We don't know everything there is to know about our ancestors, but sometimes we come across objects they've left behind to help us get to know them better. We refer to these objects as 'artifacts.' Artifacts can take on many shapes and sizes. They can be small enough to fit in the palm of your hand, or they can be larger than your whole house! We've seen some amazing artifacts pulled out of the ground during the past century or so, and this video contains some of our favorite examples.
