把该句子的倒装变正常语序应该是什么?
Missing until recently were fossils clearly intermediate,or transitional,between land mammals and cetaceans.
如何翻译呢。这个intermediate 和 transitional 指的是 fossil么？

答案

Fossiles clearly intermediate,or transitional,between land mammals and cetaceans,were missing until recently.个人觉得是intermediate 以及transitional 都是在指fossil~
