>> I suggest that it is not merely a coincidence of survival in the sources that we have more accounts of such remains in Roman times but that this represents an increasing interest in heroic burials at this time. The argument I’m developing in the article I am working on is that in the Greek speaking eastern half of the Mediterranean, and in Greece in particular, it became increasingly common under the Roman Empire for cities to advertise possession of tombs of mythical and legendary heroes in order to compete for prestige and status.

Maybe a precursor of later Christians' fascination with relics.

I'm reminded of this passage from The Name of the Rose:

"So it is, Adso. And there are even richer treasuries. Some time ago, in the cathedral of Cologne, I saw the skull of John the Baptist at the age of twelve."

"Really?" I exclaimed, amazed. Then, seized by doubt, I added, "But the Baptist was executed at a more advanced age!"

"The other skull must be in another treasury," William said, with a grave face.

There’s something about extinct/ancient common ancestors of humans and other species that’s so interesting and exiting.
