Sauropterygian vivipary

I think it's worth a mention that a fossil of a gravid Keichousaurus hui found in 2004 (pictures) has shed light on sauropterygian reproduction. More here. --Anshelm '77 (talk) 23:14, 5 December 2007 (UTC)[reply]

Error in the first paragraph

In the first paragraph it says that xenopsaria survived the End-Cretaceous extinction event. This seemed odd so I followed the link that was referenced and it says that xenopsaria was the only lineage of plesiosaurs that survived into the Cretaceous. I changed the wording so hopefully it is more clear now. — Preceding unsigned comment added by Paleononomous (talk • contribs) 18:45, 6 September 2017 (UTC)[reply]

Pantestundies placement on the phylogenetic tree.

Pan testundies has genetically been shown to very likely be a diapsid reptile (which is not disputed here) but it also has been shown to most likely be a sister clade to archosauriforms or at least closer it them than just a stem-saurian clade.

I hope my points influence the change of the cladogram on this article. 좀비 브렌다 (talk) 14:52, 8 January 2022 (UTC)[reply]
