I notice that you've proposed changing the notation on several pages. You might want to try WikiProject Physics for a centralized discussion. I also encourage you to join the project (WP:WikiProject Physics/Participants) if you aren't already part of it.Headbomb {^ταλκ_{κοντριβς} – WP Physics} 10:58, 19 February 2009 (UTC)

[edit] Anomalocarids & Co

I've tried to make the taxoboxes of these genera consistent. I did this in a conservative way, which I hope has most common support. An advanced way would perhaps remove the arthropods as direct subgroup of panarthropoda and place them close to schinderhannes (Devon), even closer than to anomalocaris (Cambrium). But may be this view gets more support with the time and taxoboxes should be reviewed then. --Ernsts (talk) 19:39, 10 March 2009 (UTC)

[edit] Opabinia

Thanks for your interest in the Opabinia article. However there are a couple of problems with your additions to the taxobox:

• The levels above "Kingdom: Animalia" are not supported by the cited sources.
• I'm not sure that adding "Sub-regnum: Opisthokonta" and "Domain: Eucaryota" is helpful to readers, and I'd only use those items at Animalia. While it appears the current consensus that animals (and fungi) actually are opisthokonts rather than a sister-group, so "Opisthokonta" as usually defined is paraphyletic, I would not care to bet on whether this will still be consensus in a few years' time, so I'd limit the number of articles that would need to be updated if there's a change. From a presentational point of view taxboxes are not a good medium for showing the whole of one branch of an evolutionary family tree, as cladograms can have an unlimited number of levels - try doing it for humans :-) --Philcha (talk) 09:49, 13 March 2009 (UTC)

PS if you think there's good reason to change taxoboxes for all these early critters, please discuss it at Wikipedia talk:WikiProject Geology/Cambrian explosion - unlike some Wikiprojects, the Cambrian Explosion Taskforce is pretty active. --Philcha (talk) 09:59, 13 March 2009 (UTC)
