Nodosaurus was an herbivorous Ankylosaurian dinosaur from the Late Cretaceous of North America. It was an armored dinosaur that was a tough guy in its day, about 100 million years ago. The fossils were the best preserved dinosaur fossils of all time; it had all the spikes, horns, bony plates, many tiny scales and even some sections of skin.

Nodosaurus had a large, broad body. It was covered with thick bony shields with spikes along its back and tail. The base genome is a soft brown color.  

This dinosaur was not a very social animal, which means that it can live alone. However, it could be in a small group of four or fewer or seven other dinosaurs. A massive animal was about 5.5 meters long. It had a long tail but a tiny head and a tiny brain. 

Nodosaurus was supported by a heavy layer of thick bony plates and knobs that covered its back to protect it from predators. Its front legs were much smaller than its hind legs, and its back was strongly arched.
