Pycnodontoidea

Pycnodontoids were "deep-bodied and laterally compressed fish" whose tooth morphology suggest that they preyed on small contemporary invertebrates. They may have resembled modern butterfly fish. So far, Morrison pycnodontoids are represented by a single specimen from Dinosaur National Monument in Utah.
