Your new Haya griva cladogram needs some fixing

Latest comment: 3 years ago3 comments2 people in discussion

Hi Meekororum, the new cladogram you added to Haya griva needs some fixing. It is a bit broken right before Kulindadromeus, which is causing Hexinlusaurus and Yandusaurus to not be shown. I added indents for each subtier to try to track down the error, and left a blank row where the error first appears so that it will be easy for you to spot the place where it needs fixing. I would have fixed it myself but I don't have access to the article you are referencing. Also, your new cladogram does not include Cerapoda, Marginocephalia, or Ornithopoda - I would think these major groups should be included. I added back the old cladogram (at least for now) in addition to your new one. Can you go and fix your new cladogram? Thanks Cougroyalty (talk) 14:49, 21 June 2021 (UTC)Reply

Hi, I haven't done cladograms in a while, which explains the errors but I will work on it soon. Meekororum (talk) 00:36, 22 June 2021 (UTC)Reply

I'm going to remove it from the main article for now, but I'll dump it here so that your work is not lost. When you get a chance to fix it, you can put it back.Cougroyalty (talk) 16:05, 30 June 2021 (UTC)Reply

In 2021, Daniel E. Barta and Mark A. Norell carried out a detailed analysis of the phylogenetic position of Haya. The cladogram below shows the results of their analysis, with Haya recovered outside of Jeholosauridae, and instead as part of Thescelosauridae.^[1]

Ornithischia

Pisanosaurus

Heterodontosauridae

Thyreophora

Neornithischia

Haya

	Parksosaurus

	Thescelosaurus neglectus

	Thescelosaurus assiniboiensis

	Thescelosaurus garbanii

	Notohypsilophodon

Orodrominae

Changchunsaurus

	Oryctodromeus

	Koreanosaurus

	Zephyrosaurus

	Orodromeus

	Albertadromeus

Falaises des Vaches Noires

Per Monvoisin et al. 2022 the stratigraphic provenance of most of the the theropod material in the cliff is unclear. Maybe the best solution here would be to merge the Marnes De Dives and Marnes De Villiers into a new article about the Falaises des Vaches Noires using the french version as a base, as ultimatley these specimens deserve to be indexed somewhere.

Yeah, that seems to be the best solution. Meekororum (talk) 00:40, 18 December 2022 (UTC)Reply
