for the naming aspect.

The first bite is specialized, not very good, directly referred to by the crocodile of the crocodile, the crocodile species is no problem, but he is more inclined to bring mouth, teeth, and words related to eating imagery, what kind of dragon species, jaw dragon species, the former sounds like a kind of special dragon eating dinosaur feeling, or jaw dragon species, simple and clear.

The second aquatic swimming specialization, called simple and clear, can also use ichthyosaur species, if you want to look fierce, you can also bring the image of sharks, called shark species.

The third branch of amphibious specialization, or energy and fluid adaptation specialization, and at the same time involving water and land single words, most of them are mud, swamps, beaches, and the like.

When it comes to anaerobic reactions and alcohol-based fuels, you can also think of such things as biogas, or you can call it a swamp dragon.

The fourth branch of water and air amphibious specialization, there is no very good single word to use, is it difficult to call it "rain dragon species"?

When it comes to both water and air, it is probably a variety of meteorological-related words.

And, speaking of which, there is a discussion about how a dragon can fly without wings.

Either it can be very fast, like a rocket, or it can be lightweight.

How can you get weight lightly?

Led Zeppelins and hot air balloons can be used as analogies.

The body is filled with all kinds of gases that are lighter than air.

There is a kind of brain hole that is "atmospheric creatures".

There is a kind of brain hole body material that is extremely strong, and there are means to extract the gas from the body and a tight enough airtightness to allow the inside of the body to be directly pumped into a vacuum, and float up while not being crushed by atmospheric pressure.

At the same time plus various means of lift.

Needless to say, of course, the movement lift in the fantasy world......

Any magic, wind element, fire element, can be considered.

But the earth line doesn't need to do this, he will directly have a wing, and it is not known if he can get extra limbs to get the right wings on his back, but the winged hand is at least feasible.

The name is put aside for now.

The fifth water, land and air amphibious specialization, the same, there is no good name to use.

In addition to this, he has several types of directions.

The fifth group, such as the royal rex species that includes a variety of social animals as the direction of evolution, including lions, wolves, humans, ant colonies, and bee colonies, etc., specializes in the study of group labels.

After all, it is not feasible to go it alone, and you can use it if you can.

The sixth category, there is also the direction of evolution of mollusks, mainly studying muscle structure and restorative specialization, and obtaining relevant labels, "soft dragon" or something is not good, or it is called "blood dragon species", hearing blood, you can often associate it with life.

There is also a seventh category, which takes echinoderms as the evolutionary direction and focuses on ...... The main "heterogeneous", all kinds of unconventional, bizarre, and even remove the brain, restore to the early neural structure, even the type without neural structure, you can also try, in short, the core idea is a bold.

As for what it's called...... It's called the dragon planted.

ps: If you continue to expand, it's too much, just stop here, and if there will be [X dragon species] or something in the future, I won't go into details.
