Many loves reptiles and the specificities of their cold predatory behavior.
So, in your opinion, what is most likely the most powerful carnivorous reptile that we know of in history ?

Me. I'm a cold blooded ruthless killer. LMFAO but in all seriousness it'd be some crocodile or crocodylomorph.

Realistically, I think the very rivals in ferociousness and predatory power is between the largest pliosaurs and the largest mosasaurs, though I agree to include some giants crocodylomorph.

If not including dinosaurs. It would probably be the largest Pliosaur ever to have lived, which would be the MoA.

The MoA is not so likely the largest pliosaur, according to Colin McHenry, the macromerus from Cumnor is larger.

That was in the 10 years old reports when it was listed at 18 m...
According to McHenry, the largest confirmed pliosaur weighs 20 tons. In fact, during the history of marine top predators, at any time almost all that ever lived were below 20 tons, and most were 1-10 tons.

Okay then it is Pliosaurus macromerus/Cumnor Monster that was the most fearsome predatory reptile. |

It is a close call between MoA and P. macromerus. In both cases, the sizes are not clear at all. But I doubt mosasaurs reached the same body mass, neither do they seem to have as huge, formidable jaws.

Deinosuchus, Sacrosuchus, and Svalbard Pliosaur.

Pliosaurus m. perhaps ~15 meters and ~20 tons.

Pliosaurus m. perhaps ~15 meters and ~20 tons. P. macromerus is listed at 12,7 m by McHenry and almost 20 tons. There's no pliosaur reaching the 15 m with certainty and I suspect then such a specimen would clearly excess 20 tons. |

There's no pliosaur reaching the 15 m with certainty and I suspect then such a specimen would clearly excess 20 tons. Note the word "perhaps" 12.y is a perfectly good estimate, but with crocodile-like cartilage the 12.7 meter estimate would become ~14+ meters. |

13m is a conservative estimate, and a very speculative one since nobody knows how much of that mandible is reconstructed. 15m is a plausible size for some of the largest pliosaurs (Buchy gave this as "at least 15m", furthermore estimating the mandible at 3m, and noting both P. macromerus and a "recent description from the Kimmeridge bay" also attaining this size. The femoral head suggests 16m)

The thesis of McHenry is several hundreds of pages, nowhere he alludes to some cartilage adding significant body length.
No self-science here...
