Surprise: Duck-Billed Dinosaurs Had Fleshy 'Cocks Comb'

Dec. 12, 2013 — A rare, mummified specimen of the duck-billed dinosaur Edmontosauraus regalis described in the Cell Press journal Current Biology on December 12 shows for the first time that those dinosaurs' heads were adorned with a fleshy comb, most similar to the roosters' red crest.

The most common dinosaurs in North America between 75 and 65 million years ago, duck-billed dinosaurs were gentle giants, about 12 meters long, and filled the same ecological role that kangaroos or deer play today. But no one had suspected that they -- or other dinosaurs, for that matter -- had fleshy structures on the tops of their heads.
