Aliases: Velociraptor, Velociraptor

(Vignette: Tyrannosaurus has also been brilliant, and Tyrannosaurus has been classified into the Tyrannosaurus family, Tyrannosaurus superfamily, Tyrannosaurus, Tyrannosaurus, and Tyrannosaurus subfamily.) However, the reason is that because the family Tyrannosaurus and the genus Tyrannosaurus were considered " uncategorized " species " , many carnivorous dinosaurs were classified in this family , but they were not closely related to each other. ）
Fossil discovery site: First in Mongolia, and later in China, fossils of "Robberosaurus" have also been excavated.
Characteristics of the Dragon Raider
On this issue, we should analyze it step by step, and first judge from the appearance of one of the best ways to start.
It belongs to the medium-sized Chilong family, and its adult body length is generally about 2.07 meters. The height of the hips from the ground is about 50 centimeters, which is equivalent to half the height of a human leg (the height of the dragon is closer to the height of a turkey). I don't know if you have seen "Jurassic Park", the velociraptor in the movie is about 70 to 80 cm high, close to the height of the male protagonist's hip.
Paleontologists deduced from the only intact parts of the fossils that have been preserved that the adult weight of the dragon was about 15 kilograms. Among the fossils unearthed, the skull of " Shrew " was found to have a large part of its body length ( compared to other dinosaurs of the family Chi " ) , with a length of 25 centimeters. In contrast, their brains are also relatively large. Compared with other dinosaurs, the proportion of brain/body weight of Apatosaurus belongs to the largest list of dinosaurs, and the degree of brain development largely determines the degree of intelligence of the organism, so the dragon and its intelligence.
The snout of the dragon was upturned upwards, resulting in a concave surface between the nose and mouth and the eyes, and the lower jaw was raised upwards. In the mouth, there are 26 to 28 teeth with large intervals and serrated posterior margins. Somewhat similar to other dinosaurs of the family Chironidae ( Achillesurus ) , " Apatosaurus " was a bipedal , carnivorous feathered dinosaur with a stiff , upturned tail. The most fascinating thing is its extremely dangerous second toe, a dagger-like toe up to 9 centimeters long.
Features of the movie Velociraptor
Did the velociraptor in the movie leave a deep impression on you? For example, the velociraptor in the movie, unity, intelligence, bravery and so on. However, I have to say that the film has also put a lot of effort into portraying the image of the velociraptor. For example, in the movie, the velociraptor also has a long upwardly upturned toe on the hind limbs, which makes people remember the velociraptor, but is it very similar to the Spp. However, the velociraptor in the movie has no feathers, and the dragon we are talking about has a feathered dinosaur, so we can't say that they are the same dinosaur, so we have to continue to analyze this matter.
Use its front paws to find out if Apatosaurus is a Velociraptor.
Similar to other chicosaurs , it had large hands that resembled the wing bones of modern birds in structure and flexibility. The hand has three sharp and sharply curved claws, the middle claw is the longest of them, and the first claw is the shortest. The bone structure of the wrist of the dragon was very dexterous in that it could turn inward and grasp inward, rather than downward. Let's take a closer look at the velociraptor in the film work, three finger claws of similar thickness and length, not like the dragon but more like the clawed dragon, then we can conclude that the velociraptor is not a dragon.
The "velociraptor" in the film work is an artistic creation, and its phenomenon is based on the creation of the dinosaur, some of which have the upturned toes of the velociraptor, and the pterodactyl also has it. Including the height of the dinosaur (the height of the dinosaur's hip is about 0.87 meters above the ground), it is very similar to the "velociraptor" image in the movie. However, the unique skin characteristics of the "velociraptor" in the film works are borrowed from another type of spinosaur dinosaur, the heavy clawed dragon, and their common feature is that they have small spots left by feathers that have not been completely degraded.
Therefore, the "velociraptor" in most of us is just a product of people's secondary creation. But here to say, in the real world, the dragon is also called velociraptor, and what this article says is that the rexosaurus is not the same as the velociraptor presented in the movie.
An expedition from the American Museum of Natural History discovered the first fossil specimen of Apatosaurus in Mongolia's Gobi Desert in 1922; the specimen (number amanh 6515) contained a crushed but intact skull, as well as a second toe claw. Two years later, henry fairfield osborn, a scientist at the museum, named the specimen v. Mongoliensis); however, Osborne mistook the second toe claw for one from the hand. The genus name " Velox " means " fast " , raptor means " robber " or " thief " , referring to their running body structure and carnivorous diet ; and the species name is found in Mongolia.
During the Cold War after World War II, excavation teams in North America were driven away by communist Mongolia, while Soviet and Polish expeditions, in collaboration with Mongolian universities, discovered many fossil specimens of Apatosaurus, the most famous of which was the "Dinosaur in The Fight" (number gin 100/25) discovered by the Polish and Mongolian teams in 1971, which preserved the scene of a battle between a dragon and a protopodosaurus. This specimen is also considered a national treasure by Mongolia.
As the Cold War atmosphere faded, several scientific expeditions, in collaboration with China, the United States, Canada, Mongolia and other countries, have found a number of fossils of "robbers" in Mongolia and northern China. Between 1988 and 1990, a collaborative team of Chinese and Canadian scientists discovered fossils of L. ornithosaurus in northern China.
With the refinement of cloning techniques, many replicas of extinct organisms have been mentioned in bright places for discussion. Naturally, the replica work of dinosaurs will not be left behind. Folk still have great expectations for this kind of reproduction of ancient creatures, from our daily games, movies, and popular science programs we can all experience. But I am really afraid that one day such a thing will really come true, because I know that such a thing that violates nature cannot be borne by human beings themselves.
