clu͏st͏er of four͏ la͏rge s͏pi͏k͏e͏s at t͏he͏ end o͏f i͏ts͏ mu͏s͏cula͏r tail. Each
spike could measure up to ninety centimeters in length. The tail
itself was remarkably flexible and powerful, capable of delivering
devastating blows to attackers. Evidence from Allosaurus fossils
shows wounds consistent with Stegosaurus tail spike impacts,
confirming that this weapon was used actively in combat.

Together, these adaptations made Stegosaurus one of the best
defended herbivores of its era, despite its relatively small brain
and slow movement speed compared to theropod predators.
