Leonardo is a 77-million-year-old Brachylophosaurus, a duck-billed dinosaur whose skin, muscles, and stomach contents were preserved in exceptional detail. He's a dinosaur mummy - not wrapped in bandages, but naturally desiccated before fossilization. Volunteers found Leonardo in 2000 on a ranch near Malta; the Guinness Book of World Records certified him as the best-preserved dinosaur ever discovered. The Great Plains Dinosaur Museum was built to display him. The museum is small and underfunded, staffed largely by volunteers, but its collection is world-class - all found within a few hours' drive. The Hi-Line of Montana, that lonely stretch of US-2 across the northern prairie, sits on some of the richest dinosaur beds in the world. Farmers find bones in their fields. Ranchers stumble on skulls. Leonardo is the star, but he's not alone.

His body was buried quickly in fine sediment, before scavengers could disturb it and before decomposition could destroy the soft tissues. Over millions of years, the skin and muscles desiccated and mineralized, pres...
