解释A中说：Because "sloth" is the object of a preposition and not the subject of the sentence, there is no reasonable antecedent for the pronoun "it"; in this construction, the subject of made is fossils, but it makes no sense to say that the fossils made it the earliest known mammal.

难道是因为"sloth"是宾语，就不能被"it"指代吗？这句话made it读起来确实有问题，但答案的解释也想不通哦

是修饰fossils，提取主干， fossils (of ....)( found...) and (dated...), made it ..... 就很清楚了吧。。。

是这样的，在A OF B的结构中，指代是指代A的或者指代关键字的，这里的it就没有了指代，
