Siamosaurus (edit | talk | history | links | watch | logs)

Nominator(s): ▼PσlєοGєєкƧɊƲΔƦΣƉ▼ 22:08, 10 June 2020 (UTC)

This article is on a mysterious genus of semiaquatic dinosaur from the Early Cretaceous of what is now Thailand. If it passes review, it will be Wikipedia's fifth spinosaurid FA, probably our longest article on an animal known only from teeth, and the second FA on a dinosaur tooth taxon after Dromaeosauroides. Though fragmentary in nature and potentially dubious, hope you'll find this an interesting read and a good example of how much we can glean about ancient life from even the tiniest pieces of fossil material. Comments and suggestions very welcome. Thanks in advance! ▼PσlєοGєєкƧɊƲΔƦΣƉ▼ 22:08, 10 June 2020 (UTC)

  • Support - I had my say at the peer review. Incredible how much that can be written about a bunch of teeth. Looks fine to me! FunkMonk (talk) 09:00, 11 June 2020 (UTC)
One thing, maybe it's an overstatement to say "Annotated skull diagram of the closely related Spinosaurus", considering their distance in the cladogram? FunkMonk (talk) 19:31, 13 June 2020 (UTC)
Good point! Fixed. ▼PσlєοGєєкƧɊƲΔƦΣƉ▼ 20:36, 13 June 2020 (UTC)
Hmmm, PaleoGeekSquared, might be in order to notify projects or ping potential reviewers about this nomination, since it is getting a bit far down the list... FunkMonk (talk) 23:17, 24 July 2020 (UTC)
Woah, hadn't even realised this had been here for one and a half months already, probably due to the length and technical nature of the article. - perhaps Casliber, Lusotitan, or IJReid would be willing? ▼PσlєοGєєкƧɊƲΔƦΣƉ▼ 11:21, 25 July 2020 (UTC)
  • Comment: Hi. I'm not familiar with palaeontology articles, but approaching the subject from a Thailand viewpoint, I wish the History of discovery section would provide a bit more background to help place the fossil within the context of the early discoveries from Phu Wiang during the 1980s–90s. I understand that S. suteethorni was the first ever dinosaur species described from Thailand? --Paul_012 (talk) 18:22, 15 June 2020 (UTC)
Good point, if it was indeed the first dinosaur genus named from Thailand (the species but not genus "S." fusuiensis was named before at least), I think it would also warrant mention in the intro. And if fusuiensis was the first species named, that would of course also warrant mention, but we can only do this if there are sources that state it outright. FunkMonk (talk) 18:28, 15 June 2020 (UTC)
"S." fusuiensis wasn't from Thailand, though? --Paul_012 (talk) 21:29, 16 June 2020 (UTC)
Ah, good point again, I guess my mind got confused after the articles were merged a while ago. FunkMonk (talk) 21:59, 16 June 2020 (UTC)
I checked the naming dates of all other Thai dinosaurs and this does seem to be the case; the first bones discovered were of Phuwiangosaurus, but Siamosaurus was the first formally named. I'm finding it surprisingly difficult to locate sources explicitly stating this though, the best I've been able to find is that Siamosaurus is the first reported spinosaurid, which is what is already in the lead and article. ▼PσlєοGєєкƧɊƲΔƦΣƉ▼ 09:52, 28 June 2020 (UTC)
Image review
  • File:Siamosaurus suteethorni model.jpg and File:Siamosaurus suteethorni sculpture Phu Wiang Dinosaur Museum.jpg are marked disputed accuracy at Commons.
Since I was the one recommending to tag them as such, I might as well explain. Images tagged as anatomically inaccurate are still usable in sections about historical or cultural significance. They are not to be used in other sections, though, unless to specifically illustrate outdated ideas. Also pinging PaleoGeekSquared, have you seen the comments above?

Support from Jens LallensackEdit

Impressing article, so much for a few teeth!

Look like it's been quiet here for some weeks so many thanks for the review! ▼PσlєοGєєкƧɊƲΔƦΣƉ▼ 09:52, 28 June 2020 (UTC)
  • palaeontologists Rubén Molina-Pérez and Asier Larramendi in a 2016 book – I think we have to be more careful with selecting reliable sources. See my points on this particular book here, would be great if you could provide your thoughts there.
I agree that such books, unless cited or mentioned in the scientific literature, are best reserved for uncontroversial info. I've read the Theropods book myself and it seems to have some very speculative or questionable content, such as the section on the running speed of various extinct theropods and dinosauromorphs. I think the size estimates can probably be kept though as long as there's not that many others available and its clarified in text what the type of source is, which I've just done. ▼PσlєοGєєкƧɊƲΔƦΣƉ▼ 09:52, 28 June 2020 (UTC)
The size estimates may be an edge case and I do not have a strong opinion on that. But I fear that systematic decision regarding Siamosaurus? fusuiensis that this book made has to be removed. It is not really relevant since it has no bearing on science (it is not a book that can be taken serious and be cited by scientists in the first place). The theropoddatabase, the personal website of Mortimer, is another difficult case, maybe a bit more unclear; the systematic decisions published there are also not cited in the scientific literature at all. I would therefore also argue to exclude them, as systematic decisions are always highly controversial. --Jens Lallensack (talk) 10:12, 28 June 2020 (UTC)
Fair point, done. ▼PσlєοGєєкƧɊƲΔƦΣƉ▼ 10:28, 28 June 2020 (UTC)
  • Siamosaurus sp. – sp. should not be in italics.
Yeah, realized I was accidentally doing that in multiple articles, looks like I missed one! Fixed. ▼PσlєοGєєкƧɊƲΔƦΣƉ▼ 09:52, 28 June 2020 (UTC)
  • A Siamosaurus tooth found nearby indicates the skeleton may belong to this genus, though this could also represent evidence of scavenging. – Here it is crucial to state if this is a tooth crown or a complete tooth with root. If it was a scavenger, I expect a tooth crown (the root got resorbed and the crown fell out when it was replaced by a new tooth), but if it was from a skeleton, I expect a complete tooth (which fell out, complete with root, only after the death of the animal).
That would definitely be helpful! But I checked the sources again and unfortunately it is just stated that it was a tooth and not really clarified beyond that. ▼PσlєοGєєкƧɊƲΔƦΣƉ▼ 09:52, 28 June 2020 (UTC)
  • such as a skull or body fossilbody fossil has its own meaning (the opposite of a trace fossil), and the skull is a body fossil.
Reworded to "such as a skull or postcranial skeleton", is that better? ▼PσlєοGєєкƧɊƲΔƦΣƉ▼ 09:52, 28 June 2020 (UTC)
  • Viewed distally (from away from the centre of attachment) – this is misleading. Distal view means the view towards the centre of attachment, as you are looking at the distal end. Just as "anterior view" means "front view".
Fixed. ▼PσlєοGєєкƧɊƲΔƦΣƉ▼ 09:52, 28 June 2020 (UTC)
  • since ceratosaur teeth differ in cross section – can this be more specific? E.g. "are more narrow"?
Done. ▼PσlєοGєєкƧɊƲΔƦΣƉ▼ 09:52, 28 June 2020 (UTC)
  • Spinosaurus aegyptiacus from Egypt, whose fragmentary fossils had been destroyed during World War II. Like Siamosaurus, this African genus – This refers to S. aegyptiacus, which is a species not a genus.
Changed to "taxon". ▼PσlєοGєєкƧɊƲΔƦΣƉ▼ 09:52, 28 June 2020 (UTC)
  • that since crocodilian teeth are usually more strongly recurved than spinosaur teeth, they cannot represent the same taxon – I can't follow, which taxon?
Changed to "they can be distinguished from each other". ▼PσlєοGєєкƧɊƲΔƦΣƉ▼ 09:52, 28 June 2020 (UTC)
  • may have spread from west to eastern Laurasia—the northernmost supercontinent – "western"? Furthermore, I would use "northern" instead of "northernmost", since it is the only northern supercontinent. --Jens Lallensack (talk) 21:30, 27 June 2020 (UTC)

Coord noteEdit

I'm adding this to the urgents list for a third comprehensive review and also to the source reviews list. --Ealdgyth (talk) 15:44, 7 July 2020 (UTC)

Source review - spotchecks not done

  • FN35 appears to be a children's book - is there no better source supporting this claim? Ditto FN36
Given how obscure this dinosaur is, published size estimates are few in number so these are the best and only good sources I could find. Their authors include dinosaur expert Don Lessem and palaeoartist Jan Sovak (who has illustrated works by scientists such as Phil Currie); and palaeontologists such as Darren Naish and David Martill, so they should be sound in terms of reliability. ▼PσlєοGєєкƧɊƲΔƦΣƉ▼ 09:17, 17 July 2020 (UTC)
Is there a particular reason why size estimates would be published uniquely in children's books? Nikkimaria (talk) 20:27, 18 July 2020 (UTC)
Not particularly, size estimates can be found both in popular books by palaeontologists (like those by Gregory S. Paul[1] and Thomas Holtz[2]) and journal articles[3][4], so usually it just depends on what might be available for that particular animal. ▼PσlєοGєєкƧɊƲΔƦΣƉ▼ 11:21, 25 July 2020 (UTC)
  • What makes a high-quality reliable source?
The author, Mickey Mortimer, has co-authored published, peer reviewed-papers. However I've just removed the second instance where this is cited, since systematic decisions on the assignment of fossil material should probably be reserved for better sources. So this ref is now only citing uncontroversial information that I haven't found anywhere else (the note about the paratypes). ▼PσlєοGєєкƧɊƲΔƦΣƉ▼ 09:17, 17 July 2020 (UTC)
  • News sources that have a full publication date, should include that date in their citations
Done. ▼PσlєοGєєкƧɊƲΔƦΣƉ▼ 09:17, 17 July 2020 (UTC)

Done. ▼PσlєοGєєкƧɊƲΔƦΣƉ▼ 09:17, 17 July 2020 (UTC)
  • If publication locations are to be included, they should be in the |location= parameter, but this should be consistent
Done. ▼PσlєοGєєкƧɊƲΔƦΣƉ▼ 09:17, 17 July 2020 (UTC)
  • FN13: if no other source has reported on this, don't think it warrants inclusion. However if the citation is kept it needs reformatting
Citation kept as it goes into a bit more detail on Phu Wiang Museum. Reformatting done. ▼PσlєοGєєкƧɊƲΔƦΣƉ▼ 09:17, 17 July 2020 (UTC)
Why does that warrant inclusion? (Now 11 and 13 are the same) Nikkimaria (talk) 20:27, 18 July 2020 (UTC)
Sorry, forgot to clarify! FN11 notes that Siamosaurus fossils are housed in Phu Wiang Museum; FN12 mentions fossils are also housed in Sirindhorn museum, as well as the sculpture outside the building; and FN13 mentions the Siamosaurus model inside Phu Wiang museum. ▼PσlєοGєєкƧɊƲΔƦΣƉ▼ 11:21, 25 July 2020 (UTC)

Fixed. ▼PσlєοGєєкƧɊƲΔƦΣƉ▼ 09:17, 17 July 2020 (UTC)
Not fixed. For example FN16 include publisher and location while FN28 includes neither. Nikkimaria (talk) 20:27, 18 July 2020 (UTC)
I've added the location name, but the publisher (SVPCA) would have to be a duplicate of the journal title, which is a required field, so let me know what I should do in this case or if I should use another template. ▼PσlєοGєєкƧɊƲΔƦΣƉ▼ 11:21, 25 July 2020 (UTC)
I see you've added SVPCA, which is fine, but I'm still seeing inconsistencies - for example in FN17 you've shoehorned a bunch of content into the publisher parameter. Nikkimaria (talk) 01:47, 26 July 2020 (UTC)
  • What makes ResearchSEA a high-quality reliable source?
Reliable news platform sharing scientific research, turns up numerous hits on Google Scholar[5][6]. ▼PσlєοGєєкƧɊƲΔƦΣƉ▼ 09:17, 17 July 2020 (UTC)
Which of those hits do you believe demonstrate its reliability? Nikkimaria (talk) 20:27, 18 July 2020 (UTC)
Among others, these papers[7][8][9], which cite articles published on ResearchSEA. ▼PσlєοGєєкƧɊƲΔƦΣƉ▼ 11:21, 25 July 2020 (UTC)
  • What makes PalArch's a high-quality reliable source?
Reputable Dutch science journal, also heavily cited on Google Scholar[10]. ▼PσlєοGєєкƧɊƲΔƦΣƉ▼ 09:17, 17 July 2020 (UTC)
Which of those hits do you believe demonstrate its reliability? Nikkimaria (talk) 20:27, 18 July 2020 (UTC)
Same as above[11], and it's also been cited in multiple recent featured dinosaur articles with no doubts about its reliability, including Gallimimus, Dilophosaurus, Ceratosaurus, Segnosaurus, and Irritator. ▼PσlєοGєєкƧɊƲΔƦΣƉ▼ 11:21, 25 July 2020 (UTC)
  • FNS 31 through 33 should use more specific titles and |publisher=Sirindhorn Museum instead of |website=

Not done - "instead of", not both. Nikkimaria (talk) 20:27, 18 July 2020 (UTC)
I'm a bit stumped on what to do here, could you please clarify? I see only templates for websites, journals, books, news and just the simple basic form, But nothing for 'publisher'? My brain kinda melts when it comes to citation templates so sorry if it's a dumb question. ▼PσlєοGєєкƧɊƲΔƦΣƉ▼ 11:21, 25 July 2020 (UTC)
It's not a separate template, it's a matter of which parameters are being used - each of those templates includes a separate parameter for a publisher versus a work title (website, journal title, etc). Right now both are included in these citations, and what I'm saying is that they shouldn't be. Nikkimaria (talk) 01:47, 26 July 2020 (UTC)
WP:SCHOLARSHIP states that theses can be used as long as they have undergone sufficient academic rigour, in this case the dissertation was supervised by professors Dr. Thomas Martin and Martin Sander, two respected German palaeontologists. ▼PσlєοGєєкƧɊƲΔƦΣƉ▼ 09:17, 17 July 2020 (UTC)
