Ankylosaurus

Ankylosaurus solved the problem of survival the same way a castle solves the

problem of war: by making the walls so thick that breaking in costs more than

it is worth. Its entire body was encased in plates of fused bone — back,

sides, skull, even its eyelids were armored. Nothing in the Dominion could

bite through it. Nothing could claw through it. And for any predator

stubborn enough to try, Ankylosaurus carried its own answer: a tail club of

solid bone, swung with enough force to shatter legs and crack skulls. It

did not need to be fast. It did not need to be clever. It only needed to

exist, low to the ground and utterly impervious, grazing the plains with the

calm assurance of something that had already won every fight it would ever

be in. The Dominion produced many impressive predators. Ankylosaurus was the

reason most of them looked for easier prey.
