Pycnodontidae is an extinct family of ray-finned fishes, ranging from the Jurassic period until the Late Eocene. It was the largest and most derived family of the successful Mesozoic fish order Pycnodontiformes, and one of only two families (alongside the Serrasalmimidae) to survive into the Cenozoic.
