Talk:Amargasaurus

Spines
In some places it says Amargasaurus had spines all along its neck, back and tail, possibly with a skin "sail". In others it says it was only in the neck (there's even a drawing) and no sail. Which is it, I don't know. Year of discovery also varies. Maybe 1984 was initial discovery, 1991 was formal identification. Experts welcome. --Pablo D. Flores (Talk) 23:26, 26 December 2005 (UTC)


 * Amargasaurus did have a kind of ridge that ran all the way down its back, but this isn't exactly the same as the neck "sail". The very elongated spines that make this dinosaur so unique are only found on the back of the neck; the main ridge seen over the back and tail is much lower, was almost certainly imbedded in skin (and probably fat or muscle), and can be found in other diplodocoids such as Dicraeosaurus and Apatosaurus. 70.210.243.141 (talk) 02:34, 8 April 2008 (UTC)

Alternative hypothesis?
Where would one find reconstructions of Gregory S. Paul's proposed hypothesis without skin sails? I'm trying to make an accurate sculpture, and finding accurate references is proving difficult...--75.38.63.39 (talk) 23:37, 30 December 2011 (UTC)

 * Speaking of alternative hypotheses, here's a new study suggesting Amargatitanis is a mature Amargasaurus, might want to have a look. FunkMonk (talk) 15:03, 24 July 2021 (UTC)
 * Can't find it, could you share the link? --Jens Lallensack (talk) 15:19, 24 July 2021 (UTC)
 * Oops, here, thought I had linked it above... Saw it on the dinosaur mailing list just before. FunkMonk (talk) 15:23, 24 July 2021 (UTC)
 * Thanks; can't download it at the moment, but will try to get it. --Jens Lallensack (talk) 15:43, 24 July 2021 (UTC)
 * I'm not sure it actually says that. It only says that the holotype of Amargatitanis represents a more mature individual than that of Amargasaurus. Lythronaxargestes (talk &#124; contribs) 15:22, 25 July 2021 (UTC)
 * Oh, I see, must have over interpreted "We interpret that Amargatitanis represents a more maturational stage than Amargasaurus". But I'm sure the paper goes into more detail, and should be covered here in any casde. FunkMonk (talk) 15:31, 25 July 2021 (UTC)
 * Seems it was because of the DML headline: "Amargatitanis possible mature Amargasaurus (dicraeosaurid sauropod)?" FunkMonk (talk) 00:34, 28 July 2021 (UTC)
