History of Mantellisaurus
This page needs to be expanded, doesn't it? The citation for Mantellisaurus atherfieldensis should be (Hooley, 1925) [originally Iguanodon]. Also, I want you to create sections about the taxonomic history, behavior, diet, lifestyle, and geography of Mantellisaurus, and add references for Mantellisaurus. The names "Cetiosaurus" brachyurus, "C." brevis, Heterosaurus, Sphenospondylus, and Vectisaurus should be removed from the Iguanodon page. Of these five names, "C." brachyurus, Heterosaurus, Sphenosondylus, and Vectisaurus should be placed in synonymy with Mantellisaurus. "C." brevis, however, is actually a dubious eusauropod (Upchurch et. al., 2004), and referrable to Pelorosaurus, although iguanodont material assigned to "C." brevis is Mantellisaurus. Because "C." brevis is a macronarian, it should be included not in the synonymy of Mantellisaurus, but in the Pelorosaurus species list.

What did Paul (2006) comment on the synonymy of "Cetiosaurus" brachyurus, Heterosaurus, Sphenospondylus, and Vectisaurus with Mantellisaurus?

 * I was just thinking that someone could now write a cracking Mantellisaurus article now that we have all of the refs in the Iguanodon article. Paul didn't comment on the synonymy of other species and genera, but word is that a more detailed article is in the works, so until that's settled, it's safer to leave those species on the Iguanodon page (notice I added question marks to the taxobox). "C." brevis was chimeric, so I'll add that note to Iguanodon. J. Spencer 15:25, 17 February 2007 (UTC)

Sphenospondylus and Vectisaurus
McDonald (2011) can find no diagnostic characters for either Sphenospondylus or Vectisaurus and concludes that both are nomina dubia referable to Iguanodontia indet. McDonald doesn't address whether Heterosaurus is a nomen dubium or not.68.4.61.168 (talk) 00:05, 17 January 2012 (UTC)Vahe Demirjian

Heterosaurus
As pointed out by Lapparent and Stchepinsky (1968), the holotype of Heterosaurus neocombiensis is a chimera of at least three different groups: an iguanodont, an ichthyosaur, and a plesiosaur. The iguanodont elements have been redescribed by Martin and Buffetaut (1992), but the non-dinosaurian elements have yet to be restudied.

Orphaned references in Mantellisaurus
I check pages listed in Category:Pages with incorrect ref formatting to try to fix reference errors. One of the things I do is look for content for orphaned references in wikilinked articles. I have found content for some of Mantellisaurus's orphans, the problem is that I found more than one version. I can't determine which (if any) is correct for this article, so I am asking for a sentient editor to look it over and copy the correct ref content into this article.

Reference named "Paul2012": From Darwinsaurus:  From Huxleysaurus:  From Mantellodon:  

I apologize if any of the above are effectively identical; I am just a simple computer program, so I can't determine whether minor differences are significant or not. AnomieBOT ⚡ 04:23, 1 January 2020 (UTC)

Hello there! I'm from one of the most reputable paleontological sites, and I can say with confidence that we have two different species: http://www.polychora.com/dinolist.html#M. Here we see the following: Mantellisaurus Paul, 2006 Mantellodon Paul, 2012 (Опять Тамыч всё должен спасать...)The source is authoritative and always updated.

 * I'm sorry, your source is not as authoritative as the scientific literature. Mantellodon is based on a misdiagnosis and is clearly a nomen dubium per Norman 2013. Lythronaxargestes (talk &#124; contribs) 18:46, 15 January 2020 (UTC)

What? This list including ALL dinosaurs, and what the source for "Nomen Dubium"????????????????????????? 185.16.29.38 (talk) 13:19, 15 January 2020 (UTC) A.K.A. Tamaran — Preceding unsigned comment added by 185.16.29.131 (talk)
 * Hello, I guess as your website is russian and english is not your first language, let me explain. David Norman is the foremost expert on Iguanodon and other similar dinosaurs. The taxonomic history is complex here, but the very simplified story is. Is that Gregory S. Paul did NOT view the specimens in person when creating these species, which is a big no-no in paleontological circles. The paper where Norman declares the above taxa to be nomina dubia alreasy linked by LUSOTITAN but is located here. Hemiauchenia (talk) 17:02, 8 February 2020 (UTC)
