Ornithodelphia
/ˌɔːnɪθə(ʊ)ˈdɛlfɪə/Zoology
noun
Treated as plural. A subclass or infraclass of mammals including the monotremes and sometimes also the extinct multituberculates.
Origin
Mid 19th century; earliest use found in Thomas Huxley (1825–1895), biologist and science educationist. From scientific Latin Ornithodelphia, subclass name (H. M. D. de Blainville) from ornitho- + ancient Greek δελϕύς womb + scientific Latin -ia, so named on account of the resemblance of the reproductive organs to those of birds.
