A group of paleontologists recently announced that a site in Utah has yielded fossils of some of the biggest armored dinosaurs ever found, and that they were at least 25 million years older than any similar dinosaur type previously found in North America.

A) Same
B) and they are at least 25 million years older than those of any similar dinosaur type that previously was
C) and the fossils are at least 25 million years older than any similar dinosaur types that previously were
D) fossils that are at least 25 million years older than those of any similar dinosaur type previously

In choice A, if we change "they" with "fossils", then Choice A is right?
because - paleontologists announced that "a site ...." and that "fossils were ....."

Please tell me where I am wrong?

nope.

* the past tense doesn't make sense; the observation about ages is still true.
i.e., these fossils are still 25 million years older than xxxxx (and always will be -- age differences don't change), so you have to use "are", not "were".

* the comparison isn't parallel: it's saying that the fossils are older than a dinosaur type.
that doesn't work; you have to compare fossils to other fossils (hence "those of" in the correct answer, in which "those" = fossils).
