Lambeosaurs - Lambeosaurus riverside - A six-ton male lambeosaur (lambeosaurus) rises from a potential threat. In the background a female and her juvenile drink the water of the river. The lambeosaurs were herbivorous dinosaurs of the cretace. In this scene evoking the landscape of Montana in the United States, 75 million years ago, are also depicted now extinct Tremskya ferns as well as flowering magnolias similar to those we know today. Note also the presence of some birds. In a scene 75 million years ago from what's now Montana, a six ton male Lambeosaurus rears onto its massive hind legs in response to a possible threat, while a female and juvenile Lambeosaurus drink near the river's edge. Lambeosaurus was a plant-eating dinosaur known for its distinctive hollow cranial crest, which in the best-known species resembled a hatchet. The purpose of the crest is unknown. Also featured here are Late Cretaceous Period flora including the now extinct tree fern Tempskya and species of flowering Magnolia similar to the Southern Magnolia we know today. Modern birds were just making their appearance, though avian fossils from this period are rare
