Scientific Classification

Class:               Actinopterygii (Ray-finned Fish)

Order:              Istiophoriformes (Billfish)

Family:             Xiphiidae

Genus:             Acestrus

Species:          ornatus (Woodward 1901)

Acestrus ornatus is only know from a few specimens and sadly all of these are only partials. It is clear from the morphology of the top of the skull that this is likely to be a billfish but it is not clear what these would have looked like until a more complete specimen is found. Acestrus ornatus is characterised by heavy ornamentation (including deep grooves and striations) on the top of the skull.

Distinguishing Characteristics:
  • Sclerotic ossicle in orbit (1)
  • Deeply grooved ornamentation running down frontal bones on top of skull (2)
  • Centrally-radiating ornamentation (3)
