Talk:Nama assemblage

I created a file that might be useful

For when this article gets expanded and can handle more media, this upload gives context to the Nama Assemblage's significantly higher relative rate of faunal turnover:

During the Nama assemblage, extinction rates outpaced origination, leading to a decline in biodiversity.

Thanks, amazing! I'm planning to write more about the article in these next days and nominate it to WP:DYK! Chaotıċ Enby (talk · contribs) 23:10, 16 April 2024 (UTC)

• Starting review--Kevmin § 21:29, 25 April 2024 (UTC)

• Would you be able to clarify what is being stated in the second sentence of the "Biota" section? the middle portion regarding the 550ma seems to be out of place as currently written.--Kevmin § 21:44, 25 April 2024 (UTC)

Hi! I agree it wasn't the clearest way to word it. The Nama Assemblage is often defined chronologically (as the fauna from ~550 to ~539 million years ago, or from the first appearance of Cloudina to the first appearance of Treptichnus), but sometimes on the basis of fauna, with holdover fauna from the previous epochs not being considered part of it, with the chronological definition then called "Terminal Ediacaran biozone". It was mostly to explain why some of the fauna isn't always considered Nama, but that could be further expanded instead in the "Definition" section. I have plans for further expansion of the article (currently in User:Chaotic Enby/sandbox), and I will be happy to reorganize the article and expand it further if needed.

@Kevmin: Based on the above, can this be approved? If not, what needs to happen to get approval? Z1720 (talk) 14:08, 2 May 2024 (UTC)

The sentence in the article is still a bit hard to parse for anyone reading it for the first time, but it does conform to the sources used. The article is new enough and long enough, with reliable sourcing and no close paraphrasing identified. I think we are good to go at this point.--Kevmin § 19:51, 2 May 2024 (UTC)

@Chaotic Enby, Kevmin, Z1720, and AirshipJungleman29: sorry for last minute pull, I checked this set earlier today but only just had access to a computer to edit... I have to say it took me a long time to figure out what was going on with this hook, it doesn't seem to bear that much resemblance to anything that's in the article at first glance. After reading some of the linked articles and based on what Kevmin says on the nom page above, I assume the sentence we're looking at for this one is "The Nama assemblage is bounded from the earlier White Sea assemblage and later Cambrian period by two major episodes of faunal turnover, considered to be pulses of the end-Ediacaran extinction". But I think there are several issues with this that make it not compliant with WP:DYKHOOK at the moment, in that there are aspects of the hook not found in the linked bolded article. Firstly, the hook links to Vendobionta, with no corresponding link to that page in the article; and it pipes that link to "enigmatic early animals", again something not discussed here. Secondly, the last part of the hook says "right before most groups of animals alive today appeared" with a link to Cambrian explosion, once again a mentioned fact and a link not found directly in the article. We know it's the Cambrian period from the article, but would also need to directly say and cite that this means when most groups of animals alive today appeared. I suspect this could be corrected with a few choice cited additions to the article, but would like to see this before we run it on the main page rather than later. A good interesting article anyway, I didn't know anything about this. Cheers!  — Amakuru (talk) 22:10, 16 May 2024 (UTC)

Thanks for the reply, I still have a lot of stuff I plan to add to the article (including a whole section about how the Nama relates to the Cambrian explosion, cf studies such as Darroch et al. 2018) so I probably missed that not everything was in the blurb yet. I'll try to add all of this asap! Chaotıċ Enby (talk · contribs) 08:49, 17 May 2024 (UTC)

Chaotic Enby, it's been over three weeks since your last post and the article remains unchanged, though you have been very active on Wikipedia in the interim. If you wish to continue this nomination, please address the issues raised above in the next seven days. Thank you very much. BlueMoonset (talk) 18:58, 9 June 2024 (UTC)

Thanks, I'm sorry, I completely forgot about this! I'll try to do it tomorrow. Thanks a lot for the reminder! Chaotic Enby (talk · contribs) 21:49, 9 June 2024 (UTC)

At this point, I'm inclined to reject the current nomination and suggest that Chaotic Enby take the time needed to add the additional material they feel is needed. Then the article can be taken though GA and renominated with a stable version to base the nomination on.--Kevmin § 15:34, 11 June 2024 (UTC)

Honestly, probably the best idea. I have found enough material to finish writing the article and expand it to GA, I just need to find the motivation to get myself to do it. Probably a good idea that we close the DYK, and I'll renominate it after finishing the writing, which is planned to include a whole (sub)section about the Nama–Cambrian transition.

Nomination withdrawn, with the anticipation of GA expansion and renomination in the future.--Kevmin § 16:48, 11 June 2024 (UTC)
