E.  sloth which, found in Puerto Rico in 1991, was dated at 34 million years old, made the sloth the earliest known mammal of

答案是D，

(1)为什么不是E？

(2) D为什么要用have been...?

(3) found 和 made 属于什么成分，是谓语还是定语？如何区分是“谓语动词”还是“作修饰的过去分词”？

１）Ｅ的明显错误在于并列的谓语ｗａｓ　ｄａｔｅｄ和ｍａｄｅ之间没有ａｎｄ连接。

２）ｈａｖｅ　ｂｅｅｎ　是因为ｉｎ　１９９１，这里暗含的时态ｃｌｕｅ是　ｓｉｎｃｅ　１９９１，自１９９１化石被发现以来．．．

３）Ａ逻辑错，是化石的年代确认这一事实证明了树懒是最早的哺乳动物，而不是化石使得树懒成为最早。在这里ｆｏｕｎｄ和ｄａｔｅｄ分词作定语，ｍａｄｅ是谓语动词，后有宾语及宾语补足语。

楼上说的  １）Ｅ的明显错误在于并列的谓语ｗａｓ　ｄａｔｅｄ和ｍａｄｅ之间没有ａｎｄ连接。  好像有问题

E选项 sloth which, found in Puerto Rico in 1991, was dated at 34 million years old, made the sloth the earliest known mammal of

was dated是which从句的谓语，made是主句的谓语， found是插入语。这样的话看上去e没什么问题啊
