Description

real tooth, mm 12, of an herbivorous biped / four-legged dinosaur from beak duck.

The Edmontosaurus (reptile Edmonton) lived at the same time as horned and armored dinosaurs, in the upper Cretaceous, when the climate was hot and humid. Like all Adrosauridae (dinosaurs from the "duck beak"), was herbivorous, large (10-13 meters) and grazed between the sub-tropical vegetation, consisting of low shrubs and tree ferns. His remains were found in the Canadian province of Alberta and in some areas of the United States, like Montana and New Jersey.
To eat is served flat beak without teeth, with which large quantities of detached leaves. Inside the mouth edmontosaurus had about 1,000 teeth arranged in parallel rows, which shredded the fiber, and also very woody plants. When one of these teeth is consumed, a new one grew in its place.
The edmontosaurus most likely had some sort of leather bag placed on the nose, which could be inflated like a balloon to produce a particular sound. The other dinosaurs could almost feel the sounds and recognize the typical call dell'edmontosaurus. The bag nasal  probably also served as a visual signal. This dinosaur, perhaps, designed to put good shows in the other males, to warn them to stay away, especially in the season of love. The males of the existing elephants behave in a similar way, using the trunk show as a signal to drive away their rivals that they entered the territory. In some fossil remains of edmontosaurus were found traces of his skin, which was covered with flakes. The edmontosaurus spent much of his time on the ground, walking slowly through the vegetation on strong hind legs, which had the appearance of large pillars adapted to support the weight of the body. I "walk" had three fingers to better distribute the weight on land. "Hands" and "feet" were then fitted with claves like hooves. It is believed that the edmontosaurus were able to swim and it probably useful if returned to get rescued by some danger.
