Dinosaurs and the joy of discovery.

Wyoming – Wyoming and dinosaurs have a long history. Researchers began coming to the state to excavate the animals' fossilized remains well over a century ago, and that work continues to this day. Right now, field workers from Casper College's Tate Geological Museum are hard at work amid rolling ranchland in far eastern Wyoming. They're uncovering the skeleton of a Tyrannosaurus Rex, one of about 50 specimens known to exist. Now a story about dinosaurs, and joy of discovery.
