I wonder how many people have unbibium floating around in their rock collections out there... From the article: "The first naturally occurring superheavy element has been found. An international team of scientists found several nuclei of unbibium in a sample of the naturally occurring heavy metal thorium. Unbibium has an atomic number of 122 and an atomic weight of 292. In general, very heavy elements tend to be unstable but scientists have long predicted that even heavier nuclei would be stable. The group that found unbibium in thorium say it has a half life in excess of 100 million years and an abundance of about 10^(-12) relative to thorium, which itself is about as abundant as lead." arxivblog.com/?p=385Enjoy
