The Museum’s dinosaur mummy is a fossilized imprint of the carcass of a duck-billed dinosaur. One of the most complete pieces of Mesozoic dinosaur remains ever found, this fossil represents one of the greatest discoveries in the history of paleontology.

This animal’s skin, marked by bumps called tubercles, was similar to the skin on bird feet. The tubercles are larger along the animal’s back and sides and smaller around the joints, which needed to be flexible.
