Paleontology of the giant pig is not a generic "big pig", it refers specifically to a class of animals. They are pig-shaped sub-projects under the old pig head an offshoot of the early evolution, appeared in the mid-Eocene, Oligocene, when the boom time, then immediately in the extinction of the Miocene. Like the pig head in the next great Cuban body as pigs, can not be called a "giant pig". Giant pig, do the Chinese name of the past "pig." The so-called pig, is the ancient legend of a huge pig, Hou Yi shot a lot of monsters in there, "closed pig." But humans are not seen real pig, and they back in the days before Australopithecus became extinct. In a relatively short period of time, the development of the giant pig's body to the bison were so big, and therefore, "the giant pig," said. They are a great addition to the individual, the skull in mammals, accounting for the proportion of the body can be considered very large, very special structure, the zygomatic arc anterolateral, combined under the Ministry of the mandible, the horizontal branch outside of one pair of growing up under the bone protruding (the processes of modern warthog is at the moment), and in their lower jaw side, there are some strange protrusions, head elsewhere, often covered with such a "bone tumor." Limbs compared with the percentage of modern pigs and peccary have long and relatively stout, hind legs longer than forelegs. Degradation of the second toe toe side, but you can see the second toe and the fifth toe marks. Gear teeth are quite full, large canine teeth, missing teeth development. Upper and lower molars are square, each with four conical cusps. Living in the Oligocene in North America and Eurasia.
Modern warthog giant pig is our first home in Yunnan, Yunnan before the earliest members of the giant pig (eoentelodon yunnanense) on Cloud Road South unearthed late in the Eocene formation, and their animals live together, there are many kinds of early Brontotherium. Their individual small skulls and protruding mandible bone is also small. The next smaller premolars and lower molars with sharp well-developed. Therefore, the attributes of its size and ancient pigs eoentelodon the most primitive representatives. Before the giant pigs widely distributed in China, China's Ningxia and Inner Mongolia Wulanchabu Oligocene (water business group) has found that success was a class of animals. Giant Suidae entelodontidae in more well-known archaeotherium (the ancient giant pig), dinohyus (fear of pigs), entelodon (complete tooth beast) and eoentelodon (before the giant pig) and other genera. There are some categories of unknown relatives, such as the Eocene cebochoerus, some people think that it early before the giant pig, put it into "giant pig superfamily", also with a view on it and hippos, is not this type of of. Under cebochoerus (next?) Jaw teeth complete bbc animal as the star, by more attention. It is widely distributed in the fossil found in Mongolia and the U.S.. It's huge forehead than the other pigs to lower levels, indicating the amount of their brain is small compared to undergraduate relatives too poor. In addition, they are also more slender snout, two-thirds of the huge head that is the mouth of the. After the giant teeth of ancient animal skulls in the living pig Oligocene 35 million years ago, the North West. It is similar to cow size, shoulder height 5 feet, neck of the spinous process developed, is likely to have a Spanish bullfighting as "meat mound." Is probably the most famous fossil is the ancient predator that with a whirlwind, although cats hunting skills and efficiency in hunting the meat than the old teeth of animals to be good many, but soared after all, is not old and ancient giant pig a "heavyweight" players. So this shows that giant pigs are not perceived as strong animal (see blood brother spent Scissors "saber-toothed Dynasty"). So I have a suspicious animal teeth can not be completed as easily as in the bbc in the confrontation between the giant jackal animal teeth, animal teeth, especially the giant jackal may be in groups.
Fear of ancient giant pig pig size bigger than some of the rest of the physical characteristics more similar. It lived 21 million years ago in the early Miocene of Nebraska, and then some of the horse, camel type, Dafoe mammals in the grasslands of common run. They have a huge pigs final glory, big enough to have bison, prairie was the monster. Fear of pig bones, recovery plan, scale drawings, models (apparently arid steppe vegetation) giant pig may be small group activities, because of their modern relatives, including hippos, are often a small group or family life. In addition, the end teeth are often left on the animal's skull are considered similar fight scars, that they are often in contact with similar, but fortunately they made such a strong fight skull generally will not have too much risk . This is also from the side that they are unlikely to be some of the killer, because such a large guy, so if the main hunting, but will affect the efficiency of clustering. General tendency over the last giant pig is omnivorous. However, with the bbc animal counterparts, complete teeth into animal killers were described. Many recent view also take the initiative to hunt the giant pig is an animal, because there are enough to crush bone giant pig huge teeth. They believe that giant pig hunting is rushed to the basic method, and then bite. Although powerful forelimbs giant pig, but obviously not suitable for throwing himself to the hoof or catch prey. However, from the skull of view, the giant pig in the formation of a broad perspective on both sides of the body, but can not overlap the line of sight, can not form a complete vision in the forward direction clearly has a defensive rather than predatory. In addition, their huge teeth may also be stiff in order to adapt to arid regions of plant specialization occurs. So I tend to like their modern wild boar and peccary, as is plant-based complex food, of course, will not give up any opportunity to add animal protein, whether it is able to catch the weak or carrion prey. They like a bulldozer against any food he can find, looking for his huge body enough energy. Do not want to speculate the reasons for the extinction of giant pigs, and sometimes biological extinction is no "truth". Ultralisk giant pigs and are similar to adapt quickly to where the ecology of species, so very popular, but they are at their peak in the evolution of rapid decline. However, the decline of the giant pig is not because they adapt to the environment - reducing the area of grassland, prairie opposite Miocene Oligocene than even expanded. Of course, compared to other ungulates class, giant pig disadvantage is obviously much smaller brain volume, this complete monster beast teeth, brain size, and actually almost orange. In contrast, modern pigs, almost can be regarded as the most intelligent of hoofed animals. In short, this strange "terrible" animal, lived extensively in the northern hemisphere, now leave some fossils, for the experts to study, for us to comment on these paleontological enthusiasts. |
