Name: Giant Rhinoceros
Age: Oligocene
Location: Asia (Pakistan and China)
Size: Length 8 meters
It may seem a bit unrealistic that small, light-bodied, flat-footed animals like the running rhinoceros evolved into the largest terrestrial mammal in history, but all the evidence points to this.
The giant rhinoceros, also known as the Baloch, is named after the state of Pakistan where the main specimen was found and is large. It is estimated to weigh about 30 tons, twice as large as the largest known mammoth and almost four times that of the heaviest modern elephant. The skull alone is 1.3 meters long, but this is relatively small compared to the size of the whole body. The vertebrae and long cervical vertebrae on the back are hollow struts, similar to the largest dinosaurs, both reducing weight and maintaining strength. The legs resemble elephants, but the full weight is supported by only 3 toes, which is a common pattern in rhinos. Again, they have no horns, and in fact their nasal bones are very fragile.
The front teeth of rhino fossils vary greatly, but the teeth of giant rhinos are very strange. There are only two front teeth on each upper and lower jaws, a pair of lower fingers of the upper jaw such as fangs, and a pair of front fingers of the lower jaw. Because of the evidence that they have large, flexible upper lip, this structure is conducive to the giant rhinoceros chewing on the young leaves of the tree's top 8 meters above the ground like a giraffe.
Giant rhinos may live as small families, feeding on scattered trees on arid and vast grasslands. One of the skeletons found came from rocks formed by the mud of the swamp, and it is easy to imagine the pain of such a huge creature trapped in the swamp.
