Earliest evidence of wildfire discovered 科学家在英威尔士发现最早野火证据

考古学家在英国威尔士发现了有记录以来最早的野火证据。这个证据以烧焦残余物的形式存在于极为古老的泥岩中。

Go back to what's known as the Silurian Period and Earth looked very different from today. What is now the UK, would've been south of the Equator. A few pioneering plants had begun to evolve, but nothing containing wood; no trees, no shrubs.

回到志留纪,那时的地球看起来与如今大不相同。现在的英国当时应位于赤道以南。一些先锋植物已经开始进化,但没有一种植物含有木头,也没有树木和灌木。

However, according to this new evidence, pulled up in mudstones from under Rumney (in Wales), there was still plenty of fuel, which could have started a wildfire, in the form of giant mushrooms, called Prototaxites. All that remains of these strange organisms now, is fragments of charcoal.

然而,据这个从威尔士拉姆尼地底泥岩中钻取出的新证据显示,那个时期仍有大量燃料可能会引发野火,作燃料的是一种被称作原杉藻的巨型蘑菇。现在,这些奇怪的生物体只剩下了炭碎片了。

Ian Glasspool, a palaeobotanist from Colby College in the US, says the 430-million-year-old Welsh charcoal, pushes back the earliest known evidence of a wildfire by 10 million years.

美国科尔比学院的古植物学家伊恩·格拉斯普尔说,这些在威尔士发现的距今4.3亿年的炭碎片将已知最早的野火证据提早了1000万年。
