An extinct bowfin relative with crushing jaws suited to invertebrates.
The genus Cyclurus is not known to have survived past the Eocene Epoch, possibly dying out about 35 million years ago. The closely related Amia genus survives today with the North American A. calva species.
The crushing jaws found on C. gurleyi specimens suggest an invertebrate diet.
