This article is about Steller's sea cow, a large sirenian that went extinct in modern times. I believe this article's up to FA criteria   User:Dunkleosteus77 |push to talk  06:37, 22 January 2017 (UTC)[reply]

• Will read through this soon, but at first glance, I see somewhat serious problems, but since you usually work fast and effectively, I think they can be worked out. FunkMonk (talk) 13:38, 22 January 2017 (UTC)[reply]
• First, it is a bit messy to combine all info about physical features, biology, and ecology, into one large section, it would be better to keep them in separate section, as in virtually all other articles, to keep focus. Now the section jumps wildly between unrelated subjects.

split   User:Dunkleosteus77 |push to talk  17:08, 22 January 2017 (UTC)[reply]

• You are combining a section that should be abut distribution facts with unconfirmed "sightings" long after the confirmed extinction date. Info about such "sightings" (and anything else not based on facts) should be moved to the extinction section, as they have nothing to do with the confirmed historical range of the animal.

done, but I kept the part about Turner in the range section, and anything talking about its range up into the 1800s.   User:Dunkleosteus77 |push to talk  17:08, 22 January 2017 (UTC)[reply]

• The article seems quite short, but I guess not much is known about this animal. Have you looked through Google scholar and similar for further sources?

I'll get to expanding later.   User:Dunkleosteus77 |push to talk  17:08, 22 January 2017 (UTC)[reply]

• The notable fact that it had no finger bones is not mentioned, which also makes me uncertain about the comprehensiveness of the rest of the text. Perhaps there should be more purely descriptive info about the skeleton, all we have left of the animal.

Found this but it's really technical, and I can't understand a word of it. Think you can help?   User:Dunkleosteus77 |push to talk  04:30, 27 January 2017 (UTC)[reply]

I think you can ignore the detailed description section of that article (unless you find something that is udnerstandable) and jump straight so summarising interesting bits of the conclusion and discussion sections of that article. FunkMonk (talk) 16:12, 28 January 2017 (UTC)[reply]

added a paragraph   User:Dunkleosteus77 |push to talk  04:30, 29 January 2017 (UTC)[reply]

• It appears the only known drawing from life was made by a Friedrich H. Plenisner[4], yet this article credits Steller himself. The drawing shown in this article also appears to be of uncertain origin. If your sources discuss the circumstances of these illustrations, it is very important info to add.

You mean add it to the caption or to the article?   User:Dunkleosteus77 |push to talk  17:08, 22 January 2017 (UTC)[reply]

To the article, but the caption would of course have to be modified accordingly. There are two issues that need to be handled: there were drawings made originally by Plenisner, which seem to be lost, and the drawing that is now in the infobox may be one of those. No other drawings of actual specimens seem to exist, and none were drawn by Steller himself. FunkMonk (talk) 17:37, 22 January 2017 (UTC)[reply]

The caption does say "thought to be". Also, his full name is Friedrich Plenisner, right?   User:Dunkleosteus77 |push to talk  21:35, 22 January 2017 (UTC)[reply]

The circumstances? They got shipwrecked. this link has a lot of info but I'm not sure exactly what is relevant. Should I talk about their first sea cow hunt?

• Why does the intro begin with "the"? Glancing at the sources, few if any say "the Steller's sea cow", but you use it throughout the article. We should follow the majority of the sources.

Some people use it, some people don't. Since it starts with the name of a person, it could go either way, and I think it's alright. Do you still want me to continue?   User:Dunkleosteus77 |push to talk  17:08, 22 January 2017 (UTC)[reply]

• The first sentence reads "The Steller's sea cow grew to at least 8 to 9 m (26 to 30 ft) in length as an adult" I think that this wording doesn't work grammatically and is awkward prose. Something can't grow to 'at least' a range of sizes. 'at least 9 m' or 'sea cow grew 8 to 9 m in length' could work, or some other wording, but the current wording is not good I think.  InsertCleverPhraseHere  20:08, 22 January 2017 (UTC)[reply]

• " In 1811, naturalist Johann Karl Wilhelm Illiger placed Steller's sea cow under the genus Rytina, which many writers at the time adopted. However, the animal had already been classified long before this. Zoologist Eberhard August Wilhelm von Zimmermann had described its specific name as gigas in 1780, but placed it in the genus Manati. Biologist Anders Jahan Retzius placed it under the genus Hydrodamalis, 17 years before Illiger had described the sea cow as Rytina. He, however, described its specific name as stelleri, as Steller was the first person to describe it.[4] The name Hydrodamalis gigas was first used in 1895 by Theodore Sherman Palmer.[1]" What's the point of summarising this history in the wrong order? You should describe it in chronological order, otherwise it will be needlessly confusing to readers.

• I found an online version of Stejneger's book about Steller's voyage[6], perhaps there is something useful that could be added. In any case, it contains a now public domain reconstruction of Steller dissecting a sea cow, which I have added, as I think is relevant enough (mentioned here[7]).

• Having read the range section again, I still think the late survival claim by Turner is way too unreliable to have in a section that should reflect scientific consensus, not speculation. There must be a reason why the IUCN accepts an earlier extinction date, and we should reflect the consensus view here. All speculation on survival past 1768 should be placed under sightings. Furthermore, it is already mentioned earlier in the section that the sea cow existed around the Near Islands, so the Turner sentence doesn't add anything at all about the range, and therefore doesn't belong in that section, regardless of how reliable it is.

moved   User:Dunkleosteus77 |push to talk  00:49, 12 February 2017 (UTC)[reply]

• I would further suggest that you don't muddle up the info on the accepted extinction events with that about later sightings, and instead give later sightings their own header ("possible" or "claimed" sightings, to make it clear). See for example the similar section[8] in woolly mammoth. It is very important that we don't mix accepted views with fringe views haphazardly.

it's not a book, it's the amazon summary that somewhat analyses the book   User:Dunkleosteus77 |push to talk  00:49, 12 February 2017 (UTC)[reply]

• To be honest, I don't see a compelling reason why the pop culture section is even needed. Apart form the documentary, none of the entries are even about the sea cow, but only briefly mentions them. But I won't push for removal unless others do.
• Again, there are still text under description which is not about physical description, but behaviour and ecology, such as "The forelimbs, according to Steller, were used as a sort of holdfast to anchor itself down to prevent being swept away by the strong nearshore waves around their habitat." and "Their large size was probably an adaptation to reduce their surface-area-to-volume ratio and conserve heat. Based on the larger average size of Pleistocene specimens from the Aleutian Islands, it has been hypothesized that the growth of Commander Island sea cows was stunted due to the marginalized environment with a less favorable habitat than the warmer Aleutian Islands."

• Any reason why the text udner "Commercial value" isn't chronological? You start by mentioning uses today, then jump back to the 1700s, and then forwards to the 1800s. It is especially puzzling, since the last paragraph about skeletons in museums seems very fitting right before the text about use of the bones today.

that's basically the cladogram version of the phylogenetic tree, I just lumped all the Dusisiren together instead of making individual branches for each one. Same basic idea's conveyed here   User:Dunkleosteus77 |push to talk  21:30, 6 February 2017 (UTC)[reply]

I'm afraid I disagree. The source shows the dusisiren as a paraphyletic taxon, and suggests that H. Gigas and some dusisiren are actually more closely related than the dusisiren are to each other.

Support. I took the page numbers back out of the Whitmore citation, after asking elsewhere how this situation is usually handled. At Broad-billed parrot, for example, the reference Hume 2007 is 76 pages long, which is too much for a reader to search through for a citation, so for that reference short form citations were used to point directly at the pages cited. For the shorter articles this wasn't done. Personally I'd prefer to see every citation supported by a page ref directly to the pages the reader would need to see, but that's not a FAC requirement. For Whitmore, since you're using it to support multiple facts, it's not appropriate to put in the page numbers, and that's why I deleted them.

• More comments will follow tomorrow. It appears to be a interesting, well-researched article. So far I see two general problems:
  • Language and Prose; understanding the article is sometimes not as easy as it should be, at least for me (I am not a native speaker though).
  • Detail. Of course, I don't have a general objection against detail, but if you state something like "on the proximal end of the anterior side of the radius was a tuberosity which connected to the brachialis muscle", you should also add why this specific information is notable. Without this information ("this is important why …") the reader will not have a chance to learn something from it, and might get the impression that he is flooded with unnecessary, unimportant and random detail. --Jens Lallensack (talk) 21:18, 7 March 2017 (UTC)[reply]
• The heart of Steller's sea cow was detached from all sides, and enveloped in a loose pericardium which formed a cavity in the thorax; so, instead of facing perpendicularly, it made an oblique angle to the back. The base of the heart was surrounded by a 1.3-centimetre (1⁄2 in) layer of fat. The pericardium was fastened to the inner wall of the diaphragm. The lungs were white and extended from the chest cavity into the abdominal cavity. They were encased in a thick membrane and were, like the heart, detached. The liver had three lobes, one of which was small, anvil-shaped, and situated between the other two lobes. It was encased in a fibrous membrane. The gallbladder was absent, but it did have a common bile duct. The kidneys were large, measuring 81 centimetres (32 in) in length and 46 centimetres (18 in) in width. The stomach was also large, measuring 1.8 metres (6 ft) long and 1.5 metres (5 ft) wide. The entirety of the intestinal tract was 151 metres (500 ft) long.[11] – I feel a bit uneasy about this whole paragraph. Again, a lot of detail, and the question if everything is notable enough. But what bothers me the most: This is based on the original historical account of Seller himself, from 1751. I do not want to say that this information is flawed, but basing a biological description on such a historical account is close to original research, since the content has to be translated into the modern biological context. And you have to decide yourself which parts of this information are notable in this modern context. For example, you elaborate which organs are detached, but is this observation even specific for the species, or rather a common trait in mammals (if so, the information would be worth nothing here)? In my opinion, it would be much better not to use the historical source directly, and instead rely on recent scientific reviews of these historical sources (e.g. Forsten and Youngman 1982, which is not cited in the article yet).

Other details you give however are absolutely fun, and I really don't want to see them removed. The problem is that the selection of this information appears arbitrary.

• The dating may be skewed due to the marine reservoir effect; the large reserves of C14 in the oceans cause radiocarbon-dated marine creatures to appear much older than they actually are by several hundred years, but the size of the necessary correction is not know; it has been estimated to be between 450 and 1,000 years. – First I would suggest making two sentences out of it. Second, "it has been estimated to be between 450 and 1,000 years", do you mean the "size of the correction"? If you mean the fossil itself, you don't need to give to datings.

To determine the reliability of the site, we need to know what sort of fact checking they do. You can establish this by showing news articles that say the site is reliable/noteworthy/etc. or you can show a page on the site that gives their rules for submissions/etc. or you can show they are backed by a media company/university/institute, or you can show that the website gives its sources and methods, or there are some other ways that would work too.

Just a few things I noticed:

• Description: "Its large size was probably an adaptation to reduce its surface-area-to-volume ratio and conserve heat", in the first paragraph of the description section, links to Surface-area-to-volume ratio#Biology. While this is technically correct, it may be more helpful to link to the specifically biogeographical instantiation, Bergmann's rule, since as far as I know all adaptive interpretations of the sea cow's massive size have suggested this particular driver (heat conservation) rather than any of the others mentioned at the current link (nutrient exchange, buoyancy, etc.).

• Description: In the second description paragraph, the length of the bristles is given in inches, converted to cm; all other measurements are given in cm, converted to inches. I assume that this is due to difference of usage in sources, but at least the length of the tongue is cited to the same source as the bristles (translation of Steller's original), so maybe a double check re "original" units might be good here.

Also, the available seagrasses in their range, Phyllospadix spp. and Zostera marina, were probably too tough or occurred too deep for Steller's sea cow to consume." This also seems contradictory - it may have fed on seagrass, but the evidence suggests that this was not possible. I would delete.

• More to follow, but from what I have read so far I am inclined to oppose. The article cites a translation of Steller's original paper, even though the translator expresses doubt about its accuracy and it is an original source which is probably only accepted in part by modern researchers. An example is the statement that sea cows were monogamous. It is unclear how Steller could have known, and a statement that they were apparently monogamous in the main text becomes definite without the "apparently" in the lead. Dudley Miles (talk) 23:35, 15 March 2017 (UTC)[reply]

Closing comment: This has been open for nearly two months now, and we have had a lot of commentary but we have two fresh leaning opposes, plus a remaining earlier oppose. Despite the support this article has received, I don't think we have a consensus that this meets the FA criteria, and the opposes are certainly valid ones. Therefore, I am archiving this nomination as I don't think we are close enough to promotion after a long time at FAC. This can be renominated after the usual two week wait, but I would suggest working on this away from FAC in that time with those who have made suggestions, and bring it back when the work has been done.

• Current ref 1 has a major red flag "Überarb, Germany: Books on Demand". What makes this reliable?

Well, "books on demand" is usually a self-publishing service. We consider self-published sources to be problematical, and often unreliable. See Wikipedia:RSSELF.

• Portrayals in media section - why were these specific protrayals chosen out of other mentions? Per MOS:POPCULT, we need to be careful with these sorts of sections.

But what do they tell us about the subject of the article? What commentary in third-party sources discuss how these poems/etc help our understanding of the article subject?

For me, the current European/aboriginal split doesn't quite work; you could change it to something like "Pre-European contact" and "19th century". Changing the title of the section to "Interactions with humans and extinction" would also make sense, given as some of the discussion isn't really about humans at all. So I'd go for something like:

-Interactions with humans and extinction
--Pre-European contact
--18th century
--Later reported sightings
--Commercial value

(Also, if you have a source, it'd be great if you could open the aboriginal discussion by noting that information about contact with sea cows prior to Stellar's "discovery" is patchy.)

The aboriginals section is basically all speculation, but the European section is not really speculation at all, so it has more weight in my opinion. The global warming point just seemed relevant when discussing the St. Lawrence extirpation. I fixed the opening of the section   User:Dunkleosteus77 |push to talk  23:25, 15 July 2017 (UTC)[reply]

• "discovered in 1741". This is Eurocentric. Perhaps "first encountered by Europeans in 1741".
