119's "Prehistoric Tank" Edges

While Goliath has human intelligence, the only weapon of his that I could possibly see reliably piercing the armor plates of the Ankylosaurus is the iron spear, and even, he'd have to thrust it with what would be considerable even for a giant- The knives and the javelin heads would likely not be large enough to reliably pierce the osteoderms and make it deep enough beyond them to do fatal damage. The khopesh is a slashing sword, poorly suited for piercing armor. While Goliath's armor would protect the areas it covers at least partially with Ankylosaurus' beak, it would do little against the club-tail or the trampling feet- there was a reason why maces were widely used against armored knights in the Middle Ages- the force will go through the armor and break the bones under it. The same principle would apply here.

Winner: Ankylosaurus
