Look around you - you're surrounded by stuff. Office supplies, knick-knacks, whatever, it's everywhere, and it can get a little bit mundane. Why not spice things up with these odd, unexpected and often unexplained things that have been found around the planet.

The Quimbaya Airplanes
Scientists are split on whether these Colombian artifacts depict birds, animals - or flying machines. For what it's worth, in 1994 researchers created models based on the Quimbaya Airplanes, and discovered that they could, in fact, fly.
Ulfberht Viking Swords
More than 170 of these swords have been found. They all have the inscription ULFBERHT (or something similar) - perhaps this is one of the earliest examples of trademarking?

The Ubaid Lizardmen

The Tecaxic-Calixtlahuaca Head
This terracotta head was found in Mexico and bears characteristics of Roman sculptures. Perhaps it's an ancient version of an emoji?
Winnipesaukee Mystery Stone
Found in 1872 during the construction of a fence in Meredith, New Hampshire, this totally mysterious stone sits at the New Hampshire Historical Society. Though we think it looks familiar...
