message: Is it possible that Deinocheirius is a dryptosaur? Like Appalachiosaurus and Dryptosaurus. I haven't seen a good picture of the original bones, but I have seen a model skeleton of a dryptosaur, and the arms are really long  —Preceding unsigned comment added by Metalraptor (talk • contribs) 23:52, 25 March 2008 (UTC)
replies: text: Haven't seen that proposed before. Dryptosaurids are generally thought to be primitive tyrannosaurs. The arms of Deinocheirus closely resemble ornithomimids (equal-length fingers, etc.), though it's also been proposed that they were related to therizinosaurs.

thread_title: Dryptosaur

message: Major theories:
*Claws were used to slash termite nests (Similar to modern Anteaters today) (Meaning it was an inscectivore)
*Claws were used to strip leaves off trees (Similar to the extinct Ground sloths) (Meaning it was a herbivore)
*Maybe all of the above (Meaning it was an omnivore)
*Claws were for defense
*Claws were used to slash prey or SLAY (Not very supported) (Meaning it was a carnivore)
*Maybe all of the above (DEFINITLY a omnivore)

message: I think it look more like Therizinosaur than ornithomimosaurian...  — Preceding unsigned comment added by Bella7790 (talk • contribs) 09:43, 21 March 2013 (UTC)
replies: text: Therizinosaur claws are usually a lot longer. FunkMonk (talk) 12:14, 21 March 2013 (UTC)

text: Unlikely, the arms resemble maniraptors more then a compsognathid, not to mention members of the Compsognathidae are last seen in the Early Cretaceous (more precisely, 108 mya), while Deinocheirus only appeared 70 mya, so unless there's a large ghost lineage of compsognathids that become ornithomimosaurian in arm design, it's more likely Deinocheirus is a ornithomimosaur then giant compsognathid. Though Funky, I would note not all therizinosaur claws are Therizinosaurus-proportion. Remember Nanshiungosaurus? --Raptormimus456 (talk) 18:47, 30 May 2013 (UTC)

replies: text: Deinocheiridae looks to be valid (as a grouping of Deinocheirus, Beishanlong and Garudimimus, from the new material seen at SVP 2013).

message: The article mentions that "both forelimbs excluding the right claws" were found in the holotype specimen, but the photos make it look like the *left* claws are missing. Is that right? Oconnor663 (talk) 21:57, 3 August 2014 (UTC)
replies: text: The describing article indicates the right claws as missing. The left claws were not found articulated, so it's possible that they were later re-identified. Alternatively, a mistake was made when the pictured mount was made :o).--MWAK (talk) 18:13, 22 October 2014 (UTC)

message: The article coining Deinocheirus (and Deinocheiridae) is marked as having been published in 1969 both on its own pages and on the journal website. However, the publication is currently marked here (and on many other websites) as 1970. What is the case? Albertonykus (talk) 16:40, 7 November 2014 (UTC)
replies: text: Well, it is usual to indicate the actual date of publication, i.e. when the magazine was distributed. This also determines priority. Often the "issue" of a certain month is only printed and posted many months later. Apparently, in this case it took place in 1970. At the time it was clear to all what the correct date was and it has been traditioned ever since. There are many such cases.--MWAK (talk) 20:14, 24 December 2014 (UTC)

thread_title:  Orphaned references in [[:Deinocheirus]] 

message: , since this talk page is so short, we can probably talk about FAC stuff here anyway, and everyone is of course welcome to chime in. First iffy thing I noticed (apart from all the obviously outdated stuff, which means everything has to be rewritten) is that some sections, mainly description, go too much into issues that should be relegated to the history section. Stuff about how and when something was discovered does not belong there, description should simply be a description of the animal. I think I'll write what I can find about the skull, just to set the tone. Then there's the issue of taxobox image. I personally like the current one, since it's the holotype, which gave it its name, but the hands seem to be mounted inaccurately. Some mounted casts look better in that regard, but the photos just don't look so good. Also, thanks to  for the updated size comparison! FunkMonk (talk) 18:41, 25 November 2014 (UTC)
replies: text: I think the initial paper should be enough to get a non-technical description done. Fine details of the skull bones and comparative anatomy wouldn't really go in a popular encyclopedia article anyway. Stating that the head is toothless with a long snout, flat beak, and robust lower jaw, for example, should be enough for our purposes. Dinoguy2 (talk) 23:07, 25 November 2014 (UTC)
replies: text: Alright. On that note, in this podcast, Darren Naish mentioned undescribed material that will make Deinocheirus even weirder. Anyone have an inkling of what this could be? FunkMonk (talk) 11:58, 26 November 2014 (UTC)
replies: text: May have been the upcoming study on its brain size and structure that was presented at SVP. Albertonykus (talk) 22:01, 26 November 2014 (UTC)
replies: text: Alright, then it probably won't change too much. By the way, seems several others are editing, anyone interesting in joining the group effort? There is no limit for number of FAC nominators. FunkMonk (talk) 13:22, 28 November 2014 (UTC)
replies: text: I'm in. Read the abstract, and it would not change any info, just provide a little more to the paleobiology section. IJReid (talk) 15:04, 28 November 2014 (UTC)
replies: text: Heh, I knew! And if those abstracts are available on the net, I'd say they count as published... Not peer reviewed yet, but probably won't change much by then. FunkMonk (talk) 16:52, 28 November 2014 (UTC)

text: Yeah. Are we going directly for FA, or will we nominate for GA first? I will try to start some minor copyediting in the anatomical information. I don't think there is much more from the 2014 description apart from the description of vertebrae, which I think is too technical to summarize efficiently, and isn't that interesting. Btw, there are applications for access to ScienceDirect through the Wiki Library, might be interesting. IJReid (talk) 00:02, 21 December 2014 (UTC)
replies: text: Hmm, I think that would be quite a bit immature. There is more in the sources we can add, and the structure of the text itself is still just slapped together (I haven't done much work yet, but will soon, when I get myself together). And it definitely needs a GAN first. We need to summarise all relevant info from the various sources. A lot of it needs rewriting and trimming asd well, and the lead is incomplete. My Christmas vacation just began, so I'll do some polish the upcoming days... Anatomical details are fine, as long as they are explained well, see Nigersaurus and Paraceratherium. Older dinosaur FAs seem to have very light descriptions, but the newer ones with more detail have been accepted as well during FAC. FunkMonk (talk) 00:13, 21 December 2014 (UTC)

text: Hmm. I'm using Canadian English. They're quite similar, so I don't think there will be an issue. IJReid (talk) 03:53, 25 December 2014 (UTC)
replies: text: Alright, and nice fixes! When the issue below is fixed, I'll go through the rest of the article, and it'll probably be ready for GAN some time next week. I'll list it for copy edit before that, as it's always a long wait... FunkMonk (talk) 21:02, 25 December 2014 (UTC)

text: Yes, I overreacted. There are two mechanisms. In the standard one, in fact the usual cable bridge metaphor, the hindlimbs are the equivalent of a single pillar, extended to above by the "hump". From this pillar torso and tail are suspended by means of a complex ligament and muscle system. The weight of the abdomen pulls the vertebral column downwards, curving it. Therefore the vertical neural spines on top of the vertebrae fan out. This is counteracted by ligaments between those spines. The longer the spines, the stronger the ligaments, the better supported the abdomen. But Deinocheirus shows a possible second mechanism: perhaps transverse ligaments from the sides of the spines supported the ribs or perhaps even directly the abdomen. In that case each neural spine is the equivalent of a pillar. The second mechanism should be mentioned, of course. In view of the possible confusion between the two mechanism, I feel it is best to discard the, probably not very insightful, "cable bridge" metaphor entirely and simply explain what happens in both cases. The suggestion that the hindlimbs would be suspended (the Pinocchio model) should, charitably, be ignored :o) (I know, it might work through elastic energy).--MWAK (talk) 09:35, 26 December 2014 (UTC)
replies: text: Fine with me, do you think you could come up with and add a text that is based a bit more on the wording in the paper? Then I guess it would be ok, because it is allowed to "translate" scientific language for the layreader. FunkMonk (talk) 14:47, 26 December 2014 (UTC)
replies: text: Can't be too difficult. I just keep it very general :o).--MWAK (talk) 18:11, 26 December 2014 (UTC)

text: I just found a photograph of the forelimbs in excavation, but I'm not certain if it can be uploaded. On the last page of the narrative of the expeditions  there is a photograph of the forelimbs in situ. Would these be uploadable under a cc license, or not? IJReid (talk) 18:14, 26 December 2014 (UTC)
replies: text: As far as I know, that journal isn't free, you may be thinking of Acta Polonica etc... FunkMonk (talk) 00:08, 27 December 2014 (UTC)

text: I added back the other photo of the holotype arms, since well, it's the holotype (which alone gives it more reason to be in the history section than any cast), it is a good photo with a human for scale, and it has also been used outside Wikipedia. The many images of the arm casts can be replaced over time, as we will hopefully get photos of other elements. Also, I removed some stuff not mentioned in the papers. Where does it specifically say anything about new terminology? And note that it does not use either the words sail or hump. Holtz mentions a "sail" once, so we can use that. FunkMonk (talk) 00:34, 29 December 2014 (UTC)
replies: text: Some more ref issues: journal article titles should not be capitalised, only book titles. And why where the cite DOI templates removed? They make it much easier to edit refs. The lead needs expansion, but that should be done when the article itself is written. And , the Dutch article states the element under the skull here is a neural spine, is that correct? Doesn't appear symmetrical? I'm hoping for a GAN by the end of this week, but may not be ready by then. FunkMonk (talk) 03:00, 29 December 2014 (UTC)
replies: text: You're too clever by half, Funkmonk ;o). Indeed it's not a spine but a skull. Next good question: what skull?--MWAK (talk) 07:39, 29 December 2014 (UTC)
replies: text: Seems to be a Gallimimus skull. Based on the skull measurement in the article, the smaller skull would be around 640 mm long, which is would give the animal a length of about ~7m the only ornithomimosaurians to reach 7m are Beishanlong, which is known from no skull, and Gallimimus, which is known from many specimens including skulls. IJReid (talk) 15:44, 29 December 2014 (UTC)
replies: text: That was my first thought too when I saw the picture: they put a Gallimimus skull in front of it for comparison. But that can't be true: e.g. the Gallimimus holotype, from an individual estimated by Mortimer at six metres length, has a skull only thirty-three centimetres long! Also the morphology is very different. A Gallimimus skull has a concave top profile and a pointed snout, not overly flattened. But the skull shown has clearly a convex profile and a flat, wide, snout. It looks like nothing so much as a juvenile Deinocheirus. Then I thought: "Nah, that can't be true. Surely they would have made that public. It must be some deformed spine, with the neural channel giving the false impression of eye sockets". But on second thought I can't see that as a plausible explanation, unless it's a spine that was prepared to look like a skull, on the presumption it really was one.--MWAK (talk) 07:57, 31 December 2014 (UTC)
replies: text: Juvenile could maybe be it, Darren Naish mentioned some unpublished stuff that will make Deinocheirus "even weirder" in one of his podcasts, and I don't think he refers to the brain study abstract, as the findings there don't really seem unexpected. And by the way, Reid, I don't think podcasts can be used as sources, especially not when as "informal" as the Tetzoo one... FunkMonk (talk) 15:40, 31 December 2014 (UTC)

text: Journal titles lowercased. I placed the cite doi references in the article as template:cite doi is supposedly no longer supposed to be used. If you want, I can revert my edits, but I have a different way to add references to the article that makes them very easy to edit and modify. Also, on the 31st and 1, I will be away from the PC, so I won't be able to help out with stuff. IJReid (talk) 04:12, 29 December 2014 (UTC)
replies: text: Alright, maybe my ref editing is a bit primitive, and it is also the part I like the least, hehe. As for the time around New Year, I won't be home either... By they way, the Holtz article cites an Ostrom article that seems important, as the first suggestion that this was an ornithomimosaur, could be nice to find it... FunkMonk (talk) 04:21, 29 December 2014 (UTC)
replies: text: The german article for John Ostrom mentions it under his selected publications, and has its full title, which the Holtz article and everywhere else I find this is lacking. This leads me to believe that someone on the german wiki has somehow gotten access to it, as it's unlikely that they just remembered it being one of his publications. Full article is: Ostrom, J.H. (19712). "Carnivorous dinosaurs" in McGraw-Hill Yearbook of Science and Technology for 1971 1971: 176–179. Another shot to get the full article would be to email Thomas Holtz to see if you get get it from him, as to cite it he probably had to have access to it. IJReid (talk) 15:21, 29 December 2014 (UTC)
replies: text: Perhaps a task for the resource request? And cripes, hadn't seen the supplemental material to the Natur epaper, will have to look over this for additional info... My vacation just ended, so writing will be a bit slower from now on, but it will be done... FunkMonk (talk) 22:56, 3 January 2015 (UTC)

text: I think the last step now would be to expand the lead. I would have it done by now but I know from personal experience that I tend to put too much info in it. The Nature paper itself has been used up, and the supplementary info for it mostly talks about discovery (added), distinguishing characteristics, and complex skull, vertebral, and limb morphology (to technical for laymen, especially the vertebral). The lead can be completed before the copyedit I believe, and once both are finished, this might be real close to GA standards. Before the copyedit comes along, I will read through it to see if I myself would pass it (I will try to avoid bias). IJReid discuss 15:33, 9 January 2015 (UTC)
replies: text: If you do the lead now, I can just tweak the parts that are too long afterwards. I'm sure it's ready for GAN now, but not really for FAC. Info is there, but the writing itself is not adequate in many places, and lacks cohesiveness because parts have been written by different people over the years (especially the history section). There's also some dramatic build-up needed, as mentioned below. When aiming for FAC, it is usually good to have it at almost FAC level before GAN, because then there won't be too much left to fix once it is nominated for FAC. FAC criteria also seem to becoming stricter, a lot of stuff was changed there recently, so it would not be a good idea to nominate prematurely. FunkMonk (talk) 16:38, 9 January 2015 (UTC)

text: Haven't found anything on it. The best I could find was in a pretend discussion on Dave Hone's blog, "R: Tish tish.  No matter.

IJReid discuss 01:06, 2 February 2015 (UTC)
replies: text: Heheh, weird! Since it isn't scientific information, even the DML could be used in this case. We don't need peer review for basic facts... By the way, what paper are the coordinates for the holotype site found in? FunkMonk (talk) 12:04, 2 February 2015 (UTC)

replies: text: Coolio! Now I'm fixing the last part of the lead, and then all we can do is wait for the GA review... And proof-read, of course. Hopefully more free photos will turn up too... The only part I'm uncertain about is the palaeoecology section, because I don't have access to most of the sources used. Not that there's anything controversial there, I'm just not sure how accurately they reflect the sources used. FunkMonk (talk) 03:53, 4 February 2015 (UTC)

message: , I understand the source might not be believable and I considered long enough whether I actually need to include this estimate, but I did because unlike some other estimations by the book (e.g. size based on braincase or illium which admittedly is unreliable), this was at least based on complete specimens. But what do you mean by messy? I've seen this type of writing in other articles (namely Dakoratpor and some other articles). Yes I thought about putting it as a separate sentence, but if I include this estimate as a separate sentence, the article looks messier (in my opinion) because the 2020 paper doesn't show a higher estimation in this case.
