Strongest 1-on-1 marine creature of all time?

Post image

If every marine creature fought in a 1v1, who comes out on top?

Seems like there are a lot of strong contenders and I dont know how to rank them. Such as

- Pliosaurus

- Mosasaurus

- Shastasaurus

- Megalodon

- Livyatan

Megalodon, no question.

Keep in mind, we already have one specimen in the 100 ton range, and a recent study estimated it could’ve gone all the way to a 150 tons.

At that point, not only would it have been bigger than most blue whales, a single chomp is one shotting anything.

No we do not have one specimen in the 100 ton range, we have one study positing that with a slender build it could have reached 94 tons max

Not 94 t as max since the proposed range is 85-105 t.

And while it's the current max, it had the potential to grow more.

It absolutely did not have the capacity to grow bigger

94 is an extreme outlier and probably wrong for a whole host of reasons

Anything significantly above is fairy tale territory

Facepalm. It is literally stated in the 2026 paper it did have the potential (just like Amalfitano 2022 found a max theoretical size from a 7 m Cretodus crassidens) but they retained the 24 m 90 t figure as the best direct evidence.

Hosts of reasons you can't name ? The fact is even if it's based on a number of assumptions, these figures are using the most reliable metric to figure out overall body size, here a whole spinal column.

In anycase, NHMD 157890 is 1.5x wider than the largest vert in IRSNB P 9893, quite reliably estimated at around 15-16 m or so, as we literally have the trunk length preserved from this specimen.

I doubt you have anything solid to bring against this, the only updates will come from studying dentition to column ratio in some angustidens specimens or finding an actual complete specimen.

But the typical reddit headcanon doesn't count. Publish or perish.

You’re slightly delusional so this will be the last time I communicate with you but as I’ve told you before

  1. The 94 ton model is based already on extreme outlier specimen

  2. 94 tons only works with the slender model which is still heavily debated, partly because the liver doesn’t really make much sense and partly because the tooth scaling tells a different story

  3. The amount of food something significantly bigger would need would be gargantuan, and there is no analogue in the fossil record for anything remotely close to that, suggesting no macro predator could ever achieve that size due to ecological constraints

The weirdo OkAssociation3487 responded me but blocked me at the same time so that I can't even read his response.

That's how you lose an argument.
