Ediacaran

Although named after a site in Australia, the Ediacaran formation is worldwide in distribution and dates to Precambrian times.

尽管伊迪卡拉是以澳大利亚的一处地名而命名，但伊迪卡拉沉积层却遍及世界各地，并且可追溯到前寒武纪时代。

The Ediacaran fossils tell us that Darwin was being too generous.

而埃迪卡拉化石告诉我们，达尔文太“慷慨”了。

The Ediacaran fauna were the first large complex life forms to appear.

埃迪·卡拉纪动物群是出现的第一种大型的结构复杂的生命形式。

The Ediacaran fossil record thus stretches the origins of animals to well before the Cambrian Explosion.

埃迪·卡拉化石的发现，将动物的形成时间从寒武纪又推早了不少。

A key requirement for larger creatures is oxygen, and the dramatic history of oxygen levels is also etched in Ediacaran rocks.

体型更大的生物生存的关键因素是氧气，氧含量的变化史也刻在了埃迪·卡拉岩石群上。
