“According to Scott (1961, p. Q84), the hingement of the Kirkbyacea resembles that found in the Kloedenellacea, suggesting a possible relationship between these superfamilies.”

“The genus Saipanetta has been suggested to be a surviving relict of the metacopidan superfamily Healdiacea because of its muscle scar pattern and narrow duplicature; nevertheless, it differs from the Metacopida in its more complex hingement, lack of a distinct contact⟳ groove, exaggerated domiciliar asymmetry, and lack of posterior ridges or angulations.”
