Urea in Triassic therapsids
You say that "Kermack & Kermack (1984) describes urea and uric acid." Page reference, please? The authors say in the introduction that they will "only discuss soft parts when their nature can be unequivocally inferred from the skeleton (for example: the position of the tympanic membrane)." This would seem to preclude a treatment of excretion, and I certainly can't find one. Peter M. Brown (talk) 19:15, 19 January 2011 (UTC)


 * Is there another book by Kermack & Kermack? I distinctly remember their saying that mammals excrete urea while "reptiles" excrete uric acid. This was in an introduction, and the rest of the books was about bones, mainly of extinct synapsids. --Philcha (talk) 19:48, 19 January 2011 (UTC)


 * Well, there's Early Mammals, 1971, which I haven't seen.

There are plenty of sources you could use for the claim that most extant mammals excrete urea (but see Uric_acid on the kangroo rat) while extant diapsids excrete uric acid. What a tortoise excretes seems to depend on environmental conditions. Peter M. Brown (talk) 22:26, 19 January 2011 (UTC)


 * It may have been the 1971 book, as I think I read it in the mid-1980s so it probably wasn't the 1984 book. --Philcha (talk) 09:23, 20 January 2011 (UTC)


 * Peter, I found a clear but comprehensive account Comparative Physiology of Urinary Excretion; Bodil Schmidt-Nielsen; The Physiologist (Nov 1962) Volume 5 Issue 4 pp 257-263; The American Physiological Society.
 * Now what WP article were we discussed, so I can included as a ref? The citation looks useful for a lot of articles. Thanks for making me Googling! --Philcha (talk) 10:03, 23 January 2011 (UTC)
