message: What happened to the various species?
You have a small inconsequential list which is wrong btw... InGen's no longer exists...it's the female version of Longiceps if I'm not mistaken.
But where are
Sternbergi
Longiceps
Quetzocoatlyus (sp?)
etc.
There are many many versions but they are not mentioned or not described nor have I been able to find seperate articles for these.
This leaves the article highly fragmentary and misleading to have mention of only one form.

replies: text: Does anyone know the citation for the paper synonymizing longiceps and ingens? I remember reading about it years ago but seem to have lost the ref. A section on sexual dimorphism would be very useful in the article. Dinoguy2 18:34, 22 December 2006 (UTC)

text: Do ingens and longiceps have very different crests? I thought they looked pretty much the same, and a quick search seems to have both morphs labelled with both species names. Dinoguy2 03:52, 23 December 2006 (UTC)
thread_title:  Why is there no mention of the various species? 

message: Bennett (1994) concluded that : (1) only two species of Pteranodon are valid, P. longiceps Marsh, 1876 and P. sternbergi, and (2) P. occidentalis (Marsh, 1872), P. ingens (Marsh, 1872), P. velox (Marsh, 1872) P. comptus Marsh, 1876, P. harpyia (Cope, 1872), and P. umbrosus (Cope, 1872) are nomina dubia.

thread_title: Please don't revert last pop culture edit

message: I found these free pictures on Flickr, and they apparently show a Pteranodon skeleton cast at the Field Museum. But the crest is unfamiliar to me, and isn't featured on the species diagram in this article, so what is it? FunkMonk (talk) 21:09, 3 June 2009 (UTC)
replies: text: Obviously some variation of P. longiceps, but that's pretty weird. Would be interested to know the specimen number and how much is reconstructed. I doubt the beak would be that broad or straight, should be narrower laterally and up-curved. Dinoguy2 (talk) 02:09, 4 June 2009 (UTC)
replies: text: Could it be another genus then? And good job expanding this article, by the way! FunkMonk (talk) 13:00, 4 June 2009 (UTC)
replies: text: Just saw this, so it's just a crappy sculpt? FunkMonk (talk) 15:17, 4 June 2009 (UTC)
replies: text: Most likely. Most (all?) Pteranodon specimens are crushed flat so I'm guessing the "cast" making process leaves some room for incorrect interpretation. Most are also missing the anterior jaws so many incorrectly have their beaks straight as an arrow. I still wonder if there's some justification for that crest, seems too deviated from the standard to just be a mistake. But it still would be within range of individual variation for P. longceps (it's certainly not as different as the crest of P. sternbergi, though elsewhere at DinoForum there was an indication that the crest of the type on that one was pathological and P. sternbergi may be invalid too).

thread_title:  What kind is this? 

message: There's a P. longiceps at the AMNH that might work for the article:  It gives a good view of the whole animal. Then there's this one in flight that I don't remember seeing, but it's apparently there. Would any of those specimens do, when I embark on my quest for pictures?

replies: text: I think the plaque mount would be ideal, if we can remove any glare etc. Any 3D mounted skeleton will necessarily be a replica (not even a true cast) due to the mode of preservation. The 2D gives a sense of how these fossils are really found. MMartyniuk (talk) 04:46, 22 December 2010 (UTC)
replies: text: There are a few photos of both on Flickr, but they're not too good: . The head of the plaque mount is drawn, and looks like it was created in a way similar to this Nyctosaurus one which was inaccurate:  FunkMonk (talk) 08:26, 22 December 2010 (UTC)
replies: text: I believe it is an actual fossil (3D casts are hard enough to make as it is). And I think the posture could be okay---haven't figured out how they installed it yet, so it could just be compressed from being under another rock. Crimsonraptor (talk) 14:48, 22 December 2010 (UTC)
replies: text: There is no Pteranodon skeleton that complete in existence I believe, and certainly not in that condition. FunkMonk (talk) 16:11, 22 December 2010 (UTC)
replies: text: It's a cast, then. Crimsonraptor (talk) 17:32, 22 December 2010 (UTC)
replies: text: Almost all pterosaur fossils from the Niobrara Chalk are so compressed that parts are paper-thin (which is why the skulls and crests are so rarely preserved) so any display piece that has 3D elements is almost certainly at least partially a model (NOT a cast, a cast of a 2D preserved bone is still 2D). Many incomplete chalk-slab specimens simply have missing elements painted on. Often the entire slab is painted white to make it look more uniform (including the infamous nyctosaur crested specimens, where Dave Peters claimed to have found outlines of soft tissues, being unaware that the entire thing was painted). MMartyniuk (talk) 01:42, 23 December 2010 (UTC)
replies: text: That makes sense to paint the slab. But getting back to the original question, is the mount accurate enough? Crimsonraptor | (Contact me) Dumpster dive if you must 01:49, 23 December 2010 (UTC)
replies: text: Close enough, I'd say. The only major thing that stands out is the non-wing finger hands are too big and their finger lengths reversed (they should increase in length from 4 to 1). Here's a good recent composite skeletal for comparison:  MMartyniuk (talk) 01:58, 23 December 2010 (UTC)
replies: text: Hmmm. OK. I'll keep looking for other mounts then. Crimsonraptor | (Contact me) Dumpster dive if you must 17:04, 23 December 2010 (UTC)
replies: text: This photo is interesting, but has some problems. Does include a lot of the AMNH Pteranodon stuff on exhibit. FunkMonk (talk) 15:13, 29 December 2010 (UTC)
replies: text: That looks like the same cast that's currently in the taxobox... but it's among the best we're going to do I'm afraid. Nobody gets Pteranodon right, apparently. The lack of any complete male skulls in existence doesn't help. By the way I'm working on a revised version of the new comparison diagram already, mainly tweaking the grayed-out beak shape of longiceps to match some known isolated jaws. Should I upload both a Kellner and Bennet taxonomy versions just to be safe? MMartyniuk (talk) 00:32, 30 December 2010 (UTC)
replies: text: Yeah, that would be a good idea...Crimsonraptor | (Contact me) Dumpster dive if you must 02:50, 30 December 2010 (UTC)
replies: text: Yeah, and maybe put letters next to the heads so it's easier to see what description they correspond to? Also, one thing that might confuse readers is this "Unpreserved portions of skulls and jaws depicted in gray", since grey patterns have been used on the crests of male specimens. Some might be lead to believe this means the crests are incomplete, especially since the crest of Dawndraco is also grey and incomplete. FunkMonk (talk) 12:54, 30 December 2010 (UTC)

text: After uploading some PD photos of specimens, it appears that one of the specimen numbers in the diagram is wrong (YPM 2437 should be 2473), and the crests are drawn slightly more complete than they are? This diagram also shows the "male" Sternbergi as less complete than in the one we have:  FunkMonk (talk) 19:06, 8 January 2011 (UTC)

message: I noticed that a lot of the invalid species treated as valid,they aren't labeled valid but there notes and status boxes don't indicate that there invalid either,I can imagine someone skimming(no pun intended) would think that there valid.Secondly the notes of Pteranodon sternbergi should say that it's potentially Geosternbergia and the Geoternbergia section( sternbergi and maysei.)are synonyms of  Pteranodon sternbergi ,no question, shouldn't this be fixed?  — Preceding unsigned comment added by 142.176.114.76 (talk) 23:08, 14 September 2013 (UTC)

thread_title:  Classification 

message: The largest fossils of Pteranodon Longiceps/Ingens are up to 8 metres or more precisely 7.5 metres, not 7.2 metres. It was Pteranodon Sternbergi/Geosternbergia Sternbergi which was up to 7.2 metres. My question is Geosternbergia part of the Pteranodon genus since it is a synonym of P.Sternbergi?  — Preceding unsigned comment added by 112.134.14.176 (talk) 12:07, 2 May 2014 (UTC)
