Edmontosaurus was among the largest hadrosaurids to ever exist. Like other hadrosaurids, it was a bulky animal with a long, laterally flattened tail and an expanded, duck-like beak. The arms were not as heavily built as the legs, but were long enough to be used for standing or for quadrupedal movement.
Tyrannosaurus equals Edmontosaurus in U3 and in L3 comprises a greater percentage of the large dinosaur fauna as the second-most abundant taxon after Triceratops, followed by Edmontosaurus. This is surprisingly consistent in (1) the two major lag deposits (MOR loc. HC-530 and HC-312) in the Apex sandstone and Jen-rex sand where individual bones ...
Triceratops was a very large animal, measuring around 8–9 m (26–30 ft) in length and weighing up to 6–10 metric tons (6.6–11.0 short tons). [ 23 ] [ 24 ] [ 25 ] A specimen of T. horridus named Kelsey measured 6.7–7.3 meters (22–24 ft) long, has a 2-meter (6.5 ft) skull, stood about 2.3 meters (7.5 ft) tall, and was estimated by the ...
An Edmontosaurus specimen's skin impressions found in 1999. Dinosaur fossils are not limited to bones, but also include imprints or mineralized remains of skin coverings, organs, and other tissues. Of these, skin coverings based on keratin proteins are most easily preserved because of their cross-linked, hydrophobic molecular structure. [72]
Charan captures a wide range of subjects, but he finds the way animals express emotions—much like humans—particularly fascinating. "I want to depict that in my photographs," he shared.

Dakota (specimen NDGS 2000) is the nickname given to an important Edmontosaurus fossil found in the Hell Creek Formation in North Dakota. It is about 67 million years old, [ 1 ] placing it in the Maastrichtian , the last stage of the Cretaceous period .
