Arctic archeological dig uncovers mysterious disks: Science | Alaska news at adn.com: ""The first one looks like a little stone that had some scratch marks on it," said Shirar. "We got really excited when we found the second one with the drilled hole and the more complicated etchings on it. That's when we realized we had something unique.
"We only opened up a really small amount of ground at the site, so the fact that we found four of these artifacts indicates there are probably more and that something really significant (was) happening."
The artifacts were unusual in several respects. They were made of clay, not carved from stone or bone. In the course of the excavations, the team encountered a fine gray clay that could have been worked to create the objects, which were, Shirar said, "definitely hand made.""
