Brachylophosaurus canadensis

† Brachylophosaurus canadensis was a Late Cretaceous saurolophine hadrosaurid from the Judith River Formation of Montana and Alberta. Famous for the mummified specimen 'Leonardo,' this large herbivore preserved soft tissue including skin texture and stomach contents indicating a diet of flowering plants. Its low, solid cranial crest distinguishes it from hollow-crested lambeosaurines.
