* others who have made the suggestion independently have also been 
ignored. If an age is associated with each category, then the use of the 
category for a monophyletic group becomes a falsifiable hypothesis, and 
rescues the notion of category from the stigma of Aristotelian 

I wonder, if this isn't to be done in an immediate convulsion, if the 
proposed age of the group could be appended, along with the author's 
name - e.g. class Mammalia (L; early Permian) - until consensus emerges 
on the ages of categories in each higher taxon, perhaps grading into a 
system where age alone is the categorical marker.
