Fact: “Armored ‘tank’—a tail club that could shatter attacker bone.”

Description: Ankylosaurus represents the extreme expression of ankylosaurid armor in latest Cretaceous Laramidia. Osteoderms and spikes covered a low, wide body, while distally stiffened caudal vertebrae anchored a massive tail club capable of high-energy impacts. The skull is short and broad with accessory cranial ornament suited to protection during head-first burrowing or intraspecific shoving matches.

Features:
  - The skull incorporates horn-like osteoderms fused into a protective cap
  - Tail clubs approach ~50 kg in mass in the largest individuals
  - A low center of mass stabilized lateral pushes during combat

Related genera: Europelta, Pinacosaurus, Euoplocephalus
