This page is a guide to writing pages about taxonomic groups.
"Taxobox"[edit]

We have found that a useful way to present the taxonomy of groups is with a small table (e.g. the ones right for Homo sapiens and Dromaeosauridae).
A "taxobox" can be added to pages to for any level of taxonomic group, following the styles shown in the examples.
This is the code you need to modify for a taxobox:
<div style="float:right;">
<table border="1" cellspacing="0" cellpadding="2">
<tr><th bgcolor="#CCCCCC">'''Group Name'''</th></tr>
<tr><td>
*[[Domain]]: [[Edit this]]
*[[Kingdom]]: [[Edit this]]
*etc, down to the group name
</td></tr>
<tr><td>
Subgroups (to one taxon level below the taxon being described)
* [[Edit this]]
* etc
</td></tr>
</table>
</div>
Minimally a Taxobox should contain the Linnaean ranks to which a species or clade belongs, each one nested inside the other. Where applicable, it may also contain phylogenetically defined groups.
Some notes:
- The group name should be the common name where there is one, as the latin name will be included elsewhere in the box
Phylogenetic Shorthand[edit]
The abbreviations for phylogenetically defined clades should follow the recommendations of the 2003 draft of the PhyloCode.
Node-based names are represented as [A: X and Y], or, the most recent common ancestor of X and Y and all its descendants. For example:
Aves: Archaeopteryx and Neornithes
Thus Aves refers to the most inclusive clade containing Archaeopteryx and Neornithes and all of its descendants. Stem-based names should be represented as [A: X not Y], or, all forms sharing more recent common ancestry with X than with Y. For example:
Maniraptora: Neornithes not Ornithomimus
Thus Maniraptora refers to the most inclusive clade containing all forms sharing more recent common ancestry with Neornithes than with Ornithomimus. Apomorphy-based names should take the form [A: X in Y], or, the clade stemming from the first form with character X homologous (synapomorphic) with the same character in Y. For example:
Avifilopluma: Feathers in Neornithes
Avifilopluma consequently refers to the clade stemming from the first form with feathers homologous with feathers in Neornithes. Stem-modified node-based definitions should take the form {A: crown clade [X and (X not Y)]}, or the common ancestor of X and all extant forms sharing more recent common ancestry with it than with Y. For example:
Neognathae: crown clade [Charadrius and (Charadrius not Struthio, Tetrao)]
So defined, Neognathae refers to the most inclusive clade stemming from the most recent common ancestor of Charadrius and all extant birds that share a more recent common ancestor with Charadrius than with Struthio or Tetrao.
