Tarzan, the lord of the jungle, apparently went all the way to the Maya area as well, and probably to a Tikalish site (was it Tarzan that inspired Mel Gibson?). However, it seems to take place on an island. Cozumel perhaps?
I wonder how they got this obsidian or chert knife to resemble something made out of metal? Did the Maya have connections with the Late Neolithic flint dagger knappers in Scandinavia? This must be something the 2012ers can look into since they fancy transatlantic connections.
