Comments

Asineops squamifrons was first described by Cope as having an affinity to the pirat perch family. Later, with more detailed study, this species was found to lack the diagnostic characters of that family. Thus it is not yet clearly assignable to order. Although this species is much rarer in the Fossil Lake sediments than in Lake Gosiute deposits, the specimens from Fossil Lake are much larger than those from Lake Gosiute.
