To tell the story we must start back in the earlier history of the earth when a shallow sea encompassed most of the area around Rangely, 300 million years ago in what is labeled as the Pennsylvania and Permian geologic periods. During this time marine creatures would become fossils and can actually still be discovered around Rangely.
