Dinosaurs belonged to the family Chiosauridae, which was 150 million years old. In the 1960s, there was a lot of research on dinosaurs, and there was a big break. In the past, many people thought that the red-clawed dragon was small and slow to perform, but after delving, it was found that this dinosaur was petite and a bit like an ostrich.
1. The body characteristics of the dinosaur.
The length of the dinosaur was up to 3At 4 meters, the shape of the claws is extraordinary, and it is very powerful. Many people think that dinosaurs often use their claws to cut their prey, but in fact, through the reconstruction of the model, it has been proved that the important role of claws is piercing.
Dinosaurs had sheaths with large toe claws that could reach up to 12 cm in length. The tail structure of the dinosaur is also extraordinary, and it is very stiff, and the important role is to maintain balance, and also have the ability to turn. A fossil specimen found in Mongolia that the tail of the red-clawed dragon was straight backwards.
From this analysis, the dinosaur was very sensitive and powerful. When running, because the claws are relatively large, the grip is relatively good, and the speed will be very fast. The bones of the head are also extraordinary, capable of reaching 41 cm. The height of the dispersion can reach 0287 meters and a weight capable of reaching 73 kg.
The upper jaw of the dinosaur was arched, the oral cavity and nasal cavity were narrow, and the cheekbones were broad. Judging from the whole time, the head is very flat, and there is a certain sense of resignation. The eye sockets of the Confucius dragon itself are relatively large, and the eyes are scattered on both sides of the head. It can be seen that the scope of vision is very broad.
2. The survival habits of dinosaurs.
Dinosaurs had large claws, so they sometimes preferred to live on tree trunks, but most importantly, they preferred to survive in tree cavities. They often live in seclusion with their partners, but when they encounter their prey, they will go out together so that the prey is caught. In terms of hatching, dinosaur eggs were laid as they were the same as the rest of the dinosaurs.
Dinosaur scientific name: deinonychus) is a genus of dinosaurs in the family Gallosauridae, with a body length of about 34 meters, lived in the middle of the Lower Cretaceous Apdi to the early Albu Order, about 115 million to 108 million years ago.
Its scientific name comes from the ancient Greek words "δ meaning "terror") and "claw"), because it has very large, sickle-shaped toe claws on the second toe of its hind limbs, which may be retracted when walking.
3. Walk on the fourth toe.
Dinosaurs were thought to have used their sickle claws to cut their prey, but recent tests of reconstructed models of velociraptors have shown that the claws were used for stabbing rather than cutting.

Its skull has a strong jaw with about 60 curved, knife-edged teeth.
Ostrum originally reconstructed the incomplete skull of a dinosaur into a triangular, broad head that resembled an Allosaurus.
The discovery of more and more complete fossils of dinosaurs and their close relatives showed that the dinosaurs had a more arched palate, a narrower muzzle, and broad cheekbones, giving the head a more three-dimensional appearance, unlike the Ostrum reconstruction.
The skull of a dinosaur was different from that of a velociraptor in that the top of its head was stronger, similar to that of a galloping dragon; The upper side of the nose of the velociraptor was concave downward, unlike the dinosaur.
There were holes in the skull and jaw to reduce the weight of the head, and the preorbital foramen of dinosaurs was particularly large.
Extrapolating from the skull, the eyes are mainly oriented to the sides.
Like other gallosauridae, dinosaurs had large palms and three fingers.
The first finger is the shortest, while the second finger is the longest.
The second toe of each hind limb has sickle-shaped toe claws, about 13 cm in length, and may have been used as a predatory animal.
It can stab forward first and cut down to tear through its prey.
Relative to the size of the dinosaurs, these claws were quite large.
The body of the clawed dinosaur relied on the tail vertebrae and herringbone to maintain stability and balance when turning at high speeds.

The first fossil of a clawed dinosaur was discovered in 1931 by a team led by Barnum Brown in the Cloverly Formation in southern Montana.
Brown was primarily interested in excavating and disposing of the remains of tenosaurus, but in his 1931 report to the American Museum of Natural History, he noted the discovery of a small carnivorous dinosaur that was close to a tenosaurus fossil but difficult to clean because it was trapped in limestone.
He informally named it daptosaurus, and was ready to describe and display its skeleton, but he did not complete it.
In addition, Brown confused the teeth of a dinosaur with the skeleton of another smaller theropod dinosaur and informally named it Megadontosaurus.
About 30 years later, beginning in August 1964, paleontologist John Ostrom led an excavation team from the Peabody Museum of Natural History at Yale University, which found more than 1,000 bones from at least three individuals over the next two years.
Because it is difficult to determine the correct location of these fossils, the holotype specimen of the dinosaur (YPM 5205) is limited to the intact left foot, and part of the right foot, but both are determined to belong to the same entity.
Other specimens are identified and labeled into 50 different items at the Peabody Museum of Natural History at Yale University.
In the years that followed, Ostromum and Grant E. MeyerMeyer) studied the newly discovered fossils, as well as the daptosaurus fossil named after Brown, found that they were homogeneous, and published their findings in 1969 under the title Deinonychus antirrhopus.
The species name antirrhopus means "balanced" and refers to the possible use of their strong tails.
Scaling Ostrom also re-examined the megadontosauru that Brown had named, and found that the tooth belonged to a dinosaur, while the skeleton was from another animal.
In 1970, he named the skeletal part of the little hunting dragon.
Although a large number of dinosaur fossils were discovered in 1969, many important bones were not found, and the rest is difficult to identify.
The fossils contain a handful of postorbital skulls, no femur, no sponsor bone, no wishbone or sternum, no vertebrae, and a small fragment believed by Ostrum to be a bird's beak bone.
Ostrum reconstructed the dinosaur into a dinosaur with a unique pelvis with a trapezoidal and flat pubic bone that was the same length as the ischial bones.
Dinosaurus is a very lethal small and medium-sized dinosaur that lived during the Cretaceous period and is considered the most unusual predator. On the palmar toes of its left and right hind limbs, there is a sharp claw known as the claw of terror. These two claws are about 12 centimeters long and resemble a sickle. When hunting prey, it lands on the ground with one foot and raises sickle-like claws with the other, and with the cooperation of the sharp claws of its forelimbs, it is easy to disembowel the prey and put it to death at once. The dinosaurs were a very large and diverse group of theropods, and they were also the most evolved of theropods.
They emerged from the mid-Jurassic period and evolved into widespread throughout the Cretaceous period, and were smaller, more agile, with longer forelimbs and longer, more pointed jaws than the large, bulky carnivorous dinosaurs. They are fast runners and are able to prey on insects and small mammals.

3. Walk on the fourth toe. Dinosaurs were thought to have used their sickle claws to cut their prey, but recent tests of reconstructed models of velociraptors have shown that the claws were used for stabbing rather than cutting.
Dinosaurs could be up to 3 years long4 meters, the length of the skull can reach 41 cm, and the height of the hips is 087 meters and a weight of up to 25 kg.
The cranial jaw of the dinosaur was strong, with about 60 curved, blade-shaped teeth.
Ostrum originally reconstructed the incomplete skull of a dinosaur into a triangular, broad head that resembled an Allosaurus.
The discovery of more and more complete fossils of dinosaurs and their close relatives showed that the dinosaurs had a more arched palate, a narrower muzzle, and broad cheekbones, giving the head a more three-dimensional appearance, unlike the Ostrum reconstruction.

The skull and jaw had holes to reduce the weight of the head, while dinosaurs had very large preorbital foramina.
When turning at high speeds, the body of the dinosaur relies on the tail vertebrae and herringbone to maintain stability and balance.
Claws are one of the main predators of carnivorous dinosaurs**, and it is generally believed that the largest and most ferocious dinosaurs must have the fastest and sharpest claws.
This is not the case.
Some small and medium-sized carnivorous dinosaurs compete to develop their own "unique **" in the cruel competition for survival
So who is the dinosaur with the sharpest claws? It's a dinosaur.
Dinosaurs were theropod dinosaurs that lived during the Cretaceous period. Its fossilized bones were found in North America. Dinosaurus was about 3 meters long, and was distinguished by a large scimitar-like claw on the second toe of each of its feet.
In 1969, Ostrom in the United States conducted an in-depth study of dinosaur claws. He found that the dinosaur had long, powerful limbs and light bones, which showed that the dinosaur was good at running, and its tail vertebrae had many bony clubs, which kept the tail strong, so that it could control the direction so well that it could catch its prey while running. But its biggest feature is that it has a pair of specially structured feet. It walks on its hind limbs, has four toes on its feet, each toe has sharp claws up to 15 centimeters, the second toe is particularly large, like a long and curved hook, three fingers on each of the forelimbs, and the fingers also have sharp claws, the claws correspond to each other, can grasp food, when the dinosaur encounters its prey, first use its hind paws to pounce forward, so that it is deeply rooted in the body of the prey, and then, with the front paws to tear the prey apart. Dinosaurs took advantage of this ** to make themselves one of the most ferocious groups in the dinosaur family.
In 1964, paleontologists discovered a monster in Montana, USA, and he was kept in the dust for more than 100 million years. This monster is the dinosaur claw, which means "claw of terror". It is considered the most unusual predator. The very sharp claws indicate that it is a carnivorous dinosaur.
The body shape of a dinosaur.
Dinosaurus is a small and medium-sized dinosaur with a variety of sharp weapons attached to its body, which is extremely lethal, with a large head, powerful upper and lower jaws, and teeth like sharp teeth. The forelimbs are slender, with three fingers with long pointed claws, and these claws are very flexible and easy to grasp, the hind limbs have four toes on the palms, and it often lands on the ground with the long third and fourth toes to support the weight of the body, and the claws on the second toe are called "claws of terror", in addition to these, the dinosaur also had a pair of large eyes and a strong, stiff tail.
The giant claws of a dinosaur.
The "terrifying claws" of the dinosaur grow on the second toe on the palm of its hind limbs, about 12 centimeters long, like a scythe, and the dinosaur uses it as a predatory tool, its claws connect ligaments, which can adjust the angle, so that when it attacks, it can poke its toes downward or forward in the largest arc towards the prey, while the dinosaur will retract the second toe during walking or running, so as to avoid the claws being dulled by constantly rubbing the ground.
A close relative of a dinosaur.
In 2001, scientists from the United States and China collaborated to prove that this dinosaur was closely related to birds, and it may have been covered with feathers like birds. Moisturizing and protecting against heat, the head and forelimbs also grew long, brightly colored feathers, and the Swiftlodsaurus was as ferocious as a dinosaur, as can be seen from a fossil of the Raptorus excavated in Mongolia, its long forelimbs were inserted into the head of the enemy, and one of the sickle-like claws remained in the body of the protoceratosaurus.
Dinosaur lifestyle.
Compared to giant carnivorous dinosaurs such as Allosaurus, dinosaurs were relatively lightweight. Together, they will hunt and tear animals apart with their "claws of terror", and then share the food together.
The ability of the dinosaur.
Dinosaurs had their own predatory skills; It jumps up to attack its prey, grabbing it with its forelimbs, one of its feet landing on the ground to balance its body, and the other kicking at the prey with its sickle-like claws, leaving a bloody wound on the prey and eating its internal organs, while its tail balances the strenuous activity of its body by rocking from side to side as it pounces on its prey.
Dinosaur business card. Name: Dinosaurus, Period: Early Cretaceous, Appearance: 3 meters long, 60 kg in weight, Order: Theropods, Distribution: North America: United States.
It should be to make Buddha Dragon....I once went to Grant E. Montana, USAMeyer and John HOstrum first discovered dinosaur fossils.
The large head of the dinosaur had very sharp teeth and a strong jaw.
It stands on two feet and has relatively short forearms.
Each hand has three fingers with long, pointed claws, and each foot has four toes, one of which has a 5-inch (about 12 cm) long claw.
It has a long tail.
Its eyes are very large, so it can see very clearly.
Dinosaurs were very intelligent, they hunted in packs and ran very quickly.
Dinosaurs were carnivores.
It eats any animal it can hunt and tear apart.
b] Dinosaurs also had a unique set of hunting skills: one foot on the ground, the other foot raised sickle-like claws, coupled with the cooperation of the claws of the forelimbs, it is easy to disembowel the prey and put it to death at once.
is the most unusual predator.
For dinosaurs, its front finger was also unusually long, but for dinosaurs, it was just long enough to grab its prey and then kick the prey in the stomach with its hooked feet and tear it apart.
I'm sure it's the fastest dragon. But not a good long-distance runner....It resembles a gallimimus or troodon.
The speed of these two dinosaurs was between 56 and 80 kilometers per hour.
Be agile. Equivalent to the speed of a racehorse running.
The ability to run fast gives this type of dinosaur an advantage over other animals: first, to hunt down prey; The first is to evade enemy attacks.
So the fast-moving herbivorous dinosaurs and carnivorous dinosaurs began a race for speed: in order to escape the carnivorous dinosaurs, which were running faster and faster, the herbivorous dinosaurs had to run faster and faster. Sfron was discovered by me in Sichuan, and their pelvic bones are round and large, like the current rotor motor. Further investigation is needed.
