A group of fossil hunters uncover not only the bones of a 77 million year old dinosaur, but its mummified and fossilized 'body'. After excavating the duckbill nicknamed 'Leonardo', scientists begin a battery of tests including a radiographic autopsy. Journey along with a team of paleontology experts as they make several astonishing discoveries including the creature's last meal and never-before-seen internal organs. Leonardo is a young Brachylophosaurus, a four-legged plant-eating duck-billed dinosaur, the very first juvenile of the species discovered with extensive skin. He was approximately three to four years old when he died and would have been 20 feet long, weighing about 2,000 pounds. From high-tech testing of Leonardo’s remains, scientists have positively identified what a plant-eating dinosaur ate – something that has never been done before. Leonardo’s last meal consisted largely of leaves which included ferns, magnolias and conifers. Additional analysis has confirmed at least 40 different types of prehistoric plant pollen preserved in his stomach. Since most dinosaurs were herbivores, this find is an incredibly important step in learning more about the creatures’ lives on the planet.
