アメリカ自然史博物館さんのインスタグラム写真 - (アメリカ自然史博物館Instagram)「Today’s Exhibit of the Day? The Museum’s mummified hadrosaur—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: a rare glimpse at the texture of dinosaur skin. Like the skin on modern birds’ feet, this duck-billed dinosaur’s skin was marked by bumps called tubercles. The tubercles are larger along the animal’s back and sides and smaller around the joints, which needed to be flexible.
