Talk:Cretaceous–Paleogene extinction event

message: The second sentence of the article is interesting but puzzling. Why would ectothermic species be advantaged rather than disadvantaged by their lack of ability to regulate their own heat?
Not sure, and it the distinction only seemed to matter for animals over 55 pounds. I assume it's because endotherms have higher food and water requirements, which would make it much harder for large ones to survive under such conditions. Their habitats would have been destroyed, and with them would have gone their food and water. If they didn't die immediately, they would have starved or been poisoned by food, water and air tainted with sulfur and other nasty things by the impact. Sumanuil (talk) 22:12, 27 January 2019 (UTC)
replies: text: Was the sea turtle not the only tetrapod over 55 pounds to survive? With only one example, it's impossible to say anything about any particular quality such as ecto- or endothermy. Firejuggler86 (talk) 02:22, 24 June 2021 (UTC)
thread_title:  Why did only ectothermic large tetrapods survive the extinction event? 

message: Prior to the 2021, that's results of end Cretaceous when asteroid hits the Mexico did happen to 66 million years ago, but according to 2021's paper by Bland et al., they gave it to update the Cretaceous stage was 146-67 million years ago (Early Cretaceous from 146-101 Ma; Cenomanian from 101-94 Ma; Coniacian from 90-86 Ma; Campanian from 84-75 Ma, Maastrichtian from 75-67 Ma).
:You have to provide a reference, not just change the text so that it no longer reflects the source cited. It would be best to give the source on this talk page so that it can be discussed. It will probably take more than one paper to gain general acceptance of revision of the dating of the International Commission on Stratigraphy. Dudley Miles (talk) 16:02, 13 July 2021 (UTC)
replies: text: It would also be great if that sentence would be rewritten, right now it's an unintelligible blob that says nothing. What's the "that's results of end Cretaceous when asteroid hits the Mexico did happen to 66 million years ago, but according to 2021's paper by Bland et al."? What should it mean?

thread_title: Notes to update Cretaceous stage

message: Citation 5 is a photography book, and so doesn't really seem relevant to the statements connected to it,
'With the exception of some ectothermic species such as sea turtles and crocodilians, no tetrapods weighing more than 25 kilograms (55 pounds) survived'

thread_title:  Citation 5 

message: I think at the least a brief mention is warranted. It's featured in 2022 in science like so:
A study indicates a substantial decline in dinosaur biodiversity millions of years before the Cretaceous-Paleogene extinction event.
There may also be more info in the latest section of Timeline of Cretaceous–Paleogene extinction event research not yet included in the article. Please check that too.

replies: text: This issue is discussed in the article, which states that there have been some studies showing a decline in diversity in the late Cretaceous and others no decline. This is one more regional study and does not seem significant enough to warrant mentioning.  Dudley Miles (talk) 23:01, 28 November 2022 (UTC)

message: I just finished a large edit in visual editing mode and added dozens of new papers like "Deccan volcanism caused coupled pCO2 and terrestrial temperature rises, and pre-impact extinctions in northern China" and "No post-Cretaceous ecosystem depression in European forests? Rich insect-feeding damage on diverse middle Palaeocene plants, Menat, France". After I submitted my edit, I looked at the Citations section and the papers I added were nowhere to be found. After several hours of work. What the **** happened?! How did this glitch happen??? I remember copying and pasting every link to single reference I added into the citation tool!!! Is there any way to recover my work so I do not have to do it all over again???!!! Anteosaurus magnificus (talk) 01:18, 19 November 2023 (UTC)
replies: text: I do not know about visual editing mode but my method in standard mode is to click preview first to check and paste and copy the revised article into Word if there looks like there might be a problem. This usually works to provide a backup, but not always. Dudley Miles (talk) 08:54, 19 November 2023 (UTC)
