Why is the proof that dinosaurs have feathers still not known to the general public?

From "100,000 Whys", we know that some dinosaurs had feathers, and birds may have evolved from dinosaurs. In fact, feathers are difficult to preserve in fossils, but there are several valuable dinosaur fossils with traces of feathers found in China, so there is considerable emphasis on the promotion of feathered dinosaurs in the field of paleontology-related education in China. The most famous is probably this fossil, the Chinese dragon bird, which used to be seen in various popular science magazines.

Also, Archaeopteryx are dinosaurs, and everyone knows that they are fluffy (Archaeopteryx, say goodbye to the ancestors of birds). If the subject carefully watched the CCTV documentary, or more dinosaur-related documentaries (I was most impressed by the BBC's "Walking with Dinosaurs", which shocked me at the time that it could be filmed like this), you should notice that most of the dinosaurs were bare, or ** covered with scales. Feathered dinosaurs seem to have appeared in the late Jurassic period, and they are all small carnivorous dinosaurs, not domineering enough to be on the ...... movieAs for the pterodactyl that appeared in the movie and dominated the sky, in fact, no one was a dinosaur.

According to Jurassic Park** and Jurassic World, the park was originally built to produce the monsters of modern imagination, not to restore real dinosaurs. If we use this understanding, we can even come up with a picture: looking at a flock of big fluffy turkeys in a velociraptor field, the sponsor says don't fool me with turkeys, we need to see live dinosaurs with scales.

By the way, there is a domestic science fiction ** that talks about this, Wang Yanzhong's "Velociraptor Resurrection Plan". In fact, most of the teachers in my college are studying the Liaoxi biota of Northeast Asia, and the most famous of the Liaoxi biota is the feathered dinosaurs, among which the microraptors, nearornithosaurs are generally large and pigeons, and the larger ones such as the Chinese raptors and tail-feathered dragons are not too good because they have beaks, and their feeding habits are also phytophagous. <>

Generally speaking, most of the species of the evolutionary branch of the hypophysiosaurus can be set with feathers, and the recent discovery of the cunca hunting dragon of the carnivorous genus of the lower order of the saurodontosaurus, and the more primitive squirrel dragon of the superfamily Spotted dragon have found feather traces. But the primitive feathers are mainly used for heat preservation, so most of the dinosaurs with primitive feathers are not giant breeds, so the setting that Tyrannosaurus rex has no hair is understandable, but dinosaurs without feathers are really not good-looking, like white-striped chickens. In order to match the settings of the previous films, the producers added the settings made for commercial purposes.

A friend of mine said, you like to study dinosaurs and like to be furry, but we just want to see what looks like lizard monsters, and I think the producers may also take care of the majority of the audience to do this, so it's a good thing to leave a little bit of freedom for the movie, even if it's not really true in the strict sense. <>

It has been recognized in the academic community for many years that the small hypophyllosaurs and galloping dragons were covered in feathers and flight feathers, and that they were closely related to the ancestors of birds, and this is a well-established common-sense fact. - Our group are all professionals who have studied dinosaurs for many years, and we have no choice but to insist on the truth when it comes to this kind of basic principle. He tapped on the table.

The employees of the investment company shook their heads, and the person in charge of the marketing department was extremely dissatisfied with Tao Qinzhi's professional tone: "I think you made a mistake - a very simple thing, the contract is written in black and white - what we want you to copy is a dinosaur!" The company wants to show the tourists dinosaurs, not pheasants!

Dinosaur Eco Paradise is not a chicken farm! The colleagues next to him hurriedly let out a well-timed laugh. Tao Qinzhi knows that there is a limit to his patience with ignorance.

He grinned and said, "Then I would like to ask, what kind of 'dinosaur' your company wants is a magical thing?" "I searched the nearby Carnegie Museum of Nature and Art, and indeed there is a place for feathered dinosaurs in the exhibition hall, which shows that foreigners are also engaged in publicity.

Dinosaurs with feathers include Beipiosaurus, Millennium Ornithosaurus, Microraptor, Crested Dragon, Foot Feather Dragon, etc.

1. Beipianosaurus: It is one of the first feathered dinosaur species excavated, which may be the ancestor of modern birds.

2. Millennium Chinese Ornithosaurus: It is the fifth feathered dinosaur found, its body length is about 1 meter long, it lived hundreds of millions of years ago, and mainly fed on small birds.

3. Gu's Microraptor: With long feathers on its legs and forelimbs, it was the first four-winged dinosaur ever discovered. Born 100 million years ago, it is the smallest of the dinosaur family, with a body length of only 42-83 cm and a weight of only 1 kg.

4. Crested Dragon: Crested dragon existed 10 million years earlier than Archaeopteryx, Archaeopteryx was the first bird species ever discovered, and its discovery confirmed that dinosaurs had feathers before birds.

5. Foot Feather Dragon: Its hind wings are very similar to Gu's Microraptor, its feathers are very bent and not suitable for flight.

Dinosaurs, refers to the most recent common ancestor of Triceratops, modern birds, and Diplodocus and all their descendants. To facilitate research, dinosaurs can be divided into avian and non-avian dinosaurs. Among them, non-avian dinosaurs lived only in the Mesozoic era (Triassic, Jurassic and Cretaceous) and were all extinct 65 million years ago.

This entry mainly introduces non-avian dinosaurs.

The muscular limbs, long tails, and massive bodies are some of the non-avian dinosaurs. They mainly inhabit woodlands or open areas on lakeshore plains (or coastal plains).

The fossil remains of a small dinosaur named Yaolong, which showed long, banded tail feathers.

Scientists are able to know that dinosaur fossils had feathers because some of the fossils have preserved feather-like tissue structures and fibrous structures, among other features. Due to the changes in the internal and external structure of the organism during the petrification process, most of the soft tissues and first weaves are difficult to preserve, but some feather outlines, the texture of pure feathers, and some cells and protein molecules are tightly attached to the rock. By analyzing, observing, and extrapolating these traces, scientists can conclude that dinosaur fossils had feathers.

In addition, scientists have also established branching lines of bird evolution by analyzing morphological, genetic, and behavioral characteristics of modern birds, and classified some dinosaurs as birds, which means that dinosaurs may have had a similar feather structure to modern birds. At the same time, long feather morphology has been found on the tail of some dinosaur fossils, which also provides direct evidence that dinosaurs had feathers. This evidence suggests that dinosaurs may not have been just reptiles, but also had some ability to fly in shelters, and that their feathers may have played a role in gliding through the air, similar to animals such as today's flying squirrels.

The split-only dinosaurs with feathers are: Beipiaosaurus, Millennium Chinese Ornithosaurus, Gu's Microraptor, Meilong, and Footfeather.

1. Beipianosaurus: Beipianosaurus is one of the first feathered dinosaur species excavated in 1997, and the excavation site is located in Beipiao City, Liaoning Province, China. The body of the dragon is covered by down-like feathers, like the Chinese dragon bird, but the feathers of the dragon are longer and perpendicular to the arms.

The down feathers of the Beipianosaurus, Zhaozhou, represent that they are an intermediate species between the Chinese dragon bird and the higher birds.

2. Millennial Chinese Ornithosaurus: The Millennium Chinese Ornithosaurus was discovered in 1999 during archaeological excavations, and it is the fifth feathered dinosaur found, and several other feathered dinosaurs have also been excavated from China. Structural anatomical studies have revealed that the dinosaurs had jaws containing grooved fangs, suggesting that they may have been the first known venomous dinosaur.

3. Microraptor: The first study on the description of Microraptor Gu's was published in 2003, and this discovery will play a key role in paleontologists' understanding of the evolutionary transition from dinosaurs to birds. They have long feathers on their legs and forelimbs, and they are the first four-winged dinosaur ever discovered.

4. Meilong: Meilong is also known as the "beautiful sleeping dragon", in 2003 in Liaoning excavation site found that this bird-like dinosaur has a unique behavior, excavated a well-preserved goose-like size fossil presents a "wonderful sleeping posture", it will nest its head under one side of the forelimbs, just like modern birds hide their heads under the wings to rest and source shelter.

5. Foot Feather Dragon: The hind wings of the Foot Feather Dragon are very similar to Gu's Microraptor, and its feathers are very little curved, which is not suitable for flight. Their longer feathers can only serve as a show off and attract the opposite sex.
