Gonorynchidae
Family of fishes
From Wikipedia, the free encyclopedia
Gonorynchidae is a family of ray-finned fish in the order Gonorynchiformes, which has a number of fossil taxa and one extant genus, Gonorynchus, the beaked salmons. They are an ancient group, with fossils known from as far back as the Albian stage of the Early Cretaceous.[3][4] The family name comes from Ancient Greek γωνία (gōnía), meaning "angle", and ῥύγχος (rhúnkhos), meaning "snout", referring to the angular snout that the type species use to dig themselves into the sand.
