Sichuan elephant medical equipment maintenance

Sanxingdui is a civilization discovered in Sichuan, which is not recorded in ancient books. It is the representative of ancient Shu civilization. There are bronze sacred trees, great figures and bronze masks in it, and a large number of ivory were found when Sanxingdui was excavated.

In today's China, elephants are only distributed in the tropical rain forest around Xishuangbanna, Yunnan, and there are no elephants in Sichuan. So where did Sanxingdui's massive ivory come from?

Through the examination of modern science and technology, it can be confirmed that the ivory found in Sanxingdui belongs to the ivory of Asian elephants, and it can be confirmed that the ivory is produced locally, which actually answers this question. Not long ago, there were elephants in Sichuan thousands of years ago when Sanxingdui was located.

Now people's judgments on China's geographical environment and natural life are based on the current situation, but in fact, this situation is very different from that of thousands of years ago, whether it is climate or biology. For example, people now think that there are no rhinos in China, but in fact, rhinos in China were extinct from the late Qing Dynasty to the end of the Republic of China.

In fact, elephants are also like this. Thousands of years ago, the Yellow River valley was densely forested and the climate was warm and humid. Elephants are widely distributed in the Yellow River basin. We know that the traitor in Henan is Yu, which means a person holding an elephant from the glyph, and it is also recorded in the bronze inscriptions of the Zhou Dynasty. In other words, there were still elephants in this area of Henan in the Zhou Dynasty. In places like Chang 'an, in the Tang Dynasty, there were rhinos.

Sanxingdui was probably in the Xia and Shang Dynasties, earlier than the Zhou Dynasty, and the geographical position of Sichuan was farther south than that of Henan in the Yellow River basin, and the climate at that time was warmer and wetter, so it was not surprising that elephants were distributed. In fact, this can be confirmed by the discovery of many other historical sites.

So Sanxingdui's ivory comes from around Sichuan where there are elephants. Only now, with the change of climate and environment and the killing of human beings, many animals that existed in ancient times have disappeared from their original habitats.
