That's why it's the usual way that critters are classified. Mammals have 
ALWAYS been considered a "reptile sub-taxon." That is until some guy decided 
to redefine the unilaterally term reptile. Prior to a couple of years ago, 
"reptile" meant all primitively ectothermic amniotes, and to many, if not 
most, workers, that still is the case.
