Ichthyodectes was a bony fish of the order Ichthyodectiformes, which in addition to Ichthyodectes includes the giant, Xiphactinus and smaller Gillicus. Large ichthyodectes grew to more than 10 feet long and were a one of the principle predators of the Western Interior Seaway during the late Cretaceous Period.
