Pliosaurus Macromerus Info:
Pliosaurus Macromerus was a hypercarnivorous Pliosaurbfrom the Late Jurassic. It was one of the largest predators of Mesozoic era and one of the largest predators to ever live on the history of this planet. It’s average size is unknown, but an average individual was likely similar in size to Pliosaurus Funkei aka Predator X. However, their max was likely 18 meters since the largest skull measured 9 feet long, and like many Pliosaurs, it’s head is 17% of it’s length. The weight was likely between 30-50 tons. Pliosaurus Macromerus’ hunting style is unknown, but likely had a similar niche to Orcas, who hunt prey even larger than themselves. It’s hunting tactics are also unknown, but it’s likely, they hunted from below and shot themselves up, ramming the prey. Which would stun the prey, due to the huge impact, which would make it easier for the Pliosaurus Macromerus to get the killing bite. When hunting larger prey, it’s likely it probably bite the fins/flippers and tails to prevent the prey from escaping. Weighing at max likely around 50 tons, Pliosaurus Macromerus was the top dog of it’s time. It’s bite force is unknown, but it was likely more powerful than Pliosaurus Funkei. Livyatan Info:
Like Pliosaurus Macromerus, Livyatan was one of the largest predators to ever live. It’s modern relative, Sperm Whale. Unlike Sperm Whale, Livyatan had functional teeth on both upper and lower jaw. This likely helped it for hunting whales. Living 9-5 MYA, it coexisted with the Megalodon. Both did compete but likely didn’t fight that often. It’s also likely it preyed on Megalodon! Similar to what Orcas do. It likely rammed it’s prey and used their teeth to kill the whale. It’s likely male Livyatan’s were bigger than females. At max, Livyatan measured 17.5 meters long and weighed 57 tons. Who Would Win? Attachments:

Pliosaurus got downsized so much that this is a mismatch for the whale.

Unfortunately a mismatch.
I would favor the pliosaur 7/10 at parity however due to larger jaws, stronger bite, and wider gape, as well as more maneuverability

Yes, certainly fairer at parity.
We could do a fantasy section parity fight.

This is a mismatch I favour of the levyathan.

I'm so sorry but, ahem...
WHAT!?
For future reference: could you post reasonably reliable sources for size figures in your OPs? Or any source at all and let us evaluate their veracity?

From many sources I heard that Predator X weighed 20-30 tons. So sources say 45 tons but I suggests Pliosaurus Macromerus probably weighed between 30-50 tons. Somewhere in between but definitely not like 10-15 tons, 20 tons seems to be the minimum. Like I said Pliosaurus Macromerus, unlike Mosasaurs were very robust for their size.

I'm fairly certain these aren't reputable sources you speak of, but post them for me anyway.

I can’t post links since I’m on mobile, but it’s from the author of Kronos Rising, Apex Predator Spotlight: Pliosaurus Macromerus, Naish estimate Pliosaurus Macromerus at 15.34 meters. According to Max Hawthorne, it would’ve weighed 30-40 short tons. If it was smaller than it would weigh around 20-30 short tons, but like I said the largest skull found was actually around 9 feet long and since the head is 17% of it’s body length, the estimate of the animal was an enormous between 17 meters and 18 meters long. Weight may be debatable but since a 15.34 meter long Pliosaurus Macromerus weighed 36 tons, a 17-18 meter long Pliosaurus Macromerus likely weighed between 45-50 tons.

Max Hawthorne is overenthusiastic about pliosaurs and probably 90 % of what he writes about them or fossil marine life is suspicious if not utterly wrong.
We have discussed pliosaur size A LOT on this board : there is no direct material indicating a 15 m pliosaur.
The largest material we have suggests animals that ranged in the 10-20 tonnes. And it is way possible the Kronosaurus/Sachicasaurus genus grew larger (at least in skull size) than Pliosaurus.
Don't trust Max Hawthorne and his falacious calculations and "research", he is a novelist fan of pliosaurs for some reasons, not an actual scientific authority in this particular field and he was ridiculed a number of times on FB by actual paleontologists...
Livyatan is definitely far larger than any pliosaur from any genus known so far, by a long shot.

Livyatan is definitely far larger than any pliosaur from any genus known so far, by a long shot. I doubt that, don’t think he’s a Pliosaur fanboy. He had done several things on like how the largest Megalodon was likely very slow for it’s size. Pliosaurs are very rare in remains. It’s very unlikely Livyatan weighed like 50 tons. I mean Megalodon has been downsized, I can see that happening to Livyatan. If so then it’s likely Livyatan was likely around 13 meters long and weigh 30 tons. |

Megalodon has not been downsized, the latest article by Shimada is full of caveats and has been discussed a lot lately. Be assured this is not the last study about its size.
Livyatan's skull is as wide as the skull of a typical 15-16 m Physeter which typically weigh around 40 tonnes. If it did not reach 50 tonnes, it was not far.
There is nothing to suggest to downsize it as of now.
If anything, this is the pliosaurs specimens that have been downsized a lot with new kniwledge about their anatomy and proportions (Predator X = 15 m = Pliosaurus funkei = 10-13 m), and while we probably don't have the largest specimens in each genus, all the larger individuals we have from ANY genus and species are way behikd Livyatan and megalodon's most conservative estimates.
He is a pliosaur fanboy, the guy passes it time to make (idiotic) memes and poemes about pliosaurs. Sorry but don't expect to be considered seriously if most of your sources are the writings of a guy who explains on YT channels that pliosaurs and mosasaurs are extant...
His writings about megalodon are downright pathetic, he even publishes himself on some obscure journal in order to appear like some authority.

And yes it has been downsized, it has been agreed by the scientific community. |
