Chapter 722: Evolved Dinosaurs (Anti-theft Chapter)

Yun Lei smiled: "Most of the dinosaurs in "Jurassic Park" are smooth-skinned. This is a scientist from a few decades ago, based on the fact that dinosaurs were cold-blooded animals and were related to snakes, crocodiles, turtles, etc. But in reality, there were many dinosaurs with feathers. ”

"An international team led by Chinese scientists found a specimen nearly four centimeters long, containing eight vertebrae and feathers, in a piece of amber found from Bagan. ”

"Unlike the bird's ancestor, Archaeopteryx, as well as modern birds, these vertebrae do not fuse at the end of the tail, but are more like a flexible whip that bends in multiple places at once. Scientists generally believe that this specimen should come from the tail of a small bipedal dinosaur, and that amber was formed about 99 million years ago. ”

"There are many different types of theropod dinosaurs such as Chinese dragon birds, tail feather dragons, and microraptors in the Early Cretaceous strata in western Liaoning, China, and there are many different types of feathers preserved on the fossils. ”

"Based on the evidence from these fossils, theropods that are biologically closely related to birds should have had feathers or feather-like structures. Dinosaurs evolved their feathers before they evolved their wings. ”

And without this assumption, even dinosaurs that are not closely related to birds should have feathers, or full of feathers. ”

"A new species of feathered dinosaur found in southern Prussia, covered with fine filamentous feathers. The fossil formed by this 150 million-year-old squirrel dinosaur provides the first evidence of a feathered theropod dinosaur that is not closely related to birds. ”

"Because squirrel dinosaurs are very basal in the dinosaur pedigree, it can be shown that all predatory dinosaurs may have had feathers. Including Tyrannosaurus rex. ”

Therefore, many previous popular science materials have been incorrect about Tyrannosaurus rex. The newborn Tyrannosaurus rex should not look like a small snake, but like a fluffy chick without wings......"

"As many scientists have said – everything that has been discovered so far suggests that the characteristics of modern birds are so deep in the evolutionary tree that it would not be surprising if feather-like structures were found in the ancestors of all dinosaurs in the future. ”

Rao Ya found an ugly flying creature from the space frozen by clouds and thunder, and said, "Is this also a bird?"

Yun Lei glanced at the bat-like creature. "This is not a bird, this is a pterodactyl." It is considered a flying reptile evolutionary branch. The wings are derived from the skin membrane located between the sides of the body and the four wing phalanges. ”

"This creature is the first vertebrate animal on earth that can fly. It is a vertebrate, for the first groping of the sky. This kind of evolution of living beings is extremely rare. ”

"Although this dinosaur has not evolved successfully. However, it is also an important living being. Once dominated the skies. At the peak of this species, the Aeolian Pterodactyl and the Hatzigo Pterodactyl, which have the largest wingspan, can both have a wingspan of more than 12 meters! Even the teeth are ten centimeters long!"

As he spoke, Yun Lei measured the pterodactyl that Rao Ya had taken out, which was only the size of a swallow and had only a sharp beak and no sharp teeth, and said, "Looking at the volume of this pterosaur, this should be a reclusive forest pterosaur." The fern trees here are far taller than the low ferns we had when we entered this space before, because of the carbon dioxide emitted by the earth's fire magma, as well as the support of light and heat. ”

"It doesn't depend on fluorescence. And fluorescent mushrooms, in this magma-bright place, have also lost their living space. This reclusive forest pterosaur, although it is not large in size, is not strong in attack. However, because of their small size, they are able to hide their bodies by surviving among such tall trees. Instead, it's appropriate. ”

Yun Lei took out a creature the size of a pheasant with light-colored feathers from among the birds, and said to Rao Ya: "Compared with pterosaurs, this is the most successful dinosaur in evolution. ”

Rao Ya asked, "What is this?"

Yun Lei said: "This is the Archaeopteryx!"

Rao Ya looked at this strange bird that didn't seem to be so flexible when it flew up, but it had four wings, and was surprised: "This is the Archaeopteryx?"

Yun Lei said: "It should be right. In the absence of new and powerful archaeological discoveries, this bird is the ancestor of all modern birds. The future generations are endless. It's just that although the body structure of these four wings looks powerful, it is actually not as suitable for flying as the pair of wings of modern birds. ”

"According to paleontologists, an analysis of the structure of the Archaeopteryx's body. The shoulder blades, rostral bones, and articular sockets between the humerus are located laterally. It is not the arrangement of the horns of the back, as is the case with birds today. ”

"Therefore, when Archaeopteryx is flying, it cannot raise its wings to its back and fly upwards. You can only use the technique of downwards as much as possible to glide. That's why these Archaeopteryx looked so stupid when they flew up just now. ”

When Yun Lei explained to Rao Ya, he selected a few strong and healthy Archaeopteryx, the Reclusive Forest Pterodactyl, and the Bird Dragon in the sky to put into the space gourd.

Then, Yun Lei unlocked the space confinement, and with a wave of his hand, let the imprisoned birds scatter in all directions!

These primitive Archaeopteryx, the hermittent forest pterosaur, and the Okutosaurus, and some primitive birds or dinosaurs that even Yunlei could not recognize, and did not even have fossils in the outside world. He has ever experienced this kind of spatial confinement.

I saw these two guys who didn't have wings on their backs and had feathers all over their bodies. They can't even flap their wings. Grab a few of your kind. But I don't know where to catch it. The little one, even more terrifying, was wreaking havoc on a fluffy fellowship with beautiful feathers.

I felt that the sky bird dragon was almost bald. But he smiled, smiling like a flower, and he didn't even mean to let go.

The birds or dinosaurs scattered in the air. Each flew away.

At this time, Yun Lei felt something. Look in the direction of the birds or dinosaurs flying away. I saw only a few spears and feathered arrows rising into the air. Shoot down a few Archaeopteryx and other birds or dinosaurs!

This barren place, which seems to have never changed from ancient times to the present, is actually inhabited! Yun Lei's heart moved, and suddenly thought of a possibility......
