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) you know, accepting the way it is
B) sloth, that they found in Puerto Rico in 1991, has been dated 34 million years old, thus making it the earliest mammal known of the Greater Antilles Islands
C) sloth that was found in Puerto Rico in 1991, was dated at 34 million years old, making this the earliest known mammal of the Greater Antilles Islands
D) sloth, found in Puerto Rico in 1991, have been dated 34 million years old, making the sloth the earliest known mammal of the Greater Antilles Islands
E) sloth which, found in Puerto Rico in 1991, was dated at 34 million years old, made the sloth the earliest known mammal of the Greater Antilles Islands

Thanks in advance !!

1. "found in Puerto Rico in 1991" modifies "sloth" rather than "fossills", making A awkard, A out
2. "fossils" disagrees with "has been", B out
3. "fossils" disagrees with "was dated", C out
4. "the sloth was dated" rather than "the fossils were dated" is the meaning of E, E out

D remains

D

A -- confuses "arm of sloth" with "sloth" itself
B -- confusing "this" (finding of fossils) with "sloth"
C -- same
E -- "makes" not "made".. also comma required before "which"

A is correct only as in speaking.

D is the most appropriate in this case.
