When it comes to nature, there are so many things left undiscovered. Every other week, we hear about a new species being found, an old extinct animal coming back into the world. We read interesting stories about nature all the time, like when a 392 year old shark was discovered or when a study was done that showed that sometimes octopus punch fish for no reason other than spite.
There are always more facts to learn about the animal world. And today, you're about to learn about one of nature's mysteries. Thanks to @AlexPetrovnia, we had taken the time to thoroughly look into this mystery, you're about to learn about the truth behind why we don't find fossils in the Appalachian mountains.
