the skeletons of the dead

With the grammar corrections, yes, it is meaningful. Bones are preserved in many types of graves.

Yes, but I would change it.

These graves still [preserve / contain / hold] human skeletons.

Or
Human skeletons are still preserved in these graves.

Why? What is your objection to the original (as corrected)?

The sentence, "These graves still preserve the skeletons of the dead inside them.", is correct grammatically, but it doesn't sound right usage-wise - no one would say something like this in English. The problem with it, as I see it, is that it is too obvious, kind of hitting you over the head with things that are overly correct, like saying: "A graveyard has graves in which there are dead bodies

I don't agree at all, I'm afraid. There could be all sorts of reasons for wanting to point out that graves were still intact.

"skeletons of the dead" is redundant in this context. Graves would not contain skeletons of the living.

I think when it comes to literary writing, everything is possible.
What is trivial and superfluous for someone, may have deep meanings for another.

I would expect such comments from a high-school teacher correcting a five-paragraph essay.

Thank you

I'm sorry for the grammatical mistakes; I was half-asleep.

If everything is possible, what's the point of submitting your question to the forum at all? Whatever it is, it's possible!
