“Geodating of The Month: Rice Fossil”


Rice is one of the most widely consumed staple food in the world especially in Asia. Rice production is an important part for the development of Chinese civilization.
Some researchers studied the rice fossil (mainly from phytoliths) found at the Shangshan site in the Lower Yangtze, and they compared carbon dating of the phytoliths and other materials from the same environment to determine the ages of fossils based on the decay of Carbon-14 in the fossils. As carbon-14 decays with a half-life of about 5,730 years, its radioactic decay limits age determination to the order of 50,000 years.
The research, published in the Proceedings of the National Academy of Science, suggests that rice was domesticated in China at about 10,000 years ago.
