The United States has discovered the remains of the world's oldest forest

BEIJING, Jan. 4 (Xinhua) -- An international team recently reported in the online edition of the American journal Current Biology that they have found fossil remains of ancient forests about 386 million years old in southeastern New York, the remains of the world's oldest forest ever discovered.
A team of researchers from the State University of New York at Binghamton and cardiff University in the United Kingdom said they found the remains of the ancient forest in the mid-Paleo-Basin formation in southeastern New York, about 386 million years ago. A forest remains 40km from the site were previously considered the "oldest" by scientists, and the newly discovered remains are between 3m and 2m years old.
the ancient forest was a subtropical or temperable wetland 386 million years ago. The researchers believe that there were two main plants that had rooted here at the time. One is an ancient sheep-toothed plant with a radiant extension of its stout roots, with a radiation range of about 11 meters in diameter. Ancient sheep-toothed plants are thought to be the ancestors of conifer trees such as pines and fir. New findings suggest that long-lived and tall trees appear earlier than scientists previously thought.
is a fern similar in shape to a coconut tree, born 1 to 2 years old, with a radiation radius of about 1 to 2 meters for the entire root system, of which the main root diameter is only 20 to 50 cm. The ferns have also been found in the remains of the ancient forest 40 km away.
At the end of the mud basin period, some 360 million years ago, there was a mass extinction on Earth, and since then large-scale forests of the Charcoal Age have begun to increase, with large numbers of trees piled up in the formations turning into coal under geothermal and pressure.
