Length: 10 meters
Mass: 1.7 tons
Diet: Fish

Found in northern South America

NOTE: I know this may seem a bit unfair given the gharial's size advantage, but it may need it since the shark has much better weapons

I think gryposuchus wins but the shark still has good weaponry.

I agree Gryposuchus wins, probably due to size advantage. However, the shark may have a chance if it can bite off the snout.

[sharkboy101]

That’s kinda of a dangerous move for the shark.

The only way I see shark standing much of a chance is if it takes chunks from the gharial’s underbelly

[dinosauria101]

Well, maybe not. Alligators and crocodiles have been known to remove chunks of rivals' snouts with no adverse reactions; I could see something similar happening here with a side attack

[elosha11]

The gryposochus doesn't really have a size advantage. It has a length advantage, and a large great white apparently has a bulk advantage, meaning it would be much thicker. Anyone have dimensions for the gharial's jaws. Obviously they are very long, but they are so spindly, it makes the think it could not handle an animal as big or bigger than a large GWS. On the other hand, if the shark decides to attack, its jaws have a much better chance of doing huge damage. Going to give this to the shark for now.

[theropod]

Gryposuchus skulls can exceed 1.4 m

And I think the weight figure proposed in the OP is very suspect. 10 m may be a realistic length ^(link), but a crocodilian that long weighing only 1.7 t is almost impossible, based on extant Tomistoma and Gavialis (largest and smallest individuals) in Erickson et al. 2012, it would be at least 3.5-4 t.

Ah, that makes a lot more sense. To be fair though, Miocene great whites were probably somewhere around Cretoxyrhina sized as opposed to the 1 ton average of today, and maybe it would be better to use them as it's not only more realistic but it might be a mismatch with a modern GWS.
Overall, who do you back in this match?

Well, going by the OP images, the Gryposuchus seems to have false gharial like jaws, as opposed to as spindly as those of the Indian gharial. Maybe it could badly damage a fin given both its weight advantage and the fact that false gharials are generalists.
