This unusual looking dinosaur lived about 75 million years ago in what became North America and Asia. Parasaurolophus is a member of the “duck-billed” Hadrosauridae family. An herbivore averaging about 30 feet in length (about as long as a bus) and weighing around 5,000 pounds (about as much as a large elephant). Scientists believe Parasaurolophus walked both upright and on all fours. That elaborate head crest was most likely used as an identity display and the newest research points to its function also being to create sound!
