Talk:Eleutherozoa

merge with Stelleroidea
I've put in a modern phylogeny but am not confident enough with its foibles to update the article more fully, so I've left the article as it is (i.e. self-contradictory). Hope someone more familiar with the topic can update it! Verisimilus  T  16:24, 2 February 2008 (UTC)
 * I see no advantage in merging these two articles. Stelleroidea seems to be an order within the subphylum Eleutherozoa and deserves a separate page. The cladistics are unclear and subject to change and the present structure is as good as any other. Cwmhiraeth (talk) 05:20, 30 September 2011 (UTC)

Temporal range inconsistency
I could be mistaken, but I think the temporal range of this taxon is incorrect. It is stated in this article’s automatic taxobox to have Cambrian origins, but none of the classes within it have existed earlier than the Ordovician. What I suspect may have happened is that the temporal range was copied from the higher classification Echinodermata, but as far as I’m aware, this is in error as Crinoidea is not included within Eleutherozoa—while Crinoids certainly do have Cambrian origins, they are excluded from this taxon. The classes Asteroidea, Echinoidea, Holothuroidea, Ophiuroidea, and Somasteroidea, which are included, all come later geologically. Entelognathus (talk) 17:54, 14 March 2021 (UTC)
