Anybody out there know whether this name (or a similar one, such as Acrocanthus) might have been given to a fossil fish (by, say Agassiz) or other animal before 1950? I've searched with Google but keep pulling up the dinosaur. If Acracanthus were preoccupied, it would explain why they used Acrocanthosaurus in place of it when Stovall and Langston originally described it.
