Another type of fossilization, known as carbonization, occurs when soft tissues are preserved as thin films of carbon.
叫做碳化的另一种石化类型，发生在软组织以碳薄膜形式被保存下来的过程中。

Shortly after the Cambrian explosion, mud slides rapidly buried thousands of marine animals under conditions that favored fossilization.
寒武纪大爆发后不久，泥石流迅速将数千只海洋动物掩埋在有利于石化的条件下。

Conditions that promote fossilization of soft-bodied animals include very rapid covering by sediments that create an environment that discourages decomposition.
