The "Gallery" section is disjointed. There are too many images here in comparison to the text, so we need to decide how to arrange them better, or which ones we should drop. John.Conway 14:36, 2 April 2007 (UTC)[reply]

Nature of sail

I recently visited the AMNH. While photographing the Edaphosaurus skeleton, I noticed that the spinal processes on its vertebrae had lateral protrusions at various intervals along their length. I do not believe these extensions would be present if they did not serve a physiological purpose. Their presence suggests that the sail of Edaphosaurus was not a simple skin membrane, but may actually have been much thicker, perhaps cartilaginous, in life. Unfortunately, I can provide no further information to support my hypothesis, but I hope you will take this into consideration. 192.160.131.27 (talk) 19:54, 30 November 2009 (UTC)[reply]

It can not be taken into consideration if it isn't published. FunkMonk (talk) 20:21, 30 November 2009 (UTC)[reply]

E.C. Case and Naosaurus's demise

Contrary to what the article claims, while Case's 1907 Revision argues that there are no certainties with regards to the skull of Naosaurus cruciger, nowhere does he claim an Edaphosaurus skull is more likely - if he does, I sure can't find it in the paper. --Ilja.nieuwland (talk) 09:12, 22 March 2023 (UTC)[reply]
