Ref: ITIS 82697

I think giving ITIS reference numbers for groups is probably a bad idea. We are not specifically following their taxonomy, which is often idiosyncratic though not for this particular group, and so there is no particular reason to single them out this way. -- Josh Grosse

I was actually emulating other group pages which use the ITIS scheme (eg Clover) and following the standards at Wikipedia:WikiProject Tree of Life which recommend that we cite our references at the bottom of the table, in the form "Ref: <source-abbrev> <page-name> YYYY-MM-DD". 'ITIS' is simply one kind of reference, there's nothing to stop us adding more references underneath (e.g. from NCBI or the "Tree of Life Web Project"). By including it we aren't really singling it out and saying it's the one and only "canonical" reference by including it at the bottom. We should definitely include as many backup references as possible. At the very least we should note the ITS number as backup reference in the Talk page. -- Lexor 02:02 25 Jul 2003 (UTC)

Pointing to things like ITIS and NCBI can be useful, but I don't think it makes sense when the classification is well-known and relatively well established. Just about any taxonomy base that covers arthropods would be a valid source here, not to mention printed materials - if someone wants to double check the system, they need only open an invertebrate zoology text or type Chelicerata into a search engine. If we want our references to be helpful, we should only include helpful ones. What might be worth including here is a sitation to the original definition of the taxon, if we can find it. -- Josh Grosse

Fair enough, but in that case, we should update the Wikipedia:WikiProject Tree of Life page and/or discuss the policy on Wikipedia talk:WikiProject Tree of Life to reflect this, because the current template/policy on that page suggests that references are part of the standard template format/style. --Lexor 07:24 25 Jul 2003 (UTC)

[edit] Eurypterids

I added a the class Eurypterida to the article, but it isn't alinged with the other classes. How can I fix this? Giant Blue Anteater 16:39, 21 October 2006 (UTC)

[edit] Taxobox photograph

I believe a sea spider is not a good example of a chelicerate. Many scientists are unsure whether they should be classified in this superclass. An arachnid(spider, scorpion, etc.)or horseshoe crab would be better, I suppose.--Crustaceanguy 21:45, 24 January 2007 (UTC)
