Paleocene

 * Nominator(s):  User:Dunkleosteus77 &#124;push to talk 16:11, 12 October 2019 (UTC)

This article is about the 10 million year period after the dinosaurs went extinct. There're no other GA or FA geological periods so I'm trying to make a really good template for it  User:Dunkleosteus77 &#124;push to talk 16:11, 12 October 2019 (UTC)

 * I'll have a look soon. There are a bunch of duplinks you can highlight wwith this script: FunkMonk (talk) 08:40, 16 October 2019 (UTC)

 * Not all people mentioned are presented with both nationality and occupation.
 * If you're referencing T. C. R. Pulvertaft, I originally put "Danish geologist" but this got reverted because the source didn't say he's Danish  User:Dunkleosteus77 &#124;push to talk 21:45, 17 October 2019 (UTC)


 * I think you could expand the etymology section a bit more with history of the term., For example, you don't mention that it is an epoch, when it was considered as such, how use of the term has evolved, and what the Tertiary is, or what period it is currently considered part of. Perhaps the etymology section could be expanded into a history of usage section or similar.
 * I think all that's really relevant here about the Tertiary and Paleogene is that they're periods which contains the Paleocene. Discussion over their nomenclature and dates and so forth can be discussed in their respective articles  User:Dunkleosteus77 &#124;push to talk 21:45, 17 October 2019 (UTC)
 * What I said mainly concerned the history of the concept Paleocene, "when it was considered as such (an epoch), how use of the term has evolved". You cover the usage of the stages within it in more detail, so I don't see why you shouldn't for the overall subject itself. FunkMonk (talk) 11:11, 19 October 2019 (UTC)
 * How's it now?  User:Dunkleosteus77 &#124;push to talk 17:26, 20 October 2019 (UTC)
 * I think the context is good, maybe a bit long-winded. FunkMonk (talk) 14:18, 21 October 2019 (UTC)
 * Did you want specific parts trimmed off?  User:Dunkleosteus77 &#124;push to talk 18:26, 1 November 2019 (UTC)


 * Similarly, "first epoch of the Paleogene Period in the modern Cenozoic Era" is only mention in the intro, but should be covered and explained further in the article body, perhaps in the Boundaries section or a "usage/history" section.

 * I wonder if there is any logic as to when you use a fossil or a life restoration to represent an animal?

 * "The sea cliffs of Itzurun beach near the town of Zumaia" This caption gives no context as to why the image is used here. Also, you could mention the country.
 * That would be a very long caption if it did, which is why it's located right next to the paragraph which gives it context  User:Dunkleosteus77 &#124;push to talk 21:45, 17 October 2019 (UTC)
 * At the very least you should mention the formation it represents. Image captions are supposed to provide context for the images, see Manual of Style/Captions: "3 establishes the picture's relevance to the article; 4 provides context for the picture;". Neither has been done here. FunkMonk (talk) 11:11, 19 October 2019 (UTC)
 * added "the GSSP for the Selandian and Thanetian"  User:Dunkleosteus77 &#124;push to talk 15:37, 20 October 2019 (UTC)


 * The K–Pg boundary rock image could also be given a location, which I think would actually be good for all the fossil and rock images used, for context. Age or formation as well.

 * "In stratigraphy, a stage is a distinct rock stratum" You could likewise explain what an epoch and period are, when you put the Paleocene into context as discussed above.
 * "and is marked by the first appearance of Discoaster and a diversification of Heliolithus" State what kind of lifeforms these are, also elsewhere in the article when you mention taxa.

 * "Today, deep water formation–where, in the thermohaline circulation, warm tropical water becomes colder and saltier at the poles and sinks (downwelling)–occurs in two places: the North Atlantic and the Southern Ocean near the Antarctic Peninsula." This is an extremely long and convoluted sentence, perhaps places like this need parenthesis instead of subordinate clauses.

 * "probably to take advantage of the newly evolving birds and mammals for seed dispersal,[82] fill recently emptied niches, and an increase in rainfall" Something missing here, I guess "take advantage of" also applies to the increased rainfall, but not to "fill empty niches". One solution could be to reorder it as "to take advantage of the newly evolving birds and mammals for seed dispersal,[82] an increase in rainfall, and to fill recently emptied niches".

 * "Sea life" Why exclude rivers and lakes? Better to make the section inclusive, otherwise you don't have anywhere to cover freshwater animals. Even better, you should divide it into fishes, which it mainly covers, and aquatic invertebrates, as all the other sections are grouped by taxon, not by habitat.

 * "Conversely, sharks and rays appear to have been unable to exploit the vacant niches, and recovered the same pre-extinction abundance." This is unclear due to the tense. Did they or did they not recover their former abundance?

 * Ok, then the sentence is a bit hard to understand. You first say they were unable to exploit vacant niches, but that they recovered the same abundance as before. So what is meant by abundance, numbers? Because the former part of the sentence would seem to preclude diversity? FunkMonk (talk) 10:38, 26 October 2019 (UTC)
 * It says, "sharks appear to have remained stuck at similar abundances in the Paleocene as they had in the Cretaceous, suggesting that they were unable to exploit newly opened niches after the extinction," also I really don't understand what the confusing part is <span style="font-family:Monotype Corsiva;background:#E6E6FA;border:solid 1px;border-radius:7px;box-shadow:darkblue 0px 3px 3px;"> User:Dunkleosteus77 &#124;push to talk 15:42, 30 October 2019 (UTC)
 * The word "recovered" suggests that there was a drop in abundance at some point, not that it remained steady. FunkMonk (talk) 22:32, 30 October 2019 (UTC)
 * Yeah, a drop in abundance because of the K-T extinction event, which recovered in the Paleocene <span style="font-family:Monotype Corsiva;background:#E6E6FA;border:solid 1px;border-radius:7px;box-shadow:darkblue 0px 3px 3px;"> User:Dunkleosteus77 &#124;push to talk 18:26, 1 November 2019 (UTC)
 * Then it is the juxtaposition of the information that is confusing. Perhaps ""Conversely, sharks and rays appear to have been unable to exploit the vacant niches, yet/but recovered the same pre-extinction abundance" would make it less ambiguous. FunkMonk (talk) 22:16, 4 November 2019 (UTC)
 * No, it's the fact that they had recovered the same abundance level which indicates they didn't exploit vacant niches. If they had recovered greater abundance, this would indicate they did exploit vacant niches. If they had recovered less abundance, this would indicate they were outcompeted in the Paleocene <span style="font-family:Monotype Corsiva;background:#E6E6FA;border:solid 1px;border-radius:7px;box-shadow:darkblue 0px 3px 3px;"> User:Dunkleosteus77 &#124;push to talk 01:27, 5 November 2019 (UTC)

 * "The only known Paleocene ant fossil is the aneuretine Napakimyrma paskapooensis from the 62–56 million year old Paskapoo Formation.[1" This should be stated in the beginning of the ant paragraph then, after "Though there is a gap in the ant fossil record from 78–55 mya".

"The first placentals and marsupials evolved in the Paleocene." and (from Cenozoic) "Modern placental mammals originated d uring this time" and even more interestingly "...though there was an explosive diversification, the affinities of most Paleocene mammals is unknown, and only primates, carnivorans, and rodents have unambiguous Paleocene origins, resulting in a 10 million year gap in the fossil record of other mammalian crown orders" Take all together, I think there should be something in the WP:LEAD about placental mammals, primates, carnivorans, and rodents.All four, not just the first... ♦ Lingzhi2 (talk) 12:07, 17 October 2019 (UTC)

 * Your idea of what goes in a lead and mine seem to be radically different. I think the bit about placental mammals, primates etc. is a key point. After all, " primates are us". If you keep it so general that you exclude such a monumental development, the lead loses its value altogether. ♦ Lingzhi2 (talk) 21:59, 17 October 2019 (UTC)
 * "Primates" didn't evolve until the absolute beginning of the Eocene. Any primate-like creature in the Paleocene is arbitrarily thrown into Plesiadapiforms (the ancestral group), so the roots of Primates was in fact in the Paleocene, but primate Primates didn't come in until the Eocene.

 * "Since the mid-Maastrichtian, more and more carbon had been sequestered in the deep sea, leading to a trend in increasing deep sea temperatures." How does increasing carbon in the deep sea increase temperatures there? I understand how carbon in the atmosphere increases global temperatures via the greenhouse effect, and I could see that increased levels of carbon in the deep sea could be an indicator of increased carbon in the atmosphere.  Ϣere Spiel  Chequers  10:09, 24 October 2019 (UTC)
 * the source says "the rise in δ13C and deep water temperatures probably reflect carbon burial and CO2 sequestration". I think the source is trying to say δ13C increased concentration because total ocean volume decreased, which caused increased give-off of oceanic carbon to the atmosphere, which increased surface temperatures, which in turn increased ocean temperatures, and warmer water has a reduced capacity to store carbon, which eventually led to the Dan-C2 Event <span style="font-family:Monotype Corsiva;background:#E6E6FA;border:solid 1px;border-radius:7px;box-shadow:darkblue 0px 3px 3px;"> User:Dunkleosteus77 &#124;push to talk 16:42, 24 October 2019 (UTC)
 * I doubt total ocean volume is the issue, if anything that shrinks as oceans cool and as glaciation locks up water. Rising temperatures and ice free poles should increase ocean volume. Do you have another source available for this bit?  Ϣere Spiel  Chequers  17:45, 24 October 2019 (UTC)
 * There was no ice at the poles from the beginning of the Mesozoic to the late Eocene (so increasing temperatures wouldn't add water to the oceans). The total volume of the oceans was shrinking due to tectonic movement causing the retreat of inland seas (such as the Western Interior Seaway), causing ocean carbon to become more concentrated. He cites someone else who doesn't go farther than "carbon feedback loop" (but he doesn't explain what that means) <span style="font-family:Monotype Corsiva;background:#E6E6FA;border:solid 1px;border-radius:7px;box-shadow:darkblue 0px 3px 3px;"> User:Dunkleosteus77 &#124;push to talk 15:03, 25 October 2019 (UTC)
 * Water expands slightly when heated, so even after all ice has melted, inut creasing temperatures will slightly increase the volume of the Oceans due to thermal expansion. Tectonic movement won't change the total volume of the ocean, but it can move things around - so if the Western interior seaway is being uplifted and drained, that water goes elsewhere.  Ϣere Spiel  Chequers  10:23, 5 November 2019 (UTC)
 * Okay, so I think I'm understanding this now. The source (Quillévéré) says "The Dan-C2 event is preceded by a long-term rise inglobal δ13C of marine carbonates and deep water tem-peratures starting during the mid-Maastrichtian (e.g. Norris et al., 2001). As pointed out by Zachos et al.(1989) and Stott and Kennett (1990), the rise in δ13C and deep water temperatures probably reflect carbon burial and CO2 sequestration" and Stott doesn't say anything more than "carbon feedback loop", and Zachos's main point is that carbon deposition in the deep sea stopped (Strangelove ocean) at the K-T boundary, but there was a cooling trend right before which led to increased carbon deposition, and the source Zachos is citing says the Strangelove ocean increased atmospheric CO2 in the early Danian because the surface of the ocean couldn't absorb as much carbon, which increased surface temperatures, and (he doesn't explicitly say this next part) we know deep sea temperatures fluctuate with surface temperatures, and warmer water dissolves less carbon (the closest Quillévéré says to this is the PETM was caused by the "thermal liberation" of methane), leading to exhumation. This may be what Stott was getting at with "carbon feedback loop" because he also cites Zachos.

 * However, the largest known Mesozoic mammal, Repenomamus robustus, which reached about 1 m (3 ft 3 in) in length and 12–14 kg (26–31 lb) in weight–comparable to the modern day Virginia opossum–may have operated on the same trophic level as some small dinosaurs. – I would greatly shorten here, as it seems a bit off-topic. Also, the trophic level depends on if you are a herbivore or carnivore; both dinosaurs and Mesozoic mammals were both depending on the species, so this does not make so much sense in my opinion.

 * and dental complexity correlates to a broader range in diet – I doubt that this is the case, I expect the opposite. What the paper you are citing says is "disparity of dental complexity", which is quite a different thing. "Disparity" means morphological variability; it means that if there are species with simple dentition and species with complex dentition in a group, the range in diet will be greater.

 * Their extinction allowed flying birds to attain greater size, such as pelagornithids and pelecaniformes. However, the Paleocene pelagornithid Protodontopteryx was quite small compared to later members, with a wingspan of about 1 m (3.3 ft), comparable to a gull. – Last sentence contradicts your first statement, it is unclear what the point is. Why not give an example of one of greater size (as indicated by the first sentence), or isn't there any?
 * A lot of the large ones are known from the absolute beginning of the Eocene, which means that they evolved in the Paleocene, but the Paleocene bird fossil record isn't very expansive.

 * You are giving a lot of size estimates, focusing on the largest of the clades. It makes sense when the significance of body size is also discussed (e.g., for the recovery after the mass extinction), and this is what you often do, so I would say that is ok. But I wonder what the relevance of the size estimates is for the crocodilians you give.

 * Thanks for the corrections so far (you could, in general, save some reviewer time by considering comments a bit more carefully; e.g., zombie taxa is indeed not correctly linked). The article has shaped up nicely. I wonder, however, if the article is complete already. It certainly has balance issues still (as mentioned, loads on oceanography but geologic events are, if at all, only briefly mentioned). Thinking about it, I would argue that sedimentology is missing completely. What are the major sedimentary basins at the time? I would also mention the most important fossil lagerstätten (also do not forget about amber). Any meteor craters that formed during that time? Another thing that is missing completely are resources such as oil and coal that formed during the time. Yes, sounds boring at first, but also tells a lot about the environment at the time (coal swamps etc.). I see quite some possibilities for expansion. --Jens Lallensack (talk) 17:07, 3 November 2019 (UTC)
 * Important formations are kind of interspersed throughout the article (like Castle Rock) but I guess there're more I should add, so I'll get to that, but I did overlook meteor craters and minerals, so I'll be working on a new section <span style="font-family:Monotype Corsiva;background:#E6E6FA;border:solid 1px;border-radius:7px;box-shadow:darkblue 0px 3px 3px;"> User:Dunkleosteus77 &#124;push to talk 21:33, 3 November 2019 (UTC)

 * Maybe put the "Stratigraphy" section into chronological order? I mean, discussing the history of the Selandian and Thanetian before discussing the Itzurun section? The whole section jumps quite a bit (e.g., back to Itzurun in the last paragraph; the reader might have already forgotten what Itzurun is at this point).
 * It is in order, it's just kinda weird because the modern GSSP for the Selandian and Thanetian are both Itzurun, so it goes: Paleocene → history of Danian/Danian → Selandian/Thanetian → history of Selandian → history of Thanetian. It should say what the GSSP for the Selandian and Thanetian is today before going off about their histories to avoid confusion and provide context without too much repetition, and further discussion about Itzurun needs to be paired with the former. It was more straightforward with the Danian because all the relevant information could fit neatly into a single paragraph, so we can immediately move from "this is how it was, and this is why it's something else now". I was debating how to do this exactly, and I figured this was the best way to avoid "this it how it was; for details how it is now, see below" <span style="font-family:Monotype Corsiva;background:#E6E6FA;border:solid 1px;border-radius:7px;box-shadow:darkblue 0px 3px 3px;"> User:Dunkleosteus77 &#124;push to talk 04:32, 13 November 2019 (UTC)

 * "In the Paleocene, the continents continued moving towards their present positions." This reads as if you are in the middle of an exposition which has already explained the continents' positions in the Cretaceous and their movements. It needs re-writing. I suggest starting with the position of the continents 66 million years ago as at North America, Eurasia and Africa connected, as were South America, Antarctica and Australia. India was moving towards Asia. I doubt whether you need to mention the Rockies and certainly not joining of the Americas which only occurred 3 million years ago.
 * When the Americas joined is not common knowledge, and the uplift of a major mountain range is definitely important <span style="font-family:Monotype Corsiva;background:#E6E6FA;border:solid 1px;border-radius:7px;box-shadow:darkblue 0px 3px 3px;"> User:Dunkleosteus77 &#124;push to talk 17:07, 12 November 2019 (UTC)


 * "The extinction event caused a floral and faunal turnover of species, with previously abundant species being replaced by previously uncommon ones. With a global average temperature of about 24–25 °C (75–77 °F), compared to 14 °C (57 °F) in more recent times, the Earth had a greenhouse climate without permanent ice sheets at the poles." This is confusing as the first sentence is about the immediate effects of the extinction, and the second sentence reads as if it is still about the effects but is presumably about the long term climate of the Paleocene. The comparison with temperatures today is misleading as it implies that the period was unusually hot, whereas we are living in the Late Cenozoic Ice Age, which started about 34 million years ago. Having no ice at the poles and much higher sea levels is the normal state of the earth, although it would be catastrophic for us. I do not know whether the Paleocene was hotter than average, but you would need to compare with the long term average over the history of the earth.
 * The earth shifts from greenhouse climate to icehouse climate. The Cambrian to mid-Carboniferous was a greenhouse, the late-Carboniferous to the Permian was an icehouse, the Triassic to Early Eocene was a greenhouse, and then from then to present is an icehouse (that's why it says "Earth had a greenhouse climate") <span style="font-family:Monotype Corsiva;background:#E6E6FA;border:solid 1px;border-radius:7px;box-shadow:darkblue 0px 3px 3px;"> User:Dunkleosteus77 &#124;push to talk 17:07, 12 November 2019 (UTC)
 * The earth shifts in climate, but less than 100 million out of 540 million years of the Phanerozoic eon was icehouse. Most readers will think that saying that the Paleocene had a greenhouse climate means that it was unusully hot, and I think that it is important to explain that this is not correct.

"a mass extinction of 30–50% of benthic foraminifera–planktonic species which are used as bioindicators of the health of a marine ecosystem–the largest in the last 90 million years". This implies that the PETM and Cenomanian-Turonian boundary event foraminiferal extinctions were both greater than at the K-Pg. I think you need better authority for this than a (presumably) non-peer reviewed book chapter. See for example.
