Ornithurae is a natural group that includes modern birds and their very close relatives such as the ichthyornithines and the hesperornithines. This clade is defined in the PhyloCode by Juan Benito and colleagues in 2022 as "the smallest clade containing Ichthyornis dispar, Hesperornis regalis, and Vultur gryphus."
