    News Agency, Nanjing, May 29 (Reporter Wang Wei ) How old is China's oldest forest? Chinese and American scholars recently published a study that gives the answer to this question: modern isotope 801 million years ago, China's forests appeared.
    Xu Honghe, a researcher at the Nanjing
    Institute of Geology and Paleontology who is in charge of the study, said the ancient forest is located in the Tacheng region of Xinjiang, China. In 2015, researchers found fossils of plant stems 70 cm in diameter in the area. Paleontical studies have shown that these plants can grow up to more than 4 meters long and are one of the oldest known trees. And these oldest trees make up the earliest known forest in China.
    , the team conducted more detailed geological surveys and isotope anthology studies of the area. High-precision isotopes on the profile of plant fossils show that this ancient forest appeared 371 million years ago. This time, more than 10 million years before the large-scale emergence of ancient forests.
    researchers also found that the forest is mainly growing stone pines, ancient sheep teeth and ferns. Ancient sheep teeth and ferns are now extinct. Stone pine plants still exist today, but the ancestry of the more ancient period has also changed significantly.
    " paleogeological study shows that more than 300 million years ago, the forest was located in a warm and humid area with tall tropical plants. And now, it's dry and desolate, and it's a different story. Xu Honghe said.
    results have been published in the international geological journal Sangu.
