Okay, so apparently fights between crocodiles and great white sharks are entirely possible as crocodiles have been found a mile out into the ocean before. Now, who do you think the victor would be if we take the largest shark to have swam the earth's oceans, Megalodon and put him against the largest croc to have roamed the earth, Supercroc? Also, let's add the monster Liopleurodon to the mix. Who wins between the trio?
 
Supercroc (Sarcosuchus imperator)

 

 
 
 
 
 
 
 
 
 
Stats: 
Name: Sarcosuchus imperator
[Sar-koh-soo-kis im-peer-ay-tor]
Meaning of name: "flesh crocodile emperor"
Nickname: "SuperCroc"
Age: 110 million years
Discovery Site: Niger
 How big did Sarcosuchus grow?
Based on measurements of the skulls and bones, and comparison to recent crocs, Sarcosuchus grew to lengths of 37-40 feet
 How heavy was it in life?
Based on a comparison to living crocs, Sarcosuchus would have weighed about 8 metric tons (or 8,000 kg), which equals 8.75 English tons (which equals about 17,500 pounds!) That is about 10 times as heavy as the heaviest living croc. Why was it so much heavier when it is only twice as long as the longest living croc? Remember that as length increases, body weight goes up by the cube.
 
The huge jaw contained 132 thick teeth. The teeth were conical, adapted for grabbing and holding; instead of narrow, adapted for slashing (like the teeth of some land-dwelling carnivores), and more like that of true crocodilians. Sarcosuchus could probably exert a force of 80 kN (18,000  lbf) with its jaw, making it very unlikely that prey could escape.  It had a row of bony plates or osteoderms , running down its back, the largest of which were 1 m (3 ft) long. The scutes served as armor and may have helped support its great mass, but also restricted its flexibility. 
 It may have come into conflict with Suchomimus, an 11 m (36 ft) theropod dinosaur with a gharial-like snout, whose fossils were found in the same geological formation as Sarcosuchus. According to Sereno,  "because the ancient animal was so large, it could easily handle huge dinosaurs, including the massive long-necked, small-headed sauropods that were common in that African region".
 
 
Megalodon 
 

 
 
 
 
 
 
 
 
 
 
 
 
Stats:
 
Name: Megalodon
Meaning: "Big Tooth" in Greek
Age: Oldest remains are 18 million years old
How big could Megalodon grow? 
C. megalodon could grow more than 18 metres (59 ft) long and is also quite possibly the largest shark ever to exist.
What did Megalodon eat?
 There is evidence that C. megalodon preyed on whales(e.g. sperm whales, bowhead whales, Cetotherium,and Odobenocetops), sirenians, dolphins,, porpoises, pinnipeds, and giant sea turtles. Whales were likely an important prey item for C. megalodon as many whale bones (including vertebrae and flippers) have been found with clear signs of large bite marks made by the teeth that match those of C. megalodon, and various excavations have revealed C. megalodon teeth lying close to the chewed remains of whales.
What was Megalodon's bite force? 
 A team of scientists led by Stephen Wroe conducted an experiment in 2008 to determine the bite force of the C. megalodon and concluded that very large specimens were capable of exerting a bite force of up to 40,131 pounds per square inch (276 MPa; over 5 times greater than that of T. rex), arguably making the giant shark one of the most formidable and powerful predators to have ever inhabited the oceans.
 
 
Liopleurodon
 
 
 
 
 
 
 
 
 
 
 
 
Name: Liopleurodon
Meaning: "smooth-sided teeth"
Age: Between the mid and late Jurrasic period.
 Four strong paddle-like limbs suggest that Liopleurodon was a powerful swimmer. Its four-flipper mode of propulsion is characteristic of all plesiosaurs. A study involving a swimming robot has demonstrated that although this form of propulsion is not especially efficient, it provides very good acceleration - a desirable trait in an ambush predator. Studies of the skull have shown that it could probably scan the water with its nostrils to ascertain the source of certain smells
 
How big could Liopleurodon get?
The discovery of a very large pliosaur was announced in 2002, from Mexico, nicknamed the 'Monster of Aramberri'. A cautious estimate placed this juvenile at about 15 metres (49.2 ft) long. 
 
How powerful was Liopleurodon?
 Pliosaurs were almost uniquely adapted for powerful biting. Estimates of biting force in excess of those produced by any existing animal have been made for (the kitten-like)T.rex based on marks left on the bones of its prey (or scavenged carcases). Pliosaurs were much bigger than T.rex, and better adapted for powerful biting. Think of a modern car, with a monocoque chassis: all relatively thin steel. A pliosaur was big enough to hold a medium-sized car in its jaws, and powerful enough to bite it in half!

Supercroc would probably be beaten right away. 
 
Anyway the Liopleurodon would win. Sure the Megalodon was bigger, but Liopleurodon had a stronger bite force, even stronger then Tyrannosaurus Rex and wouldn't have to come up for air since it can breathe underwater for 3 hours or something. It had thick scaley hide so once it bites the Megalodon which doesn't have any armor plate protection. The fight is over.

I'm thinking Liopleurodon. It effectively has traits from both Supercroc and Megalodon so I think it would defeat the other two. Then Supercroc second and Megalodon 3rd. Megalodon has the least protective skin.

Funny. Megalodon's flimsy skin didn't stop it from eating whales, according to the op. 
Megalodon probably wouldn't survive long on land, so I'm assuming this battle takes place in the open sea. If that's the case, then Supercroc is in Megalodon's domain, and he's not only fighting a bigger fish, but one with a bite force easily exceeding 5 times that of a trex.
 
The real battle is between Megalodon and Liopleurodon. I might give it to mega, but lio's bite is pretty darn intense.

Megalodon.  Think of how sharks have evolved, they've gotten to a point where, evolutionary, they no longer have to change.  They're the perfect predator for the sea, even to this day.  Nowadays, the Orca is the apex predator of the sea, they've even been known to kill great whites.  Usually, an Orca will upturn a shark, flipping it upside down, which, for some reason, puts the shark into a trance (aka, mindf@ck).  However, back in the day, Megalodon's fed on whales.  They would actually attack the fins of whales to hinder their mobility, then pick them off.

You should have included the Predator X in this battle.  No, not the X-Men creatures that eat mutants, there really was a creature back in those times that scientists have actually named Predator X, supposedly, it's been deduced that they were one of the most fearsome predators the sea's ever known.

Meg has the size factor and bite force here, but I feel the liopleurodon is probably a bit more agile and faster, not that hte meg wasn't agile or fast, but i feel the lio was probably a bit faster with more maneuverability.  If meg tags the lio, it will probably be lights out, but lio has a good shot at this.  The supercroc probably goes down pretty quick this fight.

This is not even remotely close. Its a 48 ton shark vs 8 tons crocodile and about 3 tons Liopleurodon and people think Leopleurodon would win? Strange.. very very strange

Also to anyone saying Liopleurodon has a better bite force than T-rex, the bite force of a T-rex is esimated to be little under 75,000 Newtons while the bite force of Megalodon is estimated to be a little above 182,000 newtons. Thats more than double.

Liopleurodon wasn't 3 tons 
They can range from 75-150 tons.

Going with Meg. Supercroc doesn't have the size and I feel Lio will be out maneuvered. Meg has the power, size, and the speed bursts to take this.

Anyone check out shark week this year? Enough with the White Shark crap already. We get it. They come out of the water attacking seals.

Most researches point to the contrary. People tend to based their opinion on the BBC series which was all out of whack, they over-estimated Liopleurodon for whatever reason or generally confuse it with Mosasaur.

Megalodon wins, Supercroc goes down first. Megalodon has the speed and movement advantage over the croc and Liopleurodon would eventually need to come up for air. It would be a brutal fight but it would eventually go to Megalodon.

Liopleurodon is hugely overrated, most recent research suggests it was only 23 feet long and 2.5 tonnes at best;

http://dinosaurs.wikia.com/wiki/Liopleurodon

A better Pliosaur for this battle would be Predator X, the Svalbard Pliosaur. It was actually 49 feet long and 45 tonnes. Predator X could beat Megalodon, neither Supercroc or Liopleurodon can't.

Seeing the battle as it is now, Megalodon would win easily, but if Predator X was in the battle it would win.

What are you all talking about? A crocodile has the most powerful bite in the animal kingdom, imagine a much larger, heavier, stronger, prehistoric version of it. It has incredibly tough skin and armored bone plates that run across his back, its got claws, a tail with such a powerful whip it can do devastating damage, a super long snout so that it can bite from a safe distance, and a tecnique called the death roll (FACT: All sharks drown when their turned upside down). The only advantage that meg has over super croc is sheer size, even to bite meg needs to get dangerously close. Super croc can go on land and in fresh and salt water. Meg vs Super Croc, Super Croc wins hands down. As for Liopleurodon, if it couldn't adapt to survive today, it probably wasn't such a badass back then. Or maybe they all escaped to candy mountain.

Um....guys liopleurodon was twice the size of both those things. That's the real truth, look it up. I'm sorry, but in no universe does a meg not get bit in half by Lio, and super rock has literally no chance in open water. They have no stamina vs sharks that never stop moving and monster so large that it could kill it with a blow from its flipper. Bite force means nothing here. Croc<shark hunting tactics and better adaptation<creature so unfairly large this thread is a joke.

Megalodon should win. Supercroc would be taken out first due to his disadvantage in open waters, if this was near land Supercroc might be able to drag Megalodon, who is vulnerable on land, but it isn't, so he's beat by either of the other two. Megalodon would take out Liopleurodon because of the speed advantage. And Megalodon is quite larger than the two. Lio has stronger jaws, but it might not be able to get many bites due to Megalodon's superior speed. But it won't be that large of a win because Liopleurodon's bites might harm Megalodon pretty bad because the skin is slightly weaker than SC or Lio's.

Not even slightly dude. First off, in megs defense, its called a death ROLL, its not holding anything upside down its spinning. Crocs hunt via waiting and using bursts of energy to catch its prey. Sharks like to dive down far beneath their prey and come up in their blind spot at ridiculous speeds like a bulldozer. How does a swimming crock stand a chance? Probability is low.

Now, meg is 45-60 feet in length, any stats otherwise were the results of a desperate study that suggested something crazy like 70 feet or something. Now these sizes u guys got up there, about 45 feet for Lio....it even says juvenile!!! They're freak in huge and you guys sent understanding this. Its from an era before meg and the super crock. Its the monster THEY are afraid of. Please just look it up before you argue, its very impressive stuff

Abstract

The modern giant sperm whale Physeter macrocephalus, one of the largest known predators, preys upon cephalopods at great depths. Lacking a functional upper dentition, it relies on suction for catching its prey; in contrast, several smaller Miocene sperm whales (Physeteroidea) have been interpreted as raptorial (versus suction) feeders, analogous to the modern killer whale Orcinus orca. Whereas very large physeteroid teeth have been discovered in various Miocene localities, associated diagnostic cranial remains have not been found so far. Here we report the discovery of a new giant sperm whale from the Middle Miocene of Peru (approximately 12-13 million years ago), Leviathan melvillei, described on the basis of a skull with teeth and mandible. With a 3-m-long head, very large upper and lower teeth (maximum diameter and length of 12 cm and greater than 36 cm, respectively), robust jaws and a temporal fossa considerably larger than in Physeter, this stem physeteroid represents one of the largest raptorial predators and, to our knowledge, the biggest tetrapod bite ever found. The appearance of gigantic raptorial sperm whales in the fossil record coincides with a phase of diversification and size-range increase of the baleen-bearing mysticetes in the Miocene. We propose that Leviathan fed mostly on high-energy content medium-size baleen whales. As a top predator, together with the contemporaneous giant shark Carcharocles megalodon, it probably had a profound impact on the structuring of Miocene marine communities. The development of a vast supracranial basin in Leviathan, extending on the rostrum as in Physeter, might indicate the presence of an enlarged spermaceti organ in the former that is not associated with deep diving or obligatory suction feeding.

I agree that the arena may effect who would win, but Super Croc isn't completely helpless in open water. Besides, Sarcosuchus was an ambush predator because it wanted to minimize damage that its prey could cause during a hunt, but it could still fight head on.

Well if you introduce Predator X, it means you should also probably also consider Livyatan melvillei (see above the abstract from the paper describing it). In the scientific community he was the apex predator...
