== Semi-protected edit request on 18 April 2024 ==
== Tyrannosaurus' Status as Largest Land Predator ==


{{edit semi-protected|Tyrannosaurus|answered=yes}}
The article is very conservative about Tyrannosaurus' status as the largest land predator ever discovered. While the holder of this noteworthy record was hotly disputed as recently as the 2000s, taking on almost the tone of a political argument, the picture has become much clearer over the last 10 years. Thanks in part to more sophisticated and accurate computer models, Tyrannosaurus' body mass estimates have been bumped up significantly, as the article itself reflects. On the other hand, the known fossils of the three only other true contenders--Carcharodontosaurus, Giganotosaurus, and Mapusaurus--have been shown to have had their lengths overestimated, and were not as massive as equivalent tyrannosaurids to begin with. Spinosaurus, the only remaining theropod longer than Tyrannosaurus, has been shown to be less massive still, as well as mostly aquatic, casting doubt on its eligibility for the status of "land predator," or at least "obligate land predator."
The image titled "Holotype of ''Nanotyrannus lancensis'', now interpreted as a juvenile ''Tyrannosaurus''" is not of the holotype, but a cast of the holotype. The caption also implies that this specimen has been definitively interpreted as a juvenile despite ongoing debate. The debate is discussed in the main article text. I would suggest that the image caption be changed to "Cast of CMNH 7541, the holotype of ''Nanotyrannus lancensis'', sometimes interpreted as a juvenile ''Tyrannosaurus''."

== pre-print cite? ==
It's important to note that size is conventionally measured as mass, not length or height, which is why the African bush elephant, not the reticulated python or the giraffe, is uncontroversially considered the largest living terrestrial animal.
I would further like to note that all of these length and mass estimates are borne out on their respective Wikipedia articles. On the Carcharodontosaurus article, it unselfconsciously describes the animal as the "5th largest theropod overall according to most estimates." The Mapusaurus article calls its subject "slightly smaller in size than (...) Giganotosaurus" at "over 5 metric tons (...) at maximum." The Giganotosaurus article, in turn, admits that Tyrannosaurus "has been considered the largest theropod historically," that "the incompleteness of (Giganotosaurus') remains have made it difficult to estimate its size reliably," and that "some writers have considered the largest size estimates for both specimens exaggerated," listing this allegedly exaggerated estimate for the largest specimen at 8.2 metric tons, which even then is still well below the by far more accepted 8.87 metric tons listed in the Tyrannosaurus article. Finally, the Spinosaurus article puts the maximum weight for its subject's up-to-date reconstruction at 7.4 metric tons, before noting that the newest studies consider even this relatively low mass an overestimate which "cannot be considered a reliable body size estimate."


" In a subsequent paper awaiting publication, Paul maintained ... " ref 84 -- I thought the agreement above was not to use pre-prints? [[Special:Contributions/2603:6080:21F0:6000:7DFA:6CB7:3E68:895D|2603:6080:21F0:6000:7DFA:6CB7:3E68:895D]] ([[User talk:2603:6080:21F0:6000:7DFA:6CB7:3E68:895D|talk]]) 22:20, 30 May 2024 (UTC)
As a result, this otherwise great and cutting-edge Tyrannosaurus article smacks of being unduly cautious and downright dated whenever it comes to placing its subject in the size hierarchy. Especially the following phrase in the otherwise beautiful lead sounds like it hasn't been updated in a decade: "Although other theropods rivaled or exceeded Tyrannosaurus rex in size, it is still among the largest known land predators (...)." And in the Size section, in "T. rex was one of the largest land carnivores of all time," the qualifier "one of" sounds almost absurd followed by the staggering but uncontroversial updated mass estimates--that comfortably exceed even the most exaggerated estimates of any of the other theropods in the accompanying infographic, as I pointed out above.


== Semi-protected edit request on 21 July 2024 ==
I suggest that this article be edited to plainly inform the reader about what the majority of scholars seem to have concluded: Tyrannosaurus was (by a nontrivial margin) the largest (i.e. most massive) land predator ever discovered. Only one theropod dinosaur, Spinosaurus, has been discovered that was conclusively longer. However, Spinosaurus was both less massive as well as not an obligate land predator.


{{edit semi-protected|Tyrannosaurus|answered=yes}}
At minimum, the awkward, apologetic statement in the lead "(Tyrannosaurus) is still among the largest known land predators" should be revised or omitted so that it doesn't convey the impression that some unexpected recent developments have been eroding Tyrannosaurus' relative size, contradicting popular perception in dramatic fashion along the way. The opposite has been the case: 1. Tyrannosaurus' relative size has increased significantly. 2. The new sensationalist attitude is much closer to trying to "top" Tyrannosaurus, that anything but Tyrannosaurus must be the record holder, whereas Tyrannosaurus itself is "old news." I hope go-to sources like this Wikipedia article haven't added any fuel to the flames here.
Some of the T Rex measurements are outdated and I would like to fix them. The T Rex weight measurements have been changed since Wikipedias last edit. New larger T Rex specimens have been discovered. [[User:Tom Friedman|Tom Friedman]] ([[User talk:Tom Friedman|talk]]) 15:43, 21 July 2024 (UTC)

== Ornithomimus Grandis? ==
If this suggested remedy is still too much, then at the barest minimum those other theropod articles should be edited to no longer unanimously defer to the subject of this article as an almost undisputed record holder, in order to make the Wiki more consistent.


Fossil material belonging to Tyrannosaurus that was found in eastern Wyoming in the 1890’s and described in 1896 by Marsh. He thought it belonged to Ornithomimus and named it “Ornithomimus grandis”. Should that be a synonym of Tyrannosaurus, Deinodon, or just not one at all? [[User:Smilus32|Smilus32]] ([[User talk:Smilus32|talk]]) 16:10, 4 December 2024 (UTC)
I wasn't bold enough to just go ahead and cut open this beautiful article without consulting the community, so I'm hoping this can be the spark that inspires somebody to make some positive revisions. Needless to say, the question "Which was the largest known land predator?" has taken on historical, almost mythological proportions. Calling public interest "high" would be an understatement.
:The citation is Marsh (1890) but recent literature considers it similarly to ''Manospondylys gigas''. ''[[User:Lythronaxargestes|Lythronaxargestes]]'' ([[User talk:Lythronaxargestes#top|talk]] &#124; [[Special:Contributions/Lythronaxargestes|contribs]]) 16:32, 4 December 2024 (UTC)

tl;dr:
Tyrannosaurus is the largest land predator ever discovered by a nontrivial margin; size is measured by mass; the article makes it sound like other land predators approaching or exceeding Tyrannosaurus' body mass have been discovered, even though the articles for those land predators disagree, and the math from all the mass estimates even in the articles themselves contradicts this; the record for the largest land predator of all time is noteworthy and interesting to the public [[Special:Contributions/2001:9E8:8FC:AE00:983:4A5B:7C9:C387|2001:9E8:8FC:AE00:983:4A5B:7C9:C387]] ([[User talk:2001:9E8:8FC:AE00:983:4A5B:7C9:C387|talk]]) 10:21, 15 September 2023 (UTC)

== Nanotyrannus valid again? ==

Nick Longrich has recently published a paper: [https://osf.io/preprints/paleorxiv/nc6tk/?fbclid=IwAR2anhEa67Jo93tggq0bXzmY-E9n2c9cXQ0R11-o244kzcMaenaDlZ3_yrU]https://osf.io/preprints/paleorxiv/nc6tk/?fbclid=IwAR2anhEa67Jo93tggq0bXzmY-E9n2c9cXQ0R11-o244kzcMaenaDlZ3_yrU detailing why Nanotyrannus may, in fact, be a separate genus from Tyrannosaurus after all, and how several specimens conventionally believed to be juvenile Tyrannosaurus are actually Nanotyrannus. Moreover, he points out that many of Nanotyrannus’s features are not similar to those of Tyrannosaurids at all, but group closer to more basal tyrannosaurs.

Does this mean Nanotyrannus is finally established as a separate genus, and ought to be referred to as such on Wikipedia? [[Special:Contributions/135.135.227.26|135.135.227.26]] ([[User talk:135.135.227.26|talk]]) 21:49, 25 October 2023 (UTC)

:::When/if a journal accepts it. Bear in mind a single paper is by no means an end to the ongoing debate, and it's unlikely to not be contested.

[[User:FunkMonk|FunkMonk]] ([[User talk:FunkMonk|talk]]) 22:24, 25 October 2023 (UTC)
::::Mostly because I personally talked to Longrich about it, and mentioned several of the commonly-cited reasons why Nanotyrannus is considered invalid, and his reasoning for considering it a valid genus regardless seems solid to me. For example, the Montana Dueling Dinosaurs specimen is a subadult, but its arms are larger than those of adults.

::::::The paper has now been published. We have to keep in mind that the consensus has never been based on good data. ''Nanotyrannus'' shares no autapomorphies with ''Tyrannosaurus'' so there is no strict proof the two are identical. But there is no cogent proof that they are not identical either, so most see it as more parsimonious to assume that there is only a single species. The text presently too much suggests that ''Nanotyrannus'' unproblematically fits the morphology expected for a juvenile in a tyrannosaurid growth series.--[[User:MWAK|MWAK]] ([[User talk:MWAK|talk]]) 18:00, 3 January 2024 (UTC)
:::::::We also need to be aware that this is certainly not a settled argument and will continue for years to come. Representatives from the other camp have already criticized the paper[https://www.newscientist.com/article/2410573-tiny-t-rex-fossils-may-be-distinct-species-but-not-everyone-agrees/], so we can be sure there will be published rebuttals.

== Nanotyrannus vs. Tyrannosaurus ==

::We don't need "scattered articles throughout the Internet", we have scientific papers, and that's what we're already citing. The Nano article wasn't deleted, it was merged into this one.

== Tyrannosaurus mcraeensis ==

As of today, [https://www.nature.com/articles/s41598-023-47011-0 a new species of Tyrannosaurus] has been described in a paper published by Nature. This species, ''Tyrannosaurus mcraeensis'' predates ''T. rex'' by 6-7 million years yet is about as large. Given the utter depth at which this article goes into ''T. rex,'' how will we fit this new information on this new species into this page? For so long, ''Tyrannosaurus'' has been a monotypic genus, and save for that one little Greg Paul moment that was roundly rejected, no new species have been added til now.
How are we going to proceed with this?

The caption also implies that this specimen has been definitively interpreted as a juvenile despite ongoing debate. The debate is discussed in the main article text.
