A long time ago, in xinjiang's Ulungu River Basin, the climate was warm and humid, next to a dense forest, and all kinds of birds flew freely in the sky; in the river, crocodiles sometimes appeared, and large fish surfaced; in the primeval forest, many herbivores were leisurely foraging.
The abundance and variety of food, combined with the warm climate, makes the animals live comfortably here. It used to be inhabited by many species of canine bears, such as the Ulungu bear, the Ze dog bear and the Zhe's Gobi.
However, the good times did not last long, and with the further uplift of the Qinghai-Tibet Plateau, the natural environment was harsh, forcing the dogs and bears to leave their hometowns and even perish. Curiously, they did not leave a single offspring, and the canine family disappeared. What kind of animal is this? Let's take a look.
<h1 class= "pgc-h-arrow-right" >01 canine head bear body wolftooth lion waist, combining the advantages of bears, canines and cats</h1>
Canines are an ancient family of canines, which were previously classified as canines, but in recent years, the skull structure of canine bears has been found to be extremely close to bears, so it has been separated from the canine family and classified into the canine family.
The canine bear is a "comprehensive player" of bobaijia, which seems to mix the advantages of bears, canines and cats, just like a combination of some contemporary animals: with the characteristics of a dog head, bear body, wolf teeth, and lion tail, it looks like a big bear with a big tail.
The head is as narrow and long as a dog, with an oversized head; the forelimbs of a canine bear resemble a bear, with broad feet like bear paws, and all limbs have sharp claws, but they cannot be retracted, and have a strong ability to control; the snout is prominent, sharp teeth like a wolf, especially the upper and lower canine teeth, which are strong and sharp, biting and cutting sharp tools; and the lumbar spine and hind limbs are more similar to the lions of the feline family, with a strong ability to bounce.
<h1 class="pgc-h-arrow-right" >02 is neither a bear nor a dog, as large as a polar bear and as small as a fox</h1>
A canine bear is neither a bear nor a dog, it is a canine bear, a bulky and powerful giant carnivore. Adult canine bears are 3 meters long, generally 1-2 meters tall, the highest is about 2.1 meters, and the weight is generally not more than 300 kg, and the largest may exceed 500 kg. In addition, its large tail, like that of cats, is used to control balance when running.
According to the fossils of canine bears that have been found, the individual differences in canine bears are relatively large. The smallest canine bear is also the size of a red fox, the smaller canine bear is similar to the wolf, and the medium and large dog bear, about the size of the current cheetah, is a chasing hunter, with slender limbs and good at running, and the largest is said to be as large as a polar bear.
Judging from the structure of the body, it is perfect! The inuyasha bear has a thick bear-like body and strong muscles, and its large head has a wide zygomatic arch and a towering sagittal ridge attached to a large number of bite muscles.
The teeth of canine bears are developed, especially the upper and lower canine teeth, which are very thick and sharp, and unlike the conical teeth of bears, the back edge of the canine teeth of canines has a sharp ridge, which can produce a puncture effect, but also comes with the function of cutting, and its split teeth are similar to canines, which can gnaw on the bones of prey, and is a sharp weapon for biting and cutting.
<h1 class = "pgc-h-arrow-right" >03 preyed on ancient camels and far-horned rhinos, adopted an ambush strategy, and won by surprise</h1>
Inuyasha lived in groups, was a typical carnivore, and was one of the top predators at the time, quite frightening, they were in droves, and many animals became their mouths.
The animals that are often found in their recipes are mainly prey such as three-toed horses and odd-horned deer, and they dare to eat ancient camels and far-horned rhinoceroses that are 3 times larger than themselves, and they are not soft. When prey is scarce, some plant foods are also eaten.
Canine bears may be hunted in a similar way to cats, using canine teeth to quickly kill prey. Although they can chase prey at speeds of more than 50 kilometers per hour, their endurance is still very limited, and it is not the specialty of canine bears to chase prey. Therefore, when hunting, the dog bear will generally adopt an ambush strategy and win by surprise.
<h1 class="pgc-h-arrow-right" >04 is the most afraid of pigs, and is equal to saber-toothed tigers</h1>
Although the inuyasha is a powerful character, it is not without opponents, and in the North American continent there was once a larger animal than the canine bear, the phobia pig, which is the natural enemy of the canine bear.
The pig looked emaciated, but was 3.2 meters long, about 2 meters tall at the shoulders, weighed nearly 400 kilograms, and had a large muscle group extending from the head to the back and chest, which was one of the top predators in the North American grasslands at that time.
The huge body, the unique upper and lower jaws that can be opened at right angles, and the powerful jaw muscles attached to it make the pig worthy of being the strongest pig in history. Compared with the body of the dog bear, the pig has an absolute advantage in size, and the dog bear certainly does not dare to confront it head-on.
Of course, in terms of body structure and predatory skills, canine bears and saber-toothed tigers are inseparable, they control their own territory, and they are equal to saber-toothed tigers. However, as large predators such as saber-toothed tigers increased, inuyasha began to decline.
< h1 class="pgc-h-arrow-right" > concluding remarks</h1>
From its appearance 37 million years ago to its extinction 5.3 million years ago, the canine bear once dominated Europe, Asia and Africa, and was once indispensable in the North American continent, belonging to the predators at the top of the food chain, but eventually it went to extinction.
