I have a slight issue with the line about Stupendemys being the largest turtle ever, and the explicit statement that it was larger than Archelon. This statement is based upon estimated total lengths of over 3.3m, however - Archelon has total estimated lengths of over 4m. The reduced shell of Archelon would make it's mass much less than expected for a turtle of its size, so Stupendemys, with its solid shell, may well have had the greater mass. If mass is the reason why Stupendemys is stated as being the largest, this must be stated as such, as the current statement based upon length doesn't make sense. Regardless, Stupendemys could be stated as the largest Pleurodire known.
With regards to the statement that the Arrau turtle is the largest freshwater turtle in the world, this is also inaccurate given that the giant soft-shells of the genus Pelochelys get bigger. The Arrau could be stated as the largest living Pleurodire. — Preceding unsigned comment added by Salsatron ( talk • contribs) 13:24, 9 February 2011 (UTC)
The size figure for Stupendemys is not "estimated total length", it is the straight-line measurement of a carapace. Straight Carapace Length (SCL) is the most common way to compare turtle size and this is the largest figure ever published. However, one Archelon specimen had a snout-to-tail length of 16 feet (~4.9 meters), and for whatever reason, there are no known measurements of SCL. — Preceding unsigned comment added by 74.103.229.199 ( talk) 17:27, 30 June 2013 (UTC)

I will review this. Before I start reading in detail, may I ask you to take care of the following general points? Thanks!

issues acknowledged and hopefully fixed
As for the phylogeny, while usually recency is not an indicator of quality, it kinda is in this case. As explained in the text, the last major study of Stupendemys, from 2020, included Caninemys material believing it to be the skull, now rendered obsolete by the 2021 paper. This means that the 2020 phylogeny is inherently flawed as it combines characters from two distinct genera not recovered particularily closely by the latest phylogeny.

I added the citation for the Caninemys remains from La Victoria and included Wood's original position as well as how Stupendemys was recovered in 2020 as it was combined with Caninemys. For clarification I also highlighted Caninemys current position in text. Armin Reindl ( talk) 08:55, 7 January 2022 (UTC)
Almost done now. Few last issues:
