Ichthyornis dispar (Greek for Fish Bird, named after its fish-like vertebrae) was a species bird that inhabited modern-day Canada and the United States during the mid Cretaceous epoch.

Ichthyornis lived mainly in the seashores of the Western Seaway. Stomach contents indicate its diet mainly was comprised of various fish, small animals, and carcasses. It was a toothed bird, having small sharp teeth lined in its jaws, and possessed a similar ecological role to modern day, gulls, petrels, and skimmers. Ichthyornis measured approximately nine inches in length with a skeletal wingspan of roughly 17 inches.
