Its phylogenetic relationships have long been enigmatic, with it initially being classified as an indeterminate teleost, or more specifically an indeterminate clupeocephalan. However, more recent studies have recovered it as a basal crossognathiform. It is one of the earliest crossognathiforms known.^[4][5][6]
