The problem is exacerbated by the inadequate diagnoses of the constituent families; even the well-accepted clades within Ptychopariida, such as the family Olenidae, are united by few shared derived characters, and, as in the Asaphida, there are primitive representatives lacking some of the derived states, and advanced representatives that have.
