It was assigned to Multituberculata by Simpson (1928); to Plagiaulacoidea by Simpson (1929); to Plagiaulacoidae by Hay (1930); to Multituberculata by Simpson (1927), Wood and Ormsbee (1954) and Gazin (1969); to Ptilodontoidea by Sloan and Van Valen (1965), Clemens and Kielan-Jaworowska (1979) and McKenna and Bell (1997); and to Ptilodontoidea by Kielan-Jaworowska and Hurum (2001), Scott et al. (2002) and Kielan-Jaworowska et al. (2004).
