A duck-billed dinosaur named Leonardo has the honor of being the best preserved dino fossil ever found. The find, currently being worked on at the Children’s Museum of Indianapolis still has 90% of its soft tissue intact—including stomach and contents.

And he was found in Montana by a small band of volunteers!

Leonardo is scheduled to go on public display in March, 2014.
