Nodosaurus
Nodosaurus ("knobbed lizard") was an herbivorous dinosaur from the Late Cretaceous, the fossils of which are established in North America. Three unfinished specimens have been exposed in Wyoming and Kansas, and no skulls. One of the first armored dinosaurs to be exposed in North America, Nodosaurus was named by O. Marsh in 1889.
This nodosaurid ankylosaur was concerning 13 to 20 feet (four to six
meters) long. It was an ornithischian dinosaur with bony dermal plates
casing the top of its body. It may have had spikes the length of its side
as well. It had four short legs, five-toed feet, a short neck, and a long,
stiff, clubless tail. The head was thin, with a pointed snout, powerful
jaws, and small teeth. It almost certainly ate soft plants, as it would
be unable to chew tough, fibrous ones.
It is consideration that without a club on its tail, Nodosaurus was left with no much in terms of defense. When threatened, it almost certainly dropped to the ground so that only its armored back and sides were uncovered.
