1. (使)成為化石;石化 If the remains of an animal or plant fossilize or are fossilized, they become hard and form fossils, instead of decaying completely.
e.g. The most important parts, the flowers, rarely fossilise... 最重要的部分，即花朵，很少成為化石。 e.g. The survival of the proteins depends on the way in which bones are fossilised. 蛋白質(zhì)是否存留取決于骨頭被石化的方式。
2. (使)僵化;(使)陳舊 If you say that ideas, attitudes, or ways of behaving have fossilized or have been fossilized, you are criticizing the fact that they are fixed and unlikely to change, in spite of changing situations or circumstances.
e.g. What they seem to want to do in fact is fossilize the particular environment in which people live and work... 他們似乎想要做的實(shí)際上就是讓人們生活和工作的環(huán)境固定不變。 e.g. Needs change while policies fossilize. 需要發(fā)生改變，但是政策僵化不變。
