OG13 SC81 求点醒：earliest known mammal / earliest mammal known

jfire

Fossils of the arm of a sloth found in Puerto Rico in 1991, and dated at 34 million years old, made it the earliest known mammal of the Greater Antilles islands.

A. sloth found in Puerto Rico in 1991, and dated at 34 million years old, made it the earliest known mammal of
B. sloth, that they found in Puerto Rico in 1991, has been dated at 34 million years old, thus making it the earliest mammal known on
C. sloth that was found in Puerto Rico in 1991, was dated at 34 million years old, making this the earliest known mammal of
D. sloth, found in Puerto Rico in 1991, have been dated at 34 million years old, making the sloth the earliest known mammal on
E. sloth which, found in Puerto Rico in 1991, was dated at 34 million years old, made the sloth the earliest known mammal of

这道题上主流的问题都查了也都算懂了，但是看到B选项这个跟其他选项不一样的语序， the earliest mammal known on the island，牛角尖强迫症就犯了。好像大家没提到，这种时候真的会怀疑自己是不是高中英语学漏了点什么啊啊，

求牛牛指点，earliest known mammal 和 earliest mammal known 有没有什么区别，语义上有差别吗？

另外，可不可以顺便举个例子让我理解OG13 SC77中，为什么 “phosphate amount 是个很挫的表达方式，一般用 amount of phosphate”
附77正确句子： A 1972 agreement between Canada and the United States reduced the amount of phosphates that municipalities are allowed to dump into the Great Lakes.

谢谢楼上

the earliest mammal [known on the island],
后半部分[known on the island] 是 past participial phrase 修饰 mammal
意思稍微失真：“在岛上得知的 最早的哺乳动物”

的确是有区别的，修饰语序不一样表达的含义就不一样，亲的钻研精神值得鼓励~~赞~，不过也要提防“钻牛角”。
