Mammaliaformes

Translingual Etymology mul Mammalia iformes Proper noun clade order Therapsida Usage notes Ranks are sometimes assigned to well-studied lines of taxa, such as those leading to Homo genus. As the assignment of 'order' to Therapsida order and 'class' to Mammalia class (placed under Therapsida) shows, they are no longer of much utility. The clades themselves are periodically invented and reinvented, defined and redefined, circumscribed and recircumscribed, and sometimes abandoned.
