Recently, archaeologists discovered a 15-million-year-old Ziziphus jujube fossil, so some people are curious about how this South Ziziphus jujube was preserved? The preservation method of Ziziphus jujube is somewhat similar to the formation of mummies. The form of Ziziphus jujube is preserved through drying and dehydration. 1. The appearance of Ziziphus jujube

The fossil of Ziziphus jujube was discovered by an American archaeological team in Zhangpu, Fujian. This Ziziphus jujuba lives in tropical and subtropical arbor forests, and according to historical data, it was discovered in 8000 Ancient people 20 years ago had already eaten South Jujube and stored it in large quantities. This time the archaeological team discovered seven Ziziphus jujube fossils in one go. Their shapes are basically the same as our modern Ziziphus jujube. The only difference is that there are 3-6 holes on the top of modern Ziziphus jujube, while the fossil Ziziphus jujuba has 7 holes on the top. That is to say, the ancient Chinese jujube forms were more diverse. According to archaeological data, Ziziphus jujube was once widely distributed in Eurasia in ancient times, but now it only exists in South my country. 2. The functions of Ziziphus jujube

Compared with other jujubes, Ziziphus jujube is harder and has a larger core. Because there are five holes on the top of the South Jujube, it is also given the meaning of five blessings. Jujube pulp contains nutrients such as cellulose, organic acids and proteins, which are very effective in treating cardiovascular disease, diabetes and enhancing immunity. The trunk of Ziziphus jujube is straight and the bark is grey-brown. The flowers blooming on the tree are lavender, and the flowering period usually lasts about four months. When mature, the drupe is oval in shape, yellow in color, and pulpy in texture. Ziziphus jujube is generally distributed in Zhejiang, Fujian and Yunnan and other regions in my country. Not only can it be used for medicinal purposes, Ziziphus jujube fruit trees can also stop bleeding, relieve pain and treat large-area burns. 3. Continuing to the present

Twenty million years ago, Ziziphus jujube was widely distributed in Eurasia. However, according to current research, Ziziphus jujube has become a plant unique to East Asia. That is to say, South Jujube has existed since ancient times and is distributed in South my country.
