 … solid armor and dangerous weapons all deliver the power to stand up to huge predators2

 
But in the world of Cretaceous, other defenders3 come equipped with tools not only to survive an attack but to defeat an opponent. Ankylosaurus is a herbivore designed to kill. 
 
Hell Creek4, Montana. 68 million years ago. Prehistoric5 plant eaters live every day with a target on their back. To avoid becoming dinner, they rely on specialized6 evolutionary7 adaptations, internal armor, advanced designs, and armaments tougher than anything found on animals today. 
 
These are animals that have defenses. 
 
Herbivores do seem to be marvels8 of engineering.
 
Very dangerous, heavily armed, heavily armored targets.
 
A Triceratops can hold its own against almost any predator1. With three horns and a bony shield, even a T-Rex keeps its distance. An Ankylosaurus is completely different. It may be a herbivore, but it has the tools to stop an attacker dead in its tracks.
 
Ankylosaurus was a walking tank—a massively armed and armored animal. 
 
Nine meters long and weighing four tons, Ankylosaurus’s home is the American West.
 
Interesting thing about Ankylosaurus which makes them kind of cool is that their pelvises have been modified so it’s very broad. They have an enormous gut9 and they were probably engaging in what’s called fermentation digestion10 and we see in their uh… like cows and horses and what not in. They use bacteria to break down the soilous material.
