I've known dozens of honest, intelligent, inquisitive folks claiming to have seen photos of a 1500's vintage Chinese copy of a thousands-of-years old stone tablet containing an accurate map of the entire world, including an ice-free Antarctica.
as far as I can tell, no such photos exist.
Yerp, I know what you mean. Still, the mystery is more as to 'what are they (we) all remembering?' given the fact that the photos can't be identified.
By the way, I think I've seen that too. ;-)
Not to threadjack w/ a non-dino comment, but are you (or your friends) thinking of the Piri Reis map?

Not Chinese (it's said to be made by a Turkish admiral), but it supposedly comes from the 1500s and it depicts a coastline for Antarctica sans the covering sheet of ice.
