The following rather hasty classification scheme uses Linnean taxonomy and is modified from Carroll 1988, For the cladistic equivalent, see the dendrogram page MAK120317

Subclass Anapsida Osborn, 1903 (= Anapsida Williston, 1917) [1]
  Order Captorhinomorpha Carroll & Baird, 1972 [2] primitive, lizard-like Permo-Carboniferous reptiles
     Family Protorothyrididae Price, 1937 primitive persistantly conservative lizard-like types, Mid Carb to Early Perm, Eur & N Am
     Family Captorhinidae Case, 1911 small to large insectivorous to herbivourous forms with triangular heads and downturned premaxillae, Late Carb to Late Perm of N Am, EEur, Afr, EAs
      Subfamily "Captorhininae" paraphyletic assemblage of small, primitive, mainly single-tooth-rowed forms which resemble other generalized amniotes, Late Carb to Late Perm of N Am, EEur, Afr
      Subfamily Moradisaurinae Ricqlès and Taquet 1982 large, highly derived, herbivorous forms, Mid to Late Perm of N Am, EEur, Afr, EAs

Notes

[1] as paraphyletic stem taxon sensu Carroll, not a monophyletic clade sensu Gauthier, Resiz, etc. Replaces the "Cotylosauria" of Romer, Colbert, etc

[2] Carroll's doubly paraphyletic Captorhinida is here rejected; and the families Bolosauridae and Acleistorhinidae previously included under the Captorhinomorpha are included under the Anapsida proper
