There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.
And this is what happened with Megalodon during all these years! One people put a paper with an estimation, latter other people shows that is incorrect, other put other paper and latter is debunked. The size of this shark is very problematic as there are only teeth and a very few vertebrae that managed to be fosillize.
The conversation is very interesting and try to refute those estimations. Using Cretolamna, they propose a maximum size of 13.2 m and 20 tones for the largest known tooth by scientists and of 14.6 m and 27 tones for the largest tooth in private record. Of course this are just the estimations of a few posters there, but they suggest that the work of Dr Shimada is more reliable.
Who knows what will say the next document about this giant shark.......

That's all about it, consider the fact that some megalodons could have just had a proportionally slightly larger teeth that just belongs to a megalodon that is the same size about GHC-6 and has no significant size difference rather than a few cm as no animal of any species has the same proprortions of others
I also doubt the cold water / warm water size difference among these sharks since you quoted that "cold water" topic which is probably referred to that recent study claiming that Megalodons inhabiting cold waters grow larger than their warm water counterparts. I mean, sharks are Migratory animals and the cold water Megalodons are just subadult Megalodons that may have migrated upwards while maturing from the south, like they'd go to South to reproduce and then go back towards the north.
I've made a size comparison related to that study showing the max sizes of warm and cold water megalodon females with a max sized livyatan just for scale

And yes, GHC-6 is an outlier. Any individual of any animal species reaching or surpassing what is considered to be the general max size barrier of that animal species is automatically an outlier.
Leopards that reach or surpass 90 kgs are outliers, just like megalodons that reach or surpass 20 meters in length
Of course some individuals could have obviously proportional larger teeth, this is constant once we extrapolate to very large size, the point is GHC-6 is not an outlier because there are other teeth comparably sized from various parts of the world even available to museums, so 20 m is a natural max size for cold water megs. There are more than one shark approaching 20 m using Perez method in the file I sent you. So nothing such as an outlier.
Yes the 2022 cold water article by Shimada would need a larger sample but it is nothing new in that it has been remarked since a long that meg teeth from temperate waters appeared on average larger.
An outlier is an individu
