在中国北部乌达煤矿附近发现了有着2.98亿年历史的石化森林。就像罗马古城庞贝一样这片10763平方英尺（1000平方米）的木质泥炭被古老的火山喷发出的火山灰保护起来了。
在《国家科学研究院论文集》中记载了这项令人瞩目的发现，当年火山喷发时“记录”下了当时的气候和生态环境。这是宾夕法尼亚大学古植物学家Hermann Pfefferkorn和中国科学院王军、沈阳师范大学张翼和云南大学卓峰共同的研究结果。
Pfefferkorn在宾夕法尼亚大学出版的关于森林的书面声明中说道，“这些都被很好地保存了下来。我们站在那里能看到一堆叶子的树枝，之后你还会发现更多的树枝，还有这棵树的树桩！这多让人兴奋啊！”
缅因州我特维尔科尔比学院的古植物学家Robert Gastaldo也很兴奋。
“这简直是一个研究奇迹，”Gastaldo告诉《自然》杂志，“这些植物群里面的很多种我们都是从其他地方了解到的，但是我们之前并不知道他们事实上都生长在一起。”
画家的作品展示3亿年前在中国内蒙古埋藏在火山灰下的热带森林。
A fossilized, 298-million-year-old forest has been found under a coal mine near Wuda, in northern China. Like the Roman city of Pompeii, the 10,763-square-foot (1,000-square-meter) peat forest was preserved by ash spewed out by the eruption of an ancient volcano.
The remarkable find--to be described in Proceedings of the National Academy of Sciences--gives a "snapshot" of the climate and ecology at the time of the eruption. It was the result of a collaboration between University of Pennsylvania paleobotanist Hermann Pfefferkorn and Jun Wang of the Chinese Academy of Sciences, Yi Zhang of Shenyang Normal University and Zhuo Feng of Yunnan University.
"It's marvelously preserved," Pfefferkorn said of the forest in a written statement released by Penn. "We can stand there and find a branch with the leaves attached, and then we find the next branch and the next branch and the next branch. And then we find the stump from the same tree. That's really exciting."
Those sentiments were echoed by Robert Gastaldo, a paleobiologist at Colby College in Waterville, Maine.
“This is a wonderful study,” Gastaldo told Nature. “Many of these plant groups we knew from other places, but we had no idea that they actually grew together.”
