It was assigned to Mollusca by Yü (1979) and Sepkoski (2002); and to Maikhanellidae by Ponder et al. (2007) and Parkhaev and Demidenko (2010).
If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
