There is a separate tradition which ends up complicating things as  
some authors refuse to give ichno specimens taxanomic names.

 Actually the ICZN is very clear on its government over ichnotaxonomy  
every time animal taxonomy is discussed it also repeats that the same  
rules apply to ichnotaxa. A fossil trace can be used as the type for a  
taxon of fossil traces but a modern trace can not be used to name any  
group regardless of taxonomy or ichnotaxonomy. Disagreement occurs  
over whether or not we can use the terms for fossil traces to describe  
identical living traces with some authors saying yes you can and  
others saying that would go against the code.

Only in the aspect that they have their own traditions (some authors  
use an interesting system similar to the form and organ genera of  
palaeobotany) but there seems to be no formal agreed upon rules  
governing them.
