It was assigned to Chondrostei by Schaeffer (1967) and Daly (1973); to Chondrostei by Uyeno (1978); to Actinopterygii by Lombardo (2002); to Osteichthyes by Sepkoski (2002); to Chondrostei by Nelson (2006) and Long (2011); to Actinopterygii by Nelson et al. (2016); and to Actinopterygii by Schaeffer and Dalquest (1978), Bürgin and Furrer (1992), Heckert (2004), Arratia (2015) and Schultze et al. (2021).
