Lambeosaurus

Lambeosaurus is a genus of hadrosaurid dinosaur that lived in North America during the Late Cretaceous period, about 75 to 71 million years ago. It was a large, herbivorous dinosaur, with adults reaching lengths of up to 30 feet and weighing around 5 tons. Lambeosaurus had a distinctive head with a tall, hollow crest on top of its skull, which may have been used for visual signaling or to produce vocalizations. It also had a long, narrow snout and a mouth full of hundreds of small, interlocking teeth, which it used to grind up plant material. Lambeosaurus walked on all fours, but was able to rear up on its hind legs to reach higher branches when feeding. Like other hadrosaurs, it probably lived in large herds and migrated to follow seasonal food sources.
