what is this article about?

I came to this article hoping to find out information about air sacs in birds and it's entirely about dinosaurs--which is not actually about air sacs. Should it be renamed? Could an article about air sacs be written? 0¹⁸ (talk) 02:54, 1 July 2017 (UTC)

This article should just be expanded with more info on birds. FunkMonk (talk) 05:25, 29 September 2017 (UTC)

Can birds breathe through holes cut in their bones?

Sylvia and Stephen Czerkas (who is definitely notable enough for an article) wrote on page 92 of "Dinosaurs: a Global View" (1990) that 18th century studies had apparently shown that birds could breathe through holes cut in their bones, due to their hollowness. This struck me as odd, since I have never read about it elsewhere. Is there anything to this, and even if there isn't, it should be added for historical context. I think MWAK has cited the book before, so maybe he has an idea... FunkMonk (talk) 05:33, 29 September 2017 (UTC)

If you block the pharynx of a bird, but cut his lower leg in half, he can still breath. I can't recall who first performed this, rather sadistic, experiment though.--MWAK (talk) 07:45, 29 September 2017 (UTC)

The book mentions a treatise by Emperor Frederick II, but the date for the experiment is 1758, so seems they are unrelated... If true, worth a mention? Could be nice with a more specialised source, though... FunkMonk (talk) 07:52, 29 September 2017 (UTC)

Frederick would have been just the type :o). However, the 1758 date allowed me to find the mad scientist responsible for this particular unethical experiment: John Hunter who blocked the windpipes of hawks and then cut through their wings. The experiment was carried out in 1758 but only published in 1774, when the text An account of certain receptacles of air in birds, which communicate with the lungs and eustachian tube was read to the Royal Society. Petrus Camper published the same structures in 1773 in the Verhandelingen van het Bataafsche Genootschap. The "air cells" as such were first published by William Harvey in 1653 in his On Generation page 7. See for all this: The works of John Hunter, with notes, ed. by J.F. Palmer. 4 vols., illustr. by a vol. of plates: https://books.google.nl/books?id=X7ITAAAAQAAJ&dq=experiment+%221758%22+John+Hunter&hl=nl&source=gbs_navlinks_s --MWAK (talk) 08:45, 29 September 2017 (UTC)

Very interesting! Could certainly be a good addition here or in skeletal pneumaticity... FunkMonk (talk) 09:56, 29 September 2017 (UTC)

This article should of course be completely rewritten. It consistently confuses the excavations within bones for the diverticula of air sacs with the air sacs themselves. And it doesn't seem to know that many mammals have air sacs too.--MWAK (talk) 17:11, 29 September 2017 (UTC)

Eusaurischia is the first clade with air sac

Eusaurischia (not saurischia) should be mentioned as the first clade with air sacs. Voproshatel (talk) 06:38, 2 November 2024 (UTC)
