Alamosaurus & Utetitan size chart update

With the description of Utetitan, it would make sense to update the size chart, with the aim of de-Alamosaurus-ing it. Because all the North American titanosaurids are fragmentary, there is a load of uncertainty as to the size and proportions of these specimens. Possible update can be seen here. In this version, I have included the Alamosaurus type specimen, even though it's just a scapula.

One key issue is the large cervical series, BIBE 45854, which could impact nearly all the silhouettes. There are a couple of ways people have cross-scaled the specimen. One way is using the juvenile TMM 43621-1 as the primary guide, which results in larger-bodied restorations, like Paul's and Hartman's skeletals. The silhouettes in this diagram follow this interpretation. However, Tykoski & Fiorillo (2017) and a couple of online skeletals, have used a large-ish specimen, TMM 41541-1, that preserves both dorsals and cervicals. It seems to suggest a larger neck to body ratio. Alas, the specimen is not well described at the moment. For example, some of these interpretations suggest the BIBE 45854 cervicals come from an animal similar in size to USNM 15560, just with a large neck, like seen here and here, and here. Paul also briefly mentions the uncertainty over cross-scaling BIBE 45854, but does not specifically mention TMM 41541-1 as the reason for this. Steveoc 86 (talk) 00:07, 20 October 2025 (UTC)

It looks good to me! I think it’s smart to not just label them Utetitan and Alamosaurus and instead label them as the holotype of each, as I’ve seen some skepticism towards Utetitan and there’s a good chance it might become a nomen dubium in the future. Definitely NOT Dilophosaurus (talk) 18:43, 20 October 2025 (UTC)

Wouldn't it be better to label the chart as "Maastrichtian North American titanosaurs" (or titanosaurians), given that the use of the family Titanosauridae has been abandoned by most researchers? Sittaco (talk) 05:50, 24 October 2025 (UTC)

Yeah, I was just using the terminology in Paul's paper. I've changed to 'Titanosaurs' also fixed a typo.Steveoc 86 (talk) 11:28, 31 October 2025 (UTC)

The skull on lancensis is correct. This is based on a particular specimen, per the image description. Ddinodan (talk) 18:34, 31 October 2025 (UTC)

I'm aware, I don't think that sort of kink before the nasal fenestra is represented in the actual fossil. Definitely NOT Dilophosaurus (talk) 18:37, 31 October 2025 (UTC)

There is a ridge of keratin on the nasal. Ddinodan (talk) 18:41, 31 October 2025 (UTC)

I definitely appreciate it as an aesthetic choice, but for the sake of Wiki use it may be best to make the keratin ridge follow the shape of the nasal more closely, as the current shape does somewhat imply an incorrect skull shape. Definitely NOT Dilophosaurus (talk) 18:43, 31 October 2025 (UTC)

This is a non-issue and will not be adjusted. Ddinodan (talk) 18:46, 31 October 2025 (UTC)

The cranial profile is based on my schematic, which attempted to reconstruct the anteroposteriorly disarticulated cranium and account for taphonomic disturbance in the posterior skull (i.e jugal, squamosal, quadratojugal). Furthermore, said schematic was given some notes by James Napoli, who had said the reconstructed skull provided in Zanno and Napoli 2025 had issues in the scan mesh and sutural contacts, and more importantly, that the rostrum of NCSM 40000 was dorsoventrally flattened somewhat. With this in mind, the above reconstruction is perfectly reasonable, and strictly speaking, the "truest" form of the skull will be hitherto unknown until the forthcoming osteology is formally published. LancianIdolatry (talk) 18:57, 31 October 2025 (UTC)

Would it be possible to share this schematic? I can’t seem to find it and it would be helpful to be able to directly compare. Definitely NOT Dilophosaurus (talk) 19:07, 31 October 2025 (UTC)

I've decided to not make it public because there are several internal concerns that I have about it's cranial topology and I am far more content merely waiting for the osteology. More importantly though, I miscommunicated with Dan, and his art was based on an earlier and different edit of mines made in parallel with my schematic, and for that misunderstanding I apologize. With that in mind, many of the original comments still hold true- the shape is strictly unknown and what can be said and compared with N. lethaeus demonstrates the shape of the cranium in the above profile is still fine as-is. LancianIdolatry (talk) 19:34, 31 October 2025 (UTC)

I completely understand the logic, but I’m afraid I just don’t see a way that the head of the N. lancensis can fit into currently published reconstructions. I have no doubt that the schematic used is more accurate, but without being able to look at it there’s no way to verify. With that in mind, for me at least, the N. lethaeus is a PASS, but I’m afraid I have to say NEEDS REVISION for the N. lancensis, at least until the reference used can be made public. Definitely NOT Dilophosaurus (talk) 19:39, 31 October 2025 (UTC)

You can see the uncrushed skull under my illustration here: https://imgur.com/DxmXuqx

I am not adjusting the keratinous crest when it constitutes perhaps 3-5 pixels in height difference. I recall when Tameryraptor was published, almost the exact opposite was what was requested of me; that I deviate further from the existing material to satisfy what ultimately boils down to subjective opinions on what is and is not highly speculative.

Extremely minor things like these are not what constitute appropriate critique, and instead err on the side of nitpicking. Ddinodan (talk) 21:01, 31 October 2025 (UTC)

Gotcha. It’s definitely closer than I thought (though seems to be based on NCSM 40000 rather than the holotype as indicated by the description. But the nasal/premaxilla contact does seem to be displaced, and I still feel that the crest on the nose is a rather big deal as it significantly affects the silhouette. Definitely NOT Dilophosaurus (talk) 21:05, 31 October 2025 (UTC)

It is a crest. Of course it is going to affect the silhouette, it does so on every tyrannosaur reconstruction that has one.

The description does say NCSM 40000. Ddinodan (talk) 21:07, 31 October 2025 (UTC)

Unsure whether to flag this as revisions or pass, but I will say one thing though, that ornithomimid is small! Is it a juvenile? ~2025-31600-97 (talk) 01:32, 13 November 2025 (UTC)

both the Nanotyrannus and Tyrannosaurus here are missing an exoparia and have a jugal scale, which is most likely not the case. Also not sure about the quills on the Triceratops tail, it's not impossible but fairly unlikely considering what we have of trike integument. The plants in the background don't really seem to represent the Hell Creek paleoflora. I would recommend looking at the extinct pines and palms (ginkgos too, though they are rarer). Driptosaurus (talk) 09:40, 15 November 2025 (UTC)

@Driptosaurus The tyrannosaurus can easily be fixed but I'd say the Triceratops is a pass, even if we don't have fossilized evidence, there are many artworks showcasing quilled individuals. ~2025-31600-97 (talk) 19:44, 16 November 2025 (UTC)

Whoops, typo. Meant to say "tyrannosaurs". I was refering to both Nanotyrannus and Tyrannosaurus. ~2025-31600-97 (talk) 19:45, 16 November 2025 (UTC)

Yeah, I agree with that. Probably should have clarified that I thought the triceratops was usable. Driptosaurus (talk) 04:46, 18 November 2025 (UTC)

No the plants are accurate. Dawn redwoods and Sycamores were indeed found in Hell Creek. The Nano has an exoparia and both have a jugal scale. I can fix the Triceratops. Also, yes, it is a juvenile ornithomimid (hence the bigger eyes). --Bubblesorg (talk) 17:14, 18 November 2025 (UTC)

What I meant was more to do with the shape of the trees. Metasequoia is shown here to be growing very wide and not tapering very much, but that's not what we see in the genus. Most reconstructions give it sparser branches, as well. The Platanites looks okay to me. Driptosaurus (talk) 17:23, 18 November 2025 (UTC)

No. Many younger Metasequoia are tapering and are very bushy (which is what these are if you had to look at the size. The goldrush cultivated vars show this a bit better (probably because their growth is a bit more controlled), but wild individuals show this as well (https://starrosesandplants.com/plants/amber-glow-metasequoia/, https://www.vdberk.com/trees/metasequoia-glyptostroboides-goldrush-ogon/). --Bubblesorg (talk) 22:52, 7 December 2025 (UTC)

I added the scale chart as well, as it is based on the same image. I have a problem with the bipedal posture; unless I miss something, that's a very minority opinion and not something we would present as our life reconstruction of choice. --Jens Lallensack (talk) 17:04, 9 November 2025 (UTC)

This seems to be the most recent take on the debate [1], which argues for a bipedal posture, so bipedal posture is fine. --Jens Lallensack (talk) 17:11, 9 November 2025 (UTC)

Jens, I could be misinterpreting that source but it seems to mention quadrupedality as the prevailing hypothesis for Scelidosaurus while refraining from actually testing it since the study is focused on Scutellosaurus? -SlvrHwk (talk) 19:52, 9 November 2025 (UTC)

You are right of course – I completely missed that it is about Scutellosaurus and not Scelidosaurus. In my original comment, I had Norman's papers in mind; here he says that a bipedal posture is "unlikely", although in another one [2] he thinks it moved mostly quadrupedally but was able to move bipedally. As for the trackway evidence, the tracks have not, and cannot be assigned to Scelidosaurus so that should not really count as evidence. So if that is the case, it would be ideal if we could use a life reconstruction that shows the normal quadrupedal posture and use this one for the "Locomotion" section, to not give the false impression that this was a bipedal taxon. --Jens Lallensack (talk) 20:27, 9 November 2025 (UTC)
