a four-ton armored tank that could shatter a predator's leg with one tail swing.

means A heavily armored, plant-eating dinosaur from the Late Cretaceous, built low and wide with bony plates across its back and a massive club at the end of its tail.

from From Greek 'ankylos' (curved, bent, or stiff — the same root behind 'ankylosis,' the medical stiffening of a joint) plus 'sauros' (lizard), so literally something like 'stiffened lizard' or 'fused lizard.' The paleontologist Barnum Brown coined the name in the early 20th century, struck by the way the creature's bones — especially in the skull — fused together into rigid armor.
