ClassificationEdit

The Ornithocheiroidea was originally defined as an apomorphy-based taxon by Christopher Bennett in 1994. It was given a relationship-based definition in 2003 by Alexander Kellner, who defined it as the least inclusive clade containing Anhanguera blittersdorffi, Pteranodon longiceps, Dsungaripterus weii, and Quetzalcoatlus northropi.[1] Later that year, David Unwin suggested a more restrictive definition, the clade that contains Pteranodon longiceps and Istiodactylus latidens.[2] Brian Andres (2008, 2010, 2014) in his analyses, defined Ornithocheiroidea using the definition of Kellner (2003) to avoid confusion with similarly-defined groups, like Pteranodontoidea.[3]
