I put my bet on Liopleurodon because it's much bigger,stronger,and has twice the jaw length of Mosasaurus.However,Mosasaurus is faster and could manage to quick bite the Liopleurodon,just like a Crocodile would do to a shark today.If it did that many times,it could weaken it.But if Liopleurodon gets it's 10 foot jaws with 14 inch long teeth around Mosasaurus,then it would crush it.Game over.Liopleurodon wins!

liopleurodon wins this 8/10 times, its stronger and its jaws had crushing power, mosasaurus was long but lean and its jaws were more snake-like.
a good analogy would be a moray eel fighting with a shark....

Liopleurodon is stronger, but the Mosasaur is longer, ist biggest sea carnivore.

The Liopleurodon would probably kill the Mososaur, only to be picked off by sharks or members of his own species as a reult of his wounds.

The Mosasaur should kill the Liopleurodon because it could keep on biting the flesh off the Liopleurodon and it was faster.

The fast Mosasaur vs the large Liopleurodon would be a good fight. A Liopleurodon could weigh from 0.2 tonnes to 4.87 tonnes. A Mosasaur could be heavier at 7.324623 metric tonnes, but never forget the Liopleurodon's powerful jaws. Both were apex predators in their region and their time and both ate prey of the same size, so, it is tough to say that either should win. But if you want me to tell you, I should say that a large Liopleurodon, should win.
But if the Mosasaur attacked by non-stop biting, ambush or in groups, it would win. This is by my research as a palaeontologist.

Er...no. Liopleurodon was around 100 tons.

Obviously it wins. I wonder why such people make overkill threads such as this :(

Im sorry, but no way liopleurodon is 100 t, seriously. Not even carcharocles, livyatan n "shonisaurus" sikanniensis r DAT large, seriously :)

Yeah right. A <7m long animal is going to weigh 100t.

Look...

1. There are in fact, books that state that Liopleurodon rivalled even today's blue whales in mass.

2. No, it isn't 7 m. That's ridicolously small.

3. You haven't backed up your claims.

4. If you can, please stop speaking in a pirate's language (or perhaps you simply can't speak English well since you're from Italy).

1. There are books that claim Allosaurus was the ancestor of Tyrannosaurus...
2. Based on the largest skull known, 7m is perfectly reasonable.
http://en.wikipedia.org/wiki/Liopleurodon#Siz...
This specimen has been estimated to be 6.39 metres (21.0 ft) in length with a skull length of about 1.26 metres (4.1 ft) and is regarded as an adult individual.
AFAIK, that is the largest Liopleurodon skull known.
3. Read above.
4. Yes, he's Italian.

1) Please, be aware that these books dont even know where they take this info from. Seriously. Not even the good old "liopleurodon" macromerus (which is currently thought to be a pliosaurus species, pliosaurus macromerus, but in my opinion needs a new genus name) has been estimated to be longa than 18 m
Really. Once i saw a book saying TYRANNOSAURUS IS THE ANCESTOR OF ALLOSAURUS (and NOT VICEVERSA, like spinodontosaurus said!!!) XD XD XD
2)Actually the largest remain of liopleurodon i know comes from a specimen estimated to be 6.4 m long. Really. People say liopleurodon is 25 m or so, u r da first person on earth i saw tellin it was almost 30 m!!!! Seriously, please dont believe these fake books

The largest pliosaur found seems to be Predator X at 15 m and 45 tons. This is for now the best described and among the newest large pliosaurs found, with many medias tlaking about and articles.
there is also the pliosaur found in dorset last year, estimated between 12 and 16 m long. it's weight would be estimated here at 12 tons by paleontologist Richard Forrest who seems to be a very bad mathematicians. IT IS IMPOSSIBLE FOR ANY TYPE OF PLIOSAUR? WHICH WERE DENSLY AND HEAVILY BULKED ANIMALS TO WEIGHT A SUCH LOW FIGURE AT 16 M IN LENGHT !!!
In the all cases, Predator X prevals because it had a 3 m skull, the skull from Dorset measuring 2,40 m...
But CAN WE REALLY SAY THAT THERE WERE NO LARGER PLIOSAURS NO 25 M LONG WWD GIANT-LIKE OR EVEN BIGGER ?
The first thing to know about the Liopleurodon of WWD is that it's based on a mysterious lower jaw mandible found in Oxford which would be 4 m long, and so would correspond to a 16-20 m pliosaur (18 m is the most widely accepted) and since, this piece was attributed to an obscur Liopleurodon-like species. The BBC extrapolated that from this species, the largest ever of its kind would have been around 25 m in lenght. Then was the giant male Liopleurodon in the series !
Then, you all know that the Monster of Aramberri was found in 2002.
The excavations aren't finished but what we know for the moment is indicating a very large pliosaur, in the size range of Predator X. Dino Frey, one of the team leader, stated to me in 2008 on his weblog that the Monster was between 15 and 18 m in lenght. Some signs in the remains would indicate that it was a juvenile animal. Some paleontologist claim that it was a pedomorphy, but Frey see no evidence in the material.
Then, there is few bite marks on the skull of the creature. Two of them were from much larger attackers. one of the bite killed the animal. Just one bite was able to kill an at least 15 m long predator...
This mark punctured the pterygoid bone of the skull. The bite mark on this bone has a diameter of 60 mm in the horizontal branch of a 350 mm pteroid. The tooth penetrated from dorsally meaning that the crown alone must have had a length of about 400 mm. Then comes a root which is normally about two thirds the length of a pliosaur tooth and then you just must find the bones to accommodate the ting and do a bit of calculation. It makes a possible 5 m long jaw for the agressor, probably an adult of the species.
You've got here the signs of potentially the largest carnivore that ever lived on the planet.
By the way, Frey said that it was initially thought to be Liopleurodon type but since, they think it was a possible giant kronosaurid.
Frey claims from that these type of giants pliosaurs dwarfed actual sperm whales and exceeded 25 m. In at least one source he indicates possible lenght of 30 m from the size of these bite marks.
it remains speculations, but based on real traces on actual material.
That's the reason why we can assume the probability of such titans.

I've explained about liopleurodon/pliosaurs.

carcharocles Megalodon is already widely accepted to have reached more than 50 tons, and there are good reasons to think it was even larger, especially in the late Pliocene.

Livyatan was probably in the size range of Megalodon, but I'm skeptical about it. we have only one large skull about it.
Yeah, the teeth are enormous but how much of the teeth was anchored in the mandible, like all cetaceans ? Then, it disappeared apparently long before Megalodon.

Shonisaurus sikanniensis is a good rival to the actual Blue Whale as the largest ever animal. Even being slender than we thinked before, shonisaurs were heavy animals, and a 21 m "sika" was surely bigger than most of the baleen whale. And they found isolated bones 30 % larger than the individual described in 2004. Make a calculation...

Then, Blue Whale is the largest animal on record yes, but remember that it's in fact a relatively elongated and slend animal.
Most of the books states that it measures up to 33 m and 190 tons but these are absolute records of old individuals.
In fact, most of the Blue today are between 23 and 25 m and 90 to 120 tons, the population being young. And in fact, 30 m individuals are very rare.

It stays the largest one, but as I explained, some prehistoric creature could have matched it in size.

Moasaur should win because even Leo is bigger Moa is the later evolution it's more updated then the Lioplerudon and faster too

So you are saying that the 'better evolved' Liopleurodon has an advantage, yet say the Mosasaurus would win?
Btw, Mosasaurus is a more recent animal. So by your logic it should be 'better built'.
