@Wraith27143775 Though it has long been dead named for being misinterpreted as apatosaurus they actually reassessed it’s material and there’s enough distinctions that make it a valid genus again so it exists (again) https://t.co/WdKSqPPSLR
#MyFavoritePeerJPaper is a great example of how to combine careful anatomical observation, phylogenetic analysis and a numerical approach in order to establish the phylogeny and taxonomy of extinct organisms, in this case diplodocid sauropod dinosaurs!
@TPixel55 @SpahnCameron Diplodocus hallorum is the only diplodocine species with vertical mid-caudal neural spines. The other diplodocines, including Diplodocus longus, are found to have slightly posterodorsally directed neural spines instead.

Mais les 2 derniers n'ont été utilisés que sur l'original, pas sur les moulages. Et d'après une étude parue en 2015, le crâne ne serait même pas du Diplodocus, mais un autre genre : Galeamopus. Du coup on ne connaît peut être AUCUN crâne de Diplodocus!
@PPaleoartist @tyrannoraptoran here’s a *very* simplified timeline showing when Brontosaurus became a valid genus again actually a few years ago, and here’s the paper that actually made the split https://t.co/ypQh8zFmkH https://t.co/9wiewiDFFC
@Michael_Tomlin_ @king_tyranno @ArminReindl @Strangeandlosts Brontosaurus history can be confusing, we know that the animal existed, there was just debate on how to call it. After this paper we now consider it a valid genus: https://t.co/sWvQTfup4u
@Marcelo_Cassaro @_pmnetto Na saudade fui dar uma lida por ai e descobri uma boa noticia (daquelas que são boas pq não mudam a vida de ninguem rs): o brotonssauro ta de volta. Um trabalho taxonomico de 2015, da família Diplodocidae restaurou Brontosaurus como um gênero válido:

@Epicureo64 Eso si te fías de los métodos estadísticos para extraer árboles filogenéticos, que hay quien los critica. El paper está aquí en abierto: https://t.co/EApxxzditW
