Acestrus

Acestrus is an extinct genus of prehistoric bony fish that lived during the lower Eocene. It contains one species, A. ornatus from the London Clay, known from a single braincase. It is thought to possibly be closely allied with billfishbased on the braincase morphology, although it remains uncertain whether it had the rostrum characteristic of billfishes. Some authorities have suggested blochiidaffinities.
