CALEDONIA, MI, August 27-The Non-Destructive Testing Group recently X-rayed a fossilized dinosaur mummy with the Kodak Industrex ACR 2000i X-Ray machine. The full story of this unprecedented find will be chronicled in “Secrets of the Dinosaur Mummy,” premiering September 14, 9:00 pm (ET/PT), on the Discovery Channel.

Leonardo, who will be going on display September 19 at the Houston Museum of Natural Science, is a three-year-old male Brachylophosaurus Canadensis, discovered in the summer of 2000 in Malta, MT.

What makes Leonard so special is that he is the largest and best-preserved dinosaur fossil ever discovered-his body actually mummified, meaning that 90% of his soft tissue is preserved, including skin, muscle, nails and beak.
