The Children’s Museum of Indianapolis – Meet Leonardo the World’s Most Complete Mummified Dinosaur




“Leonardo is a juvenile Brachylophosaurus canadensis, a type of Hadrosaur dinosaur. Hadrosaurs are more commonly known as “duckbills” because of their keratin beak. Hadrosaurs were plant-eating dinosaurs. The name “brachylophosaurus” means small crested lizard.  Leonardo is believed to have been about four years old when he took his last breath and collapsed into the water, which helped preserve him.  He was “only” 23 feet long and maybe two tons at the time of his death.

When this fossilized mummy was carefully unearthed from his grave in Malta, Montana in 2001, researchers had one of the first real looks at the skin, scales, foot pads, and even the stomach contents of the behemoths that roamed the planet 77 million years ago.” More from The Children’s Museum of Indianapolis
