You know I get mad when other people post lousy photos, then I am too lazy to post a good one. Actually for some reason, perhaps because the mark is so deep, my camera doesn't want to focus correctly. In any case it is an animal, it looks like an echidna, but considering it is Brazil, it guess it must be a giant anteater. It has a very pointed nose, and little feet.
But that must be the same mark, although it is unfortunately and unknown maker.

Personally I would have preferred a Phrygian cap.
