Here's a bit of fun - guess what this is!
Clues: it is the skull of a mythological(?) entity from somewhere in South America, and is totally genuine...sort of. You can tell from the pix below of me holding it that it's pretty sizeable, and the dentition may well guide you along the right path, but will it take you to the correct destination? Let me know what you think - and no cheating! (There's an easy way to find out what it is, but I ain't a-gonna tell ya how!)
