Hybodus will win this battle, as it has heavier weight than Metriorhynchus and is more armored.

[dinosauria101]

Armor?
I agree Hybodus would win here, but as far as I know sharks don't have armor. Would you be able to enlighten me on that?

[6f5e4d]

Oh I referred to the harder scales on sharks, especially since it's sometimes believed metriorhynchids were not as well armored as other crocodilians.

[dinosauria101]

AFAIK, shark skin is like leather, yes. You do have a point there.

And yes, you are correct. Metriorhynchus doesn't really seem to be armored

The shark’s speed and weight is enough for me to give it my vote.
