Gomphothere genera

The Wiki article for Amebelodon seems to have much more information than that of Platybelodon, including some information about Gomphotheres. I don't have time at the moment, but: a good start would be to regularize those two genera pages. --148.87.1.171 20:37, 2 August 2006 (UTC)

Needs revision

The Wikipedia entries on this family, and on most of the proboscidean genera, are out of date. Gomphotheriidae sensu lato is not a valid group. Most of the proboscideans that are called "gomphotheres" on Wikipedia have been reclassified in different families: Stegomastodontidae, Tetralophodontidae, Anancidae, and Ambelodontidae. Gomphotherium is no longer considered the universal ancestor of all mastodonts. -- 97.116.22.77 (talk) 17:35, 13 February 2009 (UTC)

Spelling

Reliable sources use both Gomphotheriidae and Gomphotheridae. Please explain this in the article. --Una Smith (talk) 15:45, 22 August 2009 (UTC)

Extinction date of 400 CE is dubious

I have been trying to validate the 400 CE extinction date specified in this article. The reference given in the Wiki article is just an encyclopedia entry that specifically ties this date to cuvieronius. The words in the encyclopedia entry itself are also very speculative, saying things like "cuvieronius probably died out as recently as 400 CE," but then giving no scholarly backup for this date.

I also tried for several hours to search through the scientific literature, but was unable to find any articles that validate the 400 CE date. This date seems especially dubious when one considers that virtually every other form of megafuana in North America seems to have died off around 8,000-10,000 years ago (at the very most recent). Until someone can provide a real peer-reviewed source for this number, it should be called into question. —Preceding unsigned comment added by Nageljr (talk • contribs) 19:56, 9 April 2010 (UTC)

Link to german Version and Dating

I think, the link to the german Version of the Article is false. It leads to the Gomphoterium, which is only one part of this Family (here is the english Article to this). As far as I understand this, the correct Link should be this one: Gomphoterien.

Also in the german article it is mentioned, this Family lived from 28.4 Mio onwards till 11,000 Years (should be 9.000 Years BC), the Article here says something from 12 Mio Years till 1.6 Mio. I really would like to find out, which time-span is now the correct one. Please forgive me my bad english -- Hartmann Schedel ^Prost 09:41, 7 July 2010 (UTC)

Why Are The Dates Of The Article In BP As Opposed To BC?

Why are the dates of the article in BP as opposed to BC? Everyone who reads the article is not going to understand the dates unless they read and further research the shoddy Wikipedia article on BP connotation.23.16.152.103 (talk) 17:20, 27 August 2012 (UTC)BeeCier

Gomphothere and Clovis culture?

A recent article made the front page of Science Daily: Bones of elephant ancestor unearthed

It seems like this is good information to be added, but I wanted to share and discuss before doing so. Challenger l (talk) 11:29, 15 July 2014 (UTC)

Seems To Have Been Copied

Aspects of this article suggest that it has just been copied from articles in scholarly journals. For instance, in the section on diet, it describes the creatures as having C3 and/or C4 diets, with absolutely no explanation of what those obviously technical terms mean. This article should be substantially revised to be understandable to the layman.

it also focuses on the technical without being very thorough on the group as a wholeTheDarkMaster2 (talk) 15:51, 22 January 2020 (UTC)

Clarification

Did the gompotheres emerge in America or Eurasia, because the article implies it emerged in America, where I'm pretty sure the group emerged in eurasia before being pushed into the Americas with the emergence of Elephants, Mammoths, and StegodontsTheDarkMaster2 (talk) 15:50, 22 January 2020 (UTC)

@TheDarkMaster2: The problem is that the taxonomy of Gomphotheres is currently in a state of flux, and the term gomphothere historically referred to proboscideans that were more derived than mammutids, but less derived than elephantids. There are loads of proboscidean taxa that sort of fall into that grade likeAnancus that aren't even techincally considered gomphotheres. The article does need a proper rewrite though. Hemiauchenia (talk) 16:22, 22 January 2020 (UTC)

You are correct, but it has been settled that all the ones currently considered part of the gomphotheres are part of it. Gomphotherium is still a gophotheres. I just think it should be reworked, especially as some one interested in elephantsTheDarkMaster2 (talk) 21:40, 22 January 2020 (UTC)

@TheDarkMaster2: Not really, a bombshell collagen sequencing result has just come out suggesting that Notiomastodon is more closely related to the american mastodon than to extant elephants. I remember reading a conference abstract from Mothé et al where they state that the brevostrine clade was closer to extant elephants than classical gomphotheres, thought I can't find a link at the moment. Hemiauchenia (talk) 21:47, 22 January 2020 (UTC)

Do you mean Stegomastodon? Haplomastodon? or Notiomastodon? This is very hard, of course it all changes suddenlyTheDarkMaster2 (talk) 21:52, 22 January 2020 (UTC)

@TheDarkMaster2: South american Stegomastodon=Haplomastodon=Notiomastodon, Notiomastodon is the preferred name due to priorty. The taxonomic history is incredibly convoluted and complex, the paper explaining all of it is here, and is essentially required reading to understand this mess. Hemiauchenia (talk) 22:00, 22 January 2020 (UTC)

So are they going to fuse all three genera? Cause the main discussion only seems to be with Haplomastodon and NotiomastodonTheDarkMaster2 (talk) 22:09, 22 January 2020 (UTC)

@TheDarkMaster2: No as Stegomastodon is a valid genus for the North American species, and the South American "Stegomastodon" species aren't closely related to the North american ones according to phylogenetic results. Hemiauchenia (talk) 22:19, 22 January 2020 (UTC)

Ah ok, so there's still three genera. I understand now. I still find it problematic to fuse some of these genera, if only for the fact that fossils can't tell you everything. (Lions and tigers have very similar skeletons once the skin is removed). So to truly know the diversity of south american gompotheres is an unfortunate impossibility — Preceding unsigned comment added by TheDarkMaster2 (talk • contribs) 12:08, 23 January 2020 (UTC)

Gomphothere → Gomphotheriidae – Taxonomic fossil families pages like that of the Gomphotheriidae should be named by family names and not "common" taxonomic names, similar to other pages such as the Deinotheriidae and Mammutidae.

• Oppose "Gomphothere" is the firm WP:COMMONNAME for this group of fossil proboscideans. It's used for the title of the Britannica article for instance [1]. "Gomphothere" is widely used in the scientific literature [2] as well as the lay press. Basically all proboscidean workers agree that Gomphotheres are a paraphyletic group, as Elephantidae and Stegodontidae are derived from gomphothere ancestors. There have been numerous taxonomic attempts to classify gomphotheres to resolve the issue, some deliberately avoiding using "Gomphotheriidae" for some of the taxa generally considered gomphotheres like Anancus, none of which have gained any consensus. Nobody disagrees that Mammutidae and Deinotheriidae are monophyletic, and there are no effective common names for these groups, making the comparison irrelevant. "Gomphothere" remains the best title to contain this messy taxonomic group, as the term is as inclusive as possible, and does not imply acceptance of any particular classification scheme. Hemiauchenia (talk) 21:50, 23 July 2023 (UTC)

  Not sure if this is a good idea, but would it be possible to have separate articles for "Gomphotheres" in a paraphyletic sense and Gomphotheriidae the family proper then? PrimalMustelid (talk) 05:13, 26 July 2023 (UTC)

  I get where you're coming from, but the family is really inseparable from the concept of "gomphothere", and the fact is, "Gomphotheriidae" is inescapably paraphyletic due to the paraphyletic nature of the type genus Gomphotherium as currently defined. I simply don't think this is a good idea unless there are massive changes to proboscidean taxonomy in the future that attain some kind of consensus. Hemiauchenia (talk) 05:53, 26 July 2023 (UTC)
