CHICAGO -- Scientists are x-raying one of the stuffed lions at the Field Museum this morning.
They want to know whether a valuable artifact may be hidden inside.
Last year, they discovered that there's a real lion skull inside one of the stuffed lion's heads.
It may be from the legendary man-eating lion that terrorized a railroad camp in Kenya more than a century ago. That lion was killed by a bullet to the head.
Researchers used a hand-held x-ray to examine the skull, and look for a bullet hole that matches the original wound.
