Sentence Correction (SC) | Re: QOTD: Fossils of the arm

Hey,

I've a question regarding the last part of answer D:

"D. sloth, found in Puerto Rico in 1991, have been dated at 34 million years old,making the sloth the earliest known mammal on "

So, "making" modifies "Fossils of the arm of a sloth". Isn't the placement a bit far away? I thought the modifier should be placed as close as possibile.

Cheers
