119's "Screw Soviet Russian, in Prehistoric Oceans, Seafood Eat You!"

Edge: Mosasaur
 * Weapons and Attack Method: The Mosasaur has a large, powerful jaw armed with razor-sharp teeth about the size of a small dagger, and would no doubt have very high bite pressure, easily driving these teeth through bone and shells of its prey, which ranged from ammonites, to turtles, to smaller mosasaurs. Dunkleosteus terelli was a placoderm, characterized by its skull, covered in body armor, with, less true teeth, then a bladed section on jaw, for cutting through dermal armor and bone. Both are formidable natural weapons, however, looking the comparative sizes- and having seen fossils of both species in real life and online, the Mosasaur is larger, and by extension, so is his jaws. Given that the bite strength of the Mosasaur would be even bigger than that of a crocodile, I give the edge to the Mosasaur as it would probably be able to crack through the armor of the Dunkleosteus' skull, and even if it didn't, it could easily tear the unarmored body of the fish clean in half, making for an instant kill all the same. The Mosasaur is so big, on the other hand, the Dunkleosteus can't behead it in one clean shot, having to take several bites to kill it.

Even.
 * Senses: The Mosasaur is believed (admittedly I got this from Wikipedia, but it didn't look like vandalism, so there's probably some truth to it) to have had poor binocular vision/depth perception, though its sense of smell was very good. On the other hand, Dunk also has eyes on the side of its head, meaning like the mosasaur, it had monocular vision- meaning a wider field of vision, but no depth perception.


 * Maneuverability: Dunkleosteus is smaller than the Mosasaur, and can breath under water, unlike the Mosasaur, which has to come up for air. Mosy was agile for a creature of its size, but it cannot match the smaller Dunk. Edge: Dunk


 * Armor: Mosy no doubt had thick scales, however, this cannot compete with the body head armor of Dunk. This will give it greater head protection (though, as I said, the more massive Dunk may still be able to crack it). Dunkleosteus, however, is unarmored on the body, but still, partial armor is better than no armor. Edge: Dunkleosteus.


 * Overall Winner: Mosasaur takes this battle for its superior size, and thus bite power, which might even be able to pierce the head armor of the Dunkleosteus. However, because of Dunk's superior maneuverability and armor, this will be a hard fought battle, with the Mosasaur leaving with injuries- possibly missing a few teeth from Dunk's armor or even having a few chunks bitten out of it.
