Balistomorphus is an extinct genus of prehistoric triggerfish during the early Oligocene epoch in what is now Canton Glarus, Switzerland. It inhabited the marine environment of the Tethys Ocean.[1][2][3][4]

Genus: Balistomorphus
Gill, 1888
Species
  • B. orbiculatus (Heer, 1865)
  • B. ovalis (Agassiz, 1842)
  • B. spinosus (Agassiz, 1842)
Synonyms
  • Acanthoderma Agassiz, 1842

The following species are known. All were formerly placed in the preoccupied genus Acanthoderma:[2][5]

  • B. orbiculatus (Heer, 1865)
  • B. ovalis (Agassiz, 1842)
  • B. spinosus (Agassiz, 1842)

Woodward (1901) considered all species synonymous with B. spinosus, but later studies have retained them all as distinct.[3][5]
