Fossil discoveries can often turn up in the most unlikely places. From quarries to Chinese medicine shops, fossils may appear where least expected. This was the case for the species Umoonasaurus, better known as Eric the Pliosaur. The bones of this animal had not only fossilized, but opalized, making them appear like jewels, hence why they were nearly sold to a jewellery shop, if it hadn’t been sold to a business man.
