But, as we have discussed VERY EXTENSIVELY on the relevant thread about mosasaur size, jaw or skull length being only 10% of total length is not a reasonable assumption, and certainly not consistent with the more complete mosasaur skeletons Russell (1967) actually figures. Russel made that claim in one of his tables, but never seems to have provided evidence for it. Classic example of how not to cite something, citing an assumption made in a paper that said paper didn’t actually support with any data. Even in the comparison you show, the jaw seems to be clearly over 2 m long, not 1.7 m as the one in the source you cite. And even irrespective of that, are you really under the impression the reconstruction from prehistoric wildlife is otherwise good? Again, how about some scepticism? |

I found only 1 post concerning a mosasaur there, and it had nothing to do with Russell. 2: Error on my part 3: It seems overall consistent with other restorations |

Oh, okay.
The Bunker Tylosaurus seems to have a skull almost 1.8 meters.
Scaling from those proportions, the Mosasaurus is about 14 meters

1: what creature wrote
2: No, error on the part of whoever made that comparison for PW. This only means that you need to be a bit more sceptical about these things. Pretty much every time I take a closer look at one of your comparisons, this happens. Now I couldn’t care less about "mosasaurus vs male megalodon", but I do care about the quality of the content here, and I think a certain minimum standard for quality and reliability should be implemented.
That includes doing some proper research for comparisons, at least so far as to check that whatever they depict has not already been obviously debunked on this forum.
3: It’s an abomination. Not a surprise, many of the silhouettes on PW are. You have the whole wide field of paleoart at your disposal, and you chose to use that? w h y ?

So, with everything in mind, here's a better scale, using Hartman's Tylosaurus skeleton as a stand in for the Mosasaurus  |
