Xinhua News Agency, Beijing, January 4? An international team recently reported on the online edition of the American Journal of Contemporary Biology that they had discovered fossilised remains of the ancient forest in southeastern New York, about 100 million years ago, the oldest forest in the world to date.
A team of researchers from institutions such as the State University of New York at Binghamton and the University of Cardiff in the UK said they found the ancient forest remains in the mid-pelvic strata in southeastern New York about 100 million years ago. A forest remains 40km from here were previously considered \"the oldest\" by scientists, while the newly discovered remains were three to two million years earlier.
This ancient forest was a subtropical or temperate wetland 100 million years ago. The researchers believe that at the time there were two main plants that took root. One is the genus Old Goat, whose stout roots extend radially, with a radiation range of about 11 meters in diameter. Ancestral plants are considered ancestors of conifers such as pine and fir. New discoveries show that long and tall trees emerge earlier than scientists thought.
The other is a similar-shaped fern to coconut trees,1 to 2-year-old, with an entire root radiating radius of about 1 to 2 meters, of which the main root is only 20 to 50 centimeters in diameter. The ferns were also found in the remains of the ancient forest 40 km away.
Large-scale forests of the Carboniferous began to increase after mass extinctions on Earth at the end of the Devonian, about 100 million years ago, and the massive trees that piled up in the strata became coal under the action of geothermal and pressure.
