The Ichthyornithiformes are a group of toothed fishing birds. The most famous, Ichthyornis, is known from from the Niobrara Chalk of Kansas, as well as other sites in North America. They have fully developed wings, a deeply keeled sternum, and a reduced tail, although their jaws are still lined with teeth. It has been hypothesised that they would have behaved in a similar way to modern day terns.
