History can be a difficult thing to try and comprehend. We are mostly left to look at written accounts and artifacts left behind by people from the past to try and peer through a foggy window into time. Going out beyond that we get into prehistory, the realm of dusting off fossils and trying somehow to piece together the natural history of our planet through the fossilized remains of the creatures that once inhabited past eras before humans were not even a glint in the eye of the universe. The fossil record of course is patchy, fossils are rare, and we have far from a complete picture of the millions of years that preceded our arrival. We are constantly unearthing new species and even whole new types of amazing organisms from the fossil record, and it can be quite wondrous. Yet, every once in a while there is a supposed fossil find that truly is meant to shake the foundations of what we think we know. From humans walking amongst the dinosaurs to mysterious prehistoric giants, here are some of the weirdest alleged fossils and ancient artifacts that should in no way exist.
