我知道选D，我是用的排除法，但是D的那个MAKING做伴随状语表目的，还是什么意思，直白点说，我一直没明白什么时候用VING形式，请好心人帮忙解答，谢谢

Ving是个万金油~你就把它看做随意指代就行~比如前面说了一事 Ving就可以指代这事~  它不像 it that which who 需要就近 跳跃 判断逻辑主语。。
在这个题里就是化石被发现这事是那动物成了最早的什么什么。。

白勇语法全解这么讲到：
“Ving分词短语在句尾：
1.表伴随动作、状态、功能，与句子谓语动作同时发生，逻辑主语等于句子主语。
2.表伴随结果，整个句子是原因，导致分词动作产生，无逻辑主语。可以在分词前加thus，thereby, in effect等，也可以不加。”
个人觉得这题，making...后面一大串是作伴随结果的，也就是说当树懒的手臂化石被发现后便使得它成为i这个地区最被人们所知的哺乳动物。
希望对你有帮助。
