Are dinosaurs and birds an ancestor, and what is the relationship between dinosaurs and birds?

Birds evolved from dinosaurs.

The following quotation: As early as 130 years ago, one of the supporters of Darwin's "evolutionary theory", Jujube Huxley, put forward the idea that birds evolved from dinosaurs, and for a period of time, this academic view was not accepted, but in the last decades of this century, this statement was almost tacitly acquiesced by peers, therefore, through the specimen of "Chinese dragon bird", it reflects the extremely similar characteristics and subtle differences that exist between dinosaurs and birds, and further supports the view of "the origin of dinosaurs in birds". Not only that, but dinosaurs with feathers such as the primitive Archaeopteryx, the Accidental Beipiosaurus, and the Tail Feather Bird have also been excavated in western Liaoning, China, which further illustrates that feathered vertebrates do not necessarily refer to birds, and dinosaurs also have this characteristic.

The debate about whether the "Chinese dragon bird" is a dragon or a bird, it is time to stop, it is dinosaurs must be undoubted, the key is to provide evidence for the evolution of dinosaurs to birds, if birds are directly evolved from dinosaurs, then, another new theory will be born: dinosaurs are not extinct. The birds that fly in the blue sky now are the descendants of the dinosaurs!

The bird evolved from the American osprey.

Birds evolved from a branch of dinosaurs.

Dinosaurs do have a relationship with birds. Much evidence has been shown that birds evolved from small dinosaurs, and that birds are descendants of dinosaurs. As early as the 19th century, fossils of birds and dinosaurs were found in Germany, which is the fossil of "Archaeopteryx", and people have long speculated that birds evolved from dinosaurs.

Dinosaurs and birds have a lot in common. 1. Bones: There are many similarities between dinosaurs and birds, at least more than 100 kinds, and there are many of them, which are unique to birds and dinosaurs, and cannot be found in other animals, so this bone form provides good evidence for birds and dinosaurs to have close relatives.

2. Behavior: Oviraptosaurus behaves like birds, and the relationship between small theropod dinosaurs and birds is very close from zoology. 3, Feathers:

In small, flightless dinosaurs, the development of feathers was first done to keep warm, and it appeared significantly earlier than the flight of birds. The comparison of dinosaur and bird fossils also confirms that dinosaurs and birds have a certain relationship.

1. There is a very close relationship between dinosaurs and birds. For example, small theropod dinosaurs are not only small in size, but also very similar in shape to birds. Most paleontologists now believe that birds evolved from these dinosaurs.

In 1996 and 1997, several vertebrate fossil specimens were discovered in the Sihetun area of Beipiao, Liaoning Province, China, which shocked the world. Researchers classified it as a bird, the Chinese dragon bird and Archaeopteryx, which later attracted the world's attention. Paleontologists further studied the Chinese dragon bird and found that it was actually a relatively primitive small theropod dinosaur.

2. Studies have proved that Archaeopteryx is actually a small theropod dinosaur, but its form is closer to that of birds than that of the Chinese dragon bird. British paleontology.

There is a saying that birds are descendants of dinosaurs, which means that birds are modern dinosaurs. There was a dinosaur that looked like a bird and slowly evolved into Archaeopteryx, but it was not the same as a pterosaur. It evolved into the current pigeon.

Similarities between dinosaurs and birds: Some dinosaurs had bony tails, sharp claws, beaks, and some even had feathers. Feathers are the main similarity between dinosaurs and birds.

The dinosaur fossil has many similar features to birds, with a large head on a thin neck, a short chest, and arms folded inwards at the sides, exactly the same as a bird's wings at rest.

Much evidence has been shown that birds evolved from some kind of small dinosaur, and birds are descendants of dinosaurs.

There is a close kinship between them.

The Yaolongs and Dendrisaurs, which are found in our country, are the ancestors of birds. When the Archaeopteryx fossil was first discovered, there was a controversy about whether Archaeopteryx was a bird or a dragon, but the lack of fossil evidence failed to overturn it, and the discovery of Zheng's Xiaotinglong completely classified Archaeopteryx as a dinosaur, and Archaeopteryx was the ancestor of the Velociraptor rex, not the ancestor of birds. But Archaeopteryx was an offshoot of the evolution of dinosaurs into birds.

During the Cretaceous period, the evolution of birds also diverged, with the emergence of anti-birds and modern birds. Anti-birds climbed the trees, and now the birds remain on the ground. By the late Cretaceous period, arboreal dinosaurs and anti-birds went extinct along with dinosaurs, but today's birds, which were not dominant in evolution, evolved into today's birds.

Dinosaurs and birds are related by blood, which can be seen from the dinosaur fossils found around the world, such as the Chinese ornithosaurus, the Chinese bird, the Confucius bird, and the Liaoning bird.

I've been suffering from the handsomeness and wit that shouldn't be there at this age, I'm so tired and envious that you are so happy to live without anything, and I'm young and promising, but full of troubles. Everyone praises me for being handsome, and I don't have anything to be proud of, I just happen to cater to contemporary aesthetics and make people happy.

A large number of fossils found in western Liaoning prove that birds are living dinosaurs.

In 2009, the "Heck's near-ornithosaurus" was discovered. The front and rear limbs and tail are distributed with flying feathers, the feather shaft is slender, the feathers are symmetrical, the tips are obtuse and rounded, the legs are also feathered, the lower legs are extremely long and suitable for running, and the hind limbs are feathered. It is a species between dinosaurs and Archaeopteryx, and it is clearly arboreal.

In particular, its age is from 100 million to 100 million years ago, which is older than both Archaeopteryx and Golden Wind Bird, indicating that dinosaurs evolved into older nearornithosaurs and then evolved into newer Archaeopteryx and Golden Wind Bird. This further completes the chain of evidence for the evolution of dinosaurs into birds, and this discovery fills the evolutionary gap between dinosaurs and Archaeopteryx. It has a red crest of feathers on its head, which mainly serves as a display.

The ancestors of modern birds are dinosaurs. The more consistent view is that the direct ancestor of birds was a small dinosaur (Ostrom, 1967), and that the pseudocrocodile evolved into the dinosaur species of dinosaurs, and then further evolved into Archaeopteryx, which evolved into new birds.

Archaeopteryx, which was previously thought to be a bird discovered in the Jurassic period, was thought to be a dinosaur in 2004. It is clear from the specimens that have been found that Archaeopteryx had feathers; hindfoot toe-to-toe type; carpal metacarpal and tarsometatarsal healing; Many features such as pelvic structure, clavicle, beak, mandibular joint pattern, and eyes are similar to those of birds.

Dinosaurs are the ancestors of birds, and dinosaurs became extinct about 65 million years ago.

Dinosaurs are carnivores, birds fly, and of course, some dinosaurs can fly too! It's earned, because the birds, they can fly, but just to whom.

Paleontological research has shown that the ancestors of birds were mutated from flying dinosaurs.

Birds are descendants of dinosaurs, and some dragons transform into birds.

Dinosaurs and birds are very close relatives and have the same bones.

Dinosaurs belonged to reptiles, and studies have found that birds evolved from reptiles.

It should be said that it is a kinship.

Dinosaurs are the ancestors of birds, and birds evolved from dinosaurs.

Tired you raise a positive reminder of your self-confidence.

It is said on television that dinosaurs may have been the ancestors of birds.

Birds are descendants of pteropod dinosaurs.

What is the relationship between dinosaurs and birds?

Yes.

The paleontological community believes that Archaeopteryx evolved from small feathered dinosaurs, and they have many forks in the evolutionary tree, and later all kinds of birds evolved from this group of dinosaurs, and even because the protochicken belongs to the bird subclass - chickens, and humans have domesticated the protochicken into domestic chickens, so it can be considered that chickens are also descendants of dinosaurs.

Characteristics of Archaeopteryx.

The size of Archaeopteryx is only the size of a crow, the appearance is both dinosaur-like and bird-like, the head is bird-like, and the whole body is covered with feathers, and it already has the differentiation of primary flight feathers, tail feathers, secondary flight feathers and compound feathers of modern birds. It has 3 sharp claws on its forelimbs.

Archaeopteryx had sharp teeth in its beak that curved backwards. It also has a long tail consisting of 21 caudal vertebrae. Archaeopteryx is weak in flight, and may only be able to glide at low altitudes, and its flying skills can only be compared to that of modern pheasants.

Archaeopteryx (nickname: archaeopteryx) is a small dinosaur that lived in the late Jurassic period, belonging to the order Dinosaurus Descendanta and representing a primitive type of dinosaurs. It was originally thought to be the earliest bird, but it was later discovered that the Confucius bird and the Liaoning bird were born earlier, and the name is the ancient Greek word for "ancient feathers" or "ancient wings".

Paleovertebrates, with a bird-like head, claws and wings, slightly able to fly, have teeth, similar to reptiles, have a long tail (up to twenty tail vertebrae), made up of multiple tail vertebrae, in addition to having bird feathers on its body, it is generally considered to be an intermediate type of reptile to bird, still belonging to dinosaurs, appearing in the Jurassic. (Dictionary of Modern Chinese, 5th Edition, The Commercial Press, 398th printing, Beijing, December 2010).

Archaeopteryx was originally thought to be the ancestor of birds, and is now thought to be a small theropod dinosaur, but instead they were not avian ancestors, but most likely the ancestors of later dinosaurs. It also lived in the early Jurassic period of the Titong Order, about 155 million to 150 million years ago. These specimens are found only in Germany.

The fossils are found in southern Germany, and its German name means "protobird" or "first bird".

There are now 11 fossils classified as Archaeopteryx, which is the only evidence of feathering from the Jurassic period. Moreover, due to their advanced nature and orientation, it can be seen that their origins are much earlier. Most of the remains are believed to have come from independent specimens.

Hello, the ancestors of dinosaurs were birds, which is a widely recognized scientific opinion. According to research, dinosaurs and birds have a close relationship and they share the same ancestor. The relationship between dinosaurs and birds dates back to about 2 million to 2.5 million years ago, when both dinosaurs and birds evolved from an animal called a pterosaur.

Pterodactyls were medium-sized dinosaurs with wings, and they could fly through the air, but they were not as capable of flying as modern birds. The body structure of pterosaurs was also very different from that of modern birds, with their vertebral and limb structures more similar to dinosaurs than birds. Research suggests that the ancestor of pterosaurs may have been a prehistoric animal called the "pterosaurus", a type of lizard with wings whose wings helped them fly through the air, but they were still not as capable of flying as modern birds.

The ancestor of the pterocarpus may have been a prehistoric animal called a "lizard", which was a type of lizard with limbs that had a body structure closer to that of a dinosaur than a bird. Thus, it can be said that both dinosaurs and birds evolved from lizards, and they share the same ancestor.

Since birds and dinosaurs are two separate groups, the ancestors of these two groups are not directly connected. According to scientists, recorded dinosaurs first appeared in the Cretaceous period (about 145 to 66 million years ago), while birds first appeared in the Lower Jurassic (about 2 million to 1.45 million years ago).
