Scientists accidentally discovered a small dinosaur fossil when they discovered the original dragon"s nest. What does it do to run into the nest of the original horned dragon? After research, it turned out to be a small bad guy who specializes in stealing dinosaur eggs. It has no teeth in its mouth and has a spike that is the tool it uses to pierce and absorb the egg juice. The dinosaurs on land are the ones we are most familiar with, perhaps because their bone fossils are more easily preserved.
There are many such dinosaurs found today, such as the beast dragons, such as the toothed dragon; the stegosaurus, such as the stegosaurus; the ankylosaurus, such as the forest dragon; the horned dragon, such as the triceratops; the brontosaurus, such as the brontosaurus, etc. Wait. Apatosaurus is a fierce and terrible carnivorous dinosaur with a big mouth that can swallow a pig at once. Its teeth are all bent inward, and the prey is bitten by it and then wants to escape.
When the original horned dragon is laying eggs, it is often a couple of female dragons sharing a nest. Everyone takes turns to make a circle of real eggs. It seems that they are very united. The Triceratops is a kind of horned dragon. It has a horn on its nose, like a rhinoceros, with two horns on its eyes and a cow.
These three corners are all 1 meter long and are a powerful weapon for them to fight. On the head of the dragon, there is a striking tube with a thin passage inside. When the air passes, it will make a low sound, which can be used to scare off the enemy. It is also believed that it is used for ventilation during diving. What is it used for? It is still inconclusive.
This is a kind of ankylosaurus, their skin is very hard, like armor. The body and the tail are spurs, like the mace, no one dares to touch them. The brontosaurus is the largest of the dinosaurs, some of which are more than 30 meters long and 6 stories tall. They are animals that eat grass or leaves. Some dinosaur fossils we have seen in museums are mostly such dinosaurs.
About 200 million years ago, geological history began to enter the Mesozoic. At this time, dinosaurs appeared on the earth. In the next 100 million years, the family of dinosaurs is getting bigger and bigger. Later, they seemed to disappear suddenly in a day, leaving us with countless mysteries.
After the unremitting exploration of the scientists, we gradually got some understanding of the dinosaurs. Although the dinosaurs were big, stupid and terrifying, their stories are quite interesting. The story of the mother-in-law: In the past, people always thought that dinosaurs, like today"s reptiles, walked away in their lifetime, regardless of their children.
Later, the scientists found that the teeth of some young dinosaur fossils had obvious signs of wear, indicating that it had begun to eat. However, the limbs of these young dragons have not yet fully developed, and it is clear that they have not begun to crawl in the true sense. It seems that the baby dragon is raised by the parents in the nest.
In addition, the analysis of dinosaur footprint fossils shows that they often line out, the big dinosaurs are on the sides, and the small dinosaurs are in the middle of the queue, just like the elephants we see today. So the scientist gave the dinosaur a very human name, the mother dragon. However, many people believe that this evidence alone does not prove that dinosaurs are descendants of purposeful raising. Because no reptiles in the world have shown such love.
The crocodile is the best, but it is just a small crocodile with a mouth out of the mouth, bringing them to the water, even if the task is completed, as for the small crocodile will swim, can not pray, it does not matter. Each time, the mother-in-law can produce 25 eggs. These 25 small dinosaurs eat a few hundred pounds of fresh plants every day. The mother-in-law needs to work tirelessly to find food. If this is the case, they are worthy of the title of the mother.
When people first discovered the Stegosaurus, they noticed that they had many bone plates on their backs. Initially, scientists estimated that these bone plates were laid flat on the dinosaur-like cover. Later, after careful investigation, it was finally determined that the bone plate was erected. These bone plates are filled with voids and there are many grooves on the surface.
These gaps and grooves are filled with blood. When the temperature is lowered, the Stegosaurus will open the bone plate and absorb the heat of the sun. When the temperature rises, the bone plate will be turned and the cool air will be used to dissipate heat. Stegosaurus"s head is very small, and the brain is only the size of a walnut. It is not commensurate with its huge body. Scientists have determined that the stegosaurus must be stupid.
