Throughout recent years, 18,000 of these little Dogu sculpture were found all across Japan. They are between 2 and 10 thousand years old and all look just a little bit different than the next. As to what they meant or represented, no one knows. For a look at another set of sculptures that can be found in droves in various different places, check out number 10.
#15 The Quimbaya Airplanes
The Quimbaya artifacts are some of the most famous artifacts ever found in Colombia and are dozens of little gold items. These were left by the Quimbaya people but the most mysterious part of it all is that these are little mini airplanes. Many believe these little figurines are proof that the tribe had mastered flight or at least knew of how it could be done.
#14 Rat Kings
This is easily the grossest item on the list and looks like it belongs in a horror film. It is basically a clump of rodents that are tied together by their tails. These were associated with plagues and a bad omen, but it is rare to find one as big as this one, which featured 32 rats.
