Some of the world's treasures are good at hiding in plain sight. I'm not talking about those times where piles of cash or jewelry were left in an unassuming bag, but that has certainly happened too.
Instead, I'm referring to the ways that fascinating and even mind-blowing things can look fairly normal at first glance.
Fortunately, we not only have pictures of these curious finds, but enough context to explain what's so great about them.
