About Brachylophosaurus:

Only three complete fossils of the hadrosaur, or duck-billed dinosaur, Brachylophosaurus have ever been found, but they're so amazingly well-preserved that (as paleontologists often do) they were immediately given nicknames: Elvis, Leonardo and Roberta. (The same research team also found a fourth, incomplete fossil of a juvenile, which they dubbed Peanut.)

Although it's named for the unusually short crest on its head (short, that is, for a hadrosaur), Brachylophosaurus stood out more for its thick, downward-turning beak, which some paleontologists take as evidence that the males of this genus head-butted one another for the attention of females.

The most completely preserved Brachylophosaurus specimen, Leonardo, has been the subject of a Discovery Channel documentary, Secrets of the Dinosaur Mummy. Here, it's revealed that Leonardo had a birdlike crop on its neck (presumably to aid in digestion) as well as different-sized scales on different parts of its body, among other unique anatomical features.
