在2.5亿年前,地球上曾发生过一次神秘的灾难,导致地球上95%以上的物种灭绝。与这次神秘事件相伴的是,中国西南浅海地区普遍形成了一层厚达数米的树枝状、网状和斑点状岩石——地球上有化石记录的最早古赤潮。自20世纪80年代以来,我国云南滇池每年4~11月都会暴发水华。严重时,藻体在湖面形成厚达数厘米的藻浆,犹如覆盖了一层厚厚的油漆,当地居民俗称其为“海油”。造成滇池水
Over 250 million years ago, a mysterious catastrophe occurred on Earth, resulting in the extinction of more than 95% of the earth’s species. Accompanying this mysterious incident was the widespread formation of dendritic, reticular and speckled rocks a few meters thick in shallow sea areas in southwest China - the earliest ancient red tide recorded on Earth by fossils.
