Pegasoferae is a recently proposed superorder of mammals based on genomic research in molecular systematics by Nishihara, Hasegawa and Okada (2006). To the surprise of the authors, their data led them to propose a clade that includes bats (order Chiroptera), carnivores such as cats and dogs (order Carnivora), horses and other odd-toed ungulates (order Perissodactyla) and pangolins (order Pholidota) as springing from a single evolutionary origin within the mammals. According to this, the odd-toed ungulates closest living relatives are the carnivorans. Earlier theories of mammalian evolution would, for example, have aligned bats with the insectivores (order Eulipotyphla) and horses with the even-toed ungulates (order Artiodactyla). Subsequent molecular studies have failed to support Pegasoferae (Matthee et al., 2007; Springer et al., 2007).
