Critique
This taxon was erected by Marsh (1873) and later corrected by FŘrbringer (1888) to Ichthyornithidae. Initially Marsh ascribed two genera to the family, Ichthyornis and Apatornis. Analysis and review has shown that Apatornis may be closer to Neornithes than Ichthyornis (Clarke 2004). There is little point to defining this monotypic taxon until there exists additional taxonomic diversity.
