Talk:Ankylosaurus

message: I've had a difficult time finding a definitive pronunciation of Ankylosaurus, and this article is no different in that it suggests two very different possibilities. Does anyone know how we can determine if the original pronunciation was intended to have the accent on the first or second syllable? Is the first "eng" or "ahn?" The second "kai" or "kee?" The difference between "ENG-kee-losaurus" and "ahn-KAI-losaurus" are very different indeed, and even this article's two different pronunciations aren't entirely clear. This site (http://dinosaurs.about.com/od/typesofdinosaurs/a/Ankylosaurus-Facts.htm) has some suggestions, but is also unclear. MXVN (talk) 07:46, 10 January 2012 (UTC)

text: How accurate is that reconstruction today? it resembles a lot reconstructions that Carpenter made in the 80s, which have been updated relatively recently and now resemble Greg Paul's, compare his Sauropelta and  Euoplocephalus from 1984 and 1982 to his new versions in the tree of life web project. I once tried to scale the vertebrae using the measurements in Carpenter (2004) and aside from the cervicals, the vertebral column of Carpenter's Ankylosaurus was too small to fit the dorsals and caudal. Mike.BRZ (talk) 19:24, 17 June 2015 (UTC)

text: Hmm, I don't know about the estimates, but I agree with FunkMonk on the topic of the size of the scale chart. The person seems a little short, maybe 1.5m. Based on my measurements and calculations if the human is 1.8 meters tall then the Ankylosaurus is 7.55 meters long. IJReid discuss 00:06, 12 July 2015 (UTC)
replies: text: Whoops, yeah looks like I made the tail too long in the original drawing. Corrected. "The nine metre estimate is from the same year as the Carpenter paper" This came from a volume published in 2004... as anybody who's submitted contributions for these kind of volume knows, that chapter was probably written in like 1998 ;) The Carpenter reference should be taken as a correction of older estimated based on less data. Paul's 7m estimate is within a meter of Carpenter's so I think those fall within the margin of error. Dinoguy2 (talk) 12:09, 12 July 2015 (UTC)
replies: text: Cool. By the way , perhaps you can help sort a thing out: What does "ankylosaur" refer to? Members of Ankylosauria? Or also just ankylosaurids? Would it be better to use ankylosaurian and ankylosaurid instead? FunkMonk (talk) 22:31, 12 July 2015 (UTC)

message: An IP replaced one instance of Edmontonia with Denversaurus, and though I know about the synonym situation, Carpenter 2001 only refers to an "Edmontonia sp.", not a specific species. Is this, whatever it is, now considered Denversaurus? Maybe  knows? FunkMonk (talk) 22:11, 20 January 2016 (UTC)
replies: text: Well, I think that most workers, Carpenter included, tend to accept that this is a separate taxon. If so, we might as well apply the available generic name Denversaurus — which has been more or less revived by Burns. However, for the sake of accuracy we should also mention that this has been considered an Edmontonia species.--MWAK (talk) 09:33, 21 January 2016 (UTC)
replies: text: Yeah, I guess Denversaurus/E. schlessmani is considered separate today, but how do we know the animal Carpenter refers to is that species, when he only said "Edmontonia sp."? Something to do with the age or formation of the fossils or something? Or have the specimens in question been reclassified as E. schlessmani since 2001? FunkMonk (talk) 14:49, 21 January 2016 (UTC)
replies: text: With "Carpenter 2001" you mean The Armored Dinosaurs? Then you have to help me a bit by indicating the precise article you are referring to. The index doesn't mention an Edmontonia sp.--MWAK (talk) 16:17, 21 January 2016 (UTC)
replies: text: Ah, no, Carpenter 2004! For example: "It was apparently contemporaneous with the nodosaurid Edmontonia sp., which is more common in the costal, “lowland” facies" and "These large plates are readily differentiated from those of the contemporaneous nodosaurid Edmontonia sp.". FunkMonk (talk) 16:23, 21 January 2016 (UTC)
replies: text: I see :o). This, I believe, largely refers to fragmentary nodosaurid material such as teeth and osteoderms, which were assigned to Edmontonia sp. because the genus was assumed present but a real species determination of the various remains was impossible. The assumption was based on the more complete Denversaurus material. So it shouldn't be read as a claim that a second nodosaurid species occurs in the strata. If the name Denversaurus should be come widely accepted, people will start referring to the same material as cf Denversaurus. It all sounds a bit more cognisant than Nodosauridae indet.--MWAK (talk) 19:54, 21 January 2016 (UTC)
replies: text: Ah... In that case, since it is so fragmentary, wouldn't it be best to keep the wording Carpenter uses in the original source? For us to call it Denversaurus specifically seems a bit like an original conclusion... FunkMonk (talk) 20:14, 21 January 2016 (UTC)
replies: text: The point is that, because our knowledge had been improved somewhat, the words Carpenter uses, get a different meaning in a modern context. Your own reaction proves this. Carpenter in 2004 had no intention whatsoever of making a distinction with Denversaurus — he was at the time convinced this was an invalid taxon. But today we can meaningfully ask ourselves "Is this Edmontonia sp Denversaurus?". So we can no longer correctly cite Carpenter using his own words! We have to explain the changed empirical context, if only in a footnote.--MWAK (talk) 18:45, 22 January 2016 (UTC)
replies: text: But are we sure the specimen in question is now considered Denversaurus specifically? Or is it just an indeterminate nodosaur? FunkMonk (talk) 21:56, 22 January 2016 (UTC)
replies: text: Saying "indeterminate nodosaur" and "Edmontonia sp." are the same thing. "Sp." here indicates indeterminate states, not a new species that has yet to be named. In Carpenter's nomenclature Edmontonia is a more inclusive clade, and the clade Denversaurus falls within it as a synonym. I would suggest calling this material nodosauridae indet. while the genus label for the only well supported species in the formation shakes itself out. This does not contradict Carpenter's meaning and does not introduce OR or imply that we can tell it's schelessmani rather than rugosidens or longiceps. Dinoguy2 (talk) 19:25, 23 January 2016 (UTC)
replies: text: That sounds right. Though does anyone know if the specimens in question are mentioned in any other paper? Couldn't hurt to cite that. FunkMonk (talk) 19:33, 23 January 2016 (UTC)

message: It seems that some recent ankylosaurine fossils have shown that spikes were present on at least the sides of the tails, but they have also been depicted with spikes all the way up to the sides of the body. So is our statement here from the old Glut book that "Likewise, large spines projecting sidewards from the body are present in many traditional depictions, but are actually only known in nodosaurids while being unknown in ankylosaurids" outdated now? Pinging , who added the text, and , as always... FunkMonk (talk) 16:54, 10 May 2017 (UTC)
replies: text: It all depends on your definition of "large". And on what phylogeny you use. Rows of more or less triangular side spikes had already been discovered in Pinacosaurus. Ziapelta has a 119 millimetres side spike.

replies: text: Fixed. Changed from "to them" to "together" Dinosaur(talk)🌴🦕🦖-- 00:04, 13 April 2020 (UTC)
replies: text: I think you should wait for answers here or at least check the source before making such changes. The source (Carpenter 2004) says: "The diapophyses are elongate, inverted tear-drop-shape byexpansion onto the ventral length of the transverse process,and by the fifth dorsal vertebra the diapophysis meets theparapophysis in an hourglass-shaped facet for the rib head, afeature also seen in Talarurus. This union eliminates thenormal gap between the diapophysis and parapophysis. In the last four dorsal vertebrae (d8–d11), their ribs are coossified to them indicating that these ribs were not involved in the bellows-like action of the more anterior ribs during respiration; fusion in Saichania begins with d6 (Maryanska 1977)." I am not entirely sure what the bolded "them" refers to, which would be the key to figuring this out. Maybe  can help out? I assume it means the rest of the ribs were not co-ossified with the corresponding vertebrae. FunkMonk (talk) 23:41, 13 April 2020 (UTC)
replies: text: My reading is that the ribs are coossified to the diapophyses, which makes them rigid and immobile as far as respiration is concerned. Lythronaxargestes (talk | contribs) 01:36, 14 April 2020 (UTC)

replies: text: I agree with Lythronax that "them" most likely refers to the diapophyses and parapophyses of the last four dorsals. Ribs generally aren't fused to vertebrae in dinosaurs (and many other animals), with this coossification being a rather distinctive trait in akylosaurs (I think). --Slate Weasel ⟨T - C - S⟩ 12:19, 14 April 2020 (UTC)

replies: text: Sort of. They did articulate, although there definitely wasn't as much mobility between the ribs and the vertebrae as between the tibia and femur.

thread_title: What does this mean?

message: I know this may be a speculation, but I believe that Ankylosaurus and some other large ankylosaurids were probably amphibious animals. Reasons? Its small relative, Liaoningosaurus, was most likely amphibious, and some features like the barrel-shaped body, its flared out nostrils, and its eyes located near the top of its head, which are all in some ways similar to some large amphibious mammals alive today, such as hippopotamuses. That's why I reconstructed Ankylosaurus here as a type of amphibious herbivore, not swimming though, but drifting through the water (like hippos), with fat to help keep the animal from sinking and struggling underwater.
Note that on Deviantart, dylan613 is my username. Anyway, that is just an idea I had since no one else seem to have notice that Ankylosaurus may have not been fully terrestrial. DinosaursRoar (talk) 17:50, 13 June 2020 (UTC)
replies: text: Well, since it is known from sediments representing upland areas, as stated in the article, that's probably not true for this genus. Also, its eyes are located pretty much at mid depth of its head, not near the top, and what would sideways facing nostrils help during aquatic behaviours? The nostrils would have to be on top for that to make sense. FunkMonk (talk) 18:25, 13 June 2020 (UTC)
replies: text: Additionally, Liaoningosaurus is quite compact, whereas Ankylosaurus and its close kin are more elongated (particularly the neck) and don't appear to be very streamlined. Also, some large ankylosaurids, like Pinacosaurus, inhabited arid regions, without appearing radically different from ones inhabiting milder regions (i.e. Euoplocephalus). Also, didn't ankylosaurins also have pretty compact hands and feet? This wouldn't be very ideal for a creature walking on soft substrates. Ankylosaurus external nares were located pretty far down on its skull, which would probably make it difficult for it to breathe. Additionally, in order for mentions of a possible amphibious lifestyle for this genus, something would have to be published in the peer-reviewed literature first to avoid WP:OR. --Slate Weasel ⟨T - C - S⟩ 14:14, 15 June 2020 (UTC)
