Diprotodon

 * Nominator(s): Dunkleosteus77  (talk) 20:10, 15 January 2023 (UTC)

This article is about the largest marsupial ever, and the first Australian fossil mammal ever described, an elephantine wombat which lumbered across the continent until 40,000 years ago. This would be only the 3rd marsupial FA, after Tasmanian tiger and Tasmanian devil, and the 1st prehistoric marsupial Dunkleosteus77  (talk) 20:10, 15 January 2023 (UTC)

 * In 1830, bushman George Ranken – What does "bushman" mean here? Wiktionary tells me "A person who lives in the bush, especially a member of a community orfo ethnic group who lives in the bush". That would suggest to me that he was an Aboriginal Australian; is that the case?
 * The source uses the word "bushmen" prefacing George Ranken, but in a footnote it clarifies he got to Australia in 1821, so maybe "colonist"? Dunkleosteus77  (talk) 03:57, 3 February 2023 (UTC)

 * They were excavated – what is "they" referring to? The "fossil assemblage" is singular, so "It"?
 * done Dunkleosteus77  (talk) 03:57, 3 February 2023 (UTC)


 * there were no serious scientists in Australia – I fear that "serious" is judgemental and inappropriate. There was a "formal expedition" that excavated the remains, so on what basis can we claim these were not "serious" scientists? This is thin ice in my opinion.
 * The source says "...the lack of scientific expertise in the Australian community at the time..." and then introduces Owen. Maybe, "At the time these massive fossils were discovered, in the early years of colonial expansion, few minds were turned towards purely scientific careers"? Though this may be stretching the source Dunkleosteus77  (talk) 03:57, 3 February 2023 (UTC)
 * I would stick to the source as close as possible; maybe just "Australia lacked scientific expertise" or something similar. --Jens Lallensack (talk) 19:06, 3 February 2023 (UTC)

 * ; in their 1975 review of Australian fossil mammals – I suggest to start a new sentence here; the sentence is too long.
 * done Dunkleosteus77  (talk) 19:52, 11 February 2023 (UTC)


 * Also, adult Diprotodon specimens come in two distinct size ranges; … – this part seems to be a bit out-of-place. You discuss species, then size ranges, and then species again. Do species first, and then have a paragraph on the size ranges?
 * the size variation was one of the "subtle anatomical variations", they're all part of the same thought Dunkleosteus77  (talk) 19:52, 11 February 2023 (UTC)


 * Cladograms: On my screen the cladograms are one above the other, not left or right as indicated in the text.
 * yeah Wikipedia just made desktop view like mobile view, fixed Dunkleosteus77  (talk) 19:52, 11 February 2023 (UTC)


 * better adapted to the spreading dry and open landscapes – steep claim I would say: Can we argue that a species was poorly adapted to its environment? Where is that covered in the source?
 * it says diprotodontids are the most diverse group of vombatomorphs ever, and "While many vombatomorphian families... were extinct by early Miocene times, diprotodontids were one of the few to increase in diversity throughout the Cenozoic, appearing to benefit from the opening up of Australia's forests" Dunkleosteus77  (talk) 19:52, 11 February 2023 (UTC)


 * than other vombatiformes; and attained a – I think the ; needs to be removed or replaced with a comma
 * done Dunkleosteus77  (talk) 19:52, 11 February 2023 (UTC)


 * By the Late Miocene, diprotodontians became the most common marsupial order in fossil sites, a dominance which endures to the present day; at this point, the most prolific diprotodontians were diprotodontids and kangaroos. – I can't follow. How can a dominance in fossil sites endures to the present day (fossils do not form from one day to the next)? Is "at this point" referring to the "present day"?
 * diprotodontians are still the most abundant marsupial order Dunkleosteus77  (talk) 19:52, 11 February 2023 (UTC)


 * In 1977, Archer suggested that Diprotodon directly evolved from the smaller Euryzygoma, – Most of the "Evolution" section is not directly about Diprotodon but provides context. This sentence, however, might be the most important information that directly concerns Diprotodon of the whole section; yet I fear it gets a bit lost, being attached to a longer paragraph like this.


 * The Phylogeny section seems to miss an important information: What are the closest relatives of Diprotodon? Do scientists agree on the sister taxon or do different hypotheses exist? Were these closely related forms very similar in morphology and size to Diprotodon?
 * The only diprotodontid I see anyone trying in some way to relate to Diprotodon is Euryzygoma mentioned in Evolution, but you can see in the Beck 2020 cladogram that they decided not to group them as sister taxa with no explanation, so I'm not sure what to do here. It's probably because the diprotodontid fossil record is pretty fragmentary Dunkleosteus77  (talk) 19:52, 11 February 2023 (UTC)


 * The description is easy to follow and accessible. However, it only compares Diprotodon with modern marsupials, but does not stay how to distinguish it from its closest relatives. What were the diagnostic features? If you think this is too technical, consider adding just a sentence to the "Phylogeny" section giving some examples to provide an idea how paleontologist diagnose this taxon.
 * Owen didn't specifically give a list of diagnostic features as he was describing the entire skeleton, he just started going off with comparisons (which I guess is kinda the same thing). Price seems to give a lengthy description of the topography of each tooth, which I guess would also be diagnostics, but I think far too specific Dunkleosteus77  (talk) 19:52, 11 February 2023 (UTC)


 * than Murray's guesstimate – again, I think "guesstimate" is judgmental and has to be avoided. Just say "estimate". Instead of writing "more analytical approach", I would go for "more sophisticated approach".
 * done Dunkleosteus77  (talk) 19:52, 11 February 2023 (UTC)


 * Using Burness's methods, Diprotodon is 25% larger than expected – expected by whom? Murray's estimate? If so, write "than previously assumed"? --Jens Lallensack (talk) 16:52, 31 January 2023 (UTC)
 * No, but it's not important enough actually to explain it, so I just removed it Dunkleosteus77  (talk) 19:52, 11 February 2023 (UTC)


 * I'll try to get to these comments over the weekend Dunkleosteus77  (talk) 00:54, 3 February 2023 (UTC)


 * Adult Diprotodon skeletons can measure 160–180 cm (5 ft 3 in – 5 ft 11 in) at the shoulders, and 275–340 cm (9–11 ft) from head to tail. – this is slightly mis-representing the source, which is clearly about size in life, not the size of mounted skeletons.
 * done Dunkleosteus77  (talk) 19:52, 11 February 2023 (UTC)


 * Still, the low seasonal δ13C values (its carbon isotope ratio remained about the same in both winter and summer, so it ate the same proportion of C3 and C4 plants regardless of their seasonal abundance) indicate that Diprotodon was a selective eater, at least more so than the modern wombat. – I think this needs clarification and has several issues. First, where is "its" referring to, to the delta-13-C? If so, how can it be both "low seasonal" and "about the same in both winter and summer"? And why does this indicate it was a selective feeder? Lastly, the addition in the brackets is better placed in a separate sentence; this sentence is too long and confusing as is.
 * fixed Dunkleosteus77  (talk) 19:52, 11 February 2023 (UTC)


 * These fossilised herds – this does not seem to be covered by the sources? Diprotodon graveyards could have accumulated over time (therefore comprising members of multiple herds). A single herd (as implied in "fossilised herds") can only be demonstrated when there is exceptional evidence; does such evidence exist?
 * In a few places, the source says things like "As the [Bacchus Marsh] assemblage is thought to represent individuals trapped in muds of a drying marsh, it is possible that a single herd was sampled" Dunkleosteus77  (talk) 19:52, 11 February 2023 (UTC)

 * "In 1838, while studying a piece of a right mandible with an incisor, Owen compared the tooth to that of a wombat and a hippo, and designated it as the new genus Diprotodon". You can change the next line to say that when Mitchell was told, he included it in the journal

 * "the one time": once?
 * I prefer "the one time" so it's clear it's talking about the aforementioned usage, otherwise it sounds like an introduction Dunkleosteus77  (talk) 20:53, 24 February 2023 (UTC)


 * You have "Darling Downs" and "the Darling Downs": is the definite article needed?
 * Where is the definite article not used? Dunkleosteus77  (talk) 20:53, 24 February 2023 (UTC)


 * "rather complete": rather complete? Are they complete or nearly complete?
 * What's wrong with the word "rather"? I've used it as a descriptor many times without problems, like Ambulocetus, Solo Man, Homo antecessor, etc. Dunkleosteus77  (talk) 20:53, 24 February 2023 (UTC)


 * "in dry lake- or riverbeds" Looks (and reads) a little oddly. "in the beds of dried up lakes or rivers" may be better
 * "lake- or riverbed" is a perfectly valid phrase Dunkleosteus77  (talk) 20:53, 24 February 2023 (UTC)


 * "a sheep property just east": again, a little odd. "a sheep property to the east"?
 * that works too Dunkleosteus77  (talk) 20:53, 24 February 2023 (UTC)


 * "Diprotodon individuals over a few acres, and more were uncovered": this sentence covers 80 years and is a bit surprising (we were looking at Hurst's activities at the beginning!). Maybe a full stop after acres and continue from "More were uncovered..."

 * "Multiple herds of these animals at different times probably got stuck in the mud during their crossing while the water was low during dry seasons". Again this is a bit bumpy to read through and if we're reporting something in WP's voice, "probably" shouldn't be included. Hypotheticals should always be attributed. Possible rewording could look something like "Bloggs considers it likely that several herds of Diprotodon crossed the (river or lake) while the water was low during dry season and became stuck in the mud"
 * You can't use definitive wording in these kinds of matters, because it's not like we have witnesses to the event. And, if I do "Bloggs says xyz" then it sounds like Bloggs came up with the idea and he's the only one really saying it Dunkleosteus77  (talk) 20:53, 24 February 2023 (UTC)
 * This is a problem (still). Naming someone who has said something doesn’t mean they were the first. _ SchroCat (talk) 22:35, 24 February 2023 (UTC)
 * I found the first guy who said it, so attributed Dunkleosteus77  (talk) 23:29, 25 February 2023 (UTC)


 * "several other species were erected": erected? Identified, maybe? If this is technical use it fails WP:JARGON, if it isn't, then it's not in the OED!
 * It's not jargon and it's never been an issue before, and I wouldn't use the word identify because it sounds like a real and valid discovery, which clearly it wasn't because the names are no longer used Dunkleosteus77  (talk) 20:53, 24 February 2023 (UTC)

 * "Also, adult Diprotodon specimens": never start a sentence with "Also" on WP – it just looks like something that's been forgotten and added in later. The sentence and the one that follows seem to be unconnected to the opening sentence of the paragraph and the final one. (ie, you mention the other species, then talk about the differing/non-differing sizes, then move onto the other species again. It's a bit of a confusing paragraph – at least for a non-specialist like me.

 * "Australian palaeontologists": aside from repeating Australia from three words previously, their nationality is unimportant as far as this article goes. Just "Palaeontologists" will suffice
 * Including nationality when introducing a person is pretty standard (or at least commonplace) on the paleo side of Wiki, such as in Oxalaia, Cimoliopterus, Paranthodon, etc. Dunkleosteus77  (talk) 20:53, 24 February 2023 (UTC)
 * Nationality isn’t important: the names and findings are. - SchroCat (talk) 22:35, 24 February 2023 (UTC)
 * Personally I like reading the nationality to see how multinational (or not) research on the subject is, and it's a harmless, unobtrusive addition Dunkleosteus77  (talk) 23:29, 25 February 2023 (UTC)
 * I, as a reader, don’t feel it’s unobtrusive. The constant repetition of nationality makes me wonder if there is a reason: are American palaeontologists better or worse at some aspects than French or Australian ones? Do British or German ones have an advantage or disadvantage? There are about fourteen references before the family tree: for the general reader this looks like the nationality actually matters somehow ... but it really doesn’t. It’s a distraction that doesn’t add anything for the general (or specialist) reader. - SchroCat (talk) 23:14, 1 March 2023 (UTC)
 * It's more like scientists from these places seem to be taking more of an interest in this topic, you're reading way too far into this if you think the average reader is interpreting the small mention of nationality as racist or whatever it is you're implying Dunkleosteus77  (talk) 01:27, 3 March 2023 (UTC)
 * No, I’m not implying anything of the sort. I have given the reasons quite clearly. - SchroCat (talk) 06:00, 3 March 2023 (UTC)


 * Bullet list: "erected", as before; nationalities, as before
 * "Australian palaeontologist Gilbert": nationality as before

Done to the end of Research history. I have concerns on the text with this article and we're only at the end of the first section. It's a bit bumpy to read through – not just the scientific information, which often causes problems in flowing prose, but in the history and description, where I keep tripping over awkward constructions and odd phrasing or word choice. – SchroCat (talk) 15:42, 21 February 2023 (UTC)

I've gone through one of the lower sections and see other problems in the prose which I think should be cleared up before coming to FAC. I'm reluctantly going to oppose this (something I dislike doing), but my recommendation is that you withdraw this nom and go through PR to get the prose issues sorted before returning. - SchroCat (talk) 17:33, 22 February 2023 (UTC)
 * Most of your comments are purely stylistic so I ask you to reconsider Dunkleosteus77  (talk) 20:53, 24 February 2023 (UTC)
 * No, these are not stylistic, and neither are many of my other concerns. Saying that something passed elsewhere isn’t a defence. Neither is claiming these are ‘just’ stylistic. Just glancing down the page the following caught my eye “They [the sinuses] may have also helped dissipate stresses produced by biting more efficiently across the skull”: reading literally, this is saying by the efficient way the sinuses bit across the skull, they dissipated stress. There are several such points where a reader will both trip up on and be confused by the prose. You don’t have to take my comments or my oppose on board (these are just my opinion, after all), but I’m not inclined to withdraw the oppose. - SchroCat (talk) 22:14, 24 February 2023 (UTC)
 * Just clarifying, my oppose isn’t on stylistic grounds, but on FAC criteria 1.a: “well-written: its prose is engaging and of a professional standard”. - SchroCat (talk) 23:21, 1 March 2023 (UTC)
 * Would it help sending it to the WP:league of copy editors? FunkMonk (talk) 12:11, 6 March 2023 (UTC)
 * It might, but this has been open a long time and, as Gog noted earlier, is still not approaching consensus to promote. I'm afraid it's time to archive this and work on improvements outside the FAC process. A visit to PR before another try here also seems worthwhile. Cheers, Ian Rose (talk) 12:38, 6 March 2023 (UTC)
