Hadrodus is an extinct deep-bodied bony fish known from the Late Cretaceous to Eocene of North America, north Africa, and the Middle East.  Paleontologists have stated that it is closely-related to pycnodonts but should be classified in its own family.

Hadrodus had anterior teeth that are rounded crushing-type teeth and strange hook-like teeth that formed a comb-like structure that might have acted like a strainer in the back of the mouth.
