A piece of rice shell locks the "age" biological archeology of the ancient ship to reveal the "Yangtze River Pass No. 2"

So far, the largest wooden shipwreck found in underwater archeology, the Ancient Ship No. 2 of the Yangtze River Hits 2 on the 21st, successfully implemented the overall salvage in the waters of the Yangtze River.

At the same time, it is commissioned by the Shanghai Cultural Relics Bureau and the Shanghai Cultural Relics Protection Research Center, and a number of scientists from Shanghai well -known universities in Shanghai are also empowering the highly anticipated underwater archeological engineering with various advanced scientific and technological means.

It is understood that the scientist team of the Fudan University Science and Technology Archaeological Research Institute is conducting the rice carbon fourteen measures and ancient plant DNA research on the rice shells in the porcelain bottle in the ship.Based on this, researchers can judge the approximate age of rice shells into porcelain bottles, and verify the "age" of the ancient ship No. 2 of the Yangtze River Estuary; according to the rice shell DNA, it is roughly speculated that its origin is combined with the kiln mouth of the porcelain.The port port.This is the first time in my country that has applied molecular -level biological genetic research technology to underwater archeology.

How does the seemingly inconspicuous rice shell hide the secrets of underwater sinking ships?How will the next steps to solve more passwords of the ancient ship No. 2 of the Yangtze River Estuary?The story starts from half a year ago -at the time, the ancient ship of the Yangtze River No. 2 out of the water out of the water, including the Jingdezhen kiln green glaze cup, large blue and white ear bottle, including the bottom of the "Tongzhi Nian System".

The young team led by Associate Professor Wen Shaoqing of the Science and Technology Archaeological Research Institute of Fudan University was invited to participate in the "Biological Archaeological" project of the Ancient Ship in Changjiangkou No. 2.When they sampled the sludge in the bottom of the two -ear bottle, they found that the porcelain bottle was still "large and there was a long way" -the small porcelain cups were hidden inside, and a large amount of rice shell was cushioned inside.At the same time, the team also obtained other rice shell samples on the ancient ship No. 2 in Yangtze River.

"We carried out carbon fourteen measures on these rice shells on the ancient ship No. 2 at the fastest speed of the fastest speed. It was found that they were slightly a little earlier than the Qing Tongzhian …In the fixation and earthquake prevention of items on board. Of course, we will also test the rice shells in different places of the hull, and finally comprehensively judge. "Wen Shaoqing said that the test results of the rice shells and porcelain bottoms are confirmed to further determineThe ancient ship No. 2 of the Yangtze River was operated during the Tongzhi period of the Qing Dynasty.

The use of biological gene technology to decrypt the "age" of Yangtze River No. 2, which is just a small test for scientists.What is biological archeology?Wen Shaoqing said: "In 2022, the Nobel Nobel School of Physiology or Medicine was awarded the" Ancient genome "researchers, and biological archeology combined the ancient genome and archeology., Archeology, environmental archeology, etc. "In fact, the application of molecular archeology in the research of shipwrecks is also cutting -edge around the world.

"We tried to use different academic cross -cooperative cooperation to study the" full life cycle "of the ancient ships of the Yangtze River Estuary 2 from built to sinking, in order to achieve a new breakthrough in modern underwater archeology in my country." Said Chu Xiaobo, curator of the Shanghai Museum.

In the eyes of Wen Shaoqing, the ancient ship No. 2 of the Yangtze River is not a silent shipbuilding ship, but a huge amount of information and vibrant "life"."Actually, there are two sets of biological gene spectrum in the underwater sink -one is a" visible spectrum ‘, which includes the human bones and animals bones that may exist.The biological gene spectrum ‘is mainly microorganisms. By detecting, analyzing, and studying these biological gene spectrums, we can obtain a huge database to restore the "life body’ of the underwater sinking ship."

Wen Shaoqing said that if the bones of rodent animals such as mice can be found on the ancient ship No. 2 of the Yangtze River, or the relics of some plant seeds, then through biological genetic research, analyze where the ship might have stopped at that time.EssenceFor another example, by conducting microbial research on the sedimentation of the bottom of the ship, you can know what waters of the ancient ship of the Yangtze River Estuary 2 in the area of the Yangtze River Estuary 2, so as to "puzzle" and "restore" its entire route through its operating trajectory.

"When the ancient ships of the Yangtze River No. 2 out of the water, the public’s eyes often pay attention to whether the cultural relics on the ship are exquisite and focus on shining things, and what we need to pay attention to and discovery are the most noticed dirt depositThings. The fun of scientific research lies in receiving challenges and exploring unknown. We look forward to the smooth out of the water with the ancient ships of Yangtzekou No. 2. Through the analysis of the two sets of biological gene spectrum on the shipwreck, we can clarify where this ancient ship ‘"Come, where to go ‘. "Wen Shaoqing said.
