Taxonomy: For all marine species, Project Gastropods uses the taxonomy in the online database WoRMS. When starting a new article, do not use sources of taxonomic information that predate the 2017 revision for all gastropod groups ("Revised Classification, Nomenclator and Typification of Gastropod and Monoplacophoran Families" by Philippe Bouchet & Jean-Pierre Rocroi, Bernhard Hausdorf, Andrzej Kaim, Yasunori Kano, Alexander Nützel, Pavel Parkhaev, Michael Schrödl and Ellen E. Strong in Malacologia, 2017, 61(1–2): 1–526.) (can be dowloaded at Researchgate.net), substituting the previous classification of 2005 Taxonomy of the Gastropoda (Bouchet & Rocroi, 2005).

History of this article prior to December 28, 2006.

Previous versions and edits may be found in the history of the Navel article. Please transfer the article history if you know how. James Kell 08:29, 28 December 2006 (UTC)[reply]

This is a very complex case, because the article "Navel" has undergone more than 1,000 revisions since 28 December 2006. I never had to deal with such a complex case where only a part of the article was copied and pasted into a new article, without transfer of the relevant histories. Chances are that the whole transfer may go awry. And to undo a bungled attempt is even more complex. It is probably best to leave things as they are or perhaps find an administrator who feels at ease with such a complex case. JoJan (talk) 13:56, 27 October 2012 (UTC)[reply]

I agree with you; I feel that this is hardly worth doing under the circumstances. Invertzoo (talk) 13:10, 10 November 2012 (UTC)[reply]
